Worcester Bosch Flue Elbow 90 Degree 60mm/100mm 7716191084

The Worcester Bosch 90 degree flue elbow is a concentric flue system component intended for Greenstar condensing boilers. It changes the direction of a flue run by 90 degrees, allowing the flue to be routed around obstructions or to form a raised horizontal run where available space is tight. The elbow is sized at 60mm/100mm, the concentric flue diameter used across the Greenstar range.

Flue gases carry condensate, which forms an acidic residue and must be disposed of correctly through the boiler's condensate route. Keeping the flue path sound and correctly jointed helps maintain the efficiency of the appliance.

• Visible corrosion, pitting or perforation on the elbow body or its joints
• Condensate staining, drips or damp patches around the flue joint or the boiler casing
• Discolouration or heat marking at the elbow, suggesting a compromised flue path
• Physical damage from impact, or a joint that will not seal correctly after reassembly
• Flue gas readings outside the expected range that point to a leaking or displaced flue section

• Check the flue diameter and the angle of the existing elbow against the 60mm/100mm, 90 degree specification
• Confirm the part number 7716191084 or an alternative number matches the component being replaced
• Inspect the flue seals and joints at the same time, as these are commonly disturbed during replacement
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
