If pipe is too small, undue loss of volume will occur. Installation must include an equipment shutoff valve, union andplugged 1/8" NPT tap. Locate NPT tap within reach for test gaugehook 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 controls. 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 nut-driver • 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. To Gas Supply (Natural) To External Regulator (Propane/LP) Flexible Gas Line Do NOT Kink Equipment Shutoff Valve Control Valve Figure 32 - Connecting Flexible Gas Line to Millivolt Valve 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. 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. 2. Cap off open end of gas pipe where equipment shutoff valve was connected. 3. Pressurize supply piping system by either opening propane/LPsupply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fireplace or using compressed air. 4. Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once. 116192-01B 20 FIREPLACE INSTALLATION Checking Gas Connections (Cont.) Installing Optional Wall Mount Switch - GWMS2 FIREPLACE INSTALLATION Continued 5. Reconnect fireplace and equipment shutoff valve to gas supply. Check reconnected fittings for leaks. Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa) 1. Close equipment shutoff valve (see Figure 33). 2. Pressurize supply piping system by either opening propane/LPsupply tank valve for propane/LP gas fireplace or opening main gas valve located on or near gas meter for natural gas fireplace or using compressed air. 3. Check all joints from propane/LP supply tank or gas meterto equipment shutoff valve (see Figure 34, for propane/LP orFigure 35, for natural gas). Apply noncorrosive leak detectionfluid to all joints. Bubbles forming show a leak. Correct allleaks at once.
