Never allow the products of combustion, including carbon
monoxide, to enter the return ductwork or circulation air
supply.
MASONRY CHIMNEYS
Possibility of property damage, personal injury or death
damaging condensation can occur inside masonry chimneys
when a single fan-assisted Category I appliance (80% AFUE
Furnace) is vented without adequate dilution air. Do not
connect an 80% furnace to a masonry Chimney unless
the furnace is common vented with a draft hood equipped
appliance or the chimney is lined with a metal liner or Type
B metal vent. All installations using masonry chimneys must
be sized in accordance with the appropriate venting tables. If
an 80% furnace is common vented with a draft hood equipped
appliance, the potential for condensation damage may still
exist with extremely cold conditions, long vent connectors,
exterior chimneys, or any combination of these conditions.
The risk of condensation damage is best avoided by using
masonry chimneys as a pathway for properly sized metal liner
or Type B metal vent.
Masonry Chimney Termination
A masonry chimney used as a vent for gas fired equipment
must extend at least three feet above the highest point
where it passes through the roof. It must extend at least two
feet higher than any portion of a building within a horizontal
distance of 10 feet. In addition, the chimney must terminate
at least 3 feet above any forced air inlet located within 10
feet. The chimney must extend at least five feet above the
highest connected equipment draft hood outlet or flue collar.
ELECTRICAL CONNECTIONS
HIGH VOLTAGE
To avoid risk of electrical shock, wiring to
the unit must be polarized and grounded.
HIGH VOLTAGE
To avoid personal injury or death due to
electrical shock, disconnect electrical power
before servicing or changing any electrical
wiring.
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation after servicing.

WARNING
CAUTION
HIGH VOLTAGE
To avoid risk of injury, electrical shock
or death, the furnace must be electrically
grounded in accordance with local codes or
in their absence, with the latest edition of the
National Electric Code.
Edges of sheet metal holes may be sharp. Use gloves as a
precaution when removing plugs.
Wiring Harness
The wiring harness is an integral part of this furnace. Field
alteration to comply with electrical codes should not be
required. Wires are color coded for identification purposes.
Refer to the wiring diagram for wire routings. If any of the
original wire as supplied with the furnace must be replaced,
it must be replaced with wiring material having a temperature
rating of at least 105°C. Any replacement wiring must be a
copper conductor.
115 Volt Line Connections
Before proceeding with electrical connections, ensure that
the supply voltage, frequency, and phase correspond to
that specified on the unit rating plate. Power supply to the
furnace must be NEC Class 1, and must comply with all
applicable codes. The furnace must be electrically grounded
in accordance with local codes or, in their absence, with the
latest edition of The National Electric Code, ANSI NFPA 70
and/or The Canadian Electric Code CSA C22.1.
Use a separate fused branch electrical circuit containing
properly sized wire, and fuse or circuit breaker. The fuse
or circuit breaker must be sized in accordance with the
maximum overcurrent protection specified on the unit rating
plate. An electrical disconnect must be provided at the
furnace location.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit's blower door.
Line polarity must be observed when making field
connections. Line voltage connections can be made through
either the right or left side panel. The furnace is shipped
configured for a right side electrical connection with the
junction box located inside the burner compartment (blower
compartment for downflows). To make electrical connections
through the opposite side of the furnace, the junction box
must be relocated to the other side of the burner (or blower)
compartment prior to making electrical connections. To
relocate the junction box, follow the steps shown below.
NOTE: Wire routing must not to interfere with
circulator blower operation, filter removal, or
routine maintenance.
