Correct all leaksat once.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.Figure 14 - Equipment Shutoff ValveEquipmentShutoff ValveOpenClosedFigure 13 - Gas Connection* A CSA design-certified equipment shutoff valve with 1/8" NPTtap is an acceptable alternative to test gauge connection. Purchasethe optional CSA design-certified equipment shutoff valve fromyour dealer. See Accessory, page 30.We recommend that you install sediment trap in supply line asshown in Figure 13. Locate sediment trap where it is within reach forcleaning. Install in piping system between fuel supply and heater.Locate sediment trap where trapped matter is not likely to freeze. Asediment trap traps moisture and contaminants. This keeps themfrom going into heater controls. If sediment trap is not installed oris installed wrong, heater may not run properly.IMPORTANT: Hold pressure regulator with wrench when con-necting it to gas piping and/or fittings. Do not over tighten pipeconnection to regulator. The regulator body could be damaged.INSTALLATIONContinuedTee JointReducerBushing to1/8" NPT1/8" NPTPlug TapTestGaugeConnection*TeeJointPipeNippleCapPressureRegulatorHeaterCabinet3/8" NPTPipe NippleGroundJoint UnionSedimentTrap3"MinimumNatural GasFrom Gas Meter(4" W.C. to 10.5"W.C.

See guidelines underConnectingto Gas Supply, page 8.Pressure Testing Gas Supply Piping SystemTest Pressures In Excess Of 1/2 PSIG (3.5 kPa)1. Disconnect appliance with its appliance main gas valve (controlvalve) and equipment shutoff valve from gas supply piping sys-tem. Pressures in excess of 1/2 psig will damage heater 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 or opening main gas valvelocated on or near gas meter for natural gas, or using com-pressed air.4. Check all joints of gas supply piping system. Apply a non-corrosive leak detection fluid to all joints. Bubbles formingshow a leak.5. Correct all leaks at once.6. Reconnect heater 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 14).2. Pressurize supply piping system by either opening propane/LPsupply tank valve for propane/LP gas or opening main gasvalve located on or near gas meter for natural gas, or usingcompressed air.INSTALLATIONConnecting To Gas Supply (Cont.)Checking Gas ConnectionsEquipmentShutoff Valve*
