INSTALLATION
Continued
We recommend that you install a sediment
trap in supply line as shown in Figures 20
and 21 on page 12. Locate sediment trap
where it is within reach for cleaning. Install
in piping system between fuel supply and
heater. Locate sediment trap where trapped
matter is not likely to freeze. A sediment
trap traps moisture and contaminants. This
keeps them from going into heater controls.
If sediment trap is not installed or is in-
stalled wrong, heater may not run properly.
CAUTION: Avoid damage to
regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or fittings.
CHECKING GAS
CONNECTIONS
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply a
noncorrosive leak detection fluid
to all joints. Bubbles forming show
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 appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing 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 ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.

4. Check all joints of gas supply piping
system. Apply a noncorrosive leak de-
tection fluid to gas joints. Bubbles
forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment
shutoff valve to gas supply. Check re-
connected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 22).
2. Pressurize supply piping system by ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.
3. Check all joints from gas meter to
equipment shutoff valve (see Figure
23). Apply a noncorrosive leak detec-
tion fluid to gas joints. Bubbles form-
ing show a leak.
4. Correct all leaks at once.

Pressure Testing Heater Gas
Connections
1.
Open equipment shutoff valve (see Fig-
ure 22).
2. Open main gas valve located on or near
gas meter.
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 23).
Apply a noncorrosive leak detection
fluid to gas joints. Bubbles forming
show a leak.
5.
Correct all leaks at once.
6.
Light heater (see Operating Heater,
pages 14 through 17). Check all other
internal joints for leaks.
7.
Turn off heater (see To Turn Off Gas to
Appliance, remote-ready models, page
15, manual-variable models, page 16).
