User’s Information
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 recom-
mended in this manual, you should not attempt to make any
adjustments to your furnace. Your dealer will be able to take
The Problem Solver
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.
Keep your furnace looking like new for years.
Clean the enamel finish of your furnace with ordinary soap
and water. For stubborn grease spots, use a household
detergent. Lacquer thinner or other synthetic solvents may
damage the finish.
