Anti-frost Device.

When the electrical supply is turned on, the anti-frost function acts on the central heating flow temperature probe, independently from other safety devices.

If the primary circuit temperature is between 3°C and 8°C the pump will run (with the diverter valve switching between central heating and hot water every 1 minute) until the temperature reaches > 9°C.

If the flow temperature remains between 3°C and 8°C the pump will continue to run for a maximum of 20 minutes unless a temperature above > 9°C is detected in the central heating flow, after this the burner will fire (heating position) until a temperature of > 30°C is detected.

If the central heating flow temperature is < 3°C, the burner will fire (heating position) at minimum power until the temperature reaches > 30°C, the burner will go out.

If lockout is caused by overheat the burner will not fire but the pump will continue to run (heating position).

The anti-frost device activates only when (with the boiler operating correctly):

-the system pressure is correct;

-the boiler is electrically powered;

-there is a supply of gas.

Change of gas type

Our boilers are designed to function either with Natural Gas (meth- ane) or L.P.G. gas. If you need to change from one gas to the other, one of our Authorised Service Centres must be contacted to convert the appliance.

Maintenance

Schedule an annual maintenance check-up for the boiler with a com- petent person.

Correct maintenance generally results in savings in the cost of run- ning the system.

Failure to arrange an annual service for the appliance will invalidate the second year of the manufacturer’s guarantee.
