E. EXHAUST VENT/AIR INTAKE
INSTALLATION
1. Figure 12.1 shows the exhaust connection on top of
the boiler, near the rear in the center.
a. The exhaust connections for the IEW-199 (3") and
IEW-399 (4") are male CPVC pipe.
b. These connections are to be joined with suitable
PVC/CPVC adhesives in accordance with
manufacturers’ instructions.
2. The Air Intake connection is to the right of the exhaust.
3. Both connections are clearly marked.
4. Remove all burrs and debris from the joints and fittings.
5. Horizontal lengths of exhaust vent must be installed with
a slope of not less than 1/4" per foot (21 mm per meter)
toward the boiler to allow condensate to drain from the
vent pipe. If the vent pipe must be piped around an
obstacle that causes a low point in the piping, a drain
with an appropriate trap must be installed.
6. All piping must be fully supported. Use pipe hangers
at a minimum of 4 foot (1.22 meter) intervals to
prevent sagging of the pipe.
7. Exhaust and air inlet piping is to be supported
separately and should not apply force to the boiler.
8. Penetration openings around the vent pipe and air
intake piping are to be fully sealed to prevent exhaust
gases from entering building structures.
9. PVC & CPVC Piping:
a. Use only solid PVC or CPVC Schedule 40 or 80
pipe for exhaust venting. Cellular core PVC or
CPVC is not approved for exhaust vent.
b. All joints in vent pipe, fittings, attachment to the
boiler stub, and all vent termination joints must be
properly cleaned, primed and cemented. Use only
cement and primer approved for use with PVC or
CPVC pipe that conforms to ANSI/ASTM D2564.

This appliance uses a positive pressure venting
system. All joints must be sealed completely to
prevent leakage of flue products into living spaces.
Failure to do this may result in severe personal injury,
death or major property damage.
