User questions & answers

Question:	I ordered one of these but can't seem to find info on how it actually hooks up to the propane tank. Also, does it come with a tank
Answer:	It does not include a tank. You can get a Mr Heater hose that is 3/8 npt on one end and a tank fitting on the other end. The inlet on the heater is 3/8 npt.
Question:	Can this heater run with only the pilot flame on
Answer:	It is self-contained and automatic. The pilot setting will keep only the pilot burning. In heating mode it will automatically turn on and off at the desired temperature. The optional fan is not required but does not need to be plugged in if installed.
Question:	Does this have plate for built in fan
Answer:	Yes. Also wired for the fan so it is thermostatically controlled. Fan sold seperately.
Question:	How low can the thermostat be set? Can it keep a room just above freezing
Answer:	I use it to supplement my forced air heat. I would imagine in a room that is prone to freezing with the unit on it's lowest setting it would cycle quite a bit. It definitely kicks out a lot of heat.
Question:	How long will 20lb propaine last on lowest setting in insulated room
Answer:	Say a 10' x 10' room; about 12 to 16 hours. You MUST have some fresh air coming into the room or the O2 depletion will shut the heater off. Propane need air to burn just like most flames.
Question:	Is this safe in a 300 square foot cabin as the sole source of heat
Answer:	This is very large for a room of that size. I would recommend the 20,000 BTU model. That is ASIN B01DPZ5B3. These are designed as supplemental heat but it could be used for your application.
Question:	Does this product have built in regulator
Answer:	You must use an external regulator. You need some other hardware if you are going to use it on the floor. Here is what you need: ASIN:B0002YPAFY Rectorseal 23631 1/4 Pint Brush Top T Plus 2 Pipe Thread Sealant, ASIN:B0058DIGPU Anvil 8700137808, Steel Pipe Fitting, Nipple, 3/8" NPT Male x 4" Length, Black Finish, ASIN:B005R21QLS Mr. Heater 12-Feet Hose/Regulator Assembly, P.O.L. and Hand Wheel x 3/8-Inch Female Pipe Thread. If your heater did not include an elbow, get a 3/8" ASIN:B005C2U67I Anvil Malleable Iron Pipe Fitting, Class 150, 90 Degree Street Elbow, NPT Male x NPT Female, Black Finish. Put sealant on the outside threads only. Screw the elbow into the heater so that the opening faces the front of the heater. Screw the nipple into the elbow. Attach the feet that came with the heater. Screw the hose onto the nipple. Attach the other end of the hose to your propane tank. Check all connections with soapy water before lighting.
Question:	Will this burn in high elevation
Answer:	Yes as long as there is enough oxygen. Oxygen above 12000 feet altitude becomes thin and supports combustion less efficiently.

Blue Flame Vent Free Heaters

Our Vent Free heaters need no external power, great for power outages and applications with no electricity. They can be mounted to the wall with the supplied bracket or on the floor with the supplied feet.

Most common uses are rooms that don’t warm well so you can adjust the temperature level in them without having to affect the rest of the home.

There are two types of vent free heaters, blue flame (or convection heat) and infrared (or radiant heat). The difference in these types of heat are how the warm.

The Blue Flame heater warms the air. It doesn’t radiate the heat like an infrared unit. It can be put in a narrow area because the heat rises and warms the area from the ceiling down. Blue Flame warms the air, infrared warms objects, which heat the air.

Note: Units cannot be converted from Propane to Natural Gas and vice versa. They are not designed to be a primary source of heat, as they are designed to work with a furnace.

