4.1.1 Regulations concerning installation site
The approval of the relevant building regulations
authority must be obtained for the selection of the
installation site and for the characteristics of the
ventilation and exhaust gas handling systems of the
installation room.
The combustion air fed to the unit must be technically
free of chemicals which contain, e.g. fluorine, chlorine or
sulphur. Sprays, paints, solvents and cleaning materials
and adhesives contain such substances, which can,
during operation of the unit, lead to corrosion under
certain conditions, including in the exhaust gas
installation. If the installation is to take place at the site
of erection, a water pressure test at a test pressure of
5,2 bar should be performed. The equipment
manufacturer must, in this case, issue a certificate to
say that the water pressure test has been performed.
Separation of the unit from structural components of
flammable material by a specified distance is not
required. Since, at nominal heating output of the unit,
temperatures in excess of the permissible temperature
of 85 °C are not created, we recommend the clearances
shown in Section 4.3.
Clearances in accordance with Section 4.1 to 4.3 must be
maintained for maintenance purposes.
If the boiler is to be installed on a flammable floor (e.g.
wood, PVC or similar), the boiler must be placed on an
underlay of non-flammable material.
4.1.2 Notes concerning the heating system and the
installation site
– From the blow-off line of the safety valve, there must
be a drain pipe with inlet funnel and syphon fitted by
the user to a suitable drain (connection to the waste
water system) within the installation room. The drain
must be visible!
– The safety temperature limiter fitted to the boiler also
serves as a shortage of water safety device.
– The switch-off temperature of the boiler in the event
of a malfunction is ca. 110 °C.
A suitable thermostat must be mounted in the heating
feed line by the user if plastic pipes are used in the
installation. This is required to protect the heating
installation from temperature-related damage. The
thermostat can be wired electrically into the plug
location for the plant thermostat of the Pro E system.
– In the case of installation volumes in excess of 15 l/kW
heating capacity, suitable hydraulic protection
switching must be installed.
– The boiler should be installed in a frost-protected room
in the vicinity of the exhaust gas chimney. The
permissible ambient temperature for operation of the
boiler is b 3 °C and + 45 °C.
– When selecting the installation location, the weight of
the boiler, including the water contained within it,
shown in the table “Technical Data” and the type of
chimney construction must be taken into account.
