How to Care For Your Furnace

Service, repair or maintenance of the furnace, vent or gas system
should only be attempted by a qualified service technician.
The burner and control of the furnace should be cleaned and
checked at least once each year by a qualified service technician.
If there is any indication that the furnace is operating improperly,
turn it off and have it checked immediately.
Lint and dust may be vacuumed from the interior of the furnace,
when it is cool, by removing the floor grille. The control and main
burner can be blown free of dust and lint with a vacuum cleaner.
