B Flame does not ignite Air in the combustion gas line When connecting or replacing the combustion gas bottle make sure that no air penetrates into the combustion gas supply line. Air which has penetrated the gas supply line results in the flame in the analyzer going out.
Page 338 AO2000 CONTINUOUS GAS ANALYZERS OI/AO2000-EN REV. B Failure of instrument air supply Shutting-off gas supply if instrument air supply fails It must be ensured that the gas supply to the analyzer module is shut off if the instrument air supply fails. As a rule, this is ensured by installing a pneumatic shut-off valve in the gas supply line (recommendation) (see page 48);...
