Installing the flange with tube
DANGER
Hazard through hot, explosive or toxic flue gases
Hot and/or noxious gases can escape during installation work on the gas duct, depend‐
ing on the plant condition.
b
Work on the gas duct may only be performed by skilled persons who, based on
their technical training and knowledge as well as knowledge of the relevant regula‐
tions, can assess the tasks given and recognize the hazards involved.
CAUTION
Device damage due to defective/missing insulation of the channel in case of hot
measuring channel
b
When the gas duct is hot, insulate the duct and flanges so that the GM32 is pro‐
tected from high temperatures.
