Notes for Thermostat Drawings:
1. Thermostat output signals may vary. Consult thermostat installation
instructions for more information.
2. Refer to outdoor equipment Installation Instructions for additional
information and setup procedure.
3. Configure the thermostat for air conditioner installations. Refer to
thermostat instructions.
4. Configure thermostat for HYBRID HEAT® dual fuel operation.
Refer to thermostat instructions.
5. Heat pump MUST have a high pressure switch for HYBRID
HEAT® dual fuel applications.
6. For Single-stage AC or HP, configure thermostat for single-stage
compressor operation. Refer to thermostat instructions.
7. NO connection should be made to the furnace HUM terminal when
using a thermostat with a 24 volt humidifier output.
8. For Two-Stage AC or HP, thermostat may be configured for
two-stage compressor operation, allowing the thermostat to control
staging, or thermostat may be configured for single stage operation,
allowing furnace control to control staging. Refer to note 9 and
thermostat instructions.
9. For Two-stage outdoor equipment, connection is Optional - See
Cooling sequence of operations (adaptive mode) for additional
information. If two-stage HP/cooling thermostat is connected to Y1
and Y/Y2 on Modulating or Two-stage furnace control board,
Cooling Thermostat Type (Ctt) (setting on furnace control) should
be set to “2St” to allow thermostat to control outdoor unit staging.
10. For Single-stage outdoor equipment, connect thermostat HP or AC
output to Y/Y2 of furnace control.
11. Configure Dehumidify function to remove 24 VAC from Dehum
terminal on a demand to dehumidify. Consult thermostat
installation instructions for more information.
12. Thermostat terminal connection order on furnace control may vary-
reference furnace control labeling for designations.
13. Field installed jumper required for InteliSense™ installations using
single-stage AC or HP.
VENTING
NOTE: Planning for the venting system should be done in conjunction
with planning for the ductwork, drainage, and furnace accessories, such
as air cleaners and humidifiers. Begin assembling the venting system
AFTER the furnace is set in place in the required orientation.
Venting for this furnace shall follow all Local codes for Category IV
venting systems. This furnace is CSA approved for venting with
PVC/ABS DWV venting systems. This furnace is also CSA approved
for venting with M&G DuraVentRPolyProR or Centrotherm InnoFlueR
polypropylene venting systems using single wall straight and flex, and
required fittings (elbows, reducers, increasers, connectors, adapters)
only.
NOTE: THESE INSTRUCTIONS DO NOT CONTAIN DETAILED
INSTALLATION INSTRUCTIONS FOR POLYPROPYLENE
VENTING SYSTEMS. Refer to the polypropylene venting system
manufacturer’s installation instructions for the polypropylene venting
system installation.
NOTE: When using polypropylene venting systems, all venting
materials used, including the vent terminations, must be from the same
manufacturer.
Special Venting Requirements for Installations in
Canada
Installation in Canada must conform to the requirements of CSA B149
code. Vent systems must be composed of pipe, fittings, cements, and
primers listed to ULC S636. The special vent fittings, accessory
concentric vent termination kits, (KGAVT0701CVT or
KGAVT0801CVT) and accessory external drain trap available from the
furnace manufacturer have been certified to ULC S636 for use with
those Royal Pipe and IPEX PVC vent components which have been
certified to this standard. In Canada, the primer and cement must be of
the same manufacturer as the vent system – GVS-65 Primer (Purple) for
Royal Pipe or IPEX System 636, PVC/CPVC Primer, Purple Violet for
Flue Gas Venting and GVS-65 PVC Solvent Cement for Royal Pipe or
IPEX System 636
(1)
t, PVC Cement for Flue Gas Venting, rated Class
IIA, 65 deg C. must be used with this venting system - do not mix
primers and cements from one manufacturer with a vent system from a
different manufacturer. Follow the manufacturer’s instructions in the use
of primer and cement and never use primer or cement beyond its
expiration date.
The safe operation, as defined by ULC S636, of the vent system is based
on following these installation instructions, the vent system
manufacturer’s installation instructions, and proper use of primer and
cement. All fire stop and roof flashing used with this system must be UL
listed material. Acceptability under Canadian standard CAN/CSA B149
is dependent upon full compliance with all installation instructions.
Under this standard, it is recommended that the vent system be checked
once a year by qualified service personnel.
The authority having jurisdiction (gas inspection authority, municipal
building department, fire department, etc.) should be consulted before
installation to determine the need to obtain a permit.

NOTICE
!
OPTIONAL VENTING BELOW THE FURNACE
The venting system may be positioned below the furnace ONLY IF the
factory accessory External Vent Trap Kit is used. The External Vent
Trap Kit is only approved for PVC/ABS DWV venting systems.
CAREFULLY FOLLOW THE INSTRUCTIONS PROVIDED

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the instructions outlined below for each appliance
being placed into operation could result in carbon monoxide poisoning
or death.
For all venting configurations for this appliance and other gas
appliances placed into operation for this structure, provisions for
adequate combustion, ventilation, and dilution air must be provided in
accordance with:
USA Installations: Section 9.3 current edition of NFPA 54/ANSI
Z223.1, Air for Combustion and Ventilation and applicable provisions
