1. Heat pump MUST have a high pressure switch for HYBRID HEATr dual fuel applications.
2. Refer to outdoor equipment Installation Instructions for additional information and setup procedure.
3. If the heat pump date code is 1501E or earlier, select the "ZONE" position on the two speed heat pump control. Heat pumps with date
code 1601E and later do not have or require a "ZONE" selection.
4. Outdoor Air Temperature Sensor must be attached in all HYBRID HEATr dual fuel applications.
5. Configure the thermostat for air conditioner installations. Refer to thermostat instructions.
6. Configure thermostat for heat pump installations. Refer to thermostat instructions.
7. Configure thermostat for single-stage compressor operation. Refer to thermostat instructions.
8. Configure thermostat for HYBRID HEATr dual fuel operation. Refer to thermostat instructions.
9. NO connection should be made to the furnace HUM terminal when using a thermostat with a 24 volt humidifier output.
10. The RVS Sensing terminal "L" should not be connected. This is used internally to sense defrost operation.
11. If thermostat has internal control of heat pump balance point, DO NOT SELECT the "FURNACE INTERFACE" or "BALANCE
POINT" option on the two- -speed heat pump control board. Refer to thermostat instructions.
12. Thermostat signals may vary. Consult thermostat installation instructions for more information.
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 DuraVentR
venting systems.
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.
