User questions & answers

Question:	How much current does this fan draw
Answer:	Yes
Question:	What are the Watts, warranty, and roof hole size
Answer:	no. this is a partial kit... i recently purchased, needing to rebuild my differentials primairly and anything else in between . only once i tore it all down did i realize there is only enough bearings for 1 differential. plus there are multiple extra tiny bearings that i have never seen on my slash or slash 4x4. my kit said slash 4x4 on it but i dont think it was the right one, if so, this kit is a partial.
Question:	Can I out a rheostat to turn it to half power? It's pretty loud right now and realized my attic isn't that big, (1200 sf
Answer:	No, it is specifically for the slash 4X, Stampede 4x4 and the Telluride 4x4. It is the bearing carrier for the main spur gear assembly. PJs RC
Question:	Can you use a variable speed controller with this fan
Answer:	Have had mine in since early May w/weekly runs on sandy/dirt track w/no problems, better than stock. my guess would be that you may have slipper clutch to tight? I snug mine down and back off 1 full turn. Also make sure your slipper plate is lined up correctly, it can be 1/4 turn off of the correct position and still "look" good, you should not be able to move it even during loose assembly.

User questions & answers

Question:	Can this be mounted on a wall
Answer:	Yes you can, apart from the sunlight angle
Question:	Does it have a screen to keep insects out
Answer:	We do not carry a screen at the moment
Question:	How do I get a/c Add on
Answer:	Please call us for the ac power kit
Question:	How do I calculate the wattage of a solar attic fan
Answer:	Watts are the result of multiplying the operating voltage times the draw max current. (W = E x I). Your operating voltage on an AC fan is 120 volts. The operating current is posted on the manufacturer's label on the fan. Multiply one by the other and you get your watts. On a DC system like solar or batteries the voltage is the max output produced and the current (I) is also on the label.

Broan 358 120V Attic Ventilator, Roof Mounted, Aluminum, 1000 CFM

In summer, attics can reach 150-Degrees Fahrenheit or more, warming living areas, increasing the air-conditioning load, and adding to energy bills. In winter, ice dams can result, and moist air can condense causing mildew, rotting wood and wet insulation. Year-round attic ventilation ensures a cooler, drier attic that can extend roof life by preventing rot, premature aging and shingle distortion. A cooler attic extends the life of an air conditioner and lowers air conditioning expense.

User questions & answers

Question:	What is included
Answer:	Yes, you can raise or lower temp by putting your finger on the screen. You can also say "Alexa raise the temperature ".
Question:	Can it be mounted upside-down
Answer:	Yes it does. It takes the four wires that exist in your wall already and at the air handler, you install the 5 wire to four wire converter and can skip running the fifth “c” wire. It’s very easy. You will love it
Question:	Is the a fabric cover that can be purchased that will fit over it during the winter? If so any recommendations
Answer:	Nope
Question:	How tall is it
Answer:	The Ecobee 4 comes with mounting screws and screw anchors. I've installed three Ecobees in my home and have not needed a special bracket. It also comes with a suitable back plate to cover up any holes left by a bigger thermostat.

User questions & answers

Question:	Why is my fan so noisy
Answer:	120 VOLTS - 8 AMPS
Question:	Is the included thermostat switch at the fan unit or something that can be installed remoted, for adjustments without climbing on a ladder to change
Answer:	960 watts, 1 year limited warranty, roof hole size is 14-3/8" diameter.
Question:	What is the temperature range for the unit, aka what is the lowest temp at which the fan can turn on
Answer:	I think you have one of two choices. Live with it, or install a smaller CFM unit. Personally, I'd learn to live with the noise. You could always add more insulation to the attic...
Question:	Temperature control included
Answer:	The 356BK is not designed to be used with a speed control. By using a speed control the motor will get very hot and will probably burn out prematurely.

