1.
Undo the trap and fill it with water. There is a risk of
flue gas escaping if it is not filled with water prior to
commissioning.

Refit the trap.
Commissioning the system
Danger
CO build-up as a result of incorrect burner
adjustment or flue gas system leakage can have
serious health implications.
Always carry out a CO test before and after
work on gas appliances.

1.
Check the heating system pressure.
Permiss. operating
pressure
6 bar (0.6 MPa)
Minimum operating
pressure
0.5 bar (50 kPa)
Danger
If the operating pressure is too low, excess
temperatures in the flue system can cause
leaks. Escaping flue gas can cause life
threatening carbon monoxide poisoning.
Ensure the minimum operating pressure
with a minimum pressure switch.
