Installation
NOTe: Cold return water temperature (Sustained temperatures below 140 degrees Fahrenheit) will lead to condensation in the firebox.
This moisture can lead to creosote formation. To help minimize moisture and creosote, it is strongly recommended that some form of
temperature balance is incorporated into the return water system.
NOTICe: When installing with the atmospheric conversion: All of the pressurized system components shown are not necessary. Air
vents or bleeders will need to be removed from the plumbing system to prevent air from entering the lines. Control Dipswitch #6 will need
to be turned “ON”.
