Check all joints from gas meter to equipment shutoff valve fornatural gas or propane/LP supply to equipment shutoff valvefor propane/LP (see Figures 24 or 25). Apply noncorrosiveleak detection fluid to all joints. Bubbles forming show a leak.4. Correct all leaks at once.Pressure Testing Fireplace Gas Connections1. Open equipment shutoff valve (see Figure 23).2. Open main gas valve located on or near gas meter for naturalgas or open propane/LP supply tank valve.3. Make sure control knob of fireplace is in the OFF position.4. Check all joints from equipment shutoff valve to gas regulator(Thermostat-Controlled Models), or to gas control valve (Remote-Ready Models) (see Figures 24 or 25). Apply noncorrosive leakdetection fluid to all joints. Bubbles forming show a leak.5. Correct all leaks at once.6. Light fireplace (see Operating Fireplace, pages 19 through 23).Check all other internal joints for leaks.7. Turn off fireplace (see To Turn Off Gas to Appliance, page 20for Thermostat-Controlled Models or page 22 for Remote-Ready Models).Gas Regulator orGas Control ValveGas Regulator orGas Control ValveINSTALLATIONContinuedINSTALLATIONChecking Gas ConnectionsWARNING: Test all gas piping and connections,internal and external to unit, for leaks after installingor servicing. Correct all leaks at once.WARNING: Never use an open flame to check fora leak. Apply a noncorrosive leak detection fluid toall joints. Bubbles forming show a leak. Correct allleaks at once.CAUTION: Make sure external regulator has beeninstalled between propane/LP supply and fireplace.See guidelines underConnecting to Gas Supply,pages 14 and 15.Pressure Testing Gas Supply Piping systemTest Pressures In Excess Of 1/2 PSIG (3.5 kPa)1. Disconnect appliance with its appliance main gas valve (controlvalve) and equipment shutoff valve from gas supply piping sys-tem. Pressures in excess of 1/2 psig will damage heater regulator.2. Cap off open end of gas pipe where equipment shutoff valvewas connected.3. Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gasvalve located on or near gas meter for natural gas, or usingcompressed air.4. Check all joints of gas supply piping system. Apply noncorrosiveleak detection fluid to all joints. Bubbles forming show a leak.5. Correct all leaks at once.6. 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 23).2. Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gasvalve located on or near gas meter for natural gas, or usingcompressed air.CHECKING GAS CONNECTIONSFigure 23 - Equipment Shutoff ValveONPOSITIONOFFPOSITIONOpenClosedEquipmentShutoff Valve