User questions & answers

Question:	Will unit work with 20 lb propane tank
Answer:	I agree that the 20 gal. tank won't last very long...........we have ours hooked up along with several others, to a 1000 gal tank. Works great there....
Question:	I am looking to use something like this unit for backup heat for all electric house. Can this be hooked up to a LP gas bottle like on a charcoal gri
Answer:	Yes. Just make sure the unit is configured for LP. Thes units can also work with natural gas but it is an either/or situation. A 30K BTU unit will burn through a 20 lb (grill size) tank in 2-3 days depending or demand. Good idea to test usage before you actually need it.
Question:	how many square feet will it heat
Answer:	I heat 900 square feet insulated garage in bitter cold northern Minnesota on the 1st setting. I have had to turn it up to 2nd setting for some people to be comfortable. Its a great heater very happy with it.
Question:	I'm purchasing this heater to hook up to a large outside propane tank w/ regulator. Do I need to purchase the hookup kit
Answer:	you should have your local propane provider run the necessary piping if none exists yet. If it is already set up, you should be able to tie into the tank yourself, but check out the local regulations, as you may have to be a licensed plumber to avoid any insurance issues should something go wrong. At any rate you should not need the hookup kit.

F270125 Features: -Forced Air Propane Heater. Specifications: -75,000 - 125,000 BTU.-Heats up to 3,000 Square Feet.

The MH125FAV is the least powerful of Mr. Heater's line of propane forced-air heaters for larger jobs (see the MH170FAVT and the MH400FAVT). Even so, it still gives you up to 125,000 Btu--enough to heat 3,000 square feet. Though the larger models give you more Btus, the heaters in this line share the same basic features, including an automatic shutoff with loss of flame or power supply and a high-output fan that circulates heat quickly. Hooking the heater up to the 40-pound propane cylinder (not included) is easy, and the 10-foot hose and regulator are included. CSA certified. One-year limited warranty.--Josh Dettweiler

Five Tips for Buying a Heater

Choosing a space heater is a matter of sifting through a bewildering array of types, power ratings, and fuel sources. Let's break it down a little to make the process easier.

What are the different types of space heaters?

• Radiant heaters emit infrared radiation that directly warms the objects in front of the heaters (rather than the surrounding air). If you only need heat by a desk or in a small section of a room, a radiant heater is quiet and will use very little power.
• Forced-air heaters use a fan to blow air that has been warmed by metal or ceramic heating elements. A forced-air heater is appropriate for quickly heating up a small- to medium-sized room, but can be noisy.
• Convection heaters draw cold air from the floor; the air is warmed by heating coils and emitted from the top of the heater. A convection heater is appropriate for quickly heating up a small- to medium-sized room, but also can be noisy.
• Radiators work by heating oil enclosed in a reservoir, gradually heating the surrounding air. If heating speed isn't an issue, you might want to opt for a radiator. These are extremely quiet and effective--perfect for bedrooms.

Should I buy an electric or a combustion model?

If you want a heater that will be available in emergencies, or that can heat areas larger than a single room, choose a "combustion" model--one that is powered by a gas or fuel like propane, kerosene, natural gas, or diesel. Which fuel type you choose depends largely on convenience and local availability. For example, diesel would be appropriate for a heater you take with you on long car trips.

How powerful a heater do I need?

Heaters are rated by BTU, which stands for British Thermal Unit (the amount of heat needed to heat one pound of water by 1 degree F). To find out how many BTU you need:

• Calculate the volume of the space to be heated by multiplying square footage by height.
• Multiply that number by 4 if your insulation is poor, 3 if it's average, or 2 if it's good.

The resulting number is a ballpark figure for how many BTU you'll need.

Do space heaters cost a lot to operate?

As a general rule, electric space heaters are more expensive to use than combustion models. To ensure energy efficiency, a thermostat is a must-have feature for any heater. For radiant heaters, models with a 360 degree heating surface can heat larger spaces. If you need a forced-air heater, models with ceramic elements tend to be more efficient.

Are space heaters a fire hazard?

Space heaters are implicated in about 25,000 residential fires every year. To ensure proper safety, always follow the manufacturer's usage instructions and fill out the warranty card to receive informational updates from the manufacturer. Also, look for extra safety features such as an automatic shutoff switch that can shut down the unit if, for example, it gets upended. In addition, choose a model where the heating element is adequately enclosed within the unit.

