Replacing the Burner Door Assembly Fire or Explosion Hazard ° Tighten both manifolddoor screws securely. • Remove any flbergtassbetween 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, GASCONTROLVALVE BURNERDOOR ASSEMBLY'_ installing, using or servicing !_ Read inswtrautcetriohnemaatenruai before 1. Check the door gasket for damage or imbedded debris prior to installation. FIGURE 30. 9. Check for leaks by brushingon an approved noncorrosive leak detectionsolution. Bubbleswill show a leak. Correct any leak found. 10. Replace the outer door. Piezoelectric Igniter System The piezoelectric igniter system consists of the igniter button, electrede, and wire. The pilct is ignited by an electdc spark generated when the igniter button is pressed. The electrode should be centered between the pilot and thermoceuple. (See Figure 31). Use only factory authorized piezoelectric igniter parts for replacement. 2. Inspect the viewport for damage and replace as required. PILOT PILOT BRACKET 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 insulationbetween 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 combustionchamber for spaces or gaps that would prevent a seal. IMPORTAN'E 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 therrnocoupleto the thermostat. Do not cress-thread or apply any thread sealant to these fittings. The thermoceuple 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 Iockwasher. _S NAP_N coNTHERoOCOU PLE Q ELECTRODE FIGURE 31.

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 igniterspark.
