Air distribution
Air is distributed through air distribu-
tion boxes with flat ducts (system 100)
in conjunction with suitable branches,
silencers, clean-out covers and air
outlets/inlets.
Routing the air supply ductwork takes
priority over the heating, DHW and
drainage networks to avoid compli-
cated pipe runs.

Thermal insulation
Thermally insulate parts of the air dis-
tribution system that are routed
through unheated areas.
Provide outside air and expelled air
lines with a vapour diffusion-proof
insulation layer.
Provide ventilation air and extract
air lines with an insulation layer of at
least 50 mm thickness.
Preventing flow noise and pressure drop
&Install the air distribution box near
the central device.
&Maintain a max. distance between
the ventilation air and extract air
lines from the device and the air dis-
tribution box of 5 m.
&Install silencers on the ventilation
air and extract air side immediately
above the device (behind the adap-
tor from round to flat).
&Symmetrical ductwork design.
&Short runs, few bends.

Positioning
Location
The ventilation device must be
installed in a dry area, free from the
risk of frost that affords the shortest
possible pipe runs to the ventilation
air or extract air areas. The
Vitovent 300 requires an ordinary
domestic power supply and a conden-
sate drain for the condensate created
during operation.
The Vitovent 300 can be installed
freestanding or wall mounted. The
device must be accessible for mainte-
nance purposes.
Install the remote control unit in a cen-
tral location, e.g. living room, kitchen
or hallway. Install a 2-core control
cable for connecting the remote con-
trol to the ventilation device.
Preferably install the ventilation
device inside the airtight and ther-
mally insulated building envelope.
The following are ideal locations:
&Utility room and domestic offices on
the ground floor
&Wall mounted cupboard
&Cellar
&Thermally insulated long pane attic
room.

Operation with open flue combustion equipment
When installing domestic ventilation
systems together with open flue com-
bustion equipment (open flue gas
fired boilers or open fireplaces),
ensure that the operation of the
domestic ventilation system does not
create negative pressure.
The pressure drop in the installation
room may be up to 0.04 mbar. A
higher pressure drop could cause the
return flow of flue gases, if the ventila-
tion system and the open flue equip-
ment are operated simultaneously. In
such cases, install an interlocking cir-
cuit.
Operation with cooker hoods and extract air dryers
Never link up extractor fans and
extract air dryers and the ventilation
equipment pipework.
Design cooker hoods as re-circulating
or expelled air extractors.
Clearance dimensions
When installing the device ensure,
that its front can be fully opened for
maintenance purposes (min. 500 mm
clearance in front of the device).
Installation conditions
The ventilation air and extract air
device can be installed in any dry
location inside the house that is free
from the risk of frost, where the low
operating noise will not cause any nui-
sance in the living space. The power
supply must be made via a correctly
earthed standard socket with its own
fuse protection and a condensate
drain. The remote control unit can be
fitted anywhere in the house (max.
cable length: 50 m).
Positioning (cont.)
14
5592 914 GB

Installing the device
Position the device level on its rubber
feet.
Note
It may be necessary to provide a
plinth to safeguard the free drainage
of condensate (see page 17).
Hanging the device on the wall

1. Undo the screws in the back of the
device.
2. Secure the retaining brace to the
back of the device.
3. Affix the rubber mounts
supplied Ain accordance with the
diagram to the back of the device.
4. Fit rubber profile Cto the wall
retainer and mount level on the wall
with the screws and rawl plugs sup-
plied.
Fit rubber washers Bsupplied as
anti-vibration insulator between the
wall and the wall retainer.
5. Hook the device into the wall retai-
ner and level out.

Note
Never twist the condensate drain elbow on the device.
Condensate drain via water drain plug
1. Push the condensate drain hose
(1.5 m, supplied in the pack) onto
the condensate drain elbow on the
device.
2. Install the stench trap/siphon.
3. Connect the condensate drain hose
with a constant slope to the on-site
sewer.

Note
Should the condensate drain hose run
partially through unheated rooms,
protect it from frost in such areas (e.g.
thermal insulation or ribbon heater).
Condensate drain via siphon
1. Push the condensate drain hose
(1.5 m, supplied in the pack) onto
the condensate drain elbow on the
device.
2. Connect the condensate drain hose
with a slope and airtight to a siphon
(on-site).
3. Connect the siphon to the on-site
sewer.
Note
Should the condensate drain hose run
partially through unheated rooms,
protect it from frost in such areas (e.g.
thermal insulation or ribbon heater).

Danger
Incorrectly executed electrical
work can lead to injuries and
material losses.
Carry out the power supply
connection and all earthing
measures in accordance with
IEC 364, the requirements of
your local power supply utility,
VDE or national regulations.
The power supply must be made via a
correctly earthed standard socket with
its own fuse protection (230 V/50 Hz).
When installing open flue heating
equipment (type B to TRGI '86/96)
inside the living space or in rooms
connected with several other rooms,
from where combustion air is drawn,
interlock the domestic ventilation sys-
tem electrically with the heating
equipment to prevent both running
simultaneously.
Observe the regulations specified in
TRGI '86/96 , 5.1.22 as well as the
DVGW Code of Practice G 670 [or
local regulations].

Danger
Touching 'live' components can
result in the transfer of danger-
ous body currents.
When connecting the remote
control, isolate the device from
the power supply and safe-
guard against reconnection.
1. Remove the back of the remote
control (wall mounting base D)
from the remote control.
For this, press on the locking tabs
on the bottom of the device.
2. Lead the cable (2-core, min. cross-
section 0.5 mm
2
, max. length 50 m)
through the cable entry in the wall
mounting base. Connect the cable
in accordance with the diagram to
terminals X1 Eof the remote con-
trol.
Note
These cores may be interchanged.
3. Secure the wall mounting base to
the intended installation location.
Note
Installation conditions:
&On an internal wall in the living
space, at a height of approx.
1.5 m from the floor.
&Not near windows and doors.
&Not above radiators.
&Not near heat sources (direct
sunlight, fireplace, TV set etc.).
4. Push the top part of the remote
control onto the wall mounting
base.
5. Connect the remote control cable
in accordance with the diagram to
plug C(plugged into socket Bon
the l.h. top of the Vitovent 300 A).
Note
Never route this cable alongside
230 V cables.
6. Push plug Cinto socket Bof the
OpenTherm BUS connection on
the l.h. top of the Vitovent 300.
Connecting to the power supply
Push the power plug into a safety out-
let with separate fuse protection.
