Owner's Information
The problem solver.
A furnace is not a household appliance. It is complex and requires
professional maintenance and repair.
That's why attempts at "do-it-yourself" repairs on an in-warranty
unit may void the remainder of your warranty.
Other than performing the simple maintenance recommended in
this manual, you should not attempt to make any adjustments to
your furnace. Your dealer will be able to take care of any questions
or problems you may have. A periodic inspection of your furnace
should be made by a qualified service agency at the start of each
heating season.
Save time and money. Before calling for service, check the following:
