IT IS CRITICAL FOR THE CORRECT OPERATION OF YOUR STOVE THAT THE DAMPER, COMBUSTION FAN SPEED AND HI-LO FUEL FEED BE SET CORRECTLY!

AIR INLET DAMPER:

The damper is a plate that helps control the amount of airflow supplied for combustion. With the damper pushed all the way in the airflow is at its minimum. As the damper is pulled out, more air is allowed to flow through the combustion area.

It will be necessary to monitor the appearance of the flame. Start by running your heater on HIGH (#4) setting for approximately 10 minutes, then push the damper all the way in and evaluate the appearance of the flame. If your flame is smoky red / orange with evidence of soot at the top of the flame, you need more combustion air. Continue to pull out the damper about a ¼” at a time, opening the damper as needed to obtain a flame that is yellow and a fire that is brisk enough to carry ash out of the grate, but not so brisk that it carries pellets out as well (known as “Pop corning”). Normally you should find that the damper will need to be closed two-thirds to three quarters, but will vary with length of vent run, pellet quality and elevation.

Follow the same procedure but at LOW (#1) setting as well. This will now give you your approximate damper settings needed to run your heater efficiently.

Symptoms of excessive combustion air include: fuel burns to quickly resulting in smoking or smoldering pellets, white to yellow flame, and the burning pellets will lift off the grate and fly up into the air (popcorning) Contributing factors: venting system providing excessive draft.

COMBUSTION FAN SPEED (Draft): In a few instances because of prevailing conditions pertinent to your specific installation, or even different batches of pellet fuel, the COMBUSTION FAN SPEED may be adjusted to raise or lower the amount of air moving through the grate for the cleanest burn. Fan speed can be adjusted by adjusting the FAN POD. COUNTER CLOCKWISE to INCREASE the speed and CLOCKWISE to DECREASE the speed of the combustion fan.

You may wish to use a qualified technician if you are not comfortable changing these settings. There may be a charge for this setting. Check with your Cheap Charlie Dealer for details.
