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 specic
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

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
