Venting/Air Intake Piping - Burnham MINUTEMAN II Installation, Operating And Service Instructions

VI. Venting / Air Intake Piping
The gasketed vent system components pictured below in Figure A are being phased in and each vent
component is interchangeable with the previously supplied gasket-less venting components. The newer
vent components are generally quicker and easier to join, as they do not require the sealant application and
their clamp bands are attached.
In the event a gasketed vent component and a
gasket-less vent component must be intercon-
nected, follow the instructions associated with
Figure 10B or 10C. The two guiding principles of
these instructions are as follows:
1) Any joining of vent components
that involves at least one
gasket-less vent component
always requires the sealant
application.
2) The female end of a gasket-less
vent component always requires
a clamp band, regardless of the
design of the mating male vent
component.
Each gasket-less vent component is supplied with a clamp band and sealant.
A Vent Transition Kit, part number 11302, is available that contains one clamp band and one 3 ounce tube
of sealant.

General Guidelines.
1. Vent system installation must be in accordance with
National Fuel Gas Code, ANSI Z223.1, Venting of
Equipment, or applicable provisions of local
building codes. Contact local building or fire
officials about restrictions and installation inspection
in your area.
2. This appliance requires a Special Gas Vent. The
product is designed to use supplied AL 29-4C
Stainless Steel vent system components. The
following manufacturer's offer similar AL 29-4C
components and are approved for use with this
product:
Heat-Fab Inc. - Saf-T-Vent (800-772-0739),
Flex-L International Inc. - Star-34 (800-561-1980),
Protech Systems, Inc. - FasNSeal™ (800-766-3473),
and Z-Flex U. S., Inc. - Z-Vent (800-654-5600).
The use of these alternate manufacturer's venting
systems will require adapters to connect to the
supplied vent connector and vent terminal. These
adapters are not supplied with this unit and should
be obtained from the supplier of the alternate
manufacturer's venting system. See Table 7 for
complete parts list.

NOTICE
Do not use this boiler with galvanized, 304 or 31
stainless steel or any other non AL2-4C
vent systems.
3. Vent length restrictions are based on equivalent
length of vent pipe (total length of straight pipe plus
equivalent length of fittings). Maximum vent length
®
is listed in Table 6. Do not exceed maximum vent/
air intake lengths. Table 7 lists equivalent length for
®
fittings. Do not include Vent Terminal or Vent
Connector in equivalent feet calculation.
