WARNINGS
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 Elec-
trical 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.

Blower Operation Guidelines
While in auto operation mode, the blower will turn off and on based on
The temperature of the stove or fireplace insert. Auto operation ensures
there is sufficient heat build-up to warm the air being moved by the blow-
er before the blower is 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 ac-
cordingly to ensure uninterrupted fan operation. For example a small fire
may require a slower fan speed to keep the heat output by the fan con-
sistent. 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.
NOTE: Turn blower off before opening the door to load the fuel.
BLOWER OPERATION (OPTIONAL KIT)
Figure 29 - Blower Controls
Blower Operation
The blower can be operated in either manual or automatic mode. When
operated automatically, the blower will turn on when the stove is hot,
and turn off when the stove is cool.
MANUAL OPERATION: Flip blower mode switch to the
manual position (up) and adjust blower speed dial to desired setting.
To turn blower off, rotate blower speed dial counter clockwise until it
clicks “off.”
AUTO OPERATION: Flip blower mode switch to auto posi-
tion and turn blower speed dial clockwise until it clicks out of the “off”
position. When the stove warms up (approx. 15-20 Mins), the blower
will automatically turn on (adjust blower speed dial to desired speed
setting). When the stove or insert cools down, the blower will auto-
matically turn off.
