I have this space heater and it keeps making loud metallic sounds. I have had the gas company out three times to check it. It's scaring me to death! What can it be?
By Collin C. - NFI Master Hearth Professional on December 2, 2011
Answer:The sound you are hearing is commonly called "oil canning". If the unit is fairly new, this can occur for the first several times the unit is burned. It is important to burn the unit for at least one hour on maximum temperature settings when new, to allow the heater components to shape and conform.
If this has never been done, you will need to try this to see if the problem is alleviated. If this continues to happen, there may be an improperly installed shield or panel that is expanding and making the noise. This can usually be adjusted to relieve the pressure and fix the noise.

I like my DV35. However, I am having a problem with the thermostat. There is a 10 to 12 degree variance. If set the thermostat at 60 degrees it will shut off at 72 or 74 degrees. I removed the thermostat from the heater and mounted it to the wall (3 feet from the unit) but it did not make a difference, so I moved it on the wall across from the unit and it still does the same thing. I do have the blower unit installed, is there an adjustment on the thermostat?
By Will M. on December 20, 2016
Answer:I recommend contacting your dealer for technical support and to assist with any potential warranty claims. If the thermostat is heating the room well beyond the set temperature, I recommend contacting your dealer with this part number to pursue warranty replacement or simply purchasing a new thermostat.

My customer's pilot light was blowing out, or being blown out during initial burner ignition. I cleaned the orifice, and the unit runs fine. However, the customer claims that the direct vent exhaust is much hotter than before, and he's had the DV35 for almost 25 years. I explained that the exhaust needs to be hot, and that it's about a 70% efficient unit. He thinks there's more heat going outside through the vent than coming indoors, although there's definitely heat to the indoors also. Could he be accurate with his assessment? If so, is there a satisfactory adjustment that could be made? I made no adjustments to the main burner, only the pilot fuel adjustment .
By Collin C. - NFI Master Hearth Professional on November 20, 2013
Answer:Just to clarify, did you clean both the pilot orifice and main burner orifice? I could definitely see a dirty burner orifice causing a lower output, which would yield lower vent temperatures. If the unit is now operating closer to designed efficiency, the flue temperatures would indeed increase. There is no adjustment or change that could be made that would significantly lower the efficiency of the unit and cause flue gas temperatures to spike. As you mentioned, the efficiency of this unit is lower than what is available on the market now and flue gas temperatures will be hotter. Unless the unit seems to be running more often or appears to have a significant decrease in heating ability, I cannot see an issue.

I cannot get the pilot light of my Empire DV35SG direct vent gas wall furnace to lite. There is a draft that is coming through the pilot light opening and the vent is working right so I'm not sure what could be wrong. How do I troubleshoot this?
By Will M. on October 19, 2015
Answer:This is typical while trying to light a pilot on an appliance that has been turned off in the warmer months. The draft coming through the pilot may actually be air in the gas line and this will need to be bled out for the pilot to light.
This could also be due to certain wind conditions blowing the match out when you are attempting to light the pilot. You should thrust the match through the lighter port right after it flares to ignite the pilot or open a window to eliminate the draft issue and attempt to light the pilot afterwards.

Where does the blower mount on this Empire DV35SG direct vent wall furnace?
By Will M. on November 2, 2015
Answer:When facing the appliance, the blower is mounted into the left section of the casing, adjacent to the combustion chamber.
By James B. from Erin,Tn on December 7, 2016
Answer:Yes, it mounts in the upper left hand corner. See the little cut out at the top? That's where it goes. If you have a drill with a long extension, you can use any small screw.

I have a 3 room that is 23x23 feet, first floor apartment. Will 35k BTUs be enough? I have the clearance room side to side and top to bottom, however I was told the thru-vent on the outside wall has to be a certain distance from the window. Could you tell me the distance? I live in Massachusetts. Also, does this unit have a pilot light, or is it electronic?
By Collin C. - NFI Master Hearth Professional on September 4, 2013
This particular heater would have ample capacity for your heating needs. In fact, the Empire DV25SG Direct Vent Gas Wall Furnace - Propane - DV-25-SGLP
would likely be a better fit, as the capacity is not so far above your needs. Using the DV35SG will likely cause short operation cycles and a stuffy area around the heater.
Clearances of the vent cap to any door or window is specified to be 9 inches for this model. This unit uses a standing pilot for ignition.

Several times per winter the pilot light blows out. We have had a gas technician check the heater and no problems were found. Any suggestions?
By Collin C. - NFI Master Hearth Professional on January 23, 2013
Answer:The issue you are experiencing is likely wind related, as opposed to an issue with the actual pilot assembly. Have you noticed whether or not the problem occurs during breezy or inclement weather? If so, it is likely that a strong enough draft is causing the pilot to extinguish. The only good way to solve this issue is to construct a shroud around the vent termination that would block some of the wind.
If the pilot does not appear to go out under any certain conditions, the other issue may be with delayed ignition. If the main burner ignition is delayed for a couple of seconds, the sudden pressure change that occurs when the burner lights can cause the pilot to blow out. This issue could be attributed to a dirty burner orifice, improper gas pressure, or the air shutter being out of adjustment.

When this Empire fan comes on in my fireplace, it makes a buzzing sound on my TV and causes the picture to have static. How do I fix this?
By eFireplaceStore on March 7, 2016
Answer:Unfortunately, your television is experiencing interference created by the nearly electric motor in the fan. All electric motors emit a certain level of RF "noise" when operating and electronics are tested to be able to withstand this interference by use of internal shielding. If the shielding has failed for any reason, you will experience the symptoms you describe. You will need to double check all connections to the television and any other devices it is linked to. Any loose connections, damaged cables, or other issues could cause the problem. You can temporarily unplug any DVD, Blu-Ray, or audio equipment to test if they may be back feeding the noise to the television as well.

How many cubic feet will this Empire DV35SG direct vent gas wall furnace heat? Our area is 20 x 19 feet with 16 foot high ceilings.
By Tyler M. on October 9, 2015
This heater can effectively heat about 700 square feet with standard 8-9 foot ceilings and good insulation, and even with your higher ceiling height it should be sufficient for the area. We recommend adding the optional Empire DRB-1 Automatic Blower
By Todd from Hershey, PA on March 21, 2015
My house has a wall thickness of 13 1/2'' with a brick exterior. Do I need the flue extension kit for this direct vent furnace or can I make the installation without it?
By eFireplaceStore on March 23, 2015
Answer:Unfortunately, the wall thickness is just past the maximum distance that the standard kit is able to traverse on its own. The tubes will technically overlap, but the amount of overlap will be decreased below a safe amount, potentially allowing flue gases to leak. As such, the extension kit should be used.
By michael dow from Ellsworth, Maine on December 31, 2012
My heater's pilot light has blown out twice in eight years. Is there a shield I can buy for it, or do you suggest making one?
By Tyler M. - Fireplace Specialist on December 31, 2012
Answer:It is unlikely that such a shield exists for your furnace, and two outages in eight years does not seem excessive enough to have one fabricated. You can certainly try to identify the issue and remedy it with some kind of homemade shield, but we do not feel this is necessary.
