riodic preventative maintenance on this
equipment.
The person most familiar with the equip-
ment in your system is a YORK dealer.
The YORK dealer can ensure your main-
tenance program meets the conditions
of the "YORK Warranty", maximize the
efficiency of the equipment, and service
your unit within the mandated guidelines
with regard to unlawful discharge of re-
frigerants.
The inspection should include heating
element, vent piping, to see that they are
clear and free of obstructions and with-
out holes or corrosion. Make sure the
horizontal run of the vent system slopes
upward and all of the connections are
secure. Make sure the return air duct
connections are physically sound and
sealed to the furnace casing. Make sure
no sagging, cracks, gaps, etc. exist
around the base of the furnace.
Routine periodic maintenance checks
should be done on your furnace at least
every time you check the filters. Proper
burner flame appearance is shown below.
