While these boilers are supplied with type ‘B23’ flue configuration (open chamber and forced draught), in order to allow flexible siting, the configuration can be changed to type ‘C’ (room sealed) with the use of a special flue adaptor kit.
The boilers can be supplied for use with Natural or Propane Gas (LPG) and are capable of being installed as a single unit or in simple modular formations for even bigger outputs.