User questions & answers

Question:	Will this item work with a 20 Lbs tank
Answer:	It will work, although your run time might only be a day. The new 20 lb tanks have the overflow restrictions that limit them to only 80% fill. I use a 100 pound tank and run mine for about 15 minutes to get the chill out of my 600 sq foot garage. Just realize that the tank connections are different for the two tanks. The 100 pound tanks use the old connection. Also in my state you can only fill the 100 pound tanks if you have a pickup. The tank can't be in a van or car. (Any place where passengers are.)
Question:	I want to use a portable electric generator for the fan. What is the current draw for the electric fan
Answer:	If you scroll down the page a bit, in the "Product Information" area, to the right of that under "Technical Specification" is the user manual. The info you are looking for may be there.
Question:	I need help looking for a Christmas gift. Is there a difference between a forced air heater and a torpedo heater
Answer:	Forced air and torpedo heaters are the same. Both use a blower fan to circulate the air and can be quite loud however they warm an area quick. Convection heaters use no fan but for the same heat output take longer to warm a space. They are much quieter. Neither should be used continually in an unvented area.
Question:	How fast does it go through a 40 gal tank
Answer:	I use a 20 Lb tank, which usually lasts me about a week. I use the device to heat a 24 x 36 insulated garage. The usage life is directly affected by the outside temperature. It's been really cold here (upper Michigan), so I may not get that much usage from a 20 pound tank.

Answer:	Yes..it should have the warranty information down in the description/information section where you are looking at this particular item.
Question:	How well does the thermostat work? Would like to leave this unit on in the garage and maintain a set temperature
Answer:	Thermostat works well. It's not a set temperature thermostat though. You pick a number or in between spot that feels comfortable and leave it. I never leave it on overnight though.
Question:	What are the pros and cons of infrared verses convection nat. gas heaters
Answer:	Infrared is much warmer to me. We ordered 3 heaters before we found this one. It is the BEST and worth every penny that we paid for it. It heats quickly and evenly. I will never own another brand of heater.

User questions & answers

Question:	why is this advertised for in home use when the instructions specifically sate this is a life hazard
Answer:	A few factors enter into whether you can use this inside your home. I have been using mine in living room like a fireplace for 4 years now. My house is over 100 years old, with old windows so I get alot of oxygen coming in through them. I use a 20lb tank I bought new with a hose & regulator. Every time I get it refilled I use a gas sniffer I bought to check all the connections. The only time I have it on is when I'm in room watching TV. They have to say don't use it inside in instructions to protect them from lawsuits from people who are careless.
Question:	Would this work for a baseball game. Or do you need some sort of enclosure to trap heat
Answer:	The Big Buddy id designed to be used in enclosed spaces and won't heat a large space outdoors. However, it could take the chill off those who are sitting reasonably close to the front of it, especially if the built in fan* is used to blow warm air towards the user(s). *The Big Buddy's fan can be run on batteries placed in the back of the unit or with an electrical adaptor that can be purchased separately on Amazon.
Question:	Does this have a safety shut off and low oxygen sensor
Answer:	Yes. It will shut off if tipped over or low oxygen (although that has not happened).
Question:	how long does it last? If I use it in my shop can I leave it running overnight at a low setting so my stuff doesn't freeze? Thanks in advance
Answer:	With this on "Med" so 1 burner is bright red, you burn 1 pound of gas in 3 hours. Having it on low will burn about 1/2 that, so 2 small tanks could last 12 hours. Connecting a refillable tank may be well worth it since those small tanks are $3 each for 1 pound (or a quart or propane), you can get tanks refilled for $3 a gallon. Hoses like the F271803 or F273704 will connect this up to a refillable tank.

