Questions and answers

How large a space will 125,000 BTU heat?
Master rates it for up to 3,125 sq ft, which suits open job sites, warehouses and tents. Real coverage depends on outdoor temperature, insulation and ceiling height.

It is listed for outdoor and commercial use. Propane forced-air heaters produce exhaust, so any enclosed space needs strong ventilation and a carbon monoxide alarm.
