1.Check the door gasket for damage or imbedded debris prior to installation.

Explosion Hazard

,Replace viewpo_ if gUass is missing or damaged,

•Failure to do so _n result in death_ exp/[osion, or fire,

2.Inspect the viewport for damage and replace as required.

3.Insert the burner door assembly into the combustion chamber and slide it completely forward. Note: When inserting the burner door assembly, tip the burner end up slightly to ensure it engages with the burner bracket.

4.Inspect the door gasket and make sure there is no fiberglass insulation between the door gasket and the combustion chamber (See Figure 30).

5.Replace the two screws, which secure the burner door assembly to the combustion chamber and tighten securely. Once the burner door assembly is tightened, visually inspect the door gasket between the burner door assembly 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 burner door assembly and the combustion chamber.

6.Reconnect the manifold tubing, pilot tubing, and thermocouple to the thermostat. Do not cross-thread or apply any thread sealant to these fittings. The thermocouple nut should be started and turned all the way in by hand. An additional 1/2 - 3/4 turn with a 7/16" open end wrench will then be sufficient to seat the lockwasher.

7.Reconnect the igniter wire.

8.Turn gas supply on and refer to the "Operating Instructions".

9.Check for leaks by brushing on an approved noncorrosive leak detection solution. Bubbles will show a leak. Correct

any leak found.

10.Replace the outer door.

Piezoelectric Igniter System

The piezoelectric igniter system consists of the igniter button, electrode, and wire. The pilot is ignited by an electric spark generated when the igniter button is pressed. The electrode should be centered between the pilot and thermocouple. (See Figure 31 ). Use only factory authorized piezoelectric igniter parts for replacement.

Testing the Igniter System

Turn off the gas to the water heater at the manual gas shut-off valve. Watch the electrode tip while activating the igniter. A visible spark should jump from the electrode. To avoid shock, do not touch the burner or any metal part on the pilot or pilot assembly. If no spark is visible, check the wire connections and make sure the electrode is not broken. Replace the electrode if defective. NOTE: The electrode is part of the pilot assembly and cannot be replaced separately. Dirt and rust on the pilot or electrode tip can prevent the igniter spark. Wipe clean with a damp cloth and dry completely. Rust can be removed from the electrode tip and metal surfaces by lightly sanding with an emery cloth or fine grit sandpaper.
