section boss holes.
5. Firstly, install two 5/16”-18 x ½” Phillips pan head
machine screws hand tight to secure front jacket
panel right side to casting
6. Secondly, insert 5/16”-18 – ¾” hex head cap
screw thru door mounting bracket upper hole
and upper hole on left side of front jacket panel
simultaneously, and, fasten the bracket and panel to
casting hand tight.

By design, for all models, cast bars on front section
between the combustion chamber, and, between the
left and right side 2nd and 3rd pass flueways should
make an impression in door insulation to seal the
chambers.
