Frost Protection

In cold weather the boiler may appear to run when there is no demand for heating (i.e. clocks or room thermostats turned
off).  This is due to the central heating sensor going into frost protection mode.  Once the boiler has reached 14

°

C or more

it will close down until either the temperature again falls below 7

°

C or the clock or room thermostat is turned on.

For this reason we recommend that the electricity to the boiler is left turned on.  If you wish to turn off the electricity to
the boiler in winter you should drain completely the heating and hot water circuits.

Cleaning

The casing requires no special cleaning, a wipe with a soft duster or damp cloth will suffice.

Maintenance

Férroli recommend that the appliance is serviced 

at least once every twelve months

 by a competent engineer.

Gas Supply

It is the law that all gas appliances are installed and serviced by a competent person in accordance with the Gas Safety
Regulations (Installation & Use) 1996, and the manufacturers instructions.  Failure to observe these requirements may lead
to prosecution.

Electrical Supply

WARNING - This appliance must be earthed.

The electrical wiring must be carried out by a competent electrician.

The colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying
the terminal in the plug.  Therefore, proceed as follows:

The wire coloured green and yellow must be connected to the terminal in the plug marked with either the letter E or by
the earth symbol or coloured green or green and yellow.  The wire coloured blue must be connected to the terminal marked
either with the letter N or coloured black.  The wire coloured brown must be connected to the terminal marked either with
the letter L or coloured red.

MINIMUM CLEARANCE

The minimum clearance around the appliance should be as follows:

Sides

5mm

Front

600mm

Below
