This high-level horizontal flue kit provides a complete 125mm balanced flue arrangement for terminating a Firebird boiler through an elevated wall position. It is suitable for installations where a standard low-level discharge is impractical or where higher termination is required to meet clearance distances. The balanced system supplies combustion air and discharges flue gases through a sealed concentric route to ensure safe and efficient operation.
Designed with stainless-steel exterior components and factory-matched seals, the kit withstands condensate, frost and weather exposure common around oil boiler flues. All fittings, adaptors and seals are included to deliver a secure, consistent installation compatible with Firebird high-level flue extensions.
