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 fire-place, or using compressed air.4. Check all joints of gas supply piping system. Apply noncorro-sive leak detection fluid to all joints. Bubbles forming show aleak. Correct all leaks at once.5. Reconnect fireplace and equipment shutoff valve to gas sup-ply. Check reconnected fittings for leaks.CHECKING GAS CONNECTIONSWARNING: Test all gas piping and connectionsfor leaks after installing or servicing. Correct all leaksat once.WARNING: Never use an open flame to check fora leak. Apply noncorrosive leak detection fluid to alljoints. Bubbles forming show a leak. Correct all leaksat once.FIREPLACE INSTALLATIONContinuedWe recommend that you install a sediment trap/drip leg in supplyline as shown in Figure 31. Locate sediment trap/drip leg where itis within reach for cleaning. Install in piping system between fuelsupply and fireplace. Locate sediment trap/drip leg where trappedmatter is not likely to freeze. A sediment trap traps moisture andcontaminants. This keeps them from going into fireplace gas con-trols. If sediment trap/drip leg is not installed or is installed wrong,fireplace may not run properly.FIREPLACE INSTALLATIONInstalling Gas Piping to Fireplace Location (Cont.)Connecting Fireplace to Gas SupplyChecking Gas ConnectionsFigure 31 - Gas ConnectionCSA Design-CertifiedEquipment Shutoff Valvewith 1/8" NPT Tap*3" MinimumApproved FlexibleGas LineCap Pipe Nipple Tee JointSediment Trap/Drip LegNatural - FromGas Meter (5.5"W.C. to 10.5"W.C.

Open lower louver door panel by gently pulling forward.2. Route flexible gas line (provided by installer) from equipmentshutoff valve to fireplace. Route flexible gas supply line throughone of the access holes on side of fireplace.3. Attach flexible gas line from gas supply to control valve (seeFigure 32).4. Check all gas connections for leaks.
