44 Instructions for installation and servicing ecoTEC 839592_127.1.5 Inspection and maintenance work stepsNo. ActivityColumn 1Inspection mustbe carried outeach yearColumn 2Maintenancemust be carriedout at regularintervals – butno longer than5 years1 Check the air flue gas installation for leaks and for proper fixation and ensure it is not blockedor damaged and is fitted correctly, complying with the relevant installation instructions. x x2 Carry out a general inspection of the boiler for dirt and dust and clean as necessary. x x3 Visually inspect the complete heat engine for its general condition and for signs of corrosion,sooting or other forms of damage. If damage is evident proceed to column 2. x x4 Measure the gas flow rate during operation with maximum load (Kap. 5.9.2). If the gas flowrate complies to the Table 5.1 continue with column 1, if not proceed to column 2. x x5Check the gas inlet working pressure (Kap. 5.9.3) operation with maximum load. If the gasinlet working pressure complies to the Table 5.2 continue with column 1, if not proceed tocolumn 2.x x6Check combustion by measuring CO, CO 2 and CO/CO2 . If the values are outside thetole rances of Table 7.1 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 isolator cock and the service valves. x9 Dump 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. If there areany damages repair them before proceeding. x12 Clean the heat exchanger. x13 Check whether the burner is dirty and clean it if necessary. x14 Check the condensate siphon in the boiler, clean and fill if necessary. x x15 Check the condensate ducts in the boiler and clean if necessary. x x16 Install the compact thermal module.

Start the bleeding program P.0. x18 Open the gas isolator cock, reconnect the boiler with the power mains and switch on theboiler. x x19 Perform a test operation of the boiler and heating installation, including water heating andbleed again if necessary. x x20 Check visually the ignition and burner performance. x x21 Check the boiler for leaks of any kind (gas, flue gas, water, condensate) and rectify asnecessary. x x22If you had problems with the CO, CO2, CO/CO2-values in Step 6 before the maintenance, checkthem again now (see Table 7.1). If they are outside of the tolerances of Table 7.1 make anadjustment, see section 7.1.4.x23 Complete the gas commission checklist (benchmark book). x xTable 7.2 Inspection and maintenance steps7 Inspection and maintenance
