Never use sealant on flare threads.WARNING: Use pipe joint sealant that is resistantto liquid petroleum (LP) gas.We recommend that you install a sediment trap in supply line asshown in Figure 22. Locate sediment trap where it is within reach forcleaning. Install in piping system between fuel supply and fireplace.Locate sediment trap where trapped matter is not likely to freeze. Asediment trap traps moisture and contaminants. This keeps themfrom going into fireplace gas controls. If sediment trap is notinstalled or is installed wrong, fireplace may not run properly.CAUTION: Use only new, black iron or steel pipe.Internally-tinned copper tubing may be used in cer-tain areas. Check your local codes. Use pipe of 1/2"diameter or greater to allow proper gas volume tofireplace. If pipe is too small, undue loss of volumewill occur.Figure 21 - External Regulator on Propane/LP Supply Tank withVent Pointing DownExternalRegulatorVentPointingDownPropane/LPSupply TankINSTALLATIONContinuedFigure 22 - Gas Connection* Purchase the optional CSA design-certified equipment shutoffvalve from your dealer.
