1.To open/remove Burner Swing Door (mounted on Cast Iron Section/Burner Swing Door/Smoke Box

Assembly) and door mounting bracket for front jacket panel installation:

a.Loosen but not remove door left side latching hardware (3/8”-16 x 1-3/4” tap bolt).

b.Loosen and remove door right side latching hardware (3/8”-16 x 1-3/4” tap bolt and 5/16” washer) and set aside.

c.Remove door left side latching hardware (3/8”-

16 x 1-3/4” tap bolt and 5/16” washer) and set aside.

d.Lift the door off mounting bracket and set aside.

e.Remove two 5/16”-18 – ¾” hex head cap screws securing door mounting bracket to front section and set aside.

f.Remove door mounting bracket and set aside.

g.Note/mark cap screw bosses on front section left side; locate/mark similar two bosses directly opposite on front section right side. These four front section bosses are front jacket panel and door mounting bracket attachment points.

See also Figure 7 “Purpose of Tappings & Bosses”.

2.Open Jacket Carton and locate jacket front panel

(has factory attached 1” fiberglass insulation). See also “Repair Parts” Section, “Jacket Assembly” illustration for part identification.

3.Open Part Carton, locate Hardware Bag, remove two 5/16”-18 x ½” Phillips pan head machine screws.

4.Place front jacket panel over front section attachment bosses and align jacket holes with front 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.

7.Thirdly, insert 5/16”-18 – ¾” hex head cap screw thru door mounting bracket lower hole and lower hole on left side of front jacket panel simultaneously, and, fasten the bracket and panel to casting hand tight.

8.Finally, tighten both sets of hardware to secure the bracket and front jacket panel.

9.Inspect fiberglass rope located on the swing door. The rope must be evenly distributed around the perimeter of the door groove and cannot bunch or overhang. Repair or replace, if the rope is damaged, or, there is a gap between the rope ends.

10.Inspect burner swing door insulation for damage and proper type.

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.
