Gas type and ignition
Gas valves and pilots are made for one gas: order natural gas or liquid propane to match your heater. Millivolt (standing pilot) heaters use different valves from electronic ignition models.
Indoor venting
Vent adapters are listed for positive or negative pressure venting and 6 or 8 inch pipe. Indoor venting and all gas work should be done by a licensed gas technician to local codes.
