Servicing Inspection of the Boiler
The user is obliged ensure regular annual servicing inspections of the boiler.
When these conditions are not observed the owner cannot clam warranty repairs.

•
Check of liquids leakage from boiler's joints;
•

•
Check of the adjustment of CO
2
of the gas valve (emission), should be performed 1 x per year;
•
Disassembling of the burner and check of exchanger and electrodes state;
•
Check of siphon clogging for condensate discharge;
•
