value. Consult your installer for

RACTICAL TIPS

- If the water is very hard, it is

recommended that a water softener
be added to the system so as to
reduce the formation of limescale in
the boiler exchangers. This will
ensure that the efficiency of the unit
remains the same over time,

reducing gas consumption and
maintenance costs.

- If the boiler should be out of use for

a prolonged period, it is
recommended that the electrical
power supply be disconnected and
that the external gas cock be closed.
If low temperatures are expected,
the boiler and system pipe work
should be drained in order to prevent
frost damage.

- To improve comfort and take full

advantage of the heat produced by
the boiler, it is recommended that an
external (room) thermostat be
installed.

- It is good practice to clean and

service the appliance and central
heating  system every year.
Call an Authorised Service Centre.
