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.
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.
