Category IV Installation of Vent/Air Piping
Category IV - Multiple Boiler Installation - Sidewall
1. On installations of multiple PRESTIGE boilers, ter-
minate each vent pipe as described in this manual.
2. The wall penetration of the vent should be a mini-
mum 12” [30.5 cm] from the adjacent vent pipe of
another boiler for installations in the U.S as shown
Fig. 32. For installations in Canada, provide clear-
ances as required by CAN/CSA B149.1.
Fig. 32 shows one option for vent terminations of
multiple PRESTIGE boilers. Any vent termination
option shown in Figs. 26 through 31 pages 30 and 31
can be used for multiple PRESTIGE boilers. The 12”
[30.5 cm] minimum distance between centerlines of
the vent piping must be maintained for any chosen
option.
Reference Figs. 26 through 31 pages 30 and 31 for
the configuration dimensions of the vent for each
unit installed in a multiple installation.
