25. Install the new Condensate Evaporator on top of the
insulation.
26. Clean the tubesheet and O-Ring sealing surfaces (see
Figure 4).
27. Reinstall the Heat Exchanger Coil on the Insulation.
Pull the Heat Exchanger Coil and the Bottom Insulation
forward together to align with the mounting plate (see
Figure 5).
28. Install the manifold and manifold bolts. See Figure 6
for long and short bolt positions.

NOTE:
When cleaning, be careful
not to push the tube sheet into the
combustion chamber. If you do,
thread a couple of bolts into it
and pull it back in place.
Brush off all dust and debris
with a brush and wipe it down
with a cloth.
Apply silicone grease (supplied)
to O-Rings.
Clean the tube sheet and O-ring
sealing surface with a nylon brush,
then brighten the tube sheet
surface with 320 grit emery cloth.

and
SR/SRC400
: Tighten all long bolts
HAND TIGHT; then tighten the bolts next to the short
bolts a little more with a wrench.
• Insert and start the two short bolts until they engage
three or four threads, then tighten all bolts according to
the normal torque pattern shown on Page 5.
•
SR/SRC333
: These models use long bolts only. Tighten
all bolts HAND TIGHT; then tighten according to the
normal torque pattern shown on Page 5.
*Hand-tighten all long bolts; then tighten indicated bolts enough to
allow short bolts to engage.
