1. Locate the flue baffle carton. Each flue opening
will get two (2) short baffles and three (3) long flue
baffles.
2. Insert the first short flue baffle, wide end first,
directly above the upper 'J' bolt attachment lug, so
that the baffle rests on the pin row directly behind
the lug.
3. Insert the second short flue baffle, narrow end first,
two (2) pin rows down from the first short baffle.
4. Insert the three (3) long flue baffles, continuing
down on every second pin row and alternating
wide and short ends, so that the end result matches
Figure 18.

5. Locate the cover plates, carriage bolts, nuts and
washers in the boiler assembly carton(s).
6. Remove insulation from two 3/8" diameter holes in
flue cover plates using a 3/8" drill bit which can be
rotated through insulation by hand.
7. Hook flue cover 'J' bolts over attachment lugs.
8. With one hand, hold top 'J' bolt between your index
and middle fingers. With the other hand, hold flue
plate on a slight inward angle, align top hole with
end of 'J' bolt and force it through as far as possible.
Repeat similar process for bottom 'J' bolt.
9. Holding threaded end of top 'J' bolt, pull outward
and at the same time push flue cover plate against
castings. Place one finger across 'J' bolt at base of
flue cover plate hole. Place 5/16" washer, split lock
washer and brass nut on end of 'J' bolt. Hand tighten
only. Repeat similar process for bottom 'J' bolt.
10. Push upward on bottom edge of flue cover plate to
eliminate sag in hardware. Tighten brass nuts with
a deep socket or wrench until insulation on cover
plate provides an adequate seal to casting. If after
tightening, a gap is still evident where the sections
join, apply silastic along top and bottom edge of
insulation board.
11. Repeat steps 2 through 10 for mounting remaining

flue cover plates.

C.
MOUNT REAR OBSERVATION PORT
COVER, Refer to Figure 15.
1. Apply a ¼" bead of Silastic sealant along the groove
on the inside face of the rear observation port cover.
2. Mount the rear observation port cover onto the rear
section (with the word "Top" in the upright position)
using the (4) 5/16"-18 X 1" cap screws and washers
provided.
D.
INSPECT SEALS
1. A visual inspection should be made of all sealed
joints and repairs made if necessary. A darkened
boiler room with a light source in the combustion
space and canopy will aid this inspection.
E.
