leak. Correct all leaks immediately.
CAUTION: Make sure external
regulator has been installed be-
tween gas supply and heater. See
guidelines under
Connecting to Gas
Supply (page 7).

Pressure Testing Gas
Supply Piping System
Test Pressures In Excess Of 1/2
PSIG(3.5kPa)
1. Disconnect heater with its
appliance main gas valve (control
valve) and equipment shutoff valve
from gas supply piping system.
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 using compressed air or
opening gas supply tank valve.
4. Check all joints of gas supply
piping system. Apply mixture of
liquid soap and water to gas
joints. Bubbles forming show a
leak.
5. Correct all leaks immediately.
6. Reconnect heater and equipment
shutoff valve to gas supply. Check
reconnected fittings for leaks.

Gas Connections
1. Open equipment shutoff valve
(see Figure 8).

CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct all
leaks immediately.
INSTALLATION

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
(Figure 9). Apply mixture of liquid
soap and water to gas joints.
Bubbles forming show a leak.
5. Correct all leaks immediately.
6. Light heater (see
Operating
Heater , page 11).Check all other
internal joints for leaks.
7. Turn off heater (see To Turn Off
Gas to Appliance
, page 11).
Test Pressures Equal To or
Less Than 1/2 PSIG(3.5 kPa)
1. Close equipment shutoff valve
(see Figure 8).
2. Pressurize supply piping system
by either using compressed air or
opening gas supply tank valve.
3. Check all joints from gas meter to
equipment shutoff valve(see
Figure 9). Apply mixture of liquid
soap and water to gas joints.
Bubbles forming show a leak.
4. Correct all leaks immediately.