User questions & answers

Question:	Does the thermostat allow you to set the air temperature so thst the unit comes on automatically whenever the ambient air gets colder
Answer:	Yes but not exactly. You cannot set a specific temperature. The lowest setting is about 60 degrees and each subsequent number is about 5 degrees warmer. The last setting keeps the unit on continuously.
Question:	I need a replacement for my bathroom heater and need to know the size of this heater and can it be used to replace a vented one
Answer:	23.8 x 11.2 x 27 inches Yes, it could replace a vented one, although it doesn't require a vent according to the design. But in all reality they do because they are oxygen hogs and small spaces are not optimal for it to breathe and you'd basically have to leave that existing vent open and even then it might rob the room of oxygen. I wouldn't use in a bathroom, if vented worked I'd get the same thing.
Question:	does the unit emit a lot of heat from the back ? I am concerned about mounting the unit on the vinyl siding inside the enclosed front porch
Answer:	The back of the unit is not the problem, it's fine. It's the heat coming out the vents on the top front...we do have our heater mounted on our vinyl siding on the back porch. When the flames are on, the siding above the heater does get hot, not the sides or the back. The first time we were enjoying our "heated" porch after having the heater installed by a professional I noticed the siding looked funny...felt it, yup, it was hot, hot to the touch...great, now what....the heater is installed....we solved the problem by using a fan. We mounted a small fan off to the side above the heater facing the wall so it blows the "heated air" coming out of the vents away from the wall....not the correct way I'm sure but it took care of the problem without having to take the heater out. The heater is not on when no one is on the porch. Had we known before installing the heater we would have taken steps to put up a fire barrier of some sorts that would work correctly from the start....or perhaps mounting it further away from the wall than ours is set, which is about 3/4 to inch away....the heat goes right up the wall....on our other porch we have a heater also but it is on legs and sit about 6-8 inches away from the wall and there is no problem with the wall heating up. I hope this helps.
Question:	Can mr. heater provide me with an accurate ppm reading for this heater? accurate carbon monoxide meters: senorcon or pyle
Answer:	No. I installed a separate CO monitor on the opposite wall about 15 feet away from the heater as instructions recommended. Readings have remained at zero.

User questions & answers

Question:	Can I store the smaller, 1lb propane tanks on my terrace porch, possibly in a box, overall? in cold winters and hot summers
Answer:	For maximum safety, my recommendation is to store propane containers in a weather protected location, such as garage or shed with some natural ventilation. Propane is a highly flammable liquified petroleum gas that vaporizes and expands many-fold very quickly if released to atmospheric pressure, and will form a highly explosive mixture if released in a confined space without outside ventilation. If then ignited by a small spark such as a light switch, the resulting explosion may be catastrophic. There are on-line photos of boats that have exploded from propane leaks in the confined space of a boat cabin with catastrophic results including death of occupants. The cabin top and sides have literally been blown to pieces in such cases. New, sealed bottles of 1 lb size are reasonably safe, but once opened or partly used it is best to store away from occupied spaces. Although the probability is low, the consequences of failure are unacceptable. 20 lb propane containers should never be stored indoors. Play it extra safe and store propane bottles in a garage or outdoor shed. BJG (PE, ichemical engineer, inactive, retired)
Question:	can i hook a large propane tank to his
Answer:	Yes, any size propane tank can be a source for it when plumbed correctly. The simplest way to go is using the F273704 hose directly off most tanks. That hose needs nothing else and goes direct from the tank to the heater. This model heater only accepts high pressure gas thru the "disposable tank" connection, so other hoses with that connection can be used as well as the "filter" F273699. The "filter" is to take out oils coming from most rubbers in hoses where the high pressure "squeezes" the oil out, but the 704 hose is made "oil-free" to avoid that issue. FYI I tried running this off a regulated low pressure source, but with it on "high" the glow was like "low" setting normally (showing a lack of gas coming thru). So if you have a low pressure source, the "Big Buddy" models have a connection point for such thru a quick disconnect using hoses like F271802 or F271803, but not this model (this one needs high pressure gas to get enough thru it's disposable tank port).
Question:	How long with the heater run on low with a propane small cannister
Answer:	Best guess is 4-5 hours on low. I sat in a hunting blind for 2.5 hours and the 1lb propane canister was about half empty.
Question:	Does anyone know or understand how is it this type of propane heater can be used indoors without causing carbon dioxide poisoning
Answer:	As soon as the weather gets cold, I put my Big Buddy Heater on a stand & use a Mr. Heater 12' hose with regulator running to a 20lb. tank in living room. I use the hose with the low pressure regulator on it & hook it up to the quick connect fitting. I have 2 20lb tanks in mint condition, and rotate them as needed. This will be my 7th winter using it. Old windows & doors let air in and I have a carbon monoxide alarm near by. Also use a leak detector to check all connections after hooking up a full tank. If it's really cold, I'll start it on high for a short time, then run it on medium & it keeps living & dining room warm. Cuts my oil bill down greatly.

