ABOUT YOUR CENTRAL
FURNACE SYSTEM
NORDYNE has been involved in the design of
products for the manufactured home industry
since the first manufactured home or trailer was
built.
NORDYNE originated the sealed combustion
system, which separates the furnace combus-
tion system from the living area of the home,
now a standard for the manufactured home
industry.
NORDYNE engineers developed the first cen-
tral heating system and the first central air
conditioner for manufactured homes.
NORDYNE is dedicated to bringing to its cus-
tomers the finest heating and cooling comfort
possible. NORDYNE constantly seeks to fur-
ther refine its products to continuously provide
exceptional comfort.
Follow the instructions in this booklet carefully
and this appliance will provide many years of
superior performance.
If you wish to cool your home automatically with
a central air conditioning system investigate the
excellent NORDYNE cooling systems avail-
able from your heating and cooling contractor.
These systems are designed to work best with
your NORDYNE furnace and have been care-
fully engineered to deliver optimum performance
when mated with NORDYNE manufactured
home furnaces.
NORDYNE also offers water heaters, fire-
places and ventilating systems specifically de-
signed for manufactured housing applications.
Check with your manufactured home retailer,
your heating and cooling contractor or your
