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.
WARNING: 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.
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 heater 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. 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 are secured with clamp (provided
in the kit) away from the combustion chamber before
operating the heater.

OPERATION
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.
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.
