FIREPLACE INSTALLATION
Continued
CAUTION: Use only new, black iron or steel pipe.
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 fireplace (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 fireplaces.
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 fireplace 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 fireplace. 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 fireplace gas con- trols. If sediment trap/drip leg is not installed or is installed wrong, fireplace may not run properly.

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

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.

Propane/LP From External Regulator (11" W.C. to 14" W.C. Pressure)
WARNING: Never use an open flame to check for a leak. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. Disconnect fireplace and its individual equipment shutoff valve |
from gas supply piping system. Pressures in excess of 1/2 psig |
(3.5 kPa) will damage fireplace gas regulator. |
Cap Pipe Nipple Tee Joint
2. Cap off open end of gas pipe where equipment shutoff valve |
was connected. |
