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 by-products of the discharge/ventilation

system.

14- Check of the general performance of the unit.
