5 Commissioning and Testing5.2 Venting the BoilerFig 5/Be) Open valves (A) and (B) and vent at mains pressure, until the sound ofescaping air cannot be heard.f) Close valves (A) and (B), and open the primary isolation flow valve.38
5 Commissioning and Testing5.3 Venting the Heating Systema) Close the gas shut off valve and start the control unitb) Use and simultaneously to activate code 1 and use + _toactivate the venting program via coding address 2F:1(See fig 5/A).c) Under this coding the diverter valve is opened and closed for 20 minutes toassist venting and the display will show EL in Constant temperature mode.Weather compensated mode will show ‘VENTING’. After 20 minutes thecoding will automatically return to 2F:0.d) Check the system pressure and top up if necessarye) Press and simultaneously to deactivate coding 1 and returncontroller to normal operation.f) Disconnect the filling loop flexible hose.Maximum Heating Output Adjustment (if required)The gas control is fully modulating and will normally facilitate a rapid heat up at maximum outputfollowed by a continually controlled heat output. If the system has a particularly low heating loadit is possible to restrict the maximum heating output to prevent short cycling.To adjust the heating output, proceed as follows.a) Start up the boiler.b) Refer to Figure 5/A. Press and simultaneously until 85 flashes onthe display (= rated output) and appears. On weather compensatedcontrols the display additionally shows ’Max output’c) With + _ buttons select the required value in % of rated output as max output.d) Confirm the set value with.e) Record the setting of max output on the additional data plate included with thetechnical documentation. Affix this data plate next to the original data plate on topof the boiler.f) Ensure that the new maximum output is sufficient to cope with the demand.39
