CONNECTING TO GAS SUPPLY
WARNING
: A qualified technician must connect heater to gas supply. Follow all local codes.
WARNING
: This appliance requires a 3/8 in. NPT inlet connection to pressure regulator (see Fig. 10).
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 (Not Supplied)
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
• flexible gas hose (check local code)
A CSA design-certified equipment shutoff valve with 1/8 in. NPT tap is an acceptable alternative to test gauge connection.
Purchase the optional CSA design certified equipment shutoff valve from your dealer.
WARNING
: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead 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. 11. Pointing the vent down protects it from freezing rain or sleet.
