Concentric roof flue terminal specifications C33
3.10.4 Parallel connections
The table states the maximum pipe lengths for parallel systems. The maximum
pipe length depends on the chosen diameter.
Warning
Install flue gas discharge pipe runs with a run-off of 5 mm per metre towards
the water heater.
Chimney flue requirements for parallel systems
You must use the longest pipe when calculating the pipe length. For example, if
the chimney pipe is 4 metres and the air supply pipe is 3 metres, use 4 metres
as the length for the calculation. Next, add the L
equivalent
for every 90° and 45°
bend to this 4 metres, in both the air supply and flue gas outlet. The following
practical example illustrates how to use the table.
Practical example of parallel flue gas discharge
Example
The figure shows a SGE 60 installation. This has to be fitted with a 4 m parallel
pipe 100 mm in diameter, plus four 90-degree bends. The configuration must be
checked for compliance with the requirements stated in the table.

1) Parallel systems with diameter of 100 mm. If the maximum total length when
using a diameter of 130 mm is insufficient, a diameter of 150 mm must be
used.
Any diameter enlargement must be carried out on both air supply and
flue gas
outlet.
