CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

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 (con- trol valve) and equipment shutoff valve from gas supply pip- ing 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 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.

4.Check all joints of gas supply piping system. Apply a noncor- rosive leak detection fluid to gas 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)

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 14 and 15). Check all other internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appliance, page 15).

8.Replace front panel.

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 to equipment shutoff valve (see Figure 21) for natural gas, or to propane/LP supply tank (see Figure 22). Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Heater Gas Connections

1.Open equipment shutoff valve (see Figure 20).

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

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 21 or 22). Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.
