Flue systems SGS
Installation options
B23
C33
C13
A SGS water heater should be installed according category B23,
C13, C33, C43 or C53*.
* All SGS are also approved for installations where the unit is supplied
without venting materials (C63).
SGS 100
Concentric flues
It is not permitted to use more than the specified number of
bends, even when the duct is shorter than the maximum
length. A 45° bend is equivalent to a 90° bend.
C53
C43
Flue systems SGS
Minimum space requirements
SGS 28-60
SGS 80-100
Parallel flues
- The maximum permissible length should be reduced by the
equivalent length of each bend. (Note: for a parallel installation
this means that 3 changes in direction amount to 6 bends
(3 in the supply duct and 3 in the flue).
- The maximum length also applies if a parallel installation has
different supply and flue duct lengths (B23, C53).
- Combined flues (C43) shall be fitted with a condensate drain.
Note: horizontal flue runs must be installed with a fall of at least
5 mm per metre.
