INSTALLATORUSERTECHNICIAN3.15 CASING REMOVAL(Fig 3-4).To facilitate boiler maintenance the casing canbe completely removed as follows:- Remove frame (1) grasping the edges and pullingtowards oneself as indicated by the arrow.- Loosen the 2 front screws (2) and the 2 screwfasteners (3) below on the casing (4).- Pull the casing (4) towards yourself and upat the same time to detach it from the upperhooks.3.16 YEARLY APPLIANCE CHECK ANDMAINTENANCE.The following checks and maintenance shouldbe performed at least once a year.- Clean the flue side of the heat exchanger.- Clean the main burner.- Visually check the fume hood for deteriorationor corrosion.- Check correct lighting and operation.- Ensure correct calibration of the burner indomestic water and heating phases.- Check correct operation of control andadjustment devices and in particular:- intervention of main electrical switch positionedoutside of the boiler;- system control thermostat intervention;- domestic hot water control thermostat intervention.- Check that the internal system is properlysealed according to specifications.- Check the intervention of the device against nogas ionization flame control. Intervention timemust be less than 10 seconds.- Visually check for water leaks or oxidationfrom/on connections.- Visually check that the water safety drain valveis not blocked.- Check that, after discharging system pressureand bringing it to zero (read on boiler manometer),the expansion vessel charge is at 1.0 bar.- Check that the system static pressure (withsystem cold and after refilling the system bymeans of the filling valve) is between 1 and 1.2bar.- Check visually that the safety and controldevices have not been tampered with and/orshorted, in particular:- temperature safety thermostat;- water pressure switch;- air pressure switch.- Check the condition and integrity of the electricalsystem and in particular:- electrical power cables must be inside thewhipping;- there must be no traces of blackening orburning.22 - IE
