Sidewall Vent Termination - IBC EX Series Installation & Operating Manual

For roof top venting of multiple boiler sets, group all intake terminals together for a
common penetration through a custom cap. Alternatively, place close together using
commonly available pipe flashing. Similarly, group the exhaust pipes and place the
two separate groups of pipes at least 3' apart (the closest intake and exhaust pipes
shall be 36", or more, apart). Use the same 12" (minimum) vertical separation for all
termination options. For alternate group terminations, contact the IBC Factory for
written guidance.
Roof top termination kits are approved for use with the boiler model. Installation of the
vertical roof top termination must follow the installation instructions supplied with the
venting material manufacturer. Care must be taken to install the termination kit a
minimum horizontal distance of 10' (305 cm) away from any portion of the building and
a minimum of 2' (61 cm) above the roof line plus the anticipated snow line.

Caution
Vent termination clearances in this section are code minimum, or IBC recommended
minimum requirements, and may be inadequate for your installation. Building envelope
details must be examined carefully. Take action to avoid moisture entering building
structures. Serious structural damage may occur if adequate precautions and clearances
are not allowed for. These precautions apply to neighboring structures as well as to the
structure the boiler(s) are installed in.
Warning
Important!: Maintain at least the minimum separation of exhaust vent termination from
boiler intake air as illustrated in
do so can result in a dangerous situation where exhaust gases are re-ingested with
combustion air. Damage to the boiler can result from a failure to maintain these
separations. Do not use proprietary InnoFlue or PolyPro PPs terminals without specific
approval from IBC.
