Other than performing the simple maintenance rec-
ommended 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.
In the event that electrical, fuel, or mechanical failures
occur, immediately turn the gas supply off at the man-
ual gas valve located on the gas pipe leading to the fur-
nace before turning off electrical power to the furnace.
Contact a qualified service agency.
Keep your furnace looking like new for years.
Clean the enamel finish of your furnace with ordi-
nary soap and water. For stubborn grease spots, use
a household detergent. Lacquer thinner or other syn-
thetic solvents may damage the finish.
