activation of the blower, when desired and blower speed control (see
Blower Operation on Page 8).
If you encounter any problems, need clarification of these instructions or
are not qualified to properly install this kit, contact your local distributor
or dealer.
Read this instruction sheet in its entirety before beginning the installation.
ALL WARNINGS AND PRECAUTIONS IN THE INSTALLATION AND

FREESTANDING BLOWER SNAP SWITCH RETROFIT KIT
Cat. No. Model Description
H7918
SSK-BLWR-FSB700 Blower Retrofit Kit, FS Woodstoves
The blower must be plugged directly into a properly
grounded three-prong receptacle, 120 VAC, 60 Hz, single
phase. Do not cut or remove the grounding prong from
this plug. Do not route power cord under or in front of
appliance.
Installation must be in accordance with National Electrical Code, ANSI/NFPA 70 - latest edition. In Canada,
the current CSA C22-1 Canadian Electrical Code - latest
edition.
DANGER: Disconnect power before servicing blower.
In the event that you remove the blower for any reason,
make sure a cover plate (available from Lennox Hearth
Products) is installed before using the heater. Excessive
rear wall temperatures will result if the stove is burned
without the cover plate. The cover plate is not necessary
if a blower has never been installed because a knock-out
will be in place to act as the cover.

Leg based units, see instructions on Page 6.
Step 1. From rear of stove, using a 9/16” wrench or socket, loosen both
left and right pedestal mounting bolts but do not fully remove
the bolts from threaded holes as shown in Figure 15.

Step 15.
Wire Ties
Reinstall the blower fan blade.
Reinstall the blower assembly as shown in Figure 2 and the
following instructions; Ensure the wiring harness on the blower
cage is at the bottom right when mounted to the back heat shield
of the stove. Be aware that the blower wiring harness should
be clear of the back of the firebox and blower fan blades. The
blower can now be fastened to the back of the heat shield with
the four screws and washers that were removed earlier in this
step using the 5/32” allen wrench/T-handle. Visually inspect
that the blower is centered in large opening on the back of the
heatshield. If not centered in the opening the fan blades could
make contact with the heatshield making excessive noise. Once
everything is correctly in place you can then tighten down all
four screws. Tighten the screws moderately tight but do not
over tighten as you may strip the holes out.
Figure 15
Step 2. Insert a large flat head screwdriver or pry bar into the small open-
ing between the pedestal mounting flange and the bottom firebox
of the stove. Use the large screwdriver or pry bar to increase
the opening size between the firebox bottom and pedestal. See
Figure 16 - This increased opening between the pedestal and
bottom firebox will be needed to insert the snap switch bracket
mounting tabs.

Step 3. Insert snap switch bracket mounting tabs between the pedestal
and the firebox bottom. See Figure 17.

Step 6. Locate the 3/8” diameter x 1/2” long bolt on the bottom of the
firebox near the draft handle. Using a 9/16” wrench or socket
loosen this bolt but do not remove from threaded hole. See
Figure 20. Note: This bolt was holding the stoves shipping legs
on the stove and should have been reinstalled with the other
three bolts that were holding the shipping legs on the stove per
the pedestal instructions.

Step 4. While holding the snap switch bracket against the pedestal, slide
the bracket towards the rear of the stove until it comes to a stop.
Once the snap switch bracket is in place you can then remove the
flat head screwdriver or pry bar that was used to create the opening
between the firebox bottom and pedestal. See Figure 18.

Step 5. With the snap switch bracket in place, using a 9/16” wrench or
socket wrench you can now tighten down both left and right side
pedestal bolts. See Figure 19.

Step 2. Insert snap switch bracket between the heatshield and the bottom
of firebox making sure entire assembly is on the left side of the
heatshield bolt. Slide back until the notch on the bottom front of
the bracket falls into the lip on the front of the heatshield, and assembly is parallel with side of firebox. See Figures 27 and 28.

Blower Operation
The blower can be operated manually or automatically (blower will
turn on when the stove is hot and turn off when the stove is cool).
The rocker switch on the control panel allows you to select between
manual operation or automatic operation as follows (see Figure 23):
MANUAL OPERATION: Turn rocker switch to the “MANU-
AL” position and adjust rheostat knob to the desired speed. The blower
will have to be manually turned “OFF” by rotating the rheostat knob
counterclockwise until it clicks.
turned on. Likewise, when the stove cools off, the blower is turned off
to prevent circulating cool air. Depending on the size and intensity of the
fire it may be necessary to adjust the fan speed accordingly to ensure uninterrupted fan operation. For example a small fire may require a slower
fan speed to keep the heat output by the fan consistent. If the blower is
operated in manual mode, it may be necessary to adjust the blower speed
as the fire begins to burn down and the stove is no longer hot enough to
effectively heat the air moved by the blower. If the air coming from the
blower feels cool, one should either decrease the blower speed or stoke
the fire to build up more heat.
AUTO OPERATION: Turn rocker switch to the “AUTO” posi-
tion and the rheostat to the ON position (rotate rheostat knob clockwise
until it clicks). When the stove warms up, the blower will automatically
turn on (adjust rheostat knob to the desired speed setting). When the
stove cools down, the blower will automatically turn off.
Rheostat Operation - The highest blower speed is obtained by turning
the rheostat knob clockwise until it clicks “ON”, then rotate towards
“HIGH” to increase blower speed. Rotate the knob clockwise for a
lower speed. To turn off, continue to rotate the knob counterclockwise
until it clicks “OFF.”
Blower Operation Guidelines
While in auto operation mode, the blower will turn off and on based on the
temperature of the stove. Auto operation ensures there is sufficient heat
build-up to warm the air being moved by the blower before the blower is
