List the Properties of a Good and Poor Flame
Before we start adjusting the stove, it is important to know what a good flame is and what a poor
flame is. In this portion of the lesson a picture followed by a description of each flame is given.
(Figures 23 through 28). The three settings we can change that effect the flame are; pellet feed
rate, agitator speed, draft fan, and damper. Each adjustment will be discussed separately.

Refer to table 4 for the proper button to select the desired feed rate. You have a choice of feed
rates between 1 through 10. The higher the feed rate the more pellets will be fed into the ash
pan, this will in turn provide more pellets to burn creating a higher heat output.
To make fine adjustments on pellet feed rate, observe the rate of burn in the ash pan. If the
pellets are building up faster than they burn, and assuming you're not adjusting your draft fan,
you would need to decrease the pellet feed rate. Conversely, if the pellets are burning out
quicker and you choose not to alter the draft fan, a higher pellet feed rate needs to be selected.
