Fig. 38 – Thermostat Wiring Diagrams for Single Stage Furnace 
with Single-Speed A/C & Heat Pump
Notes for thermostat wiring diagrams:
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  dual fuel operation. Refer to thermostat
instructions.
5. Heat  pump  MUST  have  a  high-pressure  switch  for  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
utilizing the thermostat’s 24-volt humidifier output.
8. Thermostat terminal connection order on furnace control may vary-
reference furnace control labeling for designations
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 manufacturers 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
manufacturers  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.

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
WITH THE EXTERNAL VENT TRAP KIT FOR LAYING OUT
THE  VENTING  SYSTEM  AND  THE  DRAIN  SYSTEM.  The
instructions  included  with  this  furnace  DO  NOT  APPLY  to  vent
systems that are located below the furnace.
