31. Reconnect the two white wires to the vent switch now
located just above the return header.
32. Reconnect the blower pressure switch tubing to the
blower housing.
33. Replace the EMI shield (metal plate) located over the
blower by reinstalling the two hex head screws.
34. Slide the upper right side panel back into the corner
posts on the right side of the heater. Push it down
until the tabs on the panel lock into the top of the
corner posts.
36. Install the flat return header side cover plate
(removed from the left side of the heater) on the right
side to cover the return header by replacing the four
philips head screws, one in each corner.
37. Slide the upper left side panel back into the corner
posts on the left side of the heater. Push it down until
the tabs on the panel lock into the top of the corner
posts.
38. Remove the button plug from the inlet/outlet side
cover plate.
39. Reinstall the inlet/outlet header side cover plate
located under the inlet/outlet header. It is held with
four philips head screws, one in each corner.
26. Route the wires that attach to the temperature sensor
along the copper siphon loop, back to the right side of
the heater. Reconnect the wires to the tabs on the
back of the control panel (marked as J4-1 and J4-2).
27. Use plastic wire ties to refasten the temperature
sensor and high limit switch wires to the copper
siphon loop. Bundle the wires near the control panel
and fasten them with a wire tie.
28. Replace the flue collector so that the blower mount is
in the same position as it was before the heat
exchanger reversal. Be sure that the bottom of the
flue collector lies flat on the top of the combustion
chamber and that it covers all of the heat exchanger
tubes. Replace the hex head screws to fasten the flue
collector to the combustion chamber.
29. Reassemble the blower and exhaust vent to the flue
collector. Be sure that the blower is seated properly
on the gasket and fasten it to the flue collector with
four hex head screws.
30. Reconnect the fan wires to the terminal strip as
follows: (Terminal numbers are shown on wires
connected to the bottom of the terminal strip)
a. Black Blower wire to terminal 11
b. Blue Blower wire to terminal 10
c. Red Blower wire to terminal 9
