INSTALLATION
CONNECTING TO GAS SUPPLY
WARNING: A qualified service technician must connect the gas fireplace insert to the gas supply.
Follow all local codes.
CAUTION: Never connect the gas fireplace insert directly to the gas supply. This gas fireplace
insert requires an external regulator (not supplied). The external regulator between the gas
supply and the gas fireplace insert must be installed. The gas supplier provides the external
regulator for natural gas.
WARNING: Never connect the gas fireplace insert to private (non-utility) gas wells. This gas is
commonly known as wellhead gas. 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 6 and 14 in. of water column for natural gas. If you do not reduce
incoming gas pressure, heater regulator damage could occur. Install the external regulator with
the vent pointing down as shown in Fig. 15. Pointing the vent down protects it from freezing rain
or sleet.
* Purchase the optional equipment shutoff valve from your local Home Center store.
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 ½ in. diameter
or greater to allow proper volume gas to heater. If pipe is too small, loss of pressure
will occur. Installation must include an equipment shutoff valve, union, and plugged
1/8-in. NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must
be upstream from heater (See Fig. 15).
IMPORTANT: Install 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.
