the boiler via the combustion chamber or the
inspection port of the flue system.
Danger
If the trap is not full, flue gas can escape.
Escaping flue gas can cause life threatening
carbon monoxide poisoning.
Always fill the trap with water before com-
missioning.

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.
