CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified ser-
vice person must connect
heater to gas supply. Follow all
local codes.
CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. Propane/LP
heaters require an external regu-
lator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
WARNING: For natural gas
units, never connect heater to
private (non-utility) gas wells.
This gas is commonly known as
wellhead gas.
