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 betweenSMITTY wrote:Minus? On my setup that indicates NO draft ... actually a backflow at that stage .... hence the red because that's not good ....
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).
