CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater.SeeguidelinesunderCon- necting to Gas Supply, page 13.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using com- pressed air.

4.Check all joints of gas supply piping system. Apply a noncorrosive leak 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 16).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.

3.Check all joints from gas meter to equipment shutoff valve for natural gas or propane/LP supply to equipment shutoff valve for pro- pane/LP (see Figures 17 and 18). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4.Correct all leaks at once.

PRESSURE TESTING HEATER GAS CONNECTIONS

1.Open equipment shutoff valve (see Figure 16).

2.Open main gas valve located on or near gas meter for natural gas or open propane/LP supply tank valve.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from equipment shutoff valve to thermostat gas valve (Thermostat-Con- trolled Models) or to control valve (Manu- ally-Controlled Models) (see Figures 17 and 18). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, page 19 [manually-controlled models] or page 21 [thermostatically-controlled models]). Check all other internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appli- ance, page 20 [manually-controlled models] or page 22 [thermostatically-controlled models]).
