IBC SL Series Installation & Operating Manual page 36

Warning
Important!: Maintain at least the minimum separation of exhaust vent termination
from boiler intake air as illustrated in
. Failure to do so can result in a dangerous situation where exhaust gasses are re-
ingested with combustion air. Damage to the boiler can result from a failure to
maintain these separations. Third party vent termination kits and concentric wall
penetration kits that do not maintain these minimum separations must not be used.
Improper installation will void the warranty. Do not use proprietary InnoFlue or
PolyPro PP terminals without specific approval from IBC.
Caution
Take care installing Concentric Side Wall Termination kits when the outdoor
temperature drops below 5°F/-15°C. Possible blockage of the combustion air intake
can occur when the outdoor temperature drops below this temperature.
