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 gas pressures: ignition pressure, partial load and full load.
9 - Check the heating safety systems:
- safety device for maximum temperature;
- safety device for maximum pressure.
10- Check the gas safety systems:
- safety device for lack of gas or flame ionisation (detection electrode);
- safety device for gas cock.
11- Check the electrical connection (make sure it complies with the instructions in
this manual).
12- Check domestic hot water production efficiency (flow rate and temperature)
13- General check of the combustion by-products of the discharge/ventilation
system.
14- Check the general performance of the unit.
