Pre-inspection of the system
Danger
Incorrect installation of the
ventilation system can lead to
injuries and equipment
damage.
Always observe the following
instructions.
Simultaneous operation with open flue combustion equipment
!
Please note
If the pressure inside the instal-
lation room of the fireplace
drops more than 0.04 mbar,
flue gases may flow back into
the room.
In that case, the installation of
a pre-heater bank (accessory)
or a geothermal heat exchan-
ger is always required.
&
Never operate this domestic ventila-
tion system
together with open
flue combustion equipment (e.g.
open fireplaces or combustion
appliances for solid fuel). A
mechanical domestic ventilation
system and a combustion appliance
for solid fuel (fireplace) can be oper-
ated together if these combustion
systems are supplied with combus-
tion air via a dedicated air duct. This
should be agreed with the local fuel
gas inspector [where appropriate].
Doors to boiler rooms where the
combustion air supply is not inter-
connected with the living space,
must be airtight and must be kept
closed.
&
If the domestic ventilation system is
to be operated
together with the
open flue combustion appliance
(open flue gas fired boiler or fire-
place), no negative pressure must
be created inside the installation
room as a result of the operation of
the domestic ventilation system.
Both appliances must be mutually
interlocked (accessories, see tech-
nical guide). When using other
makes, ensure on-site interlocking.
&
An air pressure or safety pressure
limiter (on-site) can be installed as a
further interlocking option. This
requires the installation of the auxili-
ary PCB (accessory). This inter-
rupts the power supply to the
installation room of the combustion
equipment and switches the appli-
ance off.
