NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

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 appliance. Auto operation ensures there is suffi-

cient heat build-up to warm the air being moved by the blower before the

blower is turned on. Likewise, when the appliance 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 blower speed ac-

cordingly to ensure un-interrupted blower operation. For example a small

fire may require a slower blower speed to keep the heat output by the

blower 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 appliance 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

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 19):

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

clockwise until it clicks.

AUTO OPERATION: Turn rocker switch to the “AUTO” posi-

tion and the rheostat to the ON position (rotate rheostat knob coun-

terclockwise until it clicks). When the stove warms up, the blower will

automatically turn on (adjust rheostat knob to the desired speed set-

ting). When the stove cools down, the blower will automatically turn

off.
Rheostat Operation - The highest blower speed is obtained by turn-

ing the rheostat knob counterclockwise 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 clockwise

until it clicks “OFF.”
