PRESSURE TESTING HEATER GAS
CONNECTIONS
1. Open equipment shutoff valve (see Fig-
ure 13).
2. Open main gas valve located on or near
gas meter for natural gas or open propane
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 fluid
to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see
Lighting Instructions
on
page 19). Check all other internal joints
for leaks.
7. Turn off heater (see
To Turn Off Gas Ap-
pliance
, page 20).

WARNING: Test all gas piping
and connections, internal and
external to unit, 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. 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 supply tank valve for
propane 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
fluid 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
fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1.
Close equipment shutoff valve (see Figure 13).
2. Pressurize supply piping system by either
opening propane supply tank valve for
propane 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 pro-
pane supply to equipment shutoff valve
for propane (see Figure 14 or 15). Apply
a noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak.
4. Correct all leaks at once.
