I'm wondering if this furnace comes with a thermostat
and a blower? How does it circulate the heat and how does one control
By Customer Service on October 17, 2011
Answer:The blower and thermostat are not included with this furnace. You may select them from the Accessories tab on this unit's item page. Without these items, the unit would heat your room/home via radiant heating and would be controlled manually.

I wondered if you could tell me the AFUE rating of the Empire GWT35 Gravity-Vented Wall Furnace. Thank you.
By Brennan W. on January 25, 2017
Answer:Per the manufacturer, the AFUE on this heater is 70%.

Will the Empire GWT35 heat a 800 sq ft area in an extremely cold climate with no other heat source? If the heater is running "heavy" in high mode, can you estimate at how many gallons of propane this would use in a 24 hr. period?
By Tyler M. - NFI Certified Specialist on June 18, 2013
Yes, this GWT35 is capable of heating 800 square feet, particularly if your cabin is well insulated and does not have tall/cathedral ceilings. We recommend adding the Empire GWTB2 Automatic Gas Furnace Blower
to increase the efficiency of this model. The 35,000 BTU output will consume approximately 40 lbs of propane in a 24-hour span.

What is the BTU input and output of this furnace?
By eFireplaceStore on October 29, 2014
Answer:The input rating for this model is 35,000 BTUs and the output rating is 24,500. This is sufficient to heat 700 square feet on average. Using the accessory blower will increase the overall thermal efficiency of the unit and will heat the space more quickly.

How do you light this heater?
By Collin C. on November 3, 2011
Answer:This unit has a standing pilot that must be lit like most gas water heaters or furnaces. You will need to access the gas valve on the heater and switch the control knob to pilot. You will then need to use a match or lighter to light the pilot while pushing the pilot knob in on the gas valve. Once a flame is present, the pilot knob will need to be held for 1 minute to establish a good flame. The knob will then be released and the unit can be switched on. You will only need to do this at the beginning of the heating season. The pilot will remain lit throughout the season and can be shut down when the unit will not be needed during warmer weather.

Is this "ready" for the wireless remote that is sold optionally? If the power goes off, does the thermostat still work, or do you control the unit manually? Is the optional fan, "sensor" controlled, or manually operated?

Can this Empire GWT35 gravity-vented wall furnace be used in a bathroom or bedroom?
By eFireplaceStore on November 23, 2015
Answer:While the manufacturer does not specifically state against installing this heater in a bedroom or bathroom, it is not recommended due to the combustion air requirements of the unit. Only a direct vent appliance or a vent free with an input of less than 10k for a bedroom or 6k for a bathroom should be used.

What does gravity vented mean?
By Collin C. - NFI Master Hearth Professional on October 4, 2013
Answer:During operation of a gravity type furnace, all the heat that is generated rises from the top registers to heat the room. The rising heat forces cold air to the floor, where it is drawn into the furnace and heated. This creates a sort of natural convection. The process can be assisted by installing an optional circulating blower.

I'm interested in this furnace for a replacement for my cabin but would like a brown front, not white. Does it come in any other colors than white?
on November 9, 2012
Answer:This gravity-vented wall furnace is only available in white, as pictured. We apologize for the inconvenience. Please let us know if you have any additional questions.

When the pilot is lit on my stove, it is loud and seems to be burning way too high. This heater was just cleaned thoroughly and installed a day ago. I also have a new gas line coming into the house to the heater. It is so loud and burning so high that I am afraid to leave it on.
The heater is hooked up to a thermostat and seems to work outstanding when it comes on. It just seems like the pilot at this point could heat the house on its own. Any recommendations for how to turn it down and have it still stay lit, or any ideas if something else could be wrong?
By Collin C. - NFI Master Hearth Professional on December 3, 2012
Answer:It does sound as if the pilot flame is adjusted too high. There is a pilot adjustment screw on the gas valve, which will be labeled as such. It may also simply say "pilot." The screw can be adjusted clockwise to reduce the flame size.
The flame should be just large enough to engulf the thermopile. It should not extend past the thermopile by more than 1/2 of an inch or so. Reducing the pilot size should help to eliminate the roar and oversize flame you now have.
