  • 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 34 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.
