Minimum size of chimney

The minimum recommended chimney size is 8" x 8"

(6 3/4" x 6 3/4" inside liner) or 6" diameter with a

minimum height of 20 feet. Use a 6" flue pipe for

connection to an existing chimney.

Installing the flue pipe

z Slide 6" Insert flue pipe onto the flue outlet and

secure with 2 screws.

z Install flue connections between boiler and chimney

to slope up at least 1/4" per foot to the chimney.

z Connect the flue pipe to the chimney above the

bottom of the chimney to prevent blockages.

z Install cleaning and service hatches for cleaning the

flue system.

After starting the burner, set breeching draft

to -.01 to -02 inches WC with a draft gauge. (The

overfire pressure can be positive). If necessary, install

draft controllers in the flue system to maintain the

negative pressure in the system or to meet code

requirements. Always install the draft controller in

vertical position. Use a draft gauge when making

adjustments.
