Our boilers are designed to function either with Natural Gas

If you need to change from one gas to another then you should
speak to a Gas Safe Registered engineer or please call Ariston

Schedule an annual service for the boiler with a Gas Safe
Registered engineer.
Correct maintenance always results in savings in the cost of
running the system.
Failure to arrange an annual service for the appliance will
invalidate the warranty of the appliance.
