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 (overheat thermostat);
-
safety device for maximum pressure (safety valve).
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.
