GENERAL INFORMATION
WARNING
!
WHEN THIS FURNACE IS INSTALLED IN A RESIDENTIAL
GARAGE, IT MUST BE INSTALLED SO THE BURNERS
AND IGNITION SOURCE ARE LOCATED NO LESS THAN
18 INCHES [450MM] ABOVE THE FLOOR . THIS IS TO
PREVENT THE RISK OF IGNITING FLAMMABLE VAPORS
WHICH MAY BE PRESENT IN A GARAGE . ALSO, THE
FURNACE MUST BE LOCATED OR PROTECTED TO
AVOID PHYSICAL DAMAGE BY VEHICLES . FAILURE TO
FOLLOW THESE WARNINGS CAN CAUSE A FIRE OR
EXPLOSION, RESULTING IN PROPERTY DAMAGE, PER-
SONAL INJURY OR DEATH .
1 . IMPORTANT: If using a cooling evaporator coil with this fur-
nace, be sure the air passes over the heat exchanger before
passing over the cooling coil . The cooled air passing over the
warm ambient air inside the heat exchanger tubes can cause
condensation inside the tubes resulting in corrosion and even-
tual failure . An auxiliary drain pan should extend under any
evaporator coil installed with the furnace .
If there are manual dampers, they must be equipped to prevent
heating or cooling operation unless the damper is in the full heat
or cool position .
2 . NOTE: This furnace is shipped with heat exchanger support
brackets installed under the back of the heat exchanger . These
may be removed before installation, but it is not required .
3 . IMPORTANT: This furnace is not approved or recommended
for installation on its back, with access doors facing upwards.
4 . This furnace is suitable for installation in buildings constructed
on-site . This heating unit should be centralized with respect to
the heat distribution system as much as practicable .
5 . NOTE: These furnaces are approved for installation in attics,
as well as alcoves, utility rooms, closets and crawlspaces .
6 . IMPORTANT: Support this unit when installed. For attic or
crawl space installation, horizontal furnaces may be installed
on combustible wood flooring or by using support brackets.
See Figure 3.
7 . IMPORTANT: If installing in a utility room, be sure the door is
wide enough to:
a. allow the largest part of the furnace to pass; or
b. allow any other appliance (such as a water heater) to pass.
8 . IMPORTANT: This furnace is shipped with a blower motor
support bracket. This bracket must be removed before oper-
ating furnace. Remove (2) screws from front of blower and
slide bracket off motor shaft.

WARNING
!
THIS FURNACE IS NOT APPROVED OR RECOMMENDED
FOR INSTALLATION ON ITS BACK, WITH ACCESS
DOORS FACING UPWARDS .
SITE SELECTION
1 . Select a site in the building near the center of the pro-
posed, or existing, duct system .
2 . Give consideration to the vent system piping when se-
lecting the furnace location . Be sure the venting sys-
tem can get from the furnace to the termination with
minimal length and elbows .
3 . Locate the furnace near the existing gas piping . Or, if
running a new gas line, locate the furnace to minimize
the length and elbows in the gas piping . See Figure 3 .
4 . Locate the furnace to maintain proper clearance to
combustibles as shown in following Figure 4 .
WARNING
!
DO NOT LIFT THE UNIT BY THE HEAT EXCHANGER
TUBES . DOING SO CAN DAMAGE THE HEAT EX-
CHANGER ASSEMBLY .
CLEARANCE – ACCESSIBILITY
The design of forced air furnaces with input ratings as
listed in the tables under Figure 4 are to combustible ma-
terials shown in inches .
See name/rating plate and clearance label for specific
model number and clearance information .
Service clearance of at least 24 inches (61 cm) is recom-
mended in front of all furnaces .
NOTE: Use recommended 24" (61 cm) clearance if ac-
cessibility clearances are greater than fire protection clear-
ances .
ACCESSIBILITY CLEARANCES, WHERE GREATER, MUST
TAKE PRECEDENCE OVER FIRE PROTECTION CLEAR-
ANCES .
