installing the honeYWell
fan/liMit control
1. After attaching the warm air sheet metal plenum to the
furnace, using the fan/limit control white mounting flange
as a template, place it on the top edge of the furnace
casing above the fire door so that the holes in the furnace
casing and the flange are aligned with each other. Attach
the screws to secure the flange. (See Fig. 7)
2. Using the flange as a template, mark the center of the
large hole and the two smaller holes, remove the bracket
and drill a 7/8" hole and two 1/8" holes in the sheet metal
plenum.
3. Replace the flange and reattach it with the mounting
screws.
4. Mount the fan/limit control ridged bracket (furnished with
the fan/limit control) with two 1/2 x 7 sheet metal screws.
5. Insert the fan/limit control into the bracket. Align so that it
is straight. Tighten setscrew to secure control.
electric Wiring
All electrical wiring must be done in accordance with the National
Electrical Code and the code in effect in your area. The electric
power supply to the furnace must be through a circuit protector
device switch located near the furnace. Use No.14 or heavier
wire in circuit. All furnaces covered by this manual operate on 115
Volts, 60 Cycle, 1-Phase Alternating Current with a 15 amp Circuit
Protector device.
Turn off electric power at circuit protector device before making
any line voltage connections.
Wiring the furnace
On the front of the furnace, next to the wood feed door, is the end
of the wiring harness coming from the blower motor. Remove the
lock-nut on the cable connector and place the 4" square box the
furnished wiring harness over cable connector and replace the
lock-nut. Secure the square box to the furnace with two sheet
metal screws.
Connect the 34" long conduit to the fan/limit switch previously
mounted in the warm air plenum.
Connect the main power supply to the 4" square box. This must be
through a 15 amp circuit protector device. No lighter than No.14
wire may be used in the furnace electric power supply circuit. Wire
blower motor, fan/limit and transformer per Fig. 9 page 14.
This furnace is not approved for use with aluminum wire.
Warning
caution
ash Pan handles
Install ash pan handle as follows:
1. Remove pull handle, 10- 24 x 2" screws from plastic bag.
2. Insert 2 No.10 -24 x 2" screws through pull handle into thread-
ed holes on ash pan and tighten.
3. Remove tapered handle from plastic bag and screw to steel
handle.
Mounting the therMostat
The thermostat must be mounted on an interior centrally located
wall away from direct sunlight and drafts and approximately 5 feet
above the floor.
1. Run 2 conductor thermostat wire (4 wire if you intend to add air
conditioning) from the damper control unit to the thermostat.
Leveling of the thermostat is not necessary as it is digital.
2. Connect the wires as outlined on page 14.
installing air conditioning coil
The coil should always be installed in the warm air plenum. The
metal condensate pan should be at least 2 inches above the
fan limit control probe so that the heated air flow direction is not
changed. The air flow needed for gravity operation in the event
of an electric power or furnace fan failure must not be restricted.
It is recommended that you install manual dampers along side of
the condensate pan that can be manually removed or opened for
winter operation.
