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 (see section 8.7.1) for the maximum pipe
lengths of concentric systems.
• Refer to C13/C33 parallel systems (see section 8.7.2) 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.
