To perform adjustments, follow the outline below:
Procedure for adjusting feeding time:
Enter service menu by pressing "+" and "-" buttons at the same time. Enter service level. Scroll through service
level by pressing "+" (up) or "-" (down) button.
Adjust the basic feeding time: "Menu #23 value" (normally .8 sec. adjustable from 0.5 to 1.5 sec.).
If CO2 level is too high: reduce the feeding time (example: 0.75 sec.); if CO2 level is too low: increase the
feeding time (example: .90 sec.). Experiment until you find the correct CO2 and CO levels.
The pellet fuel delivery is adjusted proportionately for all output levels as the fan speed is fine tuned
automatically with each output level.
