INSTALLATION

CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the pressure
regulator.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.
WARNING: Do not over tighten gas connections.
CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain ar-
eas. Check your local codes. Use pipe of 1/2-in. diameter or greater to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.
NATURAL GAS MODELS:
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must be
no greater than 10.5 inches of water. If gas line pressure is higher, heater regulator damage could occur.
PROPANE MODELS:
CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not
supplied). Install the external regulator between the heater and gas supply.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas piping
and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
