Atmospheric Conversion: Item # 1-00-232200, provides automatic ll, and converts the heating

system plumbing from pressurized to a zero pressure system. Allows for installation into more

places where codes and standards restrict pressurized systems. Note that when using the atmo-

spheric conversion, air bleeders and check valves may actually allow air into the lines. Another

reason it is important to have a licensed Plumber involved in each phase of your installation.

When using the atmospheric conversion, the circuit board dipswitch #6 must

be in the “ON” position. This will lower the overheat temperature parameters

to prevent boiling of the water. Since altitude affects the boiling point, it is also

recommended to set #6 to “ON” at elevations above 3000 ft.
