Open lower louver door panel by gently pulling forward.2. Route flexible gas line (provided by installer) from equipmentshutoff valve to fireplace. Route flexible gas supply line throughone of the access holes on side of fireplace.3. Attach flexible gas line from gas supply to control valve (seeFigure 32).4. Check all gas connections for leaks. See Checking GasConnections.FIREPLACE INSTALLATIONConnecting Fireplace To Gas SupplyChecking Gas ConnectionsFigure 32 - Attaching Flexible Gas Line to Control ValveFlexible Gas LineDo NOT KinkEquipmentShutoff ValveTo Gas Supply(Natural)To ExternalRegulator(Propane/LP)ControlValvePressure Testing Gas Supply Piping SystemTest Pressures In Excess Of 1/2 PSIG (3.5 kPa)1. Disconnect fireplace and its individual equipment shutoff valvefrom 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 valvewas connected.3. Pressurize supply piping system by either opening propane/LPsupply tank valve for propane/LP gas fireplace or opening maingas valve located on or near gas meter for natural gas fireplace,or using compressed air.CHECKING GAS CONNECTIONSWARNING: Test all gas piping and connectionsfor leaks after installing or servicing. Correct allleaks at once.WARNING: Never use an open flame to check fora leak. Apply a noncorrosive leak detection fluid to alljoints. Bubbles forming show a leak. Correct all leaksat once.4. Check all joints of gas supply piping system. Apply noncorro-sive leak detection fluid to all joints. Bubbles forming show aleak. Correct all leaks at once.5. Reconnect fireplace and equipment shutoff valve to gas sup-ply. 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 maingas valve located on or near gas meter for natural gas fire-place, or using compressed air.3. Check all joints from propane/LP supply tank or gas meter toequipment shutoff valve (see Figure 34 for propane/LP orFigure 35 for natural gas). Apply noncorrosive leak detec-tion fluid to all joints. Bubbles forming show a leak. Correctall leaks at once.Figure 33 - Equipment Shutoff ValveClosedEquipmentShutoffValveFigure 35 - Checking Gas Joints for Natural Gas FireplaceFigure 34 - Checking Gas Joints for Propane/LP Gas FireplacePropane/LPSupply TankGas ValveEquipmentShutoffValveGasMeterGas ValveEquipmentShutoffValve
