24kW Morco LPG Condensing Combi Boiler – GB24 IV

This wall-mounted, room-sealed boiler boasts advanced features, including full sequence automatic spark ignition and fan-assisted combustion.

Experience heightened efficiency with this condensing combination boiler, where condensate is generated from the flue gases. Effortlessly managed through a plastic waste pipe at the base of the unit, the condensate ensures a seamless drainage process to a suitable disposal point. Witness the distinctive condensate ‘plume’ at the flue terminal, a visual testament to the Morco GB24 series IV’s high-performance capabilities.

Versatility is at your fingertips with the Morco GB24 series IV, as it serves as both a central heating system and an on-demand supplier of instantaneous domestic hot water. This the latest model from Morco and supersedes the GB24 SIII.

  • This appliance installs and commissions in exactly the same way as the GB24-LPG SIII.
  • 2 years standard warranty.

To flue vertically you will require (RSF345 & RSF346) and to flue horizontally you will need (RSF303). Additional flue accessories and extensions can also be purchased.

Morco standard warranty period is two years from date of commission for the GB boilers and one year for the FEB models and all water heaters. If the appliance is an original fitment in a brand-new caravan holiday home, any problems within the standard warranty period will need to be reported to point of sale for the holiday home, for example the park or dealer. There is no requirement to register warranty with Morco. If the below information can be provided this will help speed up the process:

Model Number of the Appliance - e.g. EUP6 or GB24 IV etc.
Description of the problem - e.g. appliance fails to ignite or central heating works but no hot water
The fault code, if the appliance has an LCD display.

For any appliances which are not original fitments in holiday homes, Morco would usually recommend asking the commissioning engineer to reattend and call their technical helpline on 01482 325 456 from in front of the appliance. Please note, Morco may ask for a copy of the commissioning certificate in these cases. Warranty on appliances which were not fitted into holiday homes at manufacture is parts and advice. For more information regarding the warranty on individual appliances, please see the warranty section from within the instruction manual. If you have any further questions regarding Morco's warranty, please contact us.
