CONNECTING TO GAS SUPPLY
WARNING: A qualied service person must connect heater
to gas supply. Follow all local
codes.
WARNING: Never connect
natural gas replace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing log set, make sure you have the
items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve*
• test gauge connection*
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certied equipment shutoff valve
with 1/8" NPT tap is an acceptable alternative to
test gauge connection. Purchase the optional CSA
design-certied equipment shutoff valve from your
dealer. See Accessories, page 15.
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 1/2" diameter
or greater to allow proper gas volume to heater. If pipe is too small,
undue loss of volume will occur.
Installation must include an equipment shutoff
valve, union and plugged 1/8" NPT tap. Locate NPT
tap within reach for test gauge hook up. NPT tap
must be upstream from log set (see Figure 4).
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 NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged heater 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 4. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and appliance.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into
heater controls. If sediment trap is not installed or
is installed wrong, heater may not run properly.
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting it
to gas piping and/or ttings.
