PARLOUR PELLET 3000 PELLET HEATER

APPENDIX C – FINE TUNING
Because of the variability of pellets (i.e., length
thickness, density, quality of sawdust), you
might have to—from time to time—fine tune
your heater to compensate for pellet quality.
Following are some suggestions for fine tuning.
There are three (3) fine-tuning adjustment
components:
1. The Trim Button located on the control plate
(see Figure 13) will allow you to change the
feed rate on each setting (i.e., Hi, Med,
Low). By turning the trim button clockwise
you can increase the feed rate, and by
turning the trim counterclockwise you can
decrease the feed rate. For example, if the
pellet you are using is a hardwood pellet and
longer than 1”, then the stove could go out
on the low setting for lack of fuel. Turn the
trim clockwise to increase fuel and thus
sustain the fire.
2. The Fan Trim Pot Adjustment is located on
the circuit board (see Figure 17). Please note
the two fan trim pots marked on the drawing
(lower left hand corner). By using a small
slot screwdriver you can adjust fan speeds to
compensate for poor pellets or airflow. By
turning the trim pots clockwise you can
speed up the fan speed on both Hi and Low
settings. You will have to experiment with
the setting to determine the proper burn. A
good, brisk flame that is yellow, not orange,
is what indicates a good burn.
3. Outside air hook-up can create combustion
problems if the outside air flex tube is longer
than 3’ (three feet). Increase size of flex tube
on runs over 3’. Use 4” flex if you are going
up into an existing chimney.
