10. For air intake, assemble copper tubing
parts (see Figure 9) provided with boiler
and install the assembly on boiler air
intake inlet, pointing toward outside wall
opening.
11. Complete both tubing runs through out-
side side wall opening. Avoid routing tub-
ing internal to walls or ceilings; always
allow sufficient access to tubing for
annual inspection.
12. Both tubing runs must terminate exactly
1-3/4" beyond the surface of the outside
wall for proper insertion into vent termi-
nal. If necessary, cut the tubing to proper
length and remove all burrs.
13. Seal all tubing run joints and boiler con-
nections with a high-temperature RTV
sealant (provided). APPLY SEALANT TO
OUTSIDE OF MALE TUBE ENDS ONLY,
1/4 inch from the tube end, not inside of
the tubes or fittings.
14. If vent length exceeds 5 feet, install one
vibration isolating-type hanger on each
tubing run (to prevent sagging).
15. Install the insulation (provided) around
stainless steel vent pipe and secure.
Insulation must cover the vent pipe pass-
ing through the wall and terminate at
outside wall surface.
