USING OPTIONAL EQUIPMENT
1. TWO-STAGE OR OUTDOOR THERMOSTAT
(The
"Season Select"
switch must be in the "Mild" position).
Follow the directions supplied with the two-stage or outdoor
thermostat in conjunction with the furnace wiring diagram.
When used, the furnace will supply heat as follows:
2. AIR CONDITIONING
Your furnace is equipped with all the controls required for the
addition of air conditioning (except the heat-cool thermostat).
The evaporator coil may be installed by a local contractor in
sheet metal plenum of his own manufacture. The coil should be
located: Centered over the "chimney" of the furnace 4" (102
mm) to 6" (152 mm) above the top of the furnace.
Make sure no air is allowed to bypass the cooling coil during
cooling operation. If the discharge opening is a great deal larger
than the coil, and the ductwork is correspondingly larger than
the coil, you may want to use a bypass damper for heating. The
damper would be closed in summer, directing all air flow
through the coil. In winter the damper would be open to allow
air to bypass the coil.
Typical air-conditioning field wiring connections are shown in
the following diagram:

Slow Response Sequence
Element 1 - Heat on instantly
Blower on after 3 seconds delay
Elements 3 and 5 after 1 minute delay Elements 3 and 5 after 10 seconds delay
Element 2 after 2 minutes delay
Elements 4 and 6 after 3-minute delay Elements 4 and 6 after 30 seconds delay
NOTE: Elements 4, 5 and 6 only where applicable.
3. ELECTRONIC
AIR
FURNACE HUMIDIFIERS
These units operate at 120 V. Your 240 V furnace is designed
so that Model FK120 adaptor kit can be mounted inside the
furnace to supply the required 120 V. Instructions for mounting
and wiring are included with the kit.
4. WOOD ELECTRIC COMBINATION
When the electric furnace is used in combination with a wood
burning furnace, connect the thermostat of the wood burning
furnace across LOW VOLTAGE TERMINALS R and G. The
thermostat in the wood burning furnace will then turn on
automatically the blower in the electric furnace.
MAINTENANCE
MOTOR: The motor is lubricated for life and needs no oiling.
FILTERS: Size is 20" x 20" x 1" (508 mm x 508 mm x 25 mm).
Should be inspected and replaced when dirty.
Ordinarily replacement is required twice per heating
season and, perhaps, a third time if continuous
blower operation is used.
NOTE: Each element has an automatic reset thermal
cut-out which is set to open at 160°F (71°C). If it opens,
the element will be de-energized until the cut-out resets
itself. In addition to that, there are 2 manual reset thermal
cut-outs that
a front panel needs to be removed so the cut-out can be
manually reset.
Cut 240 V supply before removing the front panel!
The reason for the failure should be investigated before
re-starting the furnace.
airflow is reduced because of blocked ductwork or very
dirty filters.
