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.
