* 5" or 6" vent connector may be required in some cases.
6. Always install furnace to operate within the furnace's intended
temperature-rise range with a duct system which has an
external static pressure within the allowable range, as speci-
fied in the "Start-Up, Adjustments, and Safety Check" section.
See furnace rating plate.
7. When a frunace is installed so that supply ducts carry air
circulated by the furnace to areas outside the space containing
the furnace, the return air shall also be handled by duct(s)
sealed to the furnace casing and terminating outside the space
containing the furnace. See "Air Ducts" section.
8. A gas-fired furnace for installation in a residential garage must
be installed as specified in the warning box in the "Location"
section.
9. The furnace is not to be used for temporary heating of
buildings or structures under construction. See page 5 caution
box.

10. These Multipoise Gas-Fired Furnaces are CSA (A.G.A. and
C.G.A.) design-certified for natural and propane gases (see
furnace rating plate) and for installation in alcoves, attics,
basements, closets, utility rooms, crawlspaces, and garages.
The furnace is factory-shipped for use with natural gas. A
CSA (A.G.A. and C.G.A.) listed gas conversion kit is required
to convert furnace for use with propane gas.
→
11. See Fig. 2 for required clearances to combustibles.
→
12. Maintain a 1-in. clearance from combustible materials to
supply air ductwork for a distance of 36 inches horizontally
from the furnace. See NFPA 90B or local code for further
requirements.
→
13. These furnaces SHALL NOT be installed directly on carpet-
ing, tile, or any other combustible material other than wood
flooring. In downflow installations, factory accessory floor
base MUST be used when installed on combustible materials
and wood flooring. Special base is not required when this
furnace is installed on manufacturer's Coil Assembly Part No.
CD5 or CK5, or when Coil Box Part No. KCAKC is used.

The Series 100/A 4–way multipoise Category I furnace is CSA
(A.G.A. and C.G.A.) design-certified for natural and propane gas
and for installation in alcoves, attics, basements, closets, utility
rooms, crawlspaces, and garages. A fan-assisted furnace is an
appliance equipped with an integral mechanical means to either
draw or force products of combustion through the combustion
chamber and/or heat exchanger. The furnace is factory-shipped for
use with natural gas. A CSA (A.G.A. and C.G.A.) listed gas
conversion kit is required to convert furnace for use with propane
gas. This furnace is not approved for installation in mobile homes,
recreational vehicles, or outdoors.
These furnaces shall not be installed directly on carpeting, tile, or
any other combustible material other than wood flooring. For
downflow installations, a factory accessory floor base must be
used when installed on combustible materials and wood flooring.

This special base is not required when this furnace is installed on
the manufacturer's coil assembly, or when the manufacturer's coil
box is used. See Figure 2 for clearance to combustible material
information.
This furnace is designed for minimum continuous return-air
temperature of 60°F db or intermittent operation down to 55°F db
such as when used with a night setback thermostat. Return-air
temperature must not exceed 85°F db. Failure to follow these
return-air limits may affect reliability of heat exchangers, motors,
and controls. (See Fig. 3.)
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before oper-
ating the furnace.
