tion of leaks to check all connections, as specified in the "Gas
Piping" section.
6. Always install lilrnace to operate within the limlace's intended
temperature-rise
range with a duct system which
has an
external static pressure within the allowable range, as speci-
lied in the "Start-Up, Adjustments, and Salety Check" section.
See furnace rating plate.
7. When a lklrnace is installed so that supply ducts carry air
circulated by the luruace to areas outside the space containing
the luruace, the return air shall also be handled by duct(s)
sealed to the Rirnace casing and terminating outside the space
containing the furnace. See "Air Ducts" section.

ff_r use with natural and
propane gases (see Rirnace rating plate) and liar installation in
alcoves, attics, basements, closets, utility rooms, crawlspaces,
and garages.
The Rirnace is factory-shipped
liar use with
natural gas. A CSA listed gas conversion
kit is required to
convert limmce liar use with propane gas.
11. See Fig. 2 lot required clearances to combustible construction.
12. Maintain a 1-in. clearance
from combustible
materials
to
supply air ductwork lot a distance of 36 inches horizontally
li"om the furnace. See NFPA 90B or local code liar lurther
requirements.
13. These l_.lrnaces SHALL NOT be installed directly on carpet-
ing, tile, or any other combustible
material other than wood
flooring. In downflow
installations,
factory accesso U floor
base MUST be used when installed on combustible materials
and wood flooring. Special base is not required when this
lurnace is installed on manulhcturer's
Coil Assembly Part No.
CD5 or CK5, or when Coil Box Part No. KCAKC is used. See
Fig. 2 l_}l* c learance to combustible construction

iNTRODUCTiON
Series 120/C 4 way nmltipoise Category I lau-assisted ll.ll'nace is
CSA design-certified.
A Category I lau-assisted
furnace is an
appliance equipped with an integral mechanical means to either
draw or lorce products of combustion
through the combustion
chamber and/or heat exchanger. The furnace is factou-shipped
lot
use with natural gas. This furnace is not approved lor installation
in mobile homes, recreational vehicles, or outdoors.
This l_lrnace is designed
l_)r minimum
continuous
return-air
temperature of 60°F db or intermittent operadou down to 55°F db
such as when used with a night setback daermostat. Return-air
temperature
must not exceed 85°F db. Failure to l_fllow these
return-air temperature limits may aflcct reliability of heat exchang-
ers, motors, and controls. (See Fig. 3.)
For accessory installation details, reler to the applicable instruction
literature.
NOTE:
Remove all shipping brackets and materials belom oper-
ating the l_rnace.
