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
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.
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 a 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.
3. Check all joints from gas supply to equip-
ment shutoff valve (see Figure 14 or 15).
Apply a noncorrosive leak detection uid
to all joints. If bubbles form, there is a leak.
4. Correct all leaks at once.

Equipment Shutoff Valve
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 13).
2. Pressurize supply piping system by either
opening main gas valve located on or near
gas meter or using compressed air.
PRESSURE TESTING HEATER GAS
CONNECTIONS
1. Open equipment shutoff valve (see Fig-
ure 13).
2. Open gas supply tank valve.
3. Make sure control knob of heater is in the
OFF position.
4. Check all joints from equipment shutoff
valve to control valve (see Figure 14 or
15). Apply a noncorrosive leak detection
uid to all joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Light heater (see Operation, page 14).
Check all other internal joints for leaks.
7. Turn off heater (see To Turn Off Gas Ap-
pliance, page 16).
8. Replace lower front panel.
