Ifdamage is evident proceed to column 2.x x4 Measure the gas flow rate during operation with maximum load (¬ section 10.9.3). If the gasflow rate complies to the ¬ table 10.2 continue with column 1, if not proceed to column 2. x x5Check the gas inlet working pressure (¬ section 10.9.4) operation with maximum load. If thegas inlet working pressure complies to the ¬ table 10.3 continue with column 1, if not proceedto column 2.x x6Check combustion by measuring CO, CO2 and CO/CO2 . If the values are outside thetolerances of ¬ table 12 proceed to maintenance column 2. You must not proceed with themaintenance if a new burner door seal kit is not available.x7 Isolate the boiler from the power mains. Check whether the electrical plug connections andthe other electrical connections are fitted tightly and correct them if necessary. x x8 Close the gas isolation valve and the service valves. x9 Drain the pressure in the boiler on the water side (observe pressure gauge) and check thecharge pressure of the expansion vessel. Top up if necessary. x10 Remove the compact thermal module. x11 Check the integrity of all combustion circuit seals, especially the burner door seal. Ensure anydamage found is repaired before proceeding. x12 Clean the heat exchanger (¬ section 12.3.2). x13 Check whether the burner is dirty and clean it if necessary. x14 Check the condensate trap in the boiler, clean and fill. Flush through all discharge pipe work(ensure route and termination are correct and it is unlikely to freeze up in severe weather). x x15 Install the compact thermal module. Caution: Use new seals and nuts! x16 Replace the hot water heat exchanger if the volume of water is insufficient or the output tem-perature is not reached x17 Remove the impeller sensor, clean the filter in the cold water inlet of the sensor and refit thesensor. x18 Open the gas isolation valve, reconnect the boiler with the power mains and switch on theboiler. x x19 Open the service valves and fill up the boiler/appliance to approximately 0,1 - 0,2 MPa (1,0 -2,0 bar) (depending on the static height of the system). Start the purging program P.00. x20 Perform a test operation of the boiler and heating installation, including hot water generationand purge again if necessary. x x21 Check visually the ignition and burner performance. x x22 Check the boiler for leaks of any kind (gas, flue gas, water, condensate) and rectify as neces-sary. x x23If you had problems with the CO, CO 2 , CO/CO2-values in Step 6 before the maintenance, checkthem again now ( ¬ table 12.1). If they are outside of the tolerances of ¬ table 12.1 make anadjustment, see ¬ section 12.1.4.x24 Complete the Benchmark gas boiler commission service record on the back pages of thismanual. x x12.2 Inspection and maintenance steps