User questions & answers

Question:	Can this be roof mounted
Answer:	Ventilator with thermostat
Question:	Does this have a wind rating? Is it safe for areas with hurricanes
Answer:	I have run these upside down on the bench just to test them maybe only 10 to 15 minutes, but they didnt seem to have any issues, of course they would not be weather proof by any means and if the suction was from outdoors dirt and moisture would get pulled into the motor , not good with an open frame motor design. If your intention was to say, pull air from an upstairs room or attic down into a building I see no real issues
Question:	Where is it made
Answer:	I don’t think you need to cover it during the winter decades of the dome
Question:	Does it come with backdraft dampers
Answer:	8" to 10". I did not have to go far down the roof line to hide it from the street in front. If, I get a chance, I will get up there and measure it, as I have something else to do up there.

User questions & answers

Question:	so without the thermostat, does this fan run all the time while it is light out
Answer:	Yes, it runs continuously when it receives light. You may purchase a Broan thermoswitch which will shut it off if the temp is less than 50 deg F (which means it'll basicaly run all the time). I purchased the thermoswitch for the Natural Light brand because it turns on at 80 and off at 70 (added benefit: it's cheaper). For my climate in Los Angeles, that range is preferable (I would think the same in other climates, too). To install, just clip off the black male spade connector of the Broan and replace it with a female and reconnect with the switch in series. The wiring that comes with the switch is not used. It's easy and it works!
Question:	Can this fan sustain hurricane winds
Answer:	Our unit is located on the Ocean and we have had storms but no hurricanes since it was installed.
Question:	Can this be installed on a Terracotta tiled roof
Answer:	Only if the tiles are relatively flat. Broan's website indicates the fan is designed for a "shingled" roof. Not much clearance between the base and the fan housing, but it woks great.
Question:	Will these keep the dampness out of a shed? Shed is only 140 square feet
Answer:	This fan is designed for spaces of 3200 cubic feet. We would not recommend using this fan in a small space. Please contact our Technical Support Department at 800-637-1453 for assistance in determining the best fan for your needs.

User questions & answers

Question:	do you have to oil it
Answer:	Oiling the motor once or twice a year will extend the life of the motor. If the motor requires oiling, oil ports or openings will be located on both motor end plates. Use a SAE 20 non-detergent motor oil.
Question:	Has anyone retrofitted one of these to a roof vent
Answer:	I did one in a gable vent, it comes with nice instructions. I mounted it on a piece of plywood then mounted two 2x4s to the gable vent framing then mounted the plywood to the 2x4. It was easy, my 12 yr old son and I did it in 30 minutes. It was summer time in the attic so we wanted to do it fast. I bought a cheap extension and cut off one end and wired it to the leads then ran it to an outlet in the attic.
Question:	How long is the thermostat wiring. How far will it reach away from the fan
Answer:	Wiring on the fan thermostat is very short about 12" or so. I rewired it and moved the thermostat to a location about 25 feet away. This allows me to set the thermostat without having to crawl down the entire length of the attic.
Question:	The 2500 cfm fan uses less power than the 1500 cfm? and haf of the 1600 cfm? Am I missing something here
Answer:	I had to find this out myself straight from the manufacturer, https://bvc.com/skin/frontend/base/default/salessheets/gable_ss.pdf.

User questions & answers

Question:	Is it thermostatically controlled
Answer:	If you mean is it easy to see the positive & negative wires going directly into the fan, cut & splice your own switch in, bypassing thermostat.... yes it is easy to do.
Question:	is the fan on the roof line or deeper
Answer:	I think sealed, I don't remember any zerk fittings or oil holes to use. Mine has been in my house two years and there are no problems. I by passed the thermocouple and have it on a switch. I put one in my daughters house and used the thermocouple because she and her husband are gone quite a bit and not at home to turn it on. No issues after 18 months. Quiet because I used rubber padding between the fan and board it is connected to. It keep our upstairs a lot cooler. No issues with bearings yet, and I don't really expect any.
Question:	Can this be install to an indoor patio? I have a room where the ceiling is essentially a shingled roof with no insulation or space inbetween
Answer:	The thermostat is inside the fan--look at the picture, it is the little box in the lower left corner where the electrical wire is running into the fan. You can take the thermostat out as it is only attached with a couple of screws. Mounting it a few feet away from the fan is easily doable.
Question:	I just installed this attic fan in my Florida which is in path of hurricane Irma. What should I expect
Answer:	The fan is fairly quiet inside the house compared to others I have installed, however outside at the gable vent you can hear it very well, this fans moves a lot of air,
