3.6 Fume system
Important
This unit is a "C type" with sealed chamber and forced draught, with air inlet and flue
exhaust to be connected to one of the following flue systems. Before installation, with the
aid of the tables and calculation methods given, check that the pipes of the flue system
do not exceed the maximum permissible lengths. The current standards and local regu-
lations must be observed. It is absolutely essential, to ensure that products of combus-
tion discarging from the terminal cannot re-enter the building, or enter any adjacent
building, through ventilators, windows, doors, natural air infiltration or forced ventilation/
air conditioning.
B
Only a EUROTERM flue system (with respective accessories) must be used
with this unit, as required by BS 5440 and CE standards.
Baffles
Boiler operation requires fitting the baffles supplied with the unit, according to the following tables.
Before inserting the fume outlet pipe, it is therefore necessary to check there is the right diaphragm
(when it is to be used) and that it is correctly positioned. To replace the baffle (rif. 1 - fig. 13), proceed
as indicated in fig. 13.

Horizontal flue installation
1. Define the position for installing the unit.
2. If using standard flue this must be installed level. For extended horizontal flue
lengths over 1m a fall of 3° (55mm per meter) of the flue exhaust should be
incorporated back to the boiler.
3. Make a hole of diameter 10 - 20 mm greater than the nominal diameter of the con-
centric pipe used.
4. If necessary, cut the terminal length to size, ensuring that the external pipe pro-
trudes from the wall by between 10 and 60 mm. Remove the cutting burrs.
5. Connect flue to the boiler, positioning the seals correctly. Seal the flue into the wall
with silicone or sand + cement and cover with wall seals provided.
A
Flue seals should be lubricated with a silicone type grease to prevent damage
(grease not supplied).
Other coaxial connections
fig. 15 - Examples of connection with coaxial pipes ( = Air / = Fumes)
Table. 2 - Typology
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to the figure on the cover. Any horizontal sections of the fume
exhaust must be kept sloping slightly towards the boiler, to prevent possible condensate
from flowing back towards the outside and causing dripping.
A
The horizontal section to be installed with a minimum 3° (55mm per me-
ter) fall back to the boiler
.
