LOCATION
The furnace must be installed on a level sur-
face, and as close to the center of the air
distribution system as possible. See Figure 1
for overall dimensions to determine the re-
quired clearances in hallways, doorways,
stairs, etc. to allow the furnace to be moved to
the installation point. The furnace must be in-
stalled so that all electrical components are
protected from water.
Minimum clearances to combustible materials
are listed in Table 4. Access for positioning and
servicing must be considered when locating
the unit.
This furnace is certified for use on wood
flooring. The furnace must be installed on a
solid surface and must be level front-to-back
and side-to-side. This furnace must not be
installed directly on carpeting, tile, or any com-
Table 4. Minimum Clearances
*Note: For 1” clearance, use a fully louvered door with at
least 400 square inches of free airflow area.

bustible material other than wood flooring. The
furnace may be installed on combustible floor-
ing when installed on a Nordyne duct connec-
tor (see Table 5).
The ductwork within 3 feet of the furnaces
without the A/C coil box must be installed such
that surfaces are at least 1/4" from combustible
materials.
When installed in a residential garage, the fur-
nace must be positioned so the burners and the
source of the ignition are located no less than
18 inches above the floor and protected from
physical damage by vehicles.
CIRCULATING AIR SUPPLY
! WARNING:
Products of combustion must not be
allowed to enter the return air openings
of the furnace or the circulating air
supply. Failure to prevent products of
combustion from being circulated into
the living space can create potentially
hazardous conditions including carbon
monoxide poisoning that could result in
personal injury or death.
The floor or platform on which the
furnace is mounted must provide sound
physical support of the furnace with no
gaps, cracks, or sagging between the
furnace and the floor or platform.
The circulating air ductwork must not
be connected to any other heat
producing device such as a fireplace
insert, stove, etc.
GENERAL
Plenums and air ducts must be installed in
accordance with the Standard for the Installa-
tion of Air Conditioning and Ventilating Systems
(NFPA No. 90A) or the Standard for the Instal-
lation of Warm Air Heating and Air Conditioning
Systems (NFPA No. 90B).
