5 Commissioning and Testing5.4 Filling the Domestic Hot Water Circuit (Combi Boiler Only)a) Open the DHW inlet valve.b) Open all DHW taps in turn to vent any air from the DHW pipework.5.5 Filling the Siphon with WaterFig 5/Ca) Remove the retaining clip and siphon (A)b) Fill the siphon with water.c) Fit siphon (A) and secure with the retaining clip5.6 Commissioning the Boilera) If a clock thermostat is fitted, check that the jumper between ‘L and 1’on plug96 has been removed. (Figure 4/M).b) Lower the control box by detaching the two plastic clips at each end of thecontrol and rotating the control box forwards (see section 4.9)NOTE: The boiler is supplied for use on Natural Gas (G20). If the boiler is to beused on LPG Propane (G31) follow the instructions supplied with the relevantconversion kit before commissioning the boiler.c) Refer to Figure 5/D. Loosen the screw (A) and connect a pressure gauge tothe inlet pressure test point on the gas valve. Ensure the room thermostat iscalling for heat, turn on the gas supply and light the boiler and any otherappliances served by the gas pipe. When commissioning the boiler for use onNatural Gas (G20) check that the inlet pressure is 20±1 mbar (8 in.wg).40
5 Commissioning and Testing5.6 Commissioning the Boilerd) Remove the pressure gauge. Tighten the inlet pressure test point screw.e) Restart the appliance and check for leakage of gas from the pressure test nipple.Fig 5/D: Gas ControlFigure 5/E: Flue Gas SamplingVitodens 200 is set up in the factory for natural gas and can be converted to LPG Propane usinga conversion kit. During commissioning or after maintenance the CO2 level can be checked atthe boiler flue adaptor position (A) as illustrated in Figure 5/E.Subject to Wobbe index, the CO2 content fluctuates between:7.4% to 10.5% for natural gas8.5% to 11.0% for LPG PropaneCompare the actual CO2 value measured at position (A) with the above CO2 value ranges for theindividual gas groups. If the actual CO2 value deviates by more than 1% for natural gas or 0.5%for LPG, proceed as follows:-Check that the correct gas restrictor has been fitted.Check the balanced flue system for soundness.41
