This low-level flue kit provides the components required to terminate a Firebird boiler at a standard through-wall exit using a 125mm balanced flue system. Suitable for installations where the flue passes directly through an external wall at a low height, the kit includes a terminal guard for added protection and compliance. Its adjustable length range of 380–600mm supports various wall thicknesses while maintaining correct concentric airflow and flue gas discharge.
The components are constructed to withstand external weather exposure and condensate produced by oil boiler flues, ensuring a durable installation. All seals, adaptors and fittings required for a secure connection to the boiler and external wall are included.
