Propane Fireplaces - Propane Gas Fireplaces

It is not recommended that a tank smaller than 100 pounds be used for a propane fuel fireplace. 

For your sizing, I would suggest a vent free fireplace upwards of 35,000 BTU's.

While you would need about 23,800 BTU to adequately heat the space and none of the gas hearth systems we offer should be used as a substitute for your home's central heating, the Napoleon WHVF31 Plasmafire Wall-Mounted Vent-Free Gas Fireplace would come very close to the BTU rating needed at 20,000 BTU/hr.

That depends on whether the unit is a Direct Vent, a B Vent or Vent free.

While this information is not normally specified in the product literature for most gas fireplaces, the mantel clearances that are provided should be used as a reference.

With proper installation, propane is no different than natural gas with regards to safety when operating a hearth appliance. Propane gas is heavier than natural gas, so match lit systems without a safety pilot would not be available with liquid propane as they are with natural gas. With all propane systems, pilot flame loss will result in gas flow being shut off through the valve. The safety concerns would be the same with either fuel type, but are eliminated with proper installation and maintenance.
