21.Control circuit transformer.

22.24 volt ac transformer.

23.12 volt dc power supply.

24.SOLA hydronic and flame supervision control.

25.Repeat cycle timer. This timer will ensure that a forced shut down and pre-start safety check is performed at least once in a 24

hour period. This timer has been incorporated into the SOLA control for newer boilers.

26.Gas limiting orifice valve. This valve is used to increase or decrease the gas / air ratio for combustion. Adjustments are made by removing the cap and using a flathead screwdriver. Clockwise rotation will increase the flue outlet % O2 levels and counter- clockwise will decrease the flue outlet % O2 level. Starting point adjustments are listed in the table. This vale is factory set and the number of turns out is written in black adjacent to the adjustment cap.
