Correct all leaks atonce.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.PRESSURE 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.4. Check all joints of gas supply piping system. Apply noncor-rosive leak detection fluid to all joints. Bubbles forming showa leak. Correct all leaks at once.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 maingas 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.
