IDEAL CONCORD CXC 70 CF NG 238300B The Concord CXC boiler consists of 2 basic parts; a conventional Concord CXD boiler; plus an additional heat exchanger.
The Concord CXC boiler body is constructed from cast iron sections, insulated by a foil backed fibre glass blanket. It is mounted on a sheet steel combustion chamber.
An aluminiumised mild steel flue collector hood and stainless steel condensate sump is fitted on top of this heat exchanger. The sump supports the secondary heat exchanger which is constructed from aluminium finned tubes between aluminium and cast iron headers. This heat exchanger is also insulated by a foil backed fibre glass blanket.
Above the primary heat exchanger an induced draught fan is fitted capable of overcoming the resistance of a 30m length of 6" flue pipe. The boiler is supplied with header pipework between the primary and secondary heat exchanger.
Within this pipework, a "shunt" pump is provided to ensure an adequate flow through the primary heat exchanger, independently of the system pump. This also ensures that a sufficient temperature is maintained in the primary heat exchanger to prevent corrosion.
