INSTALLATION
INSTALLATION
natural gas, verify that “NAT”
is marked on the exposed
end of the fitting. “NAT”
must face outward (toward
you). See Figure 26. If “LP”
faces outward, repeat step 2.
4. Replace the cap.
Installing the Conversion
Manifold Assembly
1. Check the door gasket for
damage or imbedded debris prior
to installation.
2. Inspect the view port for damage
and replace as required (Figure
25, page 19).
3. Insert the conversion manifold
assembly into the burner
compartment, making sure that
the tip of the manifold tube
engages in the slot of the bracket
inside the combustion chamber.
See Figure 27 and Figure 28.
Tip must engage slot in bracket.

4. Inspect the door gasket and
make sure there is no fiberglass
insulation between the gasket
and the combustion chamber
(Figure 28).
5. Replace the two screws that
secure the manifold assembly
door to the combustion chamber,
then tighten them securely
(Figure 25, page 19). There
should be no space between the
gasket part of the manifold door
and the combustion chamber.
IMPORTANT: Do not operate the
water heater if the door gasket
does not create a seal between
the manifold door and the
combustion chamber.
6. Reconnect the manifold tube
and pilot tube to the gas control
valve/thermostat (Figure 25, page
19). Do not cross-thread or
apply any thread sealant to the
fittings. IMPORTANT: If you were
supplied with a new ferrule nut in
a parts kit, follow these steps to
connect the pilot tube:
A. Install the ferrule nut into the
gas valve at the pilot tube
location, hand tight only.
B. Insert the pilot tube into the
ferrule nut until the tube
bottoms out, then tighten
the nut with a 7/16” wrench
until the crimp connection
seals to the pilot tube.
C. Continue to tighten until the
nut is tight in the gas valve.
7. Connect the white and red
thermopile wires to the gas
control valve/thermostat. See
Figure 25, page 19.
8. Reconnect the igniter wire.
9. If you are working with a water
heater that is already installed,
complete the following sub-steps.
If this is a new installation, skip
the following sub-steps and go to
Step 13.
A. Turn the gas supply on.
B. Follow the Lighting
Instructions.
C. With the main burner
lit, check for leaks at
the manifold and pilot
connections by brushing on
an approved non-corrosive
leak detection solution.
If such a solution is not
available, use a mixture of
hand dish washing soap
and water (one part soap
to 15 parts water). Bubbles
forming indicate a leak.
Correct any leak found.
D. Verify proper operation;
replace outer door.
Step 13:
Make Gas Connec ons
The Gas Water Heater Hook-Up Kit
(available at your local plumbing sup-
plier) includes a fl exible gas connector
with compression fi  ngs to connect
the home’s gas line to the water
heater’s gas control valve. Follow the
kit’s installa on instruc ons to a ach
the fl exible gas connector.
