NOTICE: When installing with the Atmospheric Conversion, all
of the pressurized system components shown are not
necessary. Air vents or bleeders should be removed from the
plumbing system to prevent air from entering the lines. Control
dipswitch #6 must be “ON”.
NOTE: Cold return water temperature (Sustained temperatures below
140 degrees Fahrenheit) will lead to condensation or moisture in the
firebox. This moisture can lead to creosote formation. To help minimize
moisture and creosote, it is strongly recommended that some method
of temperature balance is incorporated into the return system.
