NOTICE
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 4C or 4D. 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 6116302, is available that contains one clamp band and one 3 ounce tube
of sealant.

based vent systems.
Do not use a barometric damper or drafthood with this boiler.
Do not use vent dampers with this boiler.
Moisture and ice may form on surfaces around termination. To prevent deterioration, surfaces should
be in good repair (sealed, painted, etc.).
This boiler needs fresh air for safe operation and must be installed so there are provisions for
adequate combustion and ventilation air.
Do not operate boiler where gasoline or other ammable vapors or liquids, or sources of hydrocarbons
(i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) are used, stored and/
or present in the air.
Do not exceed maximum vent length of 25 equivalent feet.
