Connect tester to the operating gas pressure test point and check the working pressure with the boiler
operating at full output.
Remove the tester, replace the plug and washer, restart the system, and using soapy water check
the whole circuit for gas tightness.
For a higher level of comfort, particularly where substantial pressure variations in the water supply occur,
set the program close to the draw-off temperature.
Instruct the user on the following points:
Recommend user to read the User’s Instructions.
Instruct user on how to program the Central Heating and DHW temperature and the room
thermostat (if any).
Instruct user on how to top up the Heating system (1.5 mbar).
Demonstrate how the fault codes work for insufficient gas (12 and 17). This is the most common fault code
due to user error. Demonstrate to user how to reset after opening the gas inlet cock.
Recommend that user press reset button (p14 #5) whenever a red fault lamp lights up.
If the red light appears two or three consecutive times, tell the user to write down the fault codes and notify
the nearest Service Center or Installer.
Train user on the various safety devices, recommendations and maintenance operations specified
in the waterheater instructions.
