Maintenance

& Annual Inspection

1) Replace Delevan nozzle with exact capacity, angle and pattern as supplied.

2) Replace vestibule mounted oil filter with AF-1 filter.

3) Replace condensate neutralizer with part number CCR-1.

4) Remove air handler assembly (slide out) and inspect the bottom (upflow configuration) of the

secondary heat exchanger. Loosen accumulated foreign matter with soft brush and vacuum
clean.

5) Perform all routine safety switch function checks.

6) Perform combustion analysis as described on page 18 Burner Adjustment.

7) Do not remove rear access panel of heat exchanger. Internal cleaning of the primary or

secondary heat exchangers are not required (unless satisfactory combustion analysis

cannot be achieved).

! CAUTION

The ceramic combustion chamber located in the primary heat exchanger

should not

be handled

once it is cured at startup. Structural damage will occur, if handled and if broken the furnace will be
rendered inoperative.

NOTE:

If the secondary heat exchanger turbulators have a light coating of soot, this is normal and will not

affect the efficiency of the furnace.
