This fan does not need regular maintenance, however
periodic cleaning is required. Check the area under the

at least once a month during the operating season.
Should this fan require servicing, the power supply must
be disconnected.
The FK-24 comes with the electrical cord attached.
1. Slide fan assembly from the left side into the fire-
place opening, line up mounting holes with screw
studs on back of fireplace and fasten with #10-24
hex nuts.
2. Install thermal sensor on bottom of firebox using
#10-24 hex nuts.
3. (Option A) - Place electronic fan speed control box
on bottom of fireplace base, lining up mounting holes
with screw studs. Fasten fan speed control box with
#10-24 hex nuts.
(Option B) - The speed control can be installed in an
electrical box at normal wall switch height for conve-
nient access.
4. The power supply may be connected in 2 ways:
Method A - route the 6' (1.8m) lead fitted to the unit
to a conveniently located wall socket.
Method B - If the EB-1 receptacle box (Pt. #ZA1200)
was correctly connected when the unit was installed,
the fan lead can be directly plugged into the EB-1
plug socket.
5. Whether wiring directly to the fan junction box, (Op-
tion A) or into the EB-1 (Option B), first ensure cable
is secured using box connector.
The fireplace, when installed must be electrically
connected and grounded in accordance with local
codes or, in the absence of local codes, with the
current CSA C22.1 Canadian Electrical Code or for
US installations, follow local codes and the National
Electrical Code, ANSI/NFPA No. 70.
Hard (Direct) Wire Hook-Up
First connect the ground wire to the ground stud located
on the base of either box. Black wire from supply
should connect to the variable speed switch. Alternate
speed switch wire connects to temperature sensor. Al-
ternate lead from sensor connects to fan. Alternate fan
lead connects back to the white supply wire. (Fig. 23)
Any electrical rewiring of this fan must be
completed by a qualified electrician.
Turn off all power before hook-up.
