IV. HORIZONTAL VENTING
This furnace may be vented horizontally through an outside wall
when installed with 1 of the following auxiliary inducer blowers:
Tjernlund Products, Inc. Model SS1 (SS1C required in Canada)
available from: Tjernlund Products, Inc.
1601 Ninth Street
White Bear Lake, MN 55110-6795
(612) 426-2993
Fields Controls Model SWGII-5 (with a CK-60 or CK-61 timer)
available from: Fields Controls Company
2308 Airport Road
Kinston, NC 28051
(919) 522-3031
NOTE: In both cases, the 24-v wiring schematic included with
inducer is the recommended wiring setup.
The use of either inducer can create a negative pressure in the area
where furnace is located if the proper combustion-air openings are
not available. This negative pressure can lead to excessive heat
being retained in heat exchanger, coking, and fumes. Refer to
NFPA-31 Section 1.5 for proper combustion-air requirements.
CAUTION: USE METALLIC VENT PIPE ONLY!
PLASTIC VENTING MATERIALS ARE PROHIB-
ITED!
OIL BURNER
This furnace is supplied with a high-pressure atomizing retention
head type burner (for use with not heavier than grade 2 Fuel Oil).
The air tube length, from face of mounting plate to extreme face of
end cone, should be as shown in Table 3.

OIL CONNECTIONS
Complete instructions for installation of fuel oil piping will be
found in oil burner Installation Instructions included with furnace.
→
Oil line entry holes are provided in side panels and top panel. Two
holes are provided in each side panel, and elongated holes are
provided in top panel so that a 2-pipe system may be used if
desired. (See Fig. 9.)
→
A properly sized oil filter should be used with all oil burners and
should be installed as close to burner as possible. For a 2-pipe
system, a minimum capacity of 25 gph is needed.
BAROMETRIC DRAFT CONTROL
The barometric draft control shipped with furnace MUST be used
with furnace to ensure proper operation. Instructions for installing
control are packed with control. Refer to Fig. 10 for suggested
locations.
ELECTRICAL
The appliance must be installed in accordance with current
ANSI/NFPA 70 National Electrical Code, CSA C22.1 Canadian
Electrical Code Part 1, and/or local codes.
The control system depends on correct polarity of power supply.
Connect HOT wire (H) and NEUTRAL wire (N) as shown in Fig.
11.

A separate line voltage supply MUST be used with a fused
disconnect switch or HACR-type circuit breaker between main
power panel and unit. (See Fig. 11.) Disconnecting means must be
within sight from furnace.
WARNING: The unit cabinet must have an uninter-
rupted or unbroken electrical ground to minimize per-
sonal injury if an electrical fault should occur. A green
ground screw is provided in control box for this connec-
tion.
Use only copper wire for 115-v supply service to unit.
Metallic conduit (where required/used) may terminate at side panel
of unit. It is not necessary to extend conduit inside unit from side
panel to control box.
When replacing any original furnace wiring, use only 105°C No.
16 AWG copper wire.
Instructions for wiring thermostat (field supplied) are packed in
thermostat box. Make thermostat connections as shown in Fig. 11
at 24-v terminal board on control box.
When installing optional accessories to this appliance, follow
manufacturer's Installation Instructions included with accessory.
Other than wiring for thermostat, wire with a minimum of type "T"
insulation (63°F rise) must be used for accessories.
→
Two 1/4-in. quick-connect terminals marked EAC and N5 are
provided for electronic air cleaner (EAC) connection. (See Fig.
11.) These terminals are energized with 115v (0.5-amp maximum)
during blower motor operation.
→
Two 1/4-in. quick-connect terminals marked HUM and N6 are
provided for 115-v humidifier connection. (See Fig. 11.) These
terminals are energized with 115v (0.5-amp maximum) during any
call for heat.
It is NECESSARY THAT ALL FURNACES BE EQUIPPED
WITH A FILTER.
A filter and external filter rack are provided as standard equipment
with this furnace. The assembly and installation of filter rack is
described below and shown in Fig. 1.
WARNING: Never operate unit without a filter or with
filter access door removed. Failure to adhere to this
warning could lead to a hazardous condition which could
lead to equipment damage and bodily harm.
Filter rack is made up of 4 pieces: a top and bottom (which are the
same) and the rear and access panels (which are the same).
I. FILTER RACK INSTALLED ON SIDE OF FURNACE
Filter rack may be mounted on either side of furnace. Install as
follows:
1. Using corner indentations as a guide, cut out selected side
duct return opening. (See Fig. 9.)
→
2. Clip filter rack pieces together as shown in Fig. 1. Use the
shorter 2 rear/access panels. Discard longer pair.
→
3. Place flange of filter rack bottom piece against side panel of
furnace, resting on top of flange of base panel. Align flange
of filter rack rear panel flush with back of furnace. The
frame should be centered over knock-out opening.
→
4. Hold filter rack against unit making sure filter rack is
square. Drill mounting holes in side of unit located accord-
ing to clearance holes in filter rack top, bottom, and rear
panels. DO NOT SCREW ACCESS PANEL IN PLACE.
5. Fasten return-air duct to filter rack.
