We recommend that you install sedi-
ment trap in the supply line as shown
in Figure 14. Locate sediment trap
where it is within reach for cleaning.
Locate sediment trap where trapped
matter is not likely to freeze. A sedi-
m ent tr ap tr ap s m ois tur e and
contaminants. This keeps them from
going into heater controls. If sediment
trap is not installed or is installed
incorrectly, heater may not run
properly.
IMPORTANT: Hold pressure regula-
tor with wrench when connecting it to
gas piping and/or fittings.
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
flame to check for leaks. Apply a
mixture of liquid soap and water
to all joints. Bubbles forming
show a leak. Correct all leaks
immediately. Press Testing Gas
Supply Piping System.
Prss Testing Gas Supply Pip-
ing System
Test Pressure in Excess Of 1/2
PSIQ (3.5 K Pa)
1.
Disconnect appliance with its
appliance main gas valve (control
valve) and equipment shutoff valve
from gas supply piping system.
Pressure 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 main gas valve located on
or near gas tank .
4. Check all joints of gas supply pip-
ing system. Apply a mixture of liq-
uid 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.
Test Pressures Equal To or Less
Than 1/2 PSIQ (3.5 K Pa)
1. Close equipment shutoff valve (see
Figure 15).
2. Pressurize supply piping system by
either using compressed air or
opening main gas valve located on
or near gas supply tank.
3. Check all joints from gas tank to
equipment shutoff valve (see Fig-
ure 16). Apply mixture of liquid soap
and water to gas joints. Bubbles
forming show a leak.
4. Correct all leaks immediately.

Gas Connections
1. Open equipment shutoff valve
(see Figure 15).
2. Open main gas valve located
on or near gas tank .
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 mixture
of liquid soap and water to gas
joints. Bubbles forming show a
leak.
5. Correct all leaks immediately.
6 Light heater (see Operating
Instructions, page 16-page 19).
Check the rest of the internal
joints for leaks.
7. Turn off heater (see To Turn Off
Gas to Appliance, page 17).