User questions & answers

Question:	if it has a thermostat, what temperature is it shutting off? I have a different fire place with a 73 degree shut off manufacturing setting,not enought
Answer:	I asked the manufacturer for the thermostate info. It has a knob on top from 1-5. 1-60.8°f 2-75.2°f 3-89.6°f 4-104°f 5-118.4°f He also said that they could vary slightly from heater to heater.
Question:	I don't see a pic or anything that shows where/how the fan mounts. Does anyone know
Answer:	The fan will mount on the back of the heater. There is a punch out that will be removed and the fan will go in it's place.
Question:	Would this heater work in a 2 car garage
Answer:	In short yes. we have this on the first floor of our house. it is not yet winter, but this is a 30,000 BTU heater; it heats the entire house fast - like 20 mins upstairs and down. I would say the same for a two car garage. I plan on moving this unit to the basement shop which is exposed to ground level in the back and unheated; basically a 1 car garage back there and I expect this to out perform. I will add one thing: this is the blue flame unit. I have had shop heaters before and prefer the radiant heaters (of which Mr Heater makes one just like this) - they have the clay looking elements in them that glow red/orange; those heaters will heat things in the space and then those items give off the heat. I used to aim one at my roll away tool box. in an area where you might have a lot of space up above, such as a loft the radiant version of this heater may be better as it will heat the items it is near with less heated air floating up. either way, this is a safe bet.
Question:	Does the mhvfb30ngt unit have an automatic igniter to maintain temperature or do you to to push an igniter switch to start it each time
Answer:	It has a pilot lit that will stay lit at all times, unless you turn the dial to the Off position. The heater will start up when the thermostat dial settings determines that it's time to turn the heater on.
Question:	I stripped the threads on the heater, how can i fix this
Answer:	You can tap it out if you have a tap and die set, otherwise you will have to order new parts
Question:	Want 30000 Btu radiant heater with blower
Answer:	The 30000 BTU heater will be the model number MHVFRD30LPT. Click on link provided to view the heater. https://www.amazon.com/Mr-Heater-Corporation-Radiant-MHVFRD30LPT/dp/B01DPZ56KU/ref=sr_1_1?ie=UTF8&qid=1514918538&sr=8-1&keywords=MHVFRD30LPT
Question:	Will this work with a 20 pound tank
Answer:	Yes, but you will need to add a regulator between the heater and the 20 pound tank for safety
Question:	So, it has no thermostat but output is variable? How does this work
Answer:	It does NOT have a thermostat, settings are either high or low. It will NOT turn on and off on it's own when reaching certain temperatures, it even says its NOT thermostat controlled in the manual.

Radiant Vent Free Heaters

Our Vent Free heaters need no external power, great for power outages and applications with no electricity. They can be mounted to the wall with the supplied bracket or on the floor with the supplied feet.

Most common uses are rooms that don’t warm well so you can adjust the temperature level in them without having to affect the rest of the home.

There are two types of vent free heaters, blue flame (or convection heat) and Infrared (or radiant heat). The difference in these types of heat are how the warm.

The Infrared heater warms objects. It doesn’t warm the air like a Blue Flame. It can be put in an area with objects which the heater will heat and then the object will heat the air. Blue Flame warms the air, infrared warms objects, which heat the air.

Note: Units cannot be converted from Propane to Natural Gas and vice versa. They are not designed to be a primary source of heat, as they are designed to work with a furnace.

