    Regulations Section 6, Part F Northern Ireland and Part L Republic of Ireland. Warmflow standard efficiency boilers are designed for use only on fully pumped (sealed or open-vented) heating systems and to burn Class C2 kerosene and Class D gas oil. Note that with class D gas oil the flue MUST exhaust at more than 2m above the surrounding ground level.

  • Page 8: Combi General Requirements

    1.3 Combi General Requirements The boiler will have a DHW priority when both domestic hot water (DHW) and central heating (CH) are selected. So if the flow switch is closed or the heat store has not been satisfied the entire output of the boiler is directed to DHW before the boiler will switch over to CH.
