INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes.
IMPORTANT: This appliance requires a 3/8-inch NPT (National Pipe Thread) inlet connection to the
pressure regulator. Never connect the heater to private (non-utility) gas wells, commonly known as
wellhead gas.
WARNING: Do not overtighten gas connections.
CAUTION: Use only new, black iron or steel pipe. Internally tinned copper tubing may be used in certain
areas. 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.
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure must
be a minimum 6'' WC for NG & 11" WC for LP with a max pressure of 14'' WC for NG & 14" WC for LP.
If gas line pressure is higher, the unit will not work and heater regulator damage could occur.
CAUTION: Never connect heater directly to an LP 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).
Typical Inlet Pipe Diameters
Use 3/8-inch black iron pipe or greater. Installation must include an equipment shutoff valve, union, and
plugged 1/8-inch NPT tap.
Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Fig. 20).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going
into pipe. Excess sealant in pipe could result in clogged heater valves.
