METAL-FACH Heating Technology

Boiler connection to the electrical installation
(Installer)
The boiler is designed for connection to 230V/50Hz. The installation should be carried out by a qualified person.
The connection socket 230V/10A with earthing should be easily accessible. Boiler power supply and boiler room
lighting should have a different circuit.
Completion of the installation and the heating test must be recorded in the Warranty Card. The completed
Warranty Card should be sent to the manufacturer's address by the user in order to register the user in the
company's system.
NOTE!
The first start-up of the boiler must be carried out only by a service technician trained by
the manufacturer, with a valid certificate of METAL-FACH Authorized Service Provider,
METAL-FACH Distributor or a person holding a SEP license up to 1,5 kW.
NOTE!
All pumps, mixer, relay, igniter etc. are not included in the controller.
Connection of boiler to chimney
(Installer)
Smoke ducts
The purpose of flue pipes is to reliably carry exhaust fumes to the outside and to draw in air for fuel
combustion. The chimney draught required for this depends on:
●
the temperature difference between hot flue gases and cold air,
●
the effective height of the chimney,
●
a chimney section not less than 20 x 20 cm,
●
the execution of the chimney (as smooth internal surfaces as possible) and the tightness of the joints.
The effective height of the chimney is the height difference between the highest hearth and the exit of the
chimney. The effective height of individual chimneys must be at least 4m and common chimneys for solid and
liquid fuels at least 5m. The height difference between two fireplaces must not be greater than 6.5m. In the case
of sloping roofs, the chimneys should terminate at the ridge (the highest point of the roof), in an area of free
wind flow. This avoids draught disturbance. The position of the building in relation to other buildings must
always be taken into account.
