Pipe lengths
As the resistance of the flue pipe and air supply pipe increases the appliance power will
decline. The maximum permitted reduction in power is 5 %.
The resistance of the air supply pipe and combustion gas flue depends on the length,
the diameter and all components of the pipe system. The total permitted pipe length of
the air supply and the combustion gas flue is indicated for each appliance category.

Assembly:
For all concentric flue systems the following has to be considered:
1.
Fit the concentric flue pipe into the adapter on the boiler
2.
Connect all flue pipes to begin at the boiler and work towards the wall or roof
terminal. Make sure the connection is air tight.
3.
A non vertical flue system must be connected with a minimum fall of 5mm/m
toward the boiler. If the outer pipe has a folded seam this needs to be
installed upwards.
Important:
A wall terminal must be installed levelled
