CONNECTING TO GAS SUPPLY

WARNING: A qualified service person must connect heater to gas supply. Follow all local codes.

CAUTION: Never connect heater directly to the gas supply. This heater requires an external regulator (not supplied). lnstall the external regulator between the heater and gas supply.

INSTALLATION ITEMS NEEDED

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

piping (check local codes)

sealant (resistant to natural or propane/ LP gas)

equipment shutoff valve* test gauge connection* sediment trap

see joint pipe wrench

flexible gas hose (check local codes).

*A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-

certified equipment shutoff valve from your dealer. See Accessories, page 16.

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