Hi, my situation is that I have an existing chimney with the proper current lining, I would like to place the dual-wall furnace next to the chimney, this would make it so that I would come out of the top of the furnace and then have to make a 45-90 degree turn to connect to the chimney. The turn would have to occur as close to the top of the furnace as possible. Is this something that would be possible?
By Collin C. - NFI Master Hearth Professional on February 18, 2014
You can indeed offset the vent piping to route over to the existing chimney. Ideally, a 45 degree offset would be used, as 90 degree offsets can cause drafting problems with natural vent appliances. After the initial oval to round adapter is used, the 45 degree bend can be made to route over to the chimney.

I have a natural gas heater like this can I convert it to burn propane?
By Collin C. - NFI Master Hearth Professional on January 27, 2014
These units are indeed able to be converted between fuels. The exact conversion kit needed differs by the unit, as gas valves have been revised over the years.

I am interested in purchasing one of these wall mount heaters. Does this come with a vent kit as well? And if so, I assume it is B vent, and if it does, what does it come with?
By Tyler M. - NFI Certified Specialist on October 24, 2013
This furnace does not include any venting components; it requires 4" oval type B-1 gas vent pipe. For more information, please see page 6 of the owner's manual.

Although the pilot light always works, the main burners are turning off and on repeatedly when heat is needed. Any ideas on this problem?
By Collin C. - NFI Master Hearth Professional on February 13, 2013
It is possible that the thermocouple is becoming weak and no longer supplying adequate power to the gas valve for the unit to operate continuously. With the unit shut down and cool, the thermocouple can be cleaned by lightly sanding the probe with fine grit sandpaper or Emory cloth.
I also recommend checking incoming and manifold gas pressure at the units gas valve. Fluctuating or out of spec gas pressure can also create this problem.

We are interested in a direct vent propane wall furnace with a blower if possible. One room is 600 sq ft, and has 18' ceilings with an overhead paddle (heat) fan. We would like to use a programmable thermostat since the room is used 1 day a week (garage type room). We were thinking 50,000 BTU's. What are your thoughts?

Does this furnace have to be installed between two rooms? Do I need to get parts in addition to this furnace, like a flue or chimney, to finish setting it up?
By Tyler M. - NFI Certified Specialist on June 7, 2013
Yes, this furnace is meant to be installed in a wall between two rooms only. The venting components for it are sold separately; it requires 4" oval type B gas vent pipe. Please see page 6 of the owner's manual for more information.
