Allow stove and chimney to warm up. Insert draft gauge through predrilled hole in upper portion of fire door. Open air shutter (located on bottom of scroll between
stoker motor and gear box about ½”). Then with stoker motor running and feeding coal adjust the
barometric damper until draft gauge reads (-.02). If draft is less than a (-.02) draft with the
barometric damper closed you must close the air shutter (between gear box & stoker motor) a
little and recheck. Repeat until you obtain a (-.02) draft. If the draft is higher than (-.02)
you must adjust the barometric draft regulator. Move the weight on barometric regulator left or
right to obtain the (-.02) Recheck the draft until you obtain a (-.02).
