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.

CAUTION: Make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, page 12.

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 sys-

 

tem. 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

Pressure Testing Heater Gas Connections

1.Open equipment shutoff valve (see Figure 17).

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 knobs of heater are in the OFF position.

4.Check all joints from equipment shutoff valve to thermostat gas valve (Thermostat-Controlled Models) or control valve (Remote- Ready Models) (see Figure 18 or 19). 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, 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]).

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 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 a

 

noncorrosive leak detection fluid to all joints. Bubbles form-

 

ing show a leak.

4.

Correct all leaks at once.
