VERTICAL VENT PIPE INSTALLATION INSTRUCTIONS
H. INSTALLATION
• Vent Adaptor.
A. Attach vent adaptor at draft inducer collar. See
figure 24 on page 27. Use Kit # 56111101 for DV
50-125 and Kit # 56111102 for DV 150-200, or
equivalent.
!
WARNING
Make sure that all vent pipe and connectors
are secured because unsecured vent pipe
connections may loosen. This can allow
combustion products to collect in the
structure, resulting in injury or death.
• Vent Connector.
A. Install vent connectors without any dips or sags.
Slope them upward from boiler at least 1/4" per
foot. To prevent sagging, at each joint support vent
connectors and horizontal portions using hangers,
straps or equivalent. Seal all connections where
vent connectors enter chimney. See figure 17 on
page 24.
• Vertical Vent.
A. Install vent materials following their listing terms,
manufacturer’s instructions, these instructions
and local codes. A gas vent passing through a roof
must extend through roof flashing, jack or thimble.
It must terminate above the roof surface. See
figures 20 & 21 .
I. EXISTING VENT CONSIDERATIONS
Masonry chimneys previously used for venting equipment
should be suitably per NFGC standard. Also provide an
accessible clean out per the latest revision of the NFGC,
ANSI Z2231, AND NFPA 54.1
1.
Vent Inspection
A. Make sure existing vent or chimney is the proper
size and construction for appliances that will use
it. The best way to do this is to size as if it were a
new installation. Compare the existing vent to your
calculations and make necessary corrections.
B. Examine vent or chimney cleanouts to make sure
they remain tightly closed when not in use. Make
sure vent or chimney passageway is clear and free
of obstructions. Look for evidence of condensate
or deterioration in vent or chimney. Either of these
means an inadequate vent.
C. If you find an inadequate vent or chimney, do not
leave it as is. Repair or replace it. A new vent must
meet these instructions and the latest revision of
the National Fuel Gas Code ANSI Z223.1/NFPA 54.
