No vent-free units can be converted from LP or Natural Gas. Some vented units can be converted. Consult your dealer. Empire has kits for those units that can be converted. What size heater do I need to heat my room? There are many variables in determining the correct amount of heat. You should consult your local dealer/installer who can, firsthand, see the space to be heated and determine a size based on the type of construction, floor plan, and climate.
