CHAPTER 2 - DIRECT VENT INSTALLATION OF VENT/AIR PIPING

2.1.3 Termination Fittings - Through the Roof

1. The vent and combustion air terminations must
include a factory supplied "bird screen" installed as
shown in Fig. 3 and Fig. 4 on page 14
2. The combustion air piping must terminate in an
upside down "U" shape fashion using two 90º
elbows as shown in Fig. 1 on page 12.
3. The vent piping must terminate vertically with a
coupling as shown in Fig. 1 on page 12.
WARNING
Do not extend the vent pipe above the roof
beyond the dimensions shown in Fig. 1 on
page 12. Extended exposure of the vent pipe
could cause condensate to freeze and block the
vent pipe, resulting in substantial property
damage, serious injury, or death.
DO NOT

2.1.4 Direct Vent - Multiple Boiler Installation -
Through the Roof
1. On installations of multiple EXALT boilers, terminate
each vent and combustion air pipe as described in
this manual.
2. The roof penetration of the vent and combustion air
piping must be such that the combustion air inlet
is a minimum 12" [30.5 cm] from the adjacent vent
pipe of the other boiler for installations in the U.S.
as shown in Fig. 5 on page 14. For installations in
Canada, provide clearances as required by CAN/CSA
B149.1.
NOTICE
The combustion air inlet of the EXALT is defined
as being part of a direct vent system. It is not
considered as a forced air intake. The required
clearance of an adjacent boiler vent to a forced
air inlet does not apply in a multiple installation
of EXALT boilers.
