• To adjust the low burn rate, slide the heat selector switch to the “1” or low setting and observe the
auger light. This will indicate when the auger is running.
• Turn the adjustable resister “L” clockwise to increase the burn rate, and counter-clockwise to
decrease the burn rate.
• To adjust the high burn rate, slide the heat selector switch to the “3” or high setting and turn the
adjustable resistor “H” clockwise to increase the burn rate, and counter-clockwise to decrease the
burn rate.
Note: Fan voltages are fixed and ay not be adjusted. The Medium fuel feed rate is fixed.
Recommended timings:
Low – 2.0 seconds on approximately
8.0 seconds off approximately
High- 2.0 seconds on approximately
3.0 seconds off approximately
Adjusting the feed rate is done by changing the off time between cycles
