Correct allleaks at 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.CAUTION: Make sure external regulator has beeninstalled between propane/LP supply and heater. Seeguidelines underConnecting to Gas Supply, page 12.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 noncorrosiveleak detection fluid to all joints. Bubbles forming show 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 17).2. Pressurize supply piping system by either opening propane/LP sup-ply tank valve for propane/LP gas or opening main gas valve lo-cated on or near gas meter for natural gas, or using compressed air.3. Check all joints from gas meter for natural or propane/LP sup-ply to equipment shutoff valve (see Figure 18 or 19). Apply anoncorrosive leak detection fluid to all joints. Bubbles form-ing show a leak.4. Correct all leaks at once.CHECKING GAS CONNECTIONSFigure 17 - Equipment Shutoff ValveFigure 18 - Checking Gas Joints (Propane/LP Gas Only)Thermostat Gas Valve orControl Valve LocationPropane/LPSupply TankEquipment Shutoff ValveOpenClosedEquipmentShutoffValvePressure Testing Heater Gas Connections1. Open equipment shutoff valve (see Figure 17).2. Open main gas valve located on or near gas meter for naturalgas or open propane/LP supply tank valve.3. Make sure control knobs of heater are in the OFF position.4. Check all joints from equipment shutoff valve to thermostat gasvalve (Thermostat-Controlled Models) or control valve (Remote-Ready Models) (see Figure 18 or 19). Apply a noncorrosiveleak detection fluid to all joints. Bubbles forming show a leak.5. Correct all leaks at once.6. Light heater (see Operating Heater, pages 17 through 21).Check all other internal joints for leaks.7. Turn off heater (see To Turn Off Gas to Appliance, page 18 [Ther-mostat-Controlled Models] or page 20 [Remote-Ready Models]).INSTALLATIONChecking Gas ConnectionsFigure 19 - Checking Gas Joints (Natural Gas Only)Thermostat Gas Valve orControl Valve LocationGas MeterEquipment Shutoff Valve
