WARNING: Never use an open

ame to check for a leak. Apply

a noncorrosive leak detection

uid to all joints. If bubbles form,

there is a leak. Correct all leaks

at once.

WARNING: Test all gas piping

and connections for leaks after

installing or servicing. Correct

all leaks at once.

PRESSURE TESTING GAS SUPPLY PIPING SYSTEM

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

1. Disconnect heater 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 equip-

ment 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 sys-

tem. Apply noncorrosive leak detection

uid to all joints. If bubbles form, there

may be a leak.

5. Correct all leaks at once.

6. Reconnect heater and equipment shutoff

valve to gas supply. Check reconnected

ttings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1. Close equipment shutoff valve (see Fig-

ure 12).

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 equip-

ment shutoff valve for natural gas or

propane/LP supply to equipment shutoff

valve for propane/LP (see Figure 13 or

14). Apply a noncorrosive leak detection

uid to all joints. Bubbles forming show a

leak.

4. Correct all leaks at once.
