2102 Blower Accessory
Installation & Operating Instructions
Note: All electrical work must conform to your local codes and
ordinances or in their absence, with National Electrical Code,
ANSI/NFPA 70. If you are not familiar with wiring codes in general,
have a competent electrician do this job.
In CANADA: CANADIAN ELECTRICAL CODE C22.1.
Danger of property damage, bodily injury or
death. Turn off electrical power supply at
disconnect switch, fuse box or service panel
before removing or working on fan.
WARNING
This accessory is operated using the factory equipped three-prong (grounding) plug and cord. When using the plug and cord, for your protection against
shock hazard, it must be plugged directly into a properly grounded three-prong receptacle.
DO NOT CUT OR REMOVE THE PRONG.
Mounting the Blower Accessory to the Furnace
1. Place the motor and blower on the heater floor, securing with four (4) screws. Attach three (3) screws to the inlet duct and one (1) screw to the
heater floor, using the existing screw holes. Align the opening in the base of the motor and blower with the opening in the furnace floor. The opening
on the side of the motor and blower should align with the opening on the heater inlet duct.
2. Attach the “HI” and “LO” speed switch to the upper left corner on the back of the heater and replace the corner bracket with the speed switch plate
using the existing mounting holes (item 7). The correct position for the fan switch is shown below. The top of the fan switch should be level with the
notch directly across the switch on the blower mounting plate.
Make sure speed switch wires (item 6) are secured with clamp (provided in the
kit) away from the combustion chamber before operating the heater.
Use the Fan Switch for Blower Settings
You must select “HI” or “LO” on the speed switch (item 8) for automatic blower operation. When the heater heats up, the fan switch is activated and
the blower will operate. When the heater cools down, the blower will turn off. The blower will not operate if the speed switch is set in the “OFF”
(center) position.
