Safety precautions Safety precautions Gas Safety (Installation and Use) Regulations 1998 It is the law that all gas appliances are installed by a competent person in accordance with the above regulations. Failure to install appliances correctly could lead to prosecution. It is in your interest, and that of safety, to ensure compliance with the law. If you smell gas: B Turn off gas service cock at the meter. B Open all doors and windows. B Do not operate any electrical switches. B Do not smoke.
Safety precautions Combustible materials B Do not store or use any combustible materials (paper, thinners, paints etc.) in the vicinity of the appliance. Health and safety B This appliance contains no asbestos products. B There is no potential hazard due to the appliance being electrically unsafe. B There are no substances used in the construction that are a potential hazard in relation to the COSHH Regulations (Control of Substances Hazardous to Health Regulations 1988).
General notes 1 General notes To get the best from your appliance please read these instructions carefully. Sealed heating systems The appliance is fitted to a sealed heating system which is prepressurised. Your installer will tell you of the minimum and maximum pressure which must be indicated on the pressure gauge. Check regularly that the pressure is maintained and contact your installer or maintenance engineer if there is a permanent significant drop in the pressure.
General notes Clearances Your installer will have provided adequate space around the appliance for safety and servicing access. Do not restrict this space with the addition of cupboards, shelves etc. next to the appliance. Left-hand side Right-hand side In Front Above Casing (Vert. Flue) Above Flue Turret Below 10 mm 10 mm 600 mm 200 mm 30 mm 200 mm Table 1 Room thermostat A room temperature controller may be fitted to control the central heating.
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. For further information contact Worcester Heat Systems Ltd. Technical Services Department.
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. 10 6 720 610 598 GB (03.

Operating the Appliance 3 Operating the Appliance 3.1 Preparation Turn on the gas cock (172). B 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) B Using a spanner, turn square nut until groove is in line with direction of flow (see detail). Groove at right angles to direction of flow = off. Cold water inlet valve (173) B Turn handle so that it is in line with direction of flow.
Operating the Appliance Check the central heating system pressure B The pointer on the pressure gauge (8.1) should be about 1 bar. B 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. B The maximum operating pressure of 2.5 bar at maximum central heating flow temperature must not be exceeded. If the pressure increases to 3 bar then the relief valve (15) opens. 2 3 1 4 0 bar 8.
Operating the Appliance 3.2 Switching the Appliance On/Off Switching on B 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 operating in the central heating mode. 6 720 610 333-04.1O Fig. 4 i If the display alternates between -II- and the central heating flow temperature, the trap filling programme is active.
Operating the Appliance 3.3 Switching on the Central Heating B Turn the central heating temperature control level: to the desired – “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. 5 3.4 Controlling Central Heating B Set the timer to the correct time. B Set room thermostat to the desired room temperature. B Set temperature driven control unit, if fitted.
Operating the Appliance 3.5 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. 6 Control Setting Water Temperature Anti-clockwise limit approx. 40°C approx. 55°C Clockwise limit approx.
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. Hot water is thus available in about 1 minute. ECO mode, button is lit Water is not heated up until hot water is drawn. This means that there is a longer waiting period before hot water is available. 3.
Operating the Appliance Control Setting Water Temperature Anti-clockwise limit approx. 10°C (frost protection) l 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. The hot water cylinder is first heated up to the set temperature. The appliance then switches to central heating mode.
Operating the Appliance 3.8 Frost protection (Combi Appliances) B 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. B Add a suitable anti-freeze fluid to the water in the central heating system.

Tips on saving energy 6 Tips on saving energy Heating economically The boiler is designed to provide a high level of comfort while keeping gas consumption and the resulting environmental effect as low as possible. The gas supply to the burner is controlled according to the level of demand for heat. The boiler continues to operate with a low flame if the demand for heat reduces. The technical term for this process is modulating control.
General Information Hot water A lower setting on the hot water temperature control can result in considerable energy savings. For combi appliances: The on-demand activation using the ECO-button makes possible the maximum savings of gas and water. Now you know how to heat your home economically with the R 30/R 35/R 40 gas condensing boiler. If you have any other questions, please contact your installer – or write to us.
