instructions thoroughly and follow all warnings or cautions
include in literature and attached to the unit. Consult local
building codes, the current editions of the National Fuel Gas
Code (NFGC) NFPA 54/ANSI Z223.1 and the National
Electrical Code (NEC) NFPA 70.
In Canada, refer to the current editions of the National Standards
of Canada CAN/CSA--B149.1 and .2 Natural Gas and Propane
Installation Codes, and Canadian Electrical Code CSA C22.1
Recognize safety information. This is the safety--alert symbol
.
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand the signal words
DANGER
,
WARNING
, and
CAUTION
. These words are used with the safety--alert symbol.
DANGER
identifies the most serious hazards which
will
result in
severe personal injury or death.
WARNING
signifies hazards
which
could
result in personal injury or death.
CAUTION
is
used to identify unsafe practices which
may
result in minor
personal injury or product and property damage.
NOTE

to highlight suggestions which
will
result in enhanced
installation, reliability, or operation.
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing, safety glasses and
gloves when handling parts and servicing furnaces.
CAUTION
!
1. Use only with type of gas approved for this furnace. Refer
to the furnace rating plate.
2. Install this furnace only in a location and position as
specified in the “Location” section of these instructions.
3. Provide adequate combustion and ventilation air to the
furnace space as specified in “Air for Combustion and
Ventilation” section.
4. Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system only, as
specified inthe “Venting” section of these instructions.
5. Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically for
the detection of leaks to check all connections, as specified
in the “Gas Piping” section.
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 specified in the “Start--Up, Adjustments, and Safety
Check” section. See furnace rating plate.
7. When a furnace 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 may be used for construction heat provided
that the furnace installation and operation complies with
the first CAUTION in the LOCATION section of these
instructions.
10. These Multipoise Gas--Fired Furnaces are CSA (formerly
A.G.A. and C.G.A). design--certified for use with 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 listed
accessory gas conversion kit is required to convert furnace
for use with propane gas.
11. See Fig. 2 for required clearances to combustible
construction.
12. Maintain a 1--in. (25 mm) clearance from combustible
materials to supply air ductwork for a distance of 36
inches (914 mm) horizontally from the furnace. See NFPA
90B or local code for further requirements.
13. These furnaces SHALL NOT be installed directly on
carpeting, 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. CAR, CAP,
CNRV, and CNPV, or when Coil Box Part No. KCAKC is
used. See Fig. 2 for clearance to combustible construction
information.
INTRODUCTION
Series 100/A 4--way multipoise Category I fan--assisted furnace is
CSA design--certified. A Category I 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.
This furnace is not approved for installation in mobile homes,
recreational vehicles, or outdoors. This furnace is designed for
minimum continuous return--air temperature of 60
_
F (16
_
C)db
or intermittent operation down to 55
_
F (13
_
C) db such as when
used with a night setback thermostat. Return--air temperature
must not exceed 85
_
F (29
_
C) db. Failure to follow these
return--air temperature 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
operating the furnace.
