- Page 6 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 7 That any showers being supplied with hot water by the boiler are compatible with this type of appliance (contact Warmflow for further details). It should be noted that the boiler has been factory fitted with an 8 litre/min flow restrictor.
- Page 8 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) kerosine and to be used on a fully pumped system, and are suitable for connection to sealed heating systems.
- Page 9 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.
