7.6.3 C43/C53/C63 systems
The length of the air inlet and flue gas outlet is the same for C43, C53 and C63 systems as
for C13 and C33 systems:
Refer to C13/C33 concentric systems for the maximum pipe lengths of concentric
systems.
Refer to C13/C33 parallel systems for the maximum pipe lengths of parallel systems
and non-concentric systems.
Note
Only use a C43 venting system when the common duct is a natural draught chimney. The
common duct is part of the building, not a part of the system.
Note
In a C53 venting system the flue gas terminal must be CE approved and must comply to
the EN 1856-1 requirements.
Note
Connect a C63 venting system to a separately approved and marketed system for the
supply of combustion air and discharge of flue gasses.
The flue gas terminal must comply to the EN 1856-1 requirements. The maximum
allowable recirculation rate is 10% under wind conditions.
Contact A.O. Smith for more information and/or part numbers of the C43, C53 and C63
venting systems.
Concentric systems
Refer to the table for the correct pipe dimensions of the C43, C53 and C63 concentric
systems.

Refer to C13/C33 parallel systems for the A.O. Smith part numbers. The same parts can
be used for the C43, C53 and C63 parallel systems.
Use the "adapter box concentric to parallel - water heater side" (part number 0312209) for
C63 parallel systems.
