NOTES FOR FIGURES 25 - 31
1. Heat pump
MUST
have a high pressure switch for 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 having
date codes 1601E and later do not have or require a “ZONE”
selection.
4. Outdoor Air Temperature Sensor must be attached in all dual fuel
applications.
5. Dip switch No. 1 on Thermidistat should be set in OFF position for
air conditioner installations. This is factory default.
6. Dip switch No. 1 on Thermidistat should be set in ON position for
heat pump installations.
7. Dip switch No. 2 on Thermidistat should be set in OFF position for
single-speed compressor operation. This is factory default.
8. Dip switch No. 2 on Thermidistat should be set in ON position for
two-speed compressor operation.
9. Configuration Option No. 10 “Dual Fuel Selection” must be turned
ON in all dual fuel applications.
10. NO connection should be made to the furnace HUM terminal when
using a Thermidistat.
11. Optional connection: If wire is connected, ACRDJ jumper on
furnace
control
should
be
removed
to
allow
Thermidistat/Thermostat to control outdoor unit staging.
12. Furnace must control its own stage heating operation via furnace
control algorithm.
13. The RVS Sensing terminal “L” should not be connected. This is
internally used to sense defrost operation.
14. DO NOT SELECT the “FURNACE INTERFACE” or “BALANCE
POINT” option on the two-speed heat pump control board. This is
controlled internally by the Thermidistat/Dual Fuel Thermostat.
15. Dip switch D on Dual Fuel Thermostat should be set in OFF
position for single-speed compressor operation. This is factory
default.
16. Dip switch D on Dual Fuel Thermostat should be set in ON position
for two-speed compressor operation.
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.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected
to the venting system being placed into operation could result in carbon
monoxide poisoning or death. The following steps shall be followed for
each appliance connected to the venting system being placed into
operation, while all other appliances connected to the venting system
are not in operation:
1. Seal any unused openings in venting system.
2. Inspect the venting system for proper size and horizontal pitch, as
required in the current edition of National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and other deficiencies,
which could cause an unsafe condition.
3. As far as practical, close all building doors and windows and all
doors between the space in which the appliance(s) connected to
the venting system are located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected to the
venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they are operating at maximum speed. Do
not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being
inspected into operation. Adjust the thermostat so appliance is
operating continuously.
7. Test for spillage from draft hood equipped appliances at the draft
hood relief opening after 5 minutes of main burner operation. Use
the flame of a match or candle.
8. If improper venting is observed during any of the above tests, the
venting system must be corrected in accordance with the current
edition of National Fuel Gas Code, ANSI Z223.1/NFPA 54.
9. After it has been determined that each appliance connected to the
venting system properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace dampers and any
other gas-fired burning appliance to their previous conditions of
use.
