FIREPLACE INSTALLATION
Continued
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 replace (see Figure 31).
IMPORTANT: Install main gas valve (equipment shutoff valve)
in an accessible location. The main gas 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 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 replace valves.
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
We recommend that you install a sediment trap/drip leg in supply
line as shown in Figure 31. Locate sediment trap/drip leg where it
is within reach for cleaning. Install in piping system between fuel
supply and replace. Locate sediment trap/drip leg where trapped
matter is not likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into replace gas con-
trols. If sediment trap/drip leg is not installed or is installed wrong,
replace may not run properly.

Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not provided)
1. Open lower louver door panel by gently pulling forward.
2. Route exible gas line (provided by installer) from equipment
shutoff valve to replace. Route exible gas supply line through
one of the access holes on side of replace.
3. Attach exible gas line from gas supply to control valve (see
Figure 32).
4. Check all gas connections for leaks. See Checking Gas
Connections.

WARNING: Test all gas piping and connections,

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
1. Disconnect replace and its individual equipment shutoff valve
from gas supply piping system. Pressures in excess of 1/2 psig
(3.5 kPa) will damage replace gas regulator.
2. Cap off open end of gas pipe where equipment shutoff valve
was connected.
3. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas replace or opening main
gas valve located on or near gas meter for natural gas replace,
or using compressed air.
4. Check all joints of gas supply piping system. Apply noncor-
rosive leak detection uid to all joints. Bubbles forming show
a leak. Correct all leaks at once.
5. Reconnect replace and equipment shutoff valve to gas supply.
Check reconnected ttings for leaks.
1. Close equipment shutoff valve (see Figure 33).
2. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas replace or opening main
gas valve located on or near gas meter for natural gas replace,
or using compressed air.
