Check your building codes for any special requirements for locating manual shutoff valve to fireplaces. Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves. We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 35. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and heater. 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. 1/8" NPT Tap* Approved Flexible Gas Line 3" Minimum Cap Pipe Nipple Sediment Trap/Drip Leg Figure 35 - Gas Connection * The A.G.A. design-certified manual shutoff valve may be supplied with the appliance or you can purchase it from your retailer.

Pressure) Tee Joint 18 104605 OWNER’S MANUAL FIREPLACE INSTALLATION Continued 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 manual shutoff valve to fireplace. Route flexible gas supply line through one of the access holes on side of fireplace. 3. Attach a 45° flare union gas connector to flexible gas line from gas supply (see Figure 36). Connect flare union to flexible gas line attached to gas regulator of fireplace (see Figure 36). 4. Check all gas connections for leaks. See Checking Gas Connections. To Fireplace Gas Valve Flare Union Flexible Gas Line from Fireplace Gas Valve Provided with Fireplace Flexible Gas Line from Manual Shutoff Valve Provided by Installer Manual Shutoff Valve 3. Pressurize supply piping system by either opening propane/LP supply 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 commercial leak test solution to all gas joints. Bubbles forming show a leak. Correct all leaks at once. 5. Reconnect fireplace and manual shutoff valve to gas supply. Check reconnected fittings for leaks. CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply commercial leak test solution to all gas 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 manual 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 manual shutoff valve was connected.

Close manual shutoff valve (see Figure 37). 2. Pressurize supply piping system by either opening propane/LP supply 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 meter to manual shutoff valve (see Figure 38 for propane/LP or Figure 39 for natural). Apply commercial leak test solution to all gas joints. Bubbles forming show a leak. Correct all leaks at once. Pressure Testing Fireplace Gas Connections 1. Open manual shutoff valve (see Figure 37). 2. Open propane/LP supply tank valve for propane/LP fireplace or main gas valve located on or near gas meter for natural gas fireplace. 3. Make sure control knob of fireplace is in the OFF position. 4. Check all joints from manual shutoff valve to thermostat gas valve (see Figure 38 for propane/LP or Figure 39 for natural). Apply commercial leak test solution to all gas joints. Bubbles forming show a leak. Correct all leaks at once. 5. Light fireplace (see Operating Fireplace, pages 25 through 27). Check all other internal joints for leaks. 6. Turn off fireplace (see To Turn Off Gas to Appliance, page 25).
