WARNING:
This furnace is not approved for instal-
lation in mobile homes. Installation in
a mobile home could cause fire, prop-
erty damage, and/or personal injury.
Location
The furnace must be installed on a level surface,
and as close to the center of the air distribution
system as possible. See Table 3 for overall
dimensions to determine the required clear-
ances in hallways, doorways, stairs, etc. to allow
the furnace to be moved to the installation point.
The furnace must be installed so that all electri-
cal 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. 24 inches is the minimum required clear-
ance for servicing the unit. 30 inches is the
minimum required clearance for positioning the
unit. 36 inches is the recommended clearance
from the front of the unit. Please note that a
panel or door can be located such that the
minimum clearance on the rating plate is satis-
fied, but that panel or door must be removable
so as to allow the appropriate clearance.
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 combustible material other
than wood flooring.
DOWNFLOW MODEL WARNING
The design of the downflow furnace is certified
for natural or propane gas and for installation on
non-combustible flooring
. A special com-
bustible floor sub-base is required when install-
ing on a combustible floor. Failure to install the
sub-base may result in fire, property damage
and personal injury. The special downflow sub-
bases are factory supplied accessories, part
numbers 902974, 902677, 904108 and 904165.
904165 is an adjustable sub-base kit and it can
be used on all cabinet sizes. When the furnace
is installed on a factory or site-built cased air
conditioning coil, the sub-base is not neces-
sary. However, the plenum attached to the coil
casing must be installed such that its surfaces
are at least 1" from combustible construction.
A gas-fired furnace installed in a residential
garage must be installed so that the bottom of the
furnace is located a minimum of 18" from the
floor. The furnace must be located or protected
to avoid physical damage by vehicles.
HORIZONTAL INSTALLATIONS
The upflow model furnaces are approved for
horizontal installation. Installation Kit #903568 is
available for horizontal applications. The parts
may also be field supplied. The parts that are
field supplied should conform to Figures 3 and
4. NOTE: Downflow models are NOT approved
for horizontal installation.

CAUTION:
Damage to the product resulting from
failure to follow instructions or use of
unauthorized parts may void the
manufacturer's product warranty cov-
erage.
The 90+ upflow furnace can be installed hori-
zontally in an attic, basement, crawl space or
alcove. This furnace can be installed horizon-
tally to the clearances listed in Table 2 on a
platform or on the ceiling rafters. Note that the
platform and the ceiling rafters must be able to
support the weight of the furnace being installed.
It can also be suspended from a ceiling in a
basement or utility room in either a right to left
airflow or left to right airflow.
When installed horizontally, the furnace must be
raised above the surface to allow a drain trap to
hang vertically below the furnace. This will allow
for proper drainage of the condensate from the
furnace.
