User questions & answers

Question:	Can this unit be installed through a cut out in the celing so it points down towards the floor while having the majority of the unit in the attic
Answer:	Highly unlikely. The louvers on the front that direct air flow have maybe 45 degrees of downward angle. This just seems like a bad idea
Question:	does it smell when running
Answer:	not after initial burn period .Very quiet compared to my last heater ,does not smell .
Question:	Can it run on a propane tank for a gas grill
Answer:	This heater can run on a gas grill propane tank. Make sure the propane conversation kit has been installed and then you'll need to use a grill hose that has the regulator on it. Then you'll have to change the fitting after the regulator.
Question:	One description says heats 700 sq ft another says 1250. Which is it
Answer:	It heats my 900 sq. ft garage nicely.

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.

Question:	Only $489.00 at Lowes, why more expensive here
Answer:	$469 at Lowes :)

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.
Question:	Can we use this hook up for propane
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:	I'm looking to put a natural gas heater in my bathroom so which one could I put in it
Answer:	I'm not sure what you mean by which one. This one as best I can remember came with feet, but is very on the back and sides and could be wall mounted. Unless you have a very large bathroom or no other heat in your house this heater would be very adequate. I love mine.
Question:	Can this be used in an rv
Answer:	It would be dangerous to run this in such a confined space. I live in a large old drafty house and the heater is in a room 16x16 foot room that has 14 foot ceiling. Get a heater designed for and RV. Ideally electric to reduce risk of asphixiation....
Question:	Can it be connected to an exhaust vent for the gasses
Answer:	It has no exhaust port. It's made to be safe (like a gas oven) not having a vent. I use my to pretty much heat my whole little house and have never noticed a problem. Many gas fireplaces are made the same way.
Question:	does anyone know if there is an optional blower for this unit
Answer:	No. On't the 20k and 30k btu versions can use the optional blower.

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.

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:	I know it says it has a fan but Mr. Heater removed fans from some models. Is this one of those models
Answer:	The low voltage fan and switch IS NOT on this unit. There is a kit that can be ordered from another party that consist of the entire rear panel. It has the wiring an hardware attached to it with the switch, battery case and external low voltage plug for a transformer power supply. It is as simple as 4 screws to install. Mine was under $40. I could not find this larger heater WITH the fan anywhere. Many say it has the fan in the remarks but is not included. I hope this helped. Jack, Dayton OH.
Question:	Is this safe to use indoors? Like gas wise
Answer:	Many fear that anything burning gas will be like running a generator indoors that will kill you in 10 minutes. I understand such a concern, but this is much more like someone running a gas stove burner used in half the houses, that doesn't kill anyone in 10 minutes while warming water for coffee or such (does it?) It burns clean enough that there isn't the carbon-monoxide like from a generator. I ran the smaller version (Buddy) for 24 hours to do a "power outage drill" with freezing temps out to see what it's like with a CO detector set up, the CO unit never went off. I did go outside a few times like to get the mail and when coming back inside I could smell a bit of the "Burned gas", but it wasn't so bad to need to run back out. So you do want to consider such, but it's not a panic item. The manual does suggest cracking a window for some ventilation, but others say "That's letting your heat out in freezing conditions and stupid!" So it's up to you to perhaps do some experiments and come to your own conclusions. There's always the thoughts on possible gas leaks to check for before any use, so don't be afraid to do that. If using a hose and refillable tank, here's a simple leak check I do. With everything connected and heater off, open the tank valve watching how the hose "jumps" when getting pressurized, then close the tank valve, wait 1-2 minutes, then open it again watching for another "Jump" in the hose. If it does jump again, that means gas leaked out over the 2 minutes, otherwise no jump means it held pressure. It is against fire codes to have a refillable tank inside (anything except 1 pound tanks), so I think that can give you another purpose in having a window cracked, yet I've seen a video on another heater that uses those big tanks with it shown used in a garage (despite the "Outdoor use only" label showing somewhat contradictory info). So lots to consider in using these including the surface it sits on (they warn "May cause floor fading or vinyl damage").
Question:	What size propane can does the heater use
Answer:	It has places for 2 of the small 1 pound tanks like you find in the camping section of stores like Walmart, Target, etc. You can also get a hose like the F273704 by Mr Heater and go to any bigger tank you want (like the 20 pound BBQ ones, or bigger or smaller). On high this will burn the 2 pounds from small tanks in 3 hours, so running it 12 hours in a good shop will burn near half a 20 pound tank in a day. Many like the bigger tanks for both length it runs and propane can go for $3 a gallon in bigger tanks vs $3 a quart in those disposable tanks.
Question:	Can this heater be used inside a camper
Answer:	Sure it can. I live full time in a 40 foot RV and use a Mr. Heater Big Buddy that is hooked to a external 30lb tank. Then my other main heater is a Olympian Wave 8 that is plumbed into my RV's propane line. It produces no C02 when its in use but it does consume oxygen so as a result your ceiling vent should be cracked open a inch or two. For every pound of propane used there is X amount of ounces of water that is released in the form of water vapor. Having a window ajar releases this out of the camper. You can also get a dehumidifier to deal with that. You will instantly know this if you use this with no windows open ... your windows will be covered in condensation. You might think leaving a window open will let the cold in ... quite the opposite. It creates a convection current that aids in the heating of your camper.

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.
