Boiler Repairs and Service

There are still many older, reliable and safely operating heating boilers throughout the community, which must be regularly serviced, maintained, and repaired to keep them working safely. Particularly open flued boilers, for example, the Ideal Mexico CF80, or Baxi Bermuda 401 back boiler unit/Fire. This is because, apart from lint building upon their air filters, the flue can become blocked, resulting in products of combustion (fumes) entering the room.

Routine servicing would include cleaning the appliance in general, particularly the lint arrestors, heat exchanger, burners, and injectors. Checking the gas rate, operation of the flue, and ventilation provision is vital. The ventilation requirement for open flued appliance’s rated over 7kW net input is maximum net-input in kW -7 x5 = cms.squared of free area ventilation direct to the outside air.

Checking the operation of the Flame Failure Device (FFD), thermostat(s), ignition components, etc. helps to ensure the appliance is properly maintained. Installing Carbon Monoxide alarms is recommended by Gas Safe register for all gas appliances; and in my opinion, particularly important where open flued models are installed.
