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.
