Adjustments
Periodic maintenance is MANDATORY BY LAW and is important
for the safety, efficient operation and long-lasting life of the
burner, while it also helps to reduce consumption and polluting
emissions.
We therefore recommend the user to entrust a professionally
qualified technician to carry out maintenance on the appliance
on an
ANNUAL
basis.
