  • Page 10 Central Heating Detailed recommendations are given in BS6798, BS5449, BS6700 and CP342 Part 2. Pipework not forming part of the useful heating surface should be insulated to prevent any heat losses or possible freezing (i.e. in roof spaces or ventilated underfl oor spaces). Drain taps should be positioned at the lowest point of the system in accessible locations to permit the whole system to be drained down.

  • Page 28 5.01 Adjusting the pressure and fl ow rate to the main burner This boiler operates on the fl ame modulation principle. It has two fi xed pressure values, minimum and maximum, which must be as shown in the table (pages 5), whichever type of gas is used. Because correct minimum and maximum pressures are critical to the efficient operation of the boiler it is ESSENTIAL that the following adjustments are carried out by COMPETENT personnel ONLY.

  • Page 30 The following operations must be carried out by Corgi registered engineers only. 6.01 Annual Servicing The following should be checked at least once a year: • Water pressure in the central heating system when cold should be about 1 bar. If this is not the case, bring it back to this value.

  • Page 39 8.04 Temperature sensors (thermistors) Identical, but individual, negative temperature co-effi cient (NTC) thermistors are fi tted in the C.H. and D.H.W. outlets from the heat exchanger. As the water temperature increases the resistance in the thermistor decreases. This causes the PCB to reduce the voltage to the modureg, in turn reducing the burner pressure. The wiring for each thermistor is colour coded red for C.H.

The heat rate for the heating function is regulated automatically by the control system according to the characteristics of the internal and external environment (with optional external probe installed), the characteristics of the building and its location. The heat rate for the domestic hot water function is regulated automatically and continuously, to ensure rapid delivery and comfort in all supply conditions.
