These flues on non-condensing boilers were designed to worked under a negative pressure as the flue gases temperature was very high (150-240 ) causing a significant draft in the flue. This meant the flue did not need to be sealed and often fitted with stabilisers and installed in sections just pop-riveted together because a correctly sized flue is unlikely to leak or spill.Get Price

2019/11/5 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.Get Price
