The context does not specify an exact temperature to set the Gabarron MATTIRA MAC15B boiler for hot water. However, it provides a heating temperature range of 8°C to 85°C. For general use, hot water is typically set between 50°C and 60°C, but the exact setting depends on user preference and safety considerations.

  • Page 9 4.9 (a) CENTRAL HEATING CONNECTIONS, DESIGN & REQUIREMENTS This boiler is designed for fully pumped sealed systems only. Treatment of Water Circulating Systems All recirculatory water systems will be subject to corrosion unless an appropriate water treatment is applied. This means that the system efficiency will deteriorate as corrosion sludge accumulates within the system.
  • Page 10: Filling Loop

    Filling Loop A combi filling loop is required for filling of the heating system and replacing water lost during servicing or bleeding and should be installed close to the boiler. The loop should be as shown in the diagram and comply with current Water Supply Regulations.
  • Page 11 4.9 (c) DHW CONNECTIONS, DESIGN & REQUIREMENTS CAUTION: This boiler incorporates a 50 litre unvented hot water cylinder. Installation of this appliance must be carried out by a Competent Person and in accordance with the relevant regulations. In every installation it is mandatory for the Group combination valve to be installed on the mains cold water supply to the boiler.

    7. Check the water pressure downstream of the combination valve is 3 bar in static condition. 8. Check and if necessary, descale the heat exchanger in hard water areas ie. above 200ppm (mg/l). Note: The cylinder is factory fitted with a temperature & pressure relief valve that must not be used for any other purpose or removed.
  • Page 13: General Design Considerations

    General Design Considerations The wall chosen for the boiler should be level and capable of supporting the weight of the unit when full of water as shown in Section 4. The discharge pipework for the safety valves must have a minimum fall of 1:200 from the unit to a safe discharge point.
  • Page 14: General Restrictions

    General Restrictions a. The highest hot or cold water draw off point should not exceed 10m above the Pressure Reducing Valve. b. An ascending spray type bidet or any other appliance with a Class 1 back-syphonage risk requiring a type A air gap should not be used.
  • Page 15: Discharge Pipework

    Discharge Pipework CAUTION: Safety Valve Connections The 7 bar pressure relief valve on the domestic hot water store may discharge boiling water and should be piped to a safe but visible drain point e.g. a gulley where any discharge will not cause damage or injury. ...
  • Page 16: Immersion Heaters

    Pressure & Temperature/expansion Relief Valve Pipework The tundish should be vertical, located in the same space as the unvented hot water storage system and be fitted as close as possible and within 600mm of the safety device e.g. the temperature relief valve. The tundish must be positioned away from any electrical devices.
  • Page 17: Line Strainer

    Line Strainer This is integral within the combination inlet group to reduce the likelihood of contaminants fouling the valve seat. Following installation this line strainer must be cleaned and replaced. This needs to be carried out on a regular basis as part of the annual maintenance/service check.
  • Page 18: Combination Inlet Group

    NOTE: If this appliance is to be installed in other than a single domestic dwelling ie. in an apartment block or student flats etc., the hot and cold water system will need to be disinfected in accordance with BS_EB 806:4 2010 section 6.3 and the Water Regulations.
  • Page 19: Electrical Connections

    WARNING - If water is seen flowing through the tundish, this indicates a fault condition which needs action. If the discharge is hot and continuous, turn the boiler and/or the immersion heaters off, but do not turn off the cold water to the appliance until the discharge is cold.

    Push the button to start the boiler up. The same button will turn the boiler off when pushed again. If the heating or DHW function are not selected the relevant screen will not display a value but just a red dot. 6.3 DOMESTIC HOT WATER OPERATION To select the DHW function push the press the button.
  • Page 26: User Parameters

    The heating setting can be varied between 8ºC and 85°C. The symbol H appears after the 85 value or before the 8 value. If this value is selected, the heating will function in anti-freeze mode. If the setting is higher than the actual temperature of the heating water and the DHW is not connected, the heating will connect and a small red indicator of the consumption of heating resistances will light up.
  • Page 27 6.7 HEATING MODULATION FEATURE The advanced control board on the boiler will automatically modulate the heating output to the demand required to save energy. This function works by the boiler ‘learning’ and anticipating the time taken to reach the temperature level demanded by the external thermostatic control.
  • Page 28: Blocking The Controls

    You can temporarily override the automatically calculated set point. If, for example, you want to use the boiler to the maximum for a few hours even when automatic control mode, you would proceed as follows: When pressing the button, the display will alternatively show the calculated set point and the indication .

Boiler will not start (See Section 6.1.) Heating overheat. Switch tripped. Locate switch and reset. (See Section 7.2) DHW Overheat switch tripped.
  • Page 30 7.2 OVERHEAT LOCK-OUT & RE-SETTING Central heating overheat. If the boiler detects a overheat condition of 100ºC (80ºC if adapted floor heating) in the central heating circuit a safety thermal limit switch will operate and switch the boiler off disabling all functions including DHW production. The cause of the overheat should be investigated.
  • Page 31: Checking Rated Heat Output

    7.3 HEATING SYSTEM FLOW SWITCH – E3 ERROR & SYSTEM BY-PASS REQUIREMENTS If the error E3 appears on the display, the flow switch has detected insufficient water flow in the heating circuit and heat production is disabled to protect the boiler from overheating. The possible causes for this condition are: - Insufficient water pressure in the heating system requiring re-filling to 1.5bar - Pump not circulating or seized.
