    Can this heater be installed on an inner wall of a third-floor apartment?
    1 Answer
    No. All direct vent heaters such as this must be installed on an exterior wall so that the vent can go straight out the back, and terminate on the exterior wall behind it.

    Will this unit work with battery back up during a power outage? Does it have a fan option that would work with a battery back up?
    1 Answer
    As this model features a millivolt style control valve (standing pilot), it does not require AC power for main burner operation. The optional blower would need to be plugged in, however. So, in the event of a local power outage, any battery backup power would need to be provided directly to the receptacle. No model-specific battery backup is available.

    December 21, 2017
    My wall furnace pilot light keeps going out and I believe that it is due to heavy airflow through the exhaust vent. Is there any way to fix this problem without replacing the exhaust vent?
    1 Answer
    This appliance does not have a restrictor or baffle listed in the literature from the manufacturer. If the termination is in a high wind area, we would advise fabricating a wind guard for your horizontal cap.

    Would you use this in a workshop (saw dust etc.)?
    2 Answers
    You could, the main concern would be dust causing the filter to be changed often, though.

    Excellent heater
    This unit replace an older one of the same model. Heat output on the new one is much greater than the 48 year old one when it was new.

    Replaced a 32 year old DV210 with a new one
    After 32 years of service, my DV210 room heater set off a carbon monoxide detector. Upon inspection, found much rust. There are many upgrades and ventless alternatives now and I looked at many. Just replaced and the swap was a direct replacement fit.
    Self contained Works without power Compact and simple. Vented, for use in a room where the grandkids stay.

    Great product
    This purchase of heater & thermostat replaced the same models in a greenhouse which worked great for 13 years. I replaced the old items with precisely the same models because I was satisfied with them; the replacements suit me fine and were easy to install by my HVAC installer.

    My 2nd Empire wall mounted unit in 20 years and I love it.
    So 20 years ago I did a house renovation and had a 250 sq. foot space that I could not get a heating duct to. I did some research and discovered the Empire 10,000BTU wall mounted heater. It seemed like the best option for the space. It was great. Kept us toasty in the winter.

    The unit had some issues last spring and rather than try to fix it I opted for a new one. I love it. My wife loves it. Good job.

    Quiet Comfort
    This unit warms our 450 sq.ft. mancave unobtrusively. It quickly brings our basement area up to a comfortable temp. It is easy to start and, with a remote thermostat, easy to control.
    Easy to install. The outside vent will make noise when it is hit by rain. The best installation would be under an eave.

    Purchased as a replacement
    Replacement for the original that was approximately 18 years old. The heating chamber rusted through.
    Good service throughout it's life with proper maintenance. Pilot orifice clogs every three to four years and needs replacing. Suggest having a spare on hand.

    Very easy install
    If you can hook up a stove or dryer you can hook up this furnace. Very easy to setup and operate. Very happy with purchase. There is a lot of smoke when if first fires up so be aware that it is normal. If you read the instructions and manual it will state this.
    simple, reliable, easy to install and maintain the connection between the vent and the vent pipes is very snug but that's probably a good thing

    Great heater!
    We have heated a about 800 sq ft two story home in Akaska for more than twenty years with the above heater. I could not be happier with it. We have replaced ONE thurma couple in all the years with NO other problems. No worries about heat durning power outages. It is number 1 on my list of best buys ever. You can not go wrong with an empire gas stove.

    Great Heater but...
    My wife and I both like the heater, seems to be very efficient and she warm on the other side of the room
    easy installation, great heat The unit gets very hot when the front casing is replaced, after installing the optional blower(A MUST HAVE) we ran it without the front casing for a time and it blew heat everywhere however when I replaced the front casing it got hot against the wall. (I think this is due to the heat shield ) Possibly a bad design for the air flow

    This Purchase was Excellent!
    My mother has a small rental cabin on her property and we needed a new heat source for it.
    We were somewhat desperate due to being in the middle of a cold snap.
    While preparing the cabin to rent, we discovered the vent free gas fireplace, was emitting carbon monoxide at dangerous levels. We looked into a vented
    fireplace, but the unit and installation would have cost us $3800.00. Kinda steep for a little cabin Which only provides a modest income . We looked into gas wall furnaces, and found the The salesman we talked to was VERY knowledgeable about MANY types of heating sources. He really helped us find just the right size, type to suit our needs. We were able to get a natural gas console wall heater perfectly suited for the cabin at a much lower cost!
    Good quality for the cost. Can be used as a heat source WITHOUT ELECTRICITY! Easy to operate. Easily heats the whole cabin. Nothing against this unit. Possibly only that a fireplace with visible fire would we more visibly attractive.

    Excellent heat source !
    I used this for one winter a few years back to heat my new 1200 square foot home because I did not yet have my permanent radiant heating system completed. I did buy the fan kit later as well which is definitely needed if you plan to heat more than a single room. Worked great with no issues and kept the whole house warm and toasty. Used 600 gallons of propane that winter, same as my radiant system in later years. I'd recommend this heater to anyone...
    None I can think of.

    Ten Years Old
    I installed this unit in a 77-year-old cabin high in the Santa Cruz mountains. After using it for nearly ten years, it still does a great job of producing heat. It has developed a bang when it starts and stops, but it may be a problem with the heat chamber, which is covered by a ten year warranty.

    Supremely Happy

    Top Too Hot
    Because of the position of the blower, the heat cause the top of the unit to get very hot. It would be better if the blower were on the top part of the unit and directed the heat down toward the bottom.

    Supplemental Room Heat
    This unit was purchased for a rental property. Since it was installed very recently, I am unsure how it will affect the gas bill as of yet. I believe, however, that the thermostat is defective since the heater will not cycle on and off.

    Broken Thermo Coupler
    I used this heater for five years without any problems and was very happy with it. Last year, I had to replace the thermocoupler. Now, at the start of another winter, it appears that the thermocoupler is again broken. Unfortunately, it is not a cheap part since the unit uses the more expensive wired coupler instead of the tube version.

    No Need to Burn Fuel
    Our little heater, though not very attractive, keeps us from having to burn fuel in our vacation cabin. It keeps the pipes from freezing at 45 degrees on low, which is a better track record than other heaters which keep pipes from freezing at 60 degrees. We can use ours to dry wet clothes by placing them in front of the blower. Our children enjoy curling up underneath the heater to sleep.
