IBC SL 35-199 Operating Instructions Manual page 17

WARNING
In addition to preventing
ingestion of chemical
contaminants, care must
be taken to ensure air
intake terminals are not
installed in locations where
contamination might occur
due to ingestion of particulate
foreign material (dust, dirt
and debris).
WARNING
Intake air openings must be
configured such that rain
or other forms of moisture
cannot enter the air intake
piping system. Otherwise
serious damage to the boiler
may result.
NOTE
Care must be taken when
installing air intake piping to
ensure that a "trap" is not
formed in the piping so as to
allow a build-up of water, and
blockage of intake air.
Such blockage will result in a
boiler safety shut-down.
INSTALLATION
SL 35-199, SL 45-260 MODULATING GAS BOILERS
•
Clearance above paved sidewalk or paved driveway located on public
property: - 7' (2.2m) Note: Cannot terminate directly above a paved sidewalk
or paved driveway that is located between two single family dwellings and
serves both dwellings
•
Clearance under veranda, porch, deck or balcony: - 12" (0.3m) IBC strongly
recommends a minimum of 24" with the SL 35-199 and SL 45-260 to
avoid damage to the structure. Note: Prohibited unless fully open on a
minimum of two sides below the floor.
•
Vents must be installed such that flue gas does not discharge towards
neighbor's windows, air intakes, and/or where personal injury or property
damage can occur.
•
It is important to ensure proper condensate management from vent
terminations. Condensate shall not be discharged in a manner that will cause
damage to external building finishes or components, or infiltrate building
envelopes, including adjacent structures.
1.4.7 "Direct Vent" Combustion Air Intake Piping
There are two basic methods of supplying combustion air to an IBC boiler.
The direct vent option uses piping from the outside to supply combustion air
directly to the boiler's combustion air connection.
