WARNING
Never touch parts that could be hot without temperature-resistant safety
gloves
2.4 Hazard to the device due to purge air failure
CAUTION
The purge air serves to protect the system mounted on the boiler. It shields the
components from hot and/or aggressive gases and dusts. The purge air supply
must therefore be reliably ensured even when the system is stationary. If the
purge air fails, the lens can quickly become soiled and the device can overheat
due to heat accumulation and be destroyed.
The operator must therefore ensure that:

the purge air supply operates reliably and without interruption,

a failure is detected immediately,

the Compact Flame Monitor is protected by a valve or disconnection in the
event of a purge air failure.
