Item #2: 4- inch Backow Preventer - There are two functions available for
this adapter, which can be connected with the micro-boiler and category III
venting and prevents the back-ow of air through the exhaust vent. This helps
prevent harmful exhaust gases from entering the home, as well as helping to
prevent the micro-boiler from freezing in areas where cold air can be blown
or drawn into the exhaust system. Install this adapter in accordance with the
installation instructions that are packaged with the adapter and any applicable
codes.
Item #1: 3- inch Concentric PVC Termination -
Used when terminating direct-vent (seal combustion)
systems, with boilers that require a 3 in. (76 mm)
intake and a 3 in. (76 mm) exhaust. This concentric
termination provides the convenience of only having
to make one penetration through a sidewall instead of
two separate penetrations for the intake and exhaust
piping. The termination includes a bird screen,
restricting small animals, pests, and foreign objects
from entering into the vent system.
