Please note
Manufacturers instructions must not be taken in any way as
overriding statutory obligations.
Boiler Position
The following limitations must be observed when siting the boiler:
The boiler is not suitable for external installation. The position
n
selected for the installation should be within the building,
unless otherwise protected by a suitable enclosure and must
allow adequate space for installation, servicing and operation
of the appliance and for air circulation around it.
The position must allow for a suitable flue system and terminal
n
position. The boiler must be installed on a flat vertical wall
capable of supporting the weight of the appliance and any
ancillary equipment when full.
If the boiler is to be fitted in a timber framed building it should
n
be fitted in accordance with ige/up/7. If in doubt advice must
be sought from the Institute of Gas Engineers.
Installation conditions for balanced flue operation
(appliance type C)
The Vitodens can be installed as appliance type C13x, C33x, C53x
or C63x to BS5440, for balanced flue operation independent of
the size and ventilation of the installation room.
It may, for example, be installed in recreation rooms, in other
living space, in ancillary rooms without ventilation, in cupboards
(open at the top) and recesses without maintaining minimum
clearances to combustible parts as well as in attic rooms (pitched
attics and ancillary rooms) where the balanced flue pipe can be
directly routed through the roof. Since the flue pipe connecting
piece for balanced flue operation is surrounded by combustion air
(coaxial pipe), no clearances towards combustible parts need to
be maintained (for further details, see the technical guide "Flue
gas systems for the Vitodens").
The installation location must be safe from the risk of frost.
Installation conditions for open flue operation (appliance
type B)
(Type B23 and B33)
In rooms where air contamination through halogenated
hydrocarbons can occur, such as hairdressing salons, printing
shops, chemical cleaners, laboratories, etc., install the Vitodens
only as balanced flue system.
Wall mounted boilers should not be installed in areas subject to
very dusty conditions.
The installation location must be kept free from frost and must be
adequately ventilated.
Provide a condensate drain (combined with blow-off pipe for the
safety valve) in the installation room.
The maximum ambient temperature of the system should not
exceed 35 ºC.
Operation of the Vitodens in wet areas
The Vitodens is approved for installation in wet areas (e.g. bath or
shower rooms) (protection IP X4 D, splash-proof). When installing
the Vitodens in wet areas, observe the safety zones and minimum
wall clearances according to IEEE wiring regulation. The Vitodens
may be installed in safety zone 1, if hosed water (e.g. through
massage showers) is prevented.
