ABOUT YOUR CENTRAL
FURNACE SYSTEM
NORDYNE has been involved in the
design of products for the manufac-
tured home industry since the first
manufactured home or trailer was
built.
NORDYNE originated the sealed
combustion system, which separates
the furnace combustion system from
the living area of the home and is now
a standard for the manufactured home
industry.
NORDYNE engineers developed the
first central heating system and the
first central air conditioner for manu-
factured homes.
NORDYNE is dedicated to bringing
to its customers the finest heating
and cooling comfort possible.
NORDYNE constantly seeks to fur-
ther refine its products to continu-
ously provide exceptional comfort.
Follow the instructions in this booklet
carefully and this appliance will pro-
vide many years of superior perfor-
mance.
If you wish to cool your home auto-
matically with a central air condition-
ing system investigate the excellent
NORDYNE cooling systems available
from your heating and cooling con-
tractor. These systems are designed
to work best with your NORDYNE
furnace and have been carefully en-
gineered to deliver optimal perfor-
mance when mated with NORDYNE
manufactured home furnaces.
NORDYNE also offers water heat-
ers, fireplaces and ventilating sys-
tems specifically designed for manu-
factured housing applications. Ask
your manufactured home retailer, your
heating and cooling contractor, or your
distributor for more information. Write
directly to the factory (PO Box 46911,
St. Louis, MO 63146) if you are un-
able to locate a source for NORDYNE
manufactured housing products in
your area.
1. Furnace Location
The furnace area and the vicinity of
any other gas appliance must be kept
clear and free of combustible materials,
gasoline, and other flammable vapors
and liquids. Do not store or use
flammable items such as paint,
varnish, or strippers in the vicinity of
the furnace.
Do not use the furnace closet or area
next to the furnace as a storage area.
This area must be kept clear, clean,
and free of lint. The furnace must also
be kept clear of loose or exposed
insulation materials. Examine the
furnace area when the furnace is
installed or when insulation is added.
Some insulation materials may be
combustible.
Do not use this furnace if any part has
been under water. Immediately call a
qualified service technician to inspect
the furnace and to replace any part of
the control system and any gas control
which has been under water.
Familiarize yourself with the controls
that shut off the gas and electrical
power to the furnace. If the furnace is
to be shut down for an extended period
of time, turn off both the gas and
electrical power. For your safety
always turn off both the gas and
electrical power before performing
service or maintenance on the furnace.
2. Combustion Air Supply
A furnace needs an adequate supply
of combustion and ventilation air for
proper and safe operation. Follow the
installation instructions included with
the furnace to properly vent air to the
combustion air inlet and exhaust the
products of combustion to the outside
from the exhaust vent.
If the furnace is operated with a
restricted combustion air supply, the
pressure switch will open, turning off
the gas supply to the burners. (See
Figure 1). DO NOT install a jumper
wire across this switch to defeat its
function. If this switch must be
replaced, use only authorized
replacement parts from your
authorized distributor.
