Determine which side the gas line will be coming into the fireplace.NOTICE: Triple-burner models CBL18/24 or BFLT18/24come preassembled with gas inlet on right side ofburner pan. DO NOT attempt to reposition burner ontriple-burner models. If your fireplace supply is on theleft side, a longer 3/8" flex line should be purchased androuted behind burner pan and away from flame area.2. Using a hammer and screw driver, remove knockout plug fromthe side of the pan that corresponds to the gas line (see Figure 6).3. Unscrew burner inlet fitting from burner manifold.4. Place burner manifold in pan with threaded opening facingopen knockout plug.5. Using thread sealant (resistant to the action of propane/LPgas) on larger end of fitting, screw the burner inlet fittingthrough hole and into burner manifold (see Figure 6). Tightenusing a wrench. If using propane/LP gas, see Propane/LPGas Conversion, page 8.WARNING: 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.CHECKING GAS CONNECTIONSPressure Testing Gas Supply Piping SystemTest Pressures In Excess Of 1/2 PSIG (3.5 kPa)1. Disconnect log set and its individual equipment shutoff valvefrom gas supply piping system.2. Cap off open end of gas pipe where equipment shutoff valvewas connected.3. Pressurize supply piping system by either using compressedair or opening main gas valve located on or near gas meter.4. Check all joints of gas supply piping system. Apply noncorrosiveleak detection fluid to gas joints. Bubbles forming show a leak.5. Correct all leaks at once.6. Reconnect log set 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 5).2. Pressurize supply piping system by either using compressedair or opening main gas valve located on or near gas meter.3. Check all joints from gas meter to equipment shutoff valve(see Figure 5). Apply noncorrosive leak detection fluid to gasjoints. Bubbles forming show a leak.4.
