Remove and clean flue pipe.
Check chimney and clean if necessary.
Remove hopper and check for rust at bottom edges. If rust is
found, remove it with a file or sandpaper and paint the area with spray

removed and cleaned. Also remove any rust or corrosion from the area
where the pusher block slides and spray with WD-40 or other rust

procedure. If the pusher block cannot be moved, call your
dealer.

feed motor will result. This will be considered neglect and will
