CONNECTING TO GAS SUPPLY

WARNING: A qualied technician must connect heater to gas supply. Follow all local

codes.

WARNING: This appliance requires a 3/8 in. NPT (National Pipe Thread) inlet connection to

pressure regulator (see Fig. 5).

CAUTION: Never connect heater directly to the gas supply. This heater requires an external

regulator (not supplied). The external regulator between the gas supply and heater must be

installed. Gas supplier provides external regulator for natural gas.

INSTALLATION ITEMS NEEDED

Before installing heater, make sure you have the items listed below.

• piping (check local codes) sealant

• (resistant to propane/LP gas)

• equipment shutoff valve*

• test gauge connection**

• sediment trap

• tee joint

• pipe wrench

• exible gas hose (check local code)

*A CSA design-certied equipment shutoff valve with 1/8 in. NPT tap is an acceptable alternative

to test gauge connection.

**Purchase the optional CSA design certied equipment shutoff valve.

WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly

known as well-head gas.

The installer must supply an external regulator for liquid propane. The external regulator is

provided by the gas supplier for natural gas. The external regulator will reduce incoming gas

pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water column

for propane and between 5 and 10.5 inches of water column for natural gas. If you do not reduce

incoming gas pressure, heater regulator damage could occur. Install external regulator with the

vent pointing down as shown in Fig. 6. Pointing the vent down protects it from freezing rain or

sleet.
