NOTES FOR THERMOSTAT WIRING DIAGRAMS
1. Heat pump MUST have a high pressure switch for HYBRID
HEAT
®
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
HEAT
®
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 HEAT
®
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.
VENTING
The furnace shall be connected to a listed factory built chimney or vent,
or a clay-tile lined masonry or concrete chimney. Venting into an unlined
masonry chimney or concrete chimney is prohibited.
When an existing Category I furnace is removed or replaced, the original
venting system may no longer be sized to properly vent the attached
appliances. An improperly sized Category I venting system could cause
the formation of condensate in the furnace and vent, leakage of
condensate and combustion products, and spillage of combustion
products into the living space.
Vent system or vent connectors may need to be resized. Vent systems or
vent connectors, must be sized to approach minimum size as determined
using appropriate table found in the NFGC.
GENERAL VENTING REQUIREMENTS
Follow all safety codes for proper vent sizing and installation
requirements, including local building codes, the current edition of
National Fuel Gas Code ANSI Z223.1/NFPA 54 (NFGC), Parts 12 and
13, the local building codes, and furnace and vent manufacturers’
instructions.
These furnaces are design-certified as Category I furnaces in accordance
with current edition of ANSI Z21.47/CSA 2.3 and operate with a
non-positive vent static pressure to minimize the potential for vent gas
leakage. Category I furnaces operate with a flue loss not less than 17
percent to minimize the potential for condensation in the venting system.
These furnaces are approved for common venting and multistory venting
with other fan assisted or draft hood equipped appliances in accordance
with the NFGC, the local building codes, and furnace and vent
manufacturers’ instructions.
The following information and warning must be considered in addition
to the requirements defined in the NFGC.
1. If a vent (common or dedicated) becomes blocked, the furnace will
be shut off by the draft safeguard switch located on the vent elbow.
2. Do not vent this Category I furnace into a single-wall dedicated or
common vent. The dedicated or common vent is considered to be
the vertical portion of the vent system that terminates outdoors.
3. Vent connectors serving Category I furnaces shall not be connected
into any portion of a mechanical draft system operating under
positive pressure.
4. Do not vent this appliance with any solid fuel burning appliance.
5. Category I furnaces must be vented vertically or nearly vertically
unless equipped with a listed power venter.
6. Do not vent this appliance into an unlined masonry chimney. (Refer
).

MASONRY CHIMNEY REQUIREMENTS
NOTE:
These furnaces are CSA design-certified for use in exterior
tile-lined masonry chimneys with a factory accessory Chimney Adapter
Kit. Refer to the furnace rating plate for correct kit usage. The Chimney
Adapter Kits are for use with ONLY furnaces having a Chimney Adapter
Kit numbers marked on the furnace rating plate.
If a clay tile-lined masonry chimney is being used and it is exposed to
the outdoors below the roof line, relining might be required. Chimneys
shall conform to the Standard for Chimneys, Fireplaces, Vents, and Solid
Fuel Burning Appliances current edition of ANSI/NFPA 211 and must
be in good condition.
