NOTICE

When securing burner swing door make sure door is drawn-in equally on both sides.

d.Use a hand or socket wrench to tighten door hardware. ALWAYS START WITH RIGHT SIDE TAP BOLT FIRST. Use an alternating tightening method from right side tap bolt to left side tap bolt to tighten door equally, until sealed, without applying excessive torque.

NEVER TIGHTEN LEFT SIDE TAP BOLT FIRST, OR, EITHER PIECE OF HARDWARE 100% WITHOUT USING THE ALTERNATING METHOD DESCRIBED ABOVE. See Figure 5B.

e.Failure to follow the prescribed procedure could cause thread damage to casting and /or leak at the door seal. IF LEFT SIDE TAP BOLT IS TIGHTENED BEFORE RIGHT SIDE TAP BOLT, RIGHT SIDE OF THE DOOR CAN NOT BE DRAWN-IN TO PROVIDE AN AIR- TIGHT SEAL, as shown in Figure 5C. Applying excessive torque will only cause thread damage.

G.Jacket Rear Panel Installation.

1.Locate jacket rear panel (has factory attached 3” fiberglass insulation) inside Jacket Carton. See also “Repair Parts” Section, “Jacket Assembly” illustration for part identification.

2.Locate and remove from Hardware Bag rear panel mounting hardware – (2 pcs) 5/16”-18 x 3” lg. tap studs, (2 pcs) 5/16”-18 plated acorn nuts, (2 pcs)

5/8” x 2-9/32” round spacers and (2 pcs) 5/16”-18 x ½” Phillips pan head machine screws.

3.Locate rear panel two lower attachment bosses on rear section. See Figure 7 “Purpose of Tappings &

Bosses”.

4.Thread both 5/16”-18 x 3” lg. tap studs, with short threaded end, into lower attachment bosses on rear section.

5.Install both 5/8” x 2-9/32” round spacers over tap studs.

6.Place rear jacket panel over rear section, so both tap studs clear thru lower panel holes, rear section cleanout openings clear thru matching panel cutouts and brass sample port plug clears panel matching hole.

7.Secure panel bottom to studs with acorn nuts hand tight.

8.Align upper panel attachment holes with smokebox upper attachment bosses and install 5/16”-18 x ½”

Phillips pan head machine screws hand tight.

9.Securely tighten rear jacket panel mounting hardware.

10.Locate/remove four #8 x ½” shoulder sheet metal screws from Hardware Bag, then, install them into rear panel flange holes.

H.Flue Cleanout Covers and Smokebox Collar Installation.

1.Remove two cast iron Cleanout Covers, cast iron

Smokebox Collar and the tube of hi-temperature silicon adhesive sealant from Part Carton. See also

“Repair Parts” Section, “Bare Boiler Assembly” illustration for part identification.

2.Check the rope gasket factory attached to the covers. Repair or replace, if the rope is damaged, or, there is a gap between the rope ends.

3.Locate/remove four 5/16”-18 – 7/8” hex head cap screws from Hardware Bag.

4.Apply a drop of supplied Anti-seize (pouch provided in Part Carton) to each of four (4) 5/16”-18 x 7/8” hex head cap screws for rust protection and to facilitate easy removal for future service.

5.Position left Cleanout Cover over rear section cleanout opening, align section boss holes with Cleanout Cover holes, install both 5/16”-18 – 7/8” hex head cap screws hand tight, then, alternately tighten them with open end or socket wrench.