User questions & answers

Question:	Does this one have a thermostat n blower
Answer:	Yes a blower and a thermostat.
Question:	I would like to use this at a cabin that is at 10,750 feet above sea level. Most appliances have to be ported differently. Will it work
Answer:	Yes but the mfg discusses elevation in the paperwork that comes with unit. I would call them
Question:	The specs do not list a blower. blower is mentioned is in the q&a section only. does it really have a blower? if so, why isn't it in the specs
Answer:	Thank you for your inquiry. A passive non forced air blower is available with all our vent free heaters 20K or larger. It is a purchase ad on.
Question:	How long is the blower power cord
Answer:	About 5 feet
Question:	Where do i buy natural gas for it
Answer:	You tap into an existing gas line
Question:	sq ft insulated garage (including garage door). Would this take care of warming up the garage
Answer:	I believe that it would. I have it in a 200 sq ft room with 13 ft ceilings, the house is 118 yrs old w/no insulation and it works very well. I do have the bigger size in another room.It has 3 burners instead of 2 and you can turn on 1,2 or all 3. It heats 2 rooms I have.
Question:	Is it possible to use with a thermostat rather than the low and high settings
Answer:	The heater is not designed to be used with an external thermostat.
Question:	How are the fumes vented ? I don't understand how you can burn something and not have to worry about carbon monoxide
Answer:	The fumes are not vented. Natural gas is mostly H₂, gasoline is about 50% carbon, coal is all carbon. So being mostly H₂, the combustion products are mostly H₂O with a little CO₂, not unlike what we breath out. Coal and gasoline will asphyxiate you fairly quickly because of the high carbon content, which must be vented outside.

User questions & answers

Question:	Can i hook up to my unvented propane log gas heater
Answer:	Yes, you can use this to hook up your log gas heater. GlobalTowne is an authorized Mr. Heater distributor.

Answer:	Mr. Heater F271239 One-Stop Universal Gas-Appliance Hook-Up Kit is a suave kit designed to give the consumer any possible gas connection, and has several different sized gas fittings. You should be able to connect directly to your propane supply line with ease.
Question:	my gas heater will light but will only stay lit for a short time. I've cleaned. the apiture. with alcohol. but that doednt seem to help. long term
Answer:	The oxygen sensor may be turning it off. Make sure there is airflow around the unit. At altitudes of approx. 4500+ it may shut off for much the same reason. Blow out the Aperture with air. There is a little hole down on the gas nozzle for that purpose. Canned air is best. A compressor may break something. I had a friend who just blew it out with his breath and it worked better. Clean the entire unit of dust and debris. Check the gas debris pipe and empty the sediment. Check your bottle, it may be near empty, or the control valve may be partially closed.
Question:	Is the valve 1/2" FIP to 1/2" flare? Is the connector 1/2" ID? What are the EXACT specifications on each of the adapters? Shocked it sells W/ no info
Answer:	The description says 3/8 and 3/8 but the one I got was 1/2 x 1/2 with adapters. It says universal but for me probably not since I actually needed 3/8 female and this only comes with 3/8 male so I will have to spend more money to make this work.
Question:	Can you HANG this from something
Answer:	YES you can hang this heater. It's been done. https://www.youtube.com/watch?v=AZsVX6mh8O4
Question:	Does anybody have trouble lighting this heater? Seems I need to hold the ignition button in for a minute and it really hurts my thumb
Answer:	Hey Spike, I agree with Thomas W. Mine wouldn't start on the first try either. You have to hold the ignition button down, wait a few seconds, then depress again. It's kind of a pain, but it works. A more annoying issue for me was wanting to use it in my golf cart, but with every tiny bump, the safety feature kicked in and off it went. So, it is safer for home use. For the cart, I bought the Coleman Catalytic Heater with the special holder that fits in the cup holders. It's more quiet too. Stay warm!
Question:	With an adapter hose can it be used with a large propane cylinder
Answer:	Not a problem. Make a 10"x10" box. Nail 2x6 together in the shape of a U. Then put 3/8" inch plywood on top and bottom (3/8" a must on top). Then make a 2 1/4" hole in the center of the top plywood. Next screw the main heater assembly into the filter with the top plywood in between (the two should come together snug leaving a very small separation which will allow the heater to rotate with no chance of a leak but still be secure). Then attach the hose and tank. This box allows for a large tank to be attached, the heater can rotate and the tipsy problem is gone.. Just remember to turn off the tank first to burn up the gas in the line before turning off the heater.
Question:	Has anyone used it tent camping? I'm afraid of fire and fumes, but the cub scouts insist in camping in sub freezing temps
Answer:	I used it last summer (2017), at night We went to bed late around 1:00 am, and usually by 5:00 am the 1lb tank is already empty and it's went the temp is the lowest, I spent about a tank per night, kept our 8 person tent warm, we have ventilation at the top and all the heat went up but I rather have ventilation that non at all, I'll probably wake up at 5 and replace the propane tank. We camped I bigbear, CA and it was cold at night, I might try an electric heater plugged into my Honda but still you have Carbon monoxide coming from the generator.

