Termination Fittings
1. The vent and combustion air terminations must include
a factory supplied “bird screen” installed as shown in
Fig. 4 page 14 & Fig. 19 page 21.
2. The combustion air piping must terminate through
the sidewall using a 90 º elbow as shown in Figs. 8 or
10 or 13 pages 17 and 18.
3. The vent piping must terminate vertically through the
roof with a coupling to accept the bird screen and
must be located 12” [30.5 cm] (18” [45.7 cm]
Canada) above the highest anticipated snow level.
Do not extend the vent pipe above the roof beyond
the dimension shown in Fig. 21 on page 23.
Extended exposure of the vent pipe could cause
condensate to freeze and block the vent pipe.
WARNING
Direct Vent - Multiple Boiler Installation - Vertical
Vent and Sidewall Combustion Air
1. On installations of multiple PRESTIGE boilers, ter-
minate each vent and combustion air piping as
described in this manual.
2. Each vent and combustion air termination must be a
minimum 12” [30.5 cm] from the adjacent termina-
tion for installations in the U.S. as shown in Fig. 22.
For installations in Canada, provide clearances as
required by CAN/CSA B149.1.
The combustion air inlet of the PRESTIGE is defined
as being part of a direct vent system. It is not con-
sidered as a forced air intake. The required clear-
ance of an adjacent boiler vent to a forced air inlet
does not apply in a multiple installation of PRES-
TIGE boilers.
