Connecting To Gas Supply; Installation Items Needed - HearthSense ANI Manual

CONNECTING TO GAS SUPPLY

WARNING:
A qualified technician 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). The external regulator between the gas supply and heater must be installed.

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
·
flexible gas (check local code)
* A CSA design-certified equipment shutoff valve with 1/8-inch 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. 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 Figure 12. Pointing the
vent down protects it from freezing rain or sleet (see Figure 13).
