22. Maintenance And Service
Routine Maintenance By Home Owner
• Arrange for professional servicing of furnace by the
service or installation contractor annually.
•
Homeowner is to maintain air filter or filters. A dirty
filter can cause furnace to over-heat, fail to maintain
indoor temperature during cold weather, increase fuel
consumption and cause component failure.
•
Inspect, clean or replace filter monthly.
•
Furnace is supplied with semi-permanent type filter.
If filter is damaged, replace with filters of same size
and type.
•
During monthly filter inspection, inspect general
condition of furnace. Watch for signs of oil leaks in
vicinity of oil burner, soot forming on any external
part of furnace, soot forming around joints in vent
pipe, etc. If any of these conditions are present,
please advise your service or installation contractor.
