  • Page 7: Condensing Boiler Installation Requirements

    2 CONDENSING BOILER INSTALLATION REQUIREMENTS The Warmflow condensing boiler can be fitted to most installations using standard practices and techniques. There are however a number of considerations that must be taken into account. All existing systems must be properly flushed to remove any sediment/ sludge in order to prevent any blockage or reduction in efficiency of the boiler.

  • Page 8: Before Fitting A Combi Boiler The Installer Must Check

    Combi boiler. Systems requiring very high hot water flow rates may be better suited with a Warmflow unvented cylinder. 2. That the mains are capable of supplying up to 24 litre/min with a minimum dynamic pressure of 1.8 bar at the boiler.

  • Page 9: General Information

    Regulations Section 6, Part F Northern Ireland and Part L Republic of Ireland. Warmflow oil fired condensing boilers are designed to burn Class C2 (28 sec redwood) kerosene only and to be used on a fully pumped system, and are suitable for connection to sealed heating systems.

  • Page 10: Combi General Requirements

    The heating system should be installed by a competent installer in accordance with the recommendations laid down by the building services compliance guide, OFTEC and sound engineering practice. In order to comply with building regulations, the boiler passport and or OFTEC forms CD10 for installations and CD11 for commissioning should be left with the customer.
