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.
BLOWER OPERATION

Figure 11 - Blower Controls
Blower Operation
The blower can be operated manually or automatically (blower will
turn on when the insert is hot and turn off when the insert is cool).
The rocker switch on the control panel allows you to select between
manual operation or automatic operation as follows (see Figure 10):
MANUAL OPERATION: Turn rocker switch to the manual position (up)
and adjust rheostat knob to the desired speed. The blower will have to
be manually turned “OFF” by rotating the rheostat knob counterclock-
wise until it clicks.
AUTO OPERATION: Turn rocker switch to the “AUTO” position and
the rheostat to the ON position (rotate rheostat knob clockwise until it
clicks). When the insert warms up, the blower will automatically turn
on (adjust rheostat knob to the desired speed setting). When the insert
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 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.
