General notes With all mains fed systems the flow of water from individual taps will vary with the number of outlets operated simultaneously and the cold water mains supply pressure to the property. Flow balancing using “ball-o-fix” type valves is recommended to avoid an excessive reduction in flow to individual outlets.
General notes Do not allow the flue terminal fitted on the outside wall to become obstructed or damaged. Pump The pump is a fully modulating type to which the parameters have been set by the manufacturer and must not be adjusted. 6 720 610 598 GB (03.11)

Operating the Appliance Operating the Appliance Preparation Turn on the gas cock (172). Press in the handle and turn it anti-clockwise as far as the stop (when handle is in line with direction of flow, the cock is open). Central heating system valves (170) Using a spanner, turn square nut until groove is in line with direction of flow (see detail).
Operating the Appliance Check the central heating system pressure The pointer on the pressure gauge (8.1) should be about 1 bar. If the pointer is below 1 bar (when the system is cold), top up the system with water until the pointer is 1 bar. Your installer will have shown you how to do this.
Operating the Appliance Switching the Appliance On/Off Switching on Switch on the appliance at the master switch (I). The indicator lamp shows green and the display will show the central heating flow temperature, when the appliance is oper- ating in the central heating mode. 6 720 610 333-04.1O Fig.
Operating the Appliance Switching on the Central Heating Turn the central heating temperature control to the desired level: – “Min” setting: 35°C – Low-temperature heating: setting “E” (approx. 75°C) – “Max” setting: 88°C When the burner is lit, the red indicator lamp is illuminated. 6 720 610 333-05.1O Fig.
Operating the Appliance Combination Boilers: Setting the Hot Water Temperature Hot water temperature On combi models, the hot water temperature can be set to between approx. 40°C and 60°C using the temperature control The domestic hot water temperature is not shown on the display. 6 720 610 333-07.1O Fig.
Operating the Appliance ECO mode with demand detection, button is lit The demand detection function enables maximum gas and water economy. Briefly turning a hot water tap on and then off again signals demand to the appliance which then heats up the water to the set temperature.
Operating the Appliance Control Setting Water Temperature Anti-clockwise limit approx. 10°C (frost protection) approx. 60°C Clockwise limit approx. 70°C Table 3 ECO button Pressing and holding the ECO button , until it lights up switches from Comfort mode to ECO-mode. Comfort mode, ECO button is not lit (factory setting) In Comfort mode the hot water tank has priority.
Operating the Appliance Frost protection (Combi Appliances) Leave master switch switched on. If the appliance is to be left for long periods switch the central heating on and set the room temperature controller at 6°C. Add a suitable anti-freeze fluid to the water in the central heat- ing system.
