dwelling and minimize energy consumption. The room thermostat should not be sited in direct sunlight or close to
any heat source such as radiators. Thermostatic radiators valves may also be used, but should not be fitted in the
same room as the room thermostat.
After the central heating circuit has been installed open all service valves, flush pipes through and check for leaks
before commissioning and introduce the correct inhibitor for a central heating circuit in accordance with BS7593.
Commission the boiler slowly to allow air to escape through the automatic air vent. Remove air from pump using
front screw on pumps.
Pressurize the system to 1.5 bar.
Where the boiler is being retro-fitted to an existing installation, it is equally important to flush the system and
commission using inhibitor to BS7593.
TERMO boilers are fitted with an automatic and manual air vent. The boilers are also equipped with an air-
indicator which detects the presence of air in the boiler. If air is detected and It exceeds the permitted level, air-
indicator switches off immersion heaters and circulation pump remains active, so that air is allowed to escape
easily. Once the air is dispelled the immersion heaters will be active.
3.5. Connection to the electrical mains supply
Before working with the appliance, turn off the power supply (MCB) and secure against restart.
This device must be earthed.
Check that the electrical supply to the building has sufficient current and voltage to supply the boiler and other
appliances to be used.
Miniture circuit breakers (MCB) must be fitted in the wiring prior to the boiler. For MCB ratings see table on page
12.
Measure exact voltage between L and N lines prior to connecting boiler, if it 10% higher than nominal voltage on
appliance, appliance itself can be damaged.
Connect the boiler to the mains using a double pole linked switch
with 3mm contact gap in both poles. There is an RCD switch factory
fitted inside the boiler. Supply cables must be connected to the
RCD switch inside the boiler as shown below. Stretching force of
the network connection is 3,5 Nm.
In order to connect the power supply cable, the power connection
protection cover (1) must be removed by unscrewing two screws
and pulling the protection cover down. The lower protection cover
(4) should also be removed to facilitate access to the wiring points.
The Power cable must be connected directly to the RCD (2), earth
must be connected to a separate terminal (3). After connecting the
power cable, the protective cover (1) must be replaced and securely
fastened.
Upon completion of electrical installation, carry out preliminary
safety checks according to BS7671:2001
Note:
Power cables from Ø6 mm to Ø20 mm must be connected
from the left side of boiler and the protective cover (see 1 above)
must be secured, the power cables in excess of Ø20 mm
Power supply connection
must be connected from the bottom side of the boiler (see 4above) using the provided entry point.
Ensure that the wires are securely fixed.
The appliance must be connected to mains electricity and tested according to current IEE regulations. An NICEIC
inspection and completion certificate must be issued.
All exposed pipework must be earthed according to current IEE regulations
