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 un-  
interrupted 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.  
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.  
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.”

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  
turned on. Likewise, when the stove cools off, the blower is turned off
