tion of airflow. Allow filter to dry.

Your furnace represents an important investment in
your family’s comfort and your home’s value. To keep
it performing properly and as a preventative to future
problems, have a trained service specialist give your
furnace a professional check-up annually. The fol-
lowing checklist can be used as a guideline to proper
service:
Check flue and secondary tube passage ways including
chimney — clean if necessary.
Change oil filter.
Change nozzle.
Check and adjust combustion and draft.
Inspect all vent piping inside structure for deterioration
and vent terminations outside the structure for blockage.
Check oil pipes leading to and inside of your furnace
for leaks.
Inspect and clean the blower motor and wheel.
Inspect and change or clean air filters if necessary.
Inspect all supply- and return-air ducts for obstruc-
tions, air leaks, and insulation. Remedy any problem
when necessary.
