Correct all leaks at once.WARNING ICON G 001WARNINGNever use an open flame to check for a leak. Apply a mixture ofliquid soap and water to all joints. Bubbles forming show a leak.Correct all leaks at once.16Pressure Testing Gas Supply Piping SystemTest Pressures In Excess Of 1/2 PSIG1. Disconnect heater and its individual manual shutoff valve from gas supplypiping system. Pressures in excess of 1/2 psig will damage heater regulator.2. Cap off open end of gas pipe where manual shutoff valve was connected.3. Pressurize supply piping system by either using compressed air or openingmain gas valve located on or near gas meter.4. Check all joints of gas supply piping system. Apply mixture of liquid soap andwater to gas joints. Bubbles forming show a leak.5. Correct all leaks at once.6. Reconnect heater and manual shutoff valve to gas supply. Check reconnectedfittings for leaks.104024
INSTALLINGContinuedTest Pressures Equal To or Less Than 1/2 PSIG1. Close manual shutoff valve (see Figure 19).2. Pressurize supply piping system by either using compressed air or openingmain gas valve located on or near gas meter.3. Check all joints from gas meter to manual shutoff valve (see Figure 20). Applymixture of liquid soap and water to gas joints. Bubbles forming show a leak.4. Correct all leaks at once.Pressure Testing Heater Gas Connections1. Open manual shutoff valve (see Figure 19).2. Open main gas valve located on or near gas meter.3. Make sure control knob of heater is in the OFF position.4. Check all joints from manual shutoff valve to control valve (see Figure 20). Applymixture of liquid soap and water to gas joints. Bubbles forming show a leak.5. Correct all leaks at once.6. Light heater (see Operating Heater, pages 18 through 20). Check all otherinternal joints for leaks.7. Turn off heater (see To Turn Off Gas to Appliance, page 20).OpenONPOSITIONManualShutoffValveOFFPOSITIONClosedFigure 19 - Manual Shutoff ValveManualShutoffValveControl Valve LocationGas MeterFigure 20 - Checking Gas Joints10402417
