INSTALLATION

Continued

WARNING:Neveruseanopen flame to check for a leak. Apply a noncorrosive leak detection fluid toalljoints.Bubblesformingshow a leak. Correct all leaks at once.

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.

PRESSURE TESTING HEATER GAS

CONNECTIONS

 

1.

Open equipment shutoff valve (see Figure 17).

2.

For natural gas open main gas valve located

 

on or near gas meter. For propane/LP gas open

position.

 

Check all joints from equipment shutoff valve

 

to thermostat gas valve (see Figure 18 or 19).

 

Apply a noncorrosive leak detection fluid to

5.

all joints. Bubbles forming show a leak.

Correct all leaks at once.

 

6.

Light heater (see Operating Heater, page 14).

7.

Check all other internal joints for leaks.

Turn off heater (see To Turn Off Gas to Appli-

ance, page 15).

 

Connect ignitor wire and replace front panel.
