Replacing the Pilot Assembly

1.Remove the manifold assembly as directed previously.

2.Remove the retainer clip from the back of the two piece wire connector and remove the two piece wire connector from the manifold door (Figure 25).

3.Locate and remove the screws on the underside of the burner. Remove the screw securing the pilot assembly to the manifold.

4.Using a wrench loosen the nut securing the pilot tube to the pilot assembly. NOTE: To prevent any bending of the pilot bracket, use pliers to hold the pilot assembly bracket while loosening the pilot nut.

5.Pull the pilot tube from the pilot assembly (Figure 26).

IMPORTANT: Be careful not to bend or alter the position of the pilot assembly components.

6.Push the new pilot assembly connectors through the hole in the manifold door (See Figure 25). Reconnect the pilot tube and tighten the nut securing it to the pilot assembly. IMPORTANT: Keep the pilot orifice in the pilot when making the connection. DO NOT operate the water heater without the pilot orifice installed. Reattach the pilot assembly to the manifold.

7.Reattach the burner and secure with the screws removed earlier. Note: See figure 24 for correct burner orientation.

8.Position the new thermopile wires through the lower opening of the two piece wire connector (Figure 25). Be sure igniter wire is positioned through the upper opening of the two piece wire connector.

External Inspection & Cleaning of the Flame-trap

Inspect the wrap around filter periodically to check for lint, dust, or other debris that may have accumulated on it. If the water heater is installed in an easily accessible location, remove the wrap around filter and clean with soap and warm water. If the installation is not easily accessible use a vacuum with a brush attachement to clean the wrap around filter. Rotate the filter around the base of the water heater, vacuuming each exposed section until the wrap around filter is clean. Although not likely to occur, if debris collects on the flame-trap, use a vacuum, compressed air, or a soft bristle brush to remove it. Note: If unable to inspect or clean the flame trap from underneath, follow the “Cleaning the Combustion Chamber and Flame-trap” instructions.
