Furnace location
Before you start!
It is very important you check with your dealer, local
fire department, or building inspector. They will be
able to inform you of any state or local codes per-
taining to the location and installation of your fur-
nace.
The ideal location for your furnace is centrally located
in the basement. This allows for an even heat distri-
bution by having all the duct work approximately the
same length. Ideal locations cannot always be used
for one reason or another, therefore, let's look at some
alternatives.
If your home does not have a basement, but a utility
room or garage, make sure there is enough space to
maintain the required clearances stated on the label
located on the furnace. Also, read about combus-
tion air.
Chimney location is also critical. The furnace must
be placed as close as possible to the chimney. You
want the chimney connector (smoke pipe) to have
a minimum of elbows, two (2) or less. Also, the chim-
ney connector should not have to run more than six
(6) feet to the chimney.
CAUTION: The warm-air supply outlet of the Furnace
should not be connected to the cold-air return inlet
of the central furnace because a possibility exists of
components of the central furnace overheating and
causing the central furnace to operate other than as
intended.
After installation, be sure the measured external static
pressure of the central and Furnace is not greater than
those marked on the nameplates.
INSTALLATION #3
The baffle on this system should be made the full width
of the furnace plenum in order to properly direct the
air into the distribution ducts.
INSTALLATION #1
With this installation, a back draft damper (optional)
is inserted into the heat run before the plenum of the
existing furnace to prevent air from the existing fur-
nace to blow back into the furnace when it is not in
use. When a back damper is employed, it should be
located as close to the existing furnace plenum as
practical.
INSTALLATION #2
Extending the hot air duct from the furnace into the
existing plenum will help direct the flow of air from
the furnace as well as the flow in the existing furnace.
Ducting entering the existing plenum at an angle (ap-
proximately 45 degrees) will facilitate air flow from
the furnace while diverting air from the existing fur-
nace.
