Replacing the Manifold/Burner Assembly

WARNING

Explosion Hazard

• Tighten both manifold door screws securely.

• Remove any fiberglass between gasket and

combustion chamber.

• Replace viewport if glass is missing or damaged.

• Replace two piece wire connector if missing or

removed.

• Replace door gasket if damaged.

• Failure to follow these instructions can result in

death, explosion, or fire.

1. Check the door gasket for damage or imbedded

debris prior to installation.

2. Inspect the view port for damage and replace as

required.

3. Insert the manifold/burner 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 (Figures 32 & 33).

4. Inspect the door gasket and make sure there is no

fiberglass insulation between the gasket and the

combustion chamber.

5. Replace the two screws, which secure the

manifold/burner assembly door to the combustion

chamber and tighten securely. Once the manifold/

burner assembly door is tightened, visually inspect

the door gasket between the manifold/burner

assembly door and the combustion chamber

for spaces or gaps that would prevent a seal.

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. During the following procedure, do not cross-

thread or apply any thread sealant to any of the

fittings listed below. First, reconnect the manifold

tubing to the gas control valve/thermostat. NOTE:

L.P. gas systems use reverse (left-hand) threads

on the manifold tube.

NOTE: If a ferrule nut needs to be installed for the

pilot tube, locate the one provided with your parts

kit. Install it in the gas control valve/thermostat at

the pilot location, hand tight only. Next, insert the

pilot tube into the ferrule nut until it bottoms out.

NOTE: Hold the tube in this position. Tighten the

ferrule nut with a wrench until the crimp connection

seals to the pilot tube. Continue to tighten until

the nut is tight in the gas control valve/thermostat.

Finally, start the thermocouple nut and turn it all the

way in by hand. An additional quarter turn with a

3/8” open-end wrench will then be sufficient to seat

the lockwasher. When you are finished, connect

the two wire leads that go to the thermal switch.

7. Reconnect the igniter wire.

8. Turn gas supply on and refer to the Lighting

Instructions.

9. With the burner lit, check the gas control valve/

thermostat supply line, two piece wire connector,

manifold tube, and pilot tube connections for

leaks. Check for leaks by brushing on an approved

noncorrosive leak detection solution. Bubbles

forming indicate a leak. Correct any leak found.

IMPORTANT: All leaks must be fixed immediately.

10. Replace the outer door.
