Install vent system in accordance with these
instructions and with Part 7, V_'nting of Equipment,
National Fuel Gas Code, ANSI Z223.1/NFPA 54,
CAN/CGA B149, or applicable provisions of the local
building codes•
2. Boiler is a direct vent appliance. The boiler vent is
listed as Category IV.
rA |vivhl ;t ii ,,
This vent system will operate with a positive
pressure in the vent pipe, Do not connect vent
connectors serving appliances vented by natural
draft into any portion of mechanical draft systems
operating under positive pressure.
2 Determine air inlet vent location
a Provide I foot clearance between bottom of vent
and ground level and normal snow lines.
3 Refer to venting diagrams (Figures 7 through 12) for
typical sidewall and vertical vent/air inlet piping.
a. Maintain distances between air inlet, vent. and
exhaust vent as indicated in Figures 7, 8, and 11.
Do not space the air inlet vent and exhaust vent
greater than 6 feet apart•
b.
When sidewall venting multiple 3" concentric vent
kits, the vent kits must remain in a horizontal
plane and placed no closer than 8" center to
center• Also refer to instructions provided with
vent kit.
c. When sidewall venting multiple VI000 vent kits
refer to instructions provided with vent kit.
Flue gases will condense as they exit the vent
termination. This condensate can freeze on exterior
building surfaces which may cause discoloration of
these surfaces.
i. Determine exhaust vent location,
a. Vent is approved for 0" clearance to combustible
constr_ction.
b. Provide 3 feet clearance above any forced air
inlet within 10 feet.
C.
d,
e.
Provide 1 foot clearance below, I foot beside, or
1 foot above any door, window, or gravity air
inlet into any building•
Provide I foot clearance between bottom of vent
terminal and ground level and normal snow lines•
Provide 4 feet horizontal clearance from, and in
no case above or below, unless a 4 foot
horizontal distance is maintained, from electric
meters, gas meters, regulators and relief
equipment.
Do not locate vent terminal over public walkways
where condensate could create a nuisance or
hazard.
g.
h.
i.
When adjacent to a public walkway, locate vent
terminal at least 7 feet above grade.
Do not locate directly under roof overhangs to
prevent icicles from forming.
Provide 3 foot clearance from inside corner of
adjacent walls•

For minimum and maximum vent pipe lengths refer
to Table 4,
Use only 3" PVC, CPVC, or ABS solid schedule 40
or 80 material for exhaust vent, 4" PVC, CPVC, or
ABS solid schedule 40 or 80 pipe is also approved
under special conditions; see Section E, Extended
Vent Lengths with 4" Pipe, in this section for details,
FOAM CORE PIPING IS NOT APPROVED•
Vent connection is located on rear of boiler and is
marked "exhaust outlet".
Alljoints must be properly cleaned, primed, and
cemented, Use only approved cement and primer for
PVC, CPVC and ABS materials. Cement must
conform to ASTM D-2564 (PVC) or D2235 (ABS).
Remove all burrs and debris from joints and fittings.
Horizontal lengths must slope back to boiler
connection not less than 1/4" per foot to allow
codensate to flow back to boiler•
A screened 3" straight coupling is provided with
boiler for use as a vent termination• Optional vent
terminations approved for use with the Pinnacle
boiler are 3" concentric KGAVT0601CVT Vent Kit
and V1000 Vent Kit. Both are available from a
Peerless Distributor.
Vent piping must be supported at 4 ft. intervals to
prevent sagging. The boiler is not intended as a
support means for vent.
