ANTI-FROST DEVICE
The boiler is fitted with a device which, in the event that the water temperature falls below
8
˚C the pump activates and runs until a temperature of 18˚C is attained. In the event that
the water temperature falls below
3
˚C, the diverter valve switches to Domestic Hot Water
and the burner fires and runs on minimum power until a temperature of 33˚C is attained.
This device is only activated when the boiler is operating perfectly and
- the system pressure is sufficient;
- the boiler is po
wered electrically;
- gas is being distributed.
Schedule an annual maintenance check-up for the boiler with a CORGI registered
Ser
vice Engineer.
Correct maintenance always results in savings in the cost of running the system.
Our boilers are designed to function either with Natural Gas (methane) or L.P.G. gas. If
you need to changeover from one gas to the other, one of our Authorised Service Centres
should be contacted.
