EXHAUST/AIR INTAKE TUBING
Vent installations shall be in accordance with Part 7,
Venting of Equipment, of the National Fuel Gas Code,
ANSI Z223.1, or applicable provisions of local building
codes.
Only 2" stainless steel tubing provided by Slant/Fin
Corp. can be used for exhaust venting. 2" copper DWV
tubing for air intake can be provided from Slant/Fin or
local supplier. See Figure 3.
7.
For exhaust, install the stainless steel elbowed
tubing length (provided) on the boiler exhaust out-
let, pointing toward the outside wall opening.
8.
For air intake, assemble copper tubing parts (see
Figure 4) provided with boiler and install assembly
on boiler air intake inlet, pointing toward outside
wall opening.
9.
For extended rear-wall venting only, complete both
of the tubing runs through outside rear wall open-
ing. Avoid routing tubing internal to walls or ceil-
ings; always allow sufficient access to tubing for
annual inspection.
10. Both tubing runs must terminate exactly 1-3/4"
beyond outside wall surface for proper insertion
into vent terminal. If necessary, cut tubing to prop-
er length and remove all burrs.
11. Seal all tubing run joints and boiler connections
with high-temperature RTV sealant (provided).
APPLY SEALANT TO OUTSIDE OF MALE TUBE
ENDS ONLY, 1/4 inch from the tube end, not
inside of tubes or fittings.
12. If vent length exceeds 5 feet, install one vibration
isolating-type hanger on each tubing run (to pre-
vent sagging).
13. Install the insulation (provided) around stainless
steel vent pipe and secure. Insulation must cover
the vent pipe passing through the wall and termi-
nate at outside wall surface.
14. Proceed to Step 2 on Page 8.