User questions & answers

Question:	It warns against using in elevations higher than 4,500 FT. Have you had success at
Answer:	Yes, there have been units with success over 4,500 ft, what this means is we aren't able to guarantee successful operation of these heaters are higher than 4,500 ft.
Question:	How many hours or days will it run with a 20# bottle
Answer:	I recently insulated a 14’ x 20‘ workshop attachment on my garage. I got this heater and before I bought a big tank I tried it on a 10 pound tank from my grill. It was set on number one setting the temperature outside was in the 30s and I got 64 hours out of it holding just over 60°. So I figure a 20 pound bottle should last me little over five days. So I’m going to get a 30 pound bottle that way I only have to refill about once a week. Warmer weather less often, I hope this helps.
Question:	It dont tell the dimensions? Is it 20" wide
Answer:	The dimensions for the heater are 23 3/4" W x 11 1/4" D x 27" H.
Question:	Can u use propane tank from a grill and how long would it last
Answer:	Quick math says about 17 hrs on full tank. This heater has a high and low output, controlled by the thermostat, not the user. One gallon propane would last approx 4 hours. A full 20 lb tank holds about 4.5 gallons.
Question:	how long does it last on a small propane tank
Answer:	The 1# tank will ice up and slowly turn off the heater on anything but the lowest setting. That lasts about 2 hours. A little buddy heater with 4K/9K Btu works best with the 1# cylinders. I have the hose hookup for a 20# tank and it's nice to have the option of using either size. You have to light this one with a lighter which is just another thing to forget to pack.
Question:	Just tried to make coffee on it and the grill started to collapse is there a sturdier grill for it
Answer:	As far as I know... No. A simular thing happened to me. I reattached the grill using good old fashioned wire hanger twisted. This was only a temporary fix.
Question:	Did anyone get the "foot" for the 1 lb. bottles and is it a worthwhile add-on
Answer:	Not sure what you're referring to. The one lb. bottle hangs suspended when connected. I wouldn't recommend getting this model. Get the model MH12C if you can. The regulator broke after a couple months and I couldn't return it. Instead I bought the regulator that was for the MH12C and adapted it to fit the MH15C. Since then it's been working great for a year. I also recommend purchasing the hose adapter so you can run off a 20 lb. bottle. It'll last a lot longer
Question:	how long does a 1lb bottle last compared to a 20lb bottle
Answer:	A one pound bottle on medium setting will last about 1-1/2 hour so figure at least 25 hrs for a 20 pounder.

User questions & answers

Question:	Can you use gas station diesel with this heater
Answer:	You are able to use diesel #2 with this unit.
Question:	Can this heater be used indoors without venting when using diesel? I have seen mixed reviews on the odor when using diesel but more opinions are nice
Answer:	I use one indoors in a 1900 ft2 shop. Mostly I use diesel fuel but ignition with straight diesel is problematic with this and most multi fuel units. Diesel actually burns hotter and cleaner (less smell) than kerosine. I mix about 3 gallons of diesel with 2 gallons of kerosine. It a hotter cleaner burn that costs a lot less than straight kerosine.
Question:	Does this use a wick like smaller kerosene heaters do
Answer:	No, totally different burner type. It uses a powered pump/burner assembly and blows heat out one end, brings in burner air from the other end. Called a "salamander" heater in the construction trades. Also is MUCH noisier than a wick type heater!
Question:	How long does a fill tank last
Answer:	About 6 hours. Takes a tank and a third to run a 9 hour day.
