Inspection and maintenance 8 We recommend the conclusion of an inspection and maintenance contract with an approved company or installer. The inspection serves to determine the actual condition of the respective boiler and compare it with the specified condition. This is done by measuring, checking and observing. Maintenance is required in order to eliminate any deviations of the actual condition from the specified condition.
8 Inspection and maintenance Always perform the following steps prior to inspection or maintenance work: > Switch off the main switch. > Disconnect the boiler from the power mains by – disconnecting the mains plug or – de-energising the boiler via an isolating device with a contact opening of at least 3 mm (e. g. fuses or power switches). > Further check for electrical isolation of the appliance by use of a test meter. > Close the gas isolation valve.
