3.3.3 Project planning instructions, flue gas
systems
All applicable regional and country-specific regulations
and laws pertaining to the routing of flue gas must be ob-
ser ved and complied with.
Measure opening
Each supply and exhaust pipe must be equipped with a
test ing vent (already included in the construction sets).
These should be placed in such a way that they can con-
ven iently be reached to perform a measurement.
Length adjustment
The concentric length elements should not be shortened.
Insert the length compensators or reducing lengths to ad-
just to the required lengths.
The basic flue pipes can be reduced in length to fit. How
-
ever, the cut ends must be carefully smoothed to avoid
da mage to the gasket of the connecting piece.
Distance holder
When installing the pipes in a shaft a spacer must be
us ed at least every 2 metres. To provide support for the
chim ney stack the lowest element must be fixed (bearing
rail or pipe clip).
Flue gas temperature
The Hoval flue duct systems E80 PP, E100 PP, E80 Flex
PP, E100 Flex PP, C80/125 PP, C100/150 PP and E130
PP are long-term temperature resistant to 120°C.
Connecting pipes
Horizontal connection lines must be routed with a down-
ward slope of at least 5 cm per running metre of their
length in the direction of the boiler to ensure that conden-
sate can flow back to the boiler unhindered. The whole
ex haust system must be installed so that condensate can
nev er collect at any point.
!
WARNING
The flue gas lines must be secured against
un wanted loosening of the plug connections.
Condensate drain
Condensation water accumulating in the flue
gas pipe can be drained via the boiler.
Chimney shaft
For a concentric chimney connection in which the com-
bustion air is fed through the chimney, the following mini-
mum chimney cross-sections must be observed:
Cross-section 150 mm x 150 mm for rectangular chim-
neys, or Ø 170 mm diameter for round chimneys.
In determining the chimney dimensions the installation of
the spacers should be taken into account.
With simple chimney connections, a grating must be in-
stalled for the purpose of back ventilation in the shaft.
3.3.4 Room air-independent installation
•
When configuring the intake tube, comply with the fol
-
lowing:
- The air intake opening must be freely accessible and
have a protective grating or possibly wind protection
equip ment.
- Always keep the air inlet clear (of leaves, snow, etc.).
- Do not store any chemicals or poisonous substances
in the vicinity of the air inlet.
- Do not install the air inlet adjacent to extractor hood
openings or other air extraction equipment.
Wall bushing
The following only applies to countries in which wall ducts
are allowed:
For C53 construction boilers, the air intake opening for
the combustion air must not be on the opposing wall of
the exhaust opening of the flue gas line.
