The following section is provided as a guide
to a standard B-type vent installation.
Standing codes requirements concerning B-
type vent installations may vary within your
state, province or local codes jurisdiction.
Therefore, it is recommended that you check
with your local building codes for specific
requirements or in absence of local codes,
follow Section 7.0 of the current
National Fuel
Gas Code NFPA No. 54/ANSI Z223.1
and in
Canada with
CAN/CSA B149 for Category I

.
This gas appliance must be vented to the
outdoors only and may not be terminated into
an attic space or into a chimney flue servicing
a solid fuel burning appliance.
This appliance may be vented through a
manufactured chimney system or a masonry
chimney using a B-vent adapter or a chim-
ney liner system if all are listed, inspected
and approved by local codes and/or building
authorities.
The examples shown in Figure 9, page 10
are typical of most B-vent installations and
code practices.
