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.
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 |

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 |
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”. |
