Figure 14 - Gas Connection
INSTALLING GAS PIPING TO FIREPLACE LOCATION
WARNING: A qualifi ed service person must connect
fi replace Insert to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP heater directly
to the propane/LP supply. This heater requires an
external regulator (not supplied). Install the external
regulator between the heater and propane/LP supply.
WARNING: Never connect natural gas fi replace
insert to private (non-utility) gas wells. This gas is
commonly known as wellhead gas.
Installation Items Needed
Before installing fi replace insert, make sure you have the items listed
below.
•
external regulator (supplied by installer)
•
piping (check local codes)
•
sealant (resistant to propane/LP gas)
•
equipment shutoff valve *
•
test gauge connection *
• sediment
trap
• tee
joint
• pipe
wrench
•
approved fl exible gas line with gas connector (if allowed by local
codes) (not provided)
* A equipment shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the optional equipment
shutoff valve from your dealer.
For propane/LP units, installer must supply an external regulator.
External regulator will reduce incoming gas pressure. You must reduce
incoming gas pressure to between 11" and 14" of water. 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 13
. Pointing vent down protects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of 1/2"
diameter or greater to allow proper gas volume to
fi replace insert. If pipe is too small, undue loss of
volume will occur.
Installation must include an equipment shutoff valve and plugged 1/8"
NPT tap. Locate NPT tap within reach for test gauge hook up. NPT
tap must be upstream from fi replace insert
(see
Figure 14
).
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.
Check your building codes for any special requirements for locating
equipment shutoff valve to fi replaces.
Apply pipe joint sealant lightly to male NPT threads. This will prevent
excess sealant from going into pipe. Excess sealant in pipe could
result in clogged fi replace valves.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap in supply line as
shown in
Figure 14
. Locate sediment trap where it is within reach
for cleaning. Install in piping system between fuel supply and heater.
Locate sediment trap where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants. This keeps them
from going into fi replace insert gas controls. If sediment trap is not
installed or is installed wrong, fi replace may not run properly.
