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.

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.

External Inspection & Cleaning of the
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.
