INSTALLATION
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 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.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure
15).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve or
using compressed air.
3. Check all joints from propane/LP tank to
equipment shutoff valve (see Figure 16).
Apply a noncorrosive leak detection uid
to all joints. If bubbles form, there is a leak.
4. Correct all leaks at once.

PRESSURE TESTING HEATER GAS
CONNECTIONS
1. Open equipment shutoff valve (see Figure
15).
2. Open propane/LP 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 16).
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 16).
Check all other internal joints for leaks.
7. Turn off heater (see To Turn Off Gas Ap-
pliance, page 18).
8. Replace lower front panel.
