the manifold component block (using a flat-blade

screwdriver), then remove the manifold component

block from the manifold door

(Figure 37).

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

External Inspection & Cleaning of the

Base-Ring Filter

1. At least annually check the base-ring filter (Figure 32)

for any dust or debris that may have accumulated on the

filter screen. NOTE: If the water heater is located in an

area that is subjected to lint and dirt, it may be necessary

to check the base-ring filter more frequently.

2. Follow the Lighting Instructions to turn off the water

heater and allow it to cool for 10 minutes before

attempting to clean the base-ring filter.

3. Use a vacuum cleaner with a hose attachment to remove

any dust or debris that may have accumulated on the

filter. NOTE: If unable to inspect or clean the base-ring

filter, follow the “Cleaning the Combustion Chamber and

Flame-arrestor” instructions.

4. After the base-ring filter has been cleaned, follow the

Lighting Instructions to return the water heater to service.
