5 - If called for by point. 3, dismantling and cleaning of the combustion chamber.
6 - If called for by point. 4, dismantling and cleaning of the burner jets.
7 - Visual check of the primary heat exchanger:
-check for overheating in the blade assembly;
-clean the exhaust fan if needed.
8 - Adjustment of the flow rate of the gas: flow rate for lighting, partial load and full load.
9 - Check of the heating safety systems:
-safety device for maximum temperature;
-safety device for maximum pressure.
10- Check of the gas safety systems:
-safety device for lack of gas or flame ionisation (detection electrode);
-safety device for gas cock.
11- Check of the electrical connection (make sure it complies with the instructions in the manual).
12- Check of domestic hot water production efficiency (flow rate and temperature) 13- General check of the combustion
system.
14- Check of the general performance of the unit.
