SECTION 9: MAINTENANCE
Understanding Maintenance
Servicing your Clean Burn furnace in a timely manner is very important to keep your furnace running in peak
condition. Just as an automobile requires periodic maintenance such as oil changes, engine tune-ups, etc. your
Clean Burn furnace also requires regularly scheduled service.
WARNING: Failure to maintain and/or improper servicing by unqualified personnel may
adversely affect the proper, safe operation of your furnace, may reduce the service life of your
furnace, and may void your warranty.
The following chart summarizes all the service intervals which are required to maintain your furnace. Service
instructions/procedures for these activities are included in this chapter.
Maintenance Activity Interval
Periodic Burner Inspection Monthly
Cleaning the canister filter Before vacuum gauge reads 10" HG of vacuum
Servicing the metering pump At least once a year
Cleaning the check valve/screen At least once a year
Cleaning water/sludge out of tank At least once a year
Cleaning out ash 800 - 1000 hours as indicated on the hour meter*
Annual burner tune-up At least once a year
*It is very important to clean ash from the furnace on schedule. Normal use of the furnace requires
clean-out at least twice during the heating season. Heavy, around-the-clock usage requires more
frequent clean-out. For instance, one month of continual running of the furnace is 720 hours (24 hours x 30
days = 720 hours).
NOTE: IMPORTANT! Record all maintenance activities in the Maintenance Record provided in Appendix C.

Periodic Burner Inspection
Following initial start up of the burner, you should inspect the operation of the burner periodically--ideally on a
monthly basis. Doing so ensures that the system is functioning efficiently and safely.
Follow these guidelines for inspecting the operation of the burner:
• Visually inspect the flame length through the observation
port; the flame should extend no more than one-half of
the way down the combustion chamber.
-If the flame is diminishing or displays wide
variations, clean the canister filter and check
valve/screen (procedures provided in this
section).
-If the flame is firing too strongly (i.e. flame
touches back and/or side walls of the
combustion chamber), check the air pressure setting (see following guideline).
