33
opening for the air supply is in the same pressure zone as the
discharge.
C Joint air supply and flue gas discharge duct (CLV system).
43
Twin pipe or concentric.
C Separate air supply and separate flue gas discharge duct.
53
Discharge into different pressure zones.
C Free in the market available flue material with CE approval.
63
C Joint air supply and flue gas discharge duct (CLV system).
83
Discharging into different pressure zones.
C Air supply and flue gas discharge duct in shaft or ducted:
93
concentric. Air supply from existing duct. Flue gas discharge
via the roof. Air supply and flue gas discharge are in the same
pressure zone.
The horizontal flue MUST be installed under a 3° fall towards the
boiler (50 mm per metre) and MUST be supported with a minimum
of 1 bracket at each meter length. Best recommended position of the
bracket is just before the joint.

Do NOT mix flue materials from different suppliers.
Only as twin pipe system.
Concentric flue system between the gas boiler and the duct.
Special remark regarding C : The maximum lengths for L1 and L2
53
are related to each other. First determine the length of L1; then
make use of the graph below to determine the maximum length of
L2. For example: if the length of L1 is 2 m, L2 can maximally be 8 m
long.
