CAUTION: For propane/LP gas, make sure external regula- tor has been installed between propane/LP supply and heater. See guidelines under Connect- ing to Gas Supply, page 11.

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 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.

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 fit- tings 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 for natural gas (see Figure 17) or propane/LP supply tank for propane/LP gas, to equipment shutoff valve (see Figure 18). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4. Correct all leaks at once.

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

2. For natural gas open main gas valve located on or near gas meter. For propane/LP gas 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 (see Figure 17 or 18). Apply a 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 14). Check all other internal joints for leaks.

7. Turn off heater (see To Turn Off Gas to Appli- ance, page 15).

8. Replace front panel.
