WARNING:

**These speeds can only be run with heater off, for cooling/ventilation purposes only.

OPERATING OPTIONS

The furnace is shipped from the factory in a “Standard Heating Mode” (all switches in the Down position). When the thermostat calls for heat, the automatic controls will be activated and the furnace turns “ON”.

The blower will run at low speed or higher speed (as selected by

SPEEDSELECTORswitch).

HIGH

LOW

SPEEDSELECTOR

As the furnace heats up, it automatically switches to a medium speed when additional elements are activated by the electronic control, if it was initially set to run at low speed. The timing of this blower speed change will depend on whether COLD orMILD is selected on theSEASON SELECT switch.

You may, however, change from the Standard Heating Mode by using the controls built into your furnace.

INSTALLATION NOTES

1.COLD AIR RETURN

The duct can be attached to either side, rear or the bottom of the furnace.

For side return there are four 1½” (38 mm) knockouts which can be removed and used as an outline for cutting a 18” x 18” (457 mm x 457 mm) return air opening in the furnace left or right side. Mount the filter frame to the furnace over the opening with the open side of the frame facing front. Then attach the 19” x 19” (483 mm x 483 mm) air duct to the flanges on the filter frame. For bottom mounting, remove the screws holding the bottom plate to the furnace, discard the bottom plate and attach the filter frame to the bottom flanges with the open side of the frame facing front.

3.CONNECTING AND ADJUSTING THE LOW VOLTAGE THERMOSTAT

(Use only class 1 wires inside furnace compartments.) Attach thermostat wires to the low voltage terminal connections located on the printed circuit board inside the furnace. Follow the diagrams supplied with the thermostat. As a general guide, remember that the R & W terminals control single stage heating; the R & Y terminals control cooling. Single stage cooling uses “Y/Y2” as first and only stage.

Two-stagecooling uses “Y1” as first stage and “Y/Y2” as second stage. Make sure the thermostat is levelled on the wall and in appropriate location as per instructions supplied with the thermostat.

2.ELECTRICAL WIRING - POWER SUPPLY

The furnaces are completely factory wired. From a separate breaker, a two-wireplus ground supply wire is required. The ground conductor must be firmly attached to the ground lug in the furnace and the supply wires to the terminal block in the furnace.

NOTE: If a FK120 kit will be used to supply an air cleaner and/or humidifier, a third (neutral) conductor must be brought into the furnace.

! WARNING

For all installations, we only recommend appropriate gauge good quality copper wire(s). However, it is the electrician’s responsibility to ensure that the wiring and connections are compliant to the latest editions of the Canadian Electrical Code and local codes.

CAUTION

Before turning the furnace on, the heat anticipator in the thermostat must be properly set to prevent its failure and to assure comfortable, economical heating.

Because each installation is different an accurate reading of the current draw should be made with an AC meter. Set the meter at a 2 A range.

A.Set the anticipator at its highest setting.

B.Disconnect the “W1” thermostat wire from the furnace low voltage terminal connections.

C.Connect the AC meter between the “W1” terminal on the board and the loose “W1” wire.

D.Turn the thermostat up to start the furnace and allow it to run, with all elements on, for three or four minutes.

E.Read the current draw on the meter and reset the anticipator to match the meter reading.

FOR USE IN MOBILE HOMES

D Series furnaces models 21D10, 21D15, 21D18 and 21D20 are certified for “L” -shapeand“T”-shapeshallow duct installation with modelFSB-1sub-basein downflow applications when the supply air ducts pass through the floor of the structure. Recommended size of a floor opening: 14¼” x 14¼” (362 mm x 362 mm). The duct system must be designed so that the external static pressure of the system does not exceed the maximum external static pressure of 0.50” W.C. (125 Pa).

USING OPTIONAL EQUIPMENT

1.TWO-STAGEOR OUTDOOR THERMOSTAT

(The SEASON SELECT switch must be in theMILD position). Follow the directions supplied with thetwo-stageor outdoor thermostat in conjunction with the furnace wiring diagram.

2.AIR CONDITIONING

Your furnace is equipped with all the controls required for the addition of air conditioning (except the heat-coolthermostat). 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-conditioningfield wiring connections are shown in the following diagram:

3.ELECTRONIC AIR CLEANERS AND/OR POWERED 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.INTERLOCK CONNECTION

When the electric furnace is used in combination with another device (as for example, a wood burning furnace), it is recommended to perform the connection by referring to the wiring diagram below. The burning furnace thermostat will then turn automatically on 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 thermalcut-outwhich is set to open at 160°F (71°C). If it opens, the element will bede-energizeduntil thecut-outresets itself. In addition to that, there are 2 manual reset thermalcut-outsthatopen at 200°F (93°C). If any of them open, a front panel needs to be removed so thecut-outcan be manually reset.

! WARNING

Cut 240 V supply before removing the front panel!

The reason for the failure should be investigated before re-startingthe furnace. The limit usually opens when airflow is reduced because of blocked ductwork or very dirty filters.

TROUBLESHOOTING

The first step in identifying an operational problem is to determine whether the fault is in the furnace or in the thermostat and/or its connecting wiring.

To help make this determination, the furnace is equipped with a “Thermostat ON” diagnostic light. If the light is “ON”, it indicates the thermostat has closed and is calling for heat; the blower should be running. If the light is “OFF”, the furnace should not be operating.

1.If the furnace will not start:

Turn the thermostat to its highest setting. If the light goes on, the thermostat has closed, so the fault is in the furnace. If the light does not go on, the thermostat or its connecting wiring is the problem.

2.If the furnace will not turn off:

Turn the thermostat to its lowest setting. If the light goes off and the furnace continues to run, the thermostat has opened properly and the fault is in the furnace. If the light stays on, the fault is in the thermostat or its connecting wiring.

After the fault area is isolated by use of the diagnostic light, a check of the following components can be made more efficiently.

PROBLEM

POSSIBLE DEFECTIVE PARTS OR COMPONENTS

 

 

1. The furnace will not turn on

• Thermostat

 

• Circuit breaker or fuse is open

 

• Motor or capacitor

 

SPEED SELECTOR switch (open contact)

 

• Electronic control

 

• Transformer

 

 

2. Motor runs continuously

• Thermostat wires incorrectly attached to furnace

 

 

3. Elements on, but motor does not run

• Motor or capacitor

SPEED SELECTOR switch (open contact)

 

 

• Electronic control

4. Motor going on and off in short cycles

• Heat anticipator in thermostat incorrectly set

(or in too long cycles)

or may be defective

 

 

5. Must set thermostat much higher (or lower)

• Thermostat is not leveled or out of calibration

than the desired house temperature

 

 

 

6. Not enough heat

• One or more defective elements or relays

 

SEASON SELECT switch inMILD position

 

• Safety limits opening because duct obstruction

 

or dirty filters are restricting air flow

 

• Defective or incorrectly wired two-stage

 

or outdoor thermostat

 

• Lack of enough cold air returns in house

 

 

7. Two-stageor outdoor thermostat not operating properly
