2.2.3 - ASSEMBLING THE BOILER
Before connecting the boiler to the D.H.W.
and heating system pipes, carefully clean
the pipes to remove all traces of metal re-
sulting from processing and welding opera-
tions as well as any oil and grease which
could damage the boiler or jeopardize its
operation.
To install the boiler:
-
Fix with tape the paper template to the
wall
;
-
make two Ø 12 holes in the wall and in-
sert the dovels;
-
position the junction points for the con-
nect-ion of the gas supply pipe, cold wa-
ter supply pipe, D.H.W. outlet, CH flow
and return in the positions shown by the
Do not use solvents which
could damage the
components.

template. ;
-
fit the boiler onto the support hooks;
-
connect the boiler to the gas pipe,
domestic cold and hot water pipes, CH
flow and return pipes.
-
connect to electrical supply
2.2.4 - VENTILATION
The boiler must be installed in a suitable room
according to the rules in force and particu-
larly:
FORCED DRAUGHT ROOM SEALED BOI-
LER
(TYPE C12 - C32 - C42 - C52 - C62 - C82)
The
EVE 05 CTFS 24 F
- EVE 05 RTFS 24 -
EVE 05 CTFS 24
are forced draught, room
seal-ed boilers; so they do not need particu-
lar ventilation openings for the combustion
air, in the room in which they are installed.
FORCED DRAUGHT, OPEN FLUE BOILER
(TYPE B22)
If the
EVE 05 CTFS 26 F
is installed in a room
according to the chimney configuration on
type
B22,
the same ventilation requirements
established in paragraphs
Direct ventila-
tion
and
Indirect ventilation
apply.
Direct ventilation:
-
The room has to have a ventilation open-
ing of, at least,
6 cm² /kW of installed input (see input
table on par. 2.7) and, in no case, lower
than 100 cm² and made directly onto an
external wall.
-
The opening has to be as close as possi-
ble to the floor.
-
It should not be possible to close it and it
should be protected with a grate not re-
ducing its usefull ventilation section.
-
A correct ventilation can be optained also
through the addition of more openings,
provided the addition of the different sec-
tions is not less than that really needed.
-
In case it is not possible to make a venti-
lation opening close to the floor, it will be
necessary to increase its usefull section
of at least 50%.
-
If an open fire is present in the same room
it needs an indipendent air supply, other-
wise the installation of a type B appliance
is not permitted.
-
If in the room there are other devices
which need air for their operation (e.g. a
wall exhauster) the section of the venti-
lation opening has to be the properly si-
zed.
Indirect ventilation
In case it is not possible to make a room
ventilation opening on an external wall, it is
possible to have an indirect ventilation, suc-
ting the air from an adjacent room, making
an
opening in the lowest part of a door.
This solution is possible only if:
-
The adjacent room is not a bed room
-
The adjacent room is not a common part
of the building and is not a room with fire
danger (e.g. a fuel deposit, a garage, etc..)
