Don't forget to retighten the
bolt after removing the
plate.
Important
Your stoker has a built-in feature that lets you take the air that normally blows out from the front and
puts it out the top into a 6" duct.
To do this, remove the 6" round plate from the top of the unit by removing the bolt located in the top of
the firebox. A 3/4" wrench will fit the bolt. Remove the plate from the front by using the small handle on the
plate. Turn bolt all the way in and tighten.
Next, block off the front blower opening with a piece of heavy fiberglass rope. Insert rope through the
6" duct opening and push front to block off the front air passage.
Now, install a 6" starting collar in the 6" hole and run duct to desired room.
NOTE: THIS DUCT OPTION IS INTENDED TO SUPPLY ONE REGISTER ONLY,
WITH A MAXIMUM DISTANCE OF 20 FEET FROM UNIT.
