Exhaust Venting & Air Intake - IBC SL 14-115 G3 Installation And Operating Instructions Manual

WARNING
Exposed water piping and
associated components
(relief valves, circulators,
etc.) should not be in contact
with combustible materials.
Check local codes for required
clearances and/or provide
adequate insulation.
WARNING
DO NOT MOUNT THIS
BOILER TO HOLLOW WALL
STRUCTURES - The combined
weight of the boiler, its water
contents and associated piping
components can exceed 150
pounds. Fasteners must be rated
for this strain, and must be firmly
anchored into solid material that
will support this weight.
Installers are to take all
necessary precautions to avoid
injury during the installation of
this boiler.
DANGER
Do not common vent the SL
modulating series boilers
with any other existing or new
appliance.

Table 2 - Clearance from boiler cabinet
A minimum distance below the boiler of 12" is required to provide clearance for the
supplied condensation trap assembly. More clearance will typically be required to
accommodate associated water and gas piping.
1.4 EXHAUST VENTING & AIR INTAKE
It is important to carefully plan the installation to ensure the appropriate vent materials,
travel and termination decisions are included. Specific attention is warranted to manage
the impact of the steam plume normally experienced at the exhaust terminal of a
condensing boiler. Generally, intake and exhaust pipes should terminate at a rooftop or
sterile wall location, to maximize customer satisfaction. Keep exhaust plumes well away
from all building air intakes including those of neighboring properties.

All venting must be installed in accordance with the requirements of the jurisdiction having
authority: in Canada, Part 8, Venting Systems of the B149.1-10 Code and any other local
building codes are to be followed. In the USA the National Fuel Gas Code, ANSI 223.1,
latest edition, prevails. Where there is a discrepancy between the installation instructions
below, and the code requirements, the more stringent shall apply.
