Ecoflam Blast Tube 174mm x 90mm 65320256

The Ecoflam blast tube is the cylindrical extension fitted to the burner head that carries the combustion air from the fan into the combustion chamber. Its length and diameter set how far the flame sits inside the chamber and how the air is delivered around the nozzle, so both dimensions matter when replacing one.

This example measures 174mm long with a 90mm diameter and is listed by Ecoflam under part number 65320256. The supplier lists it against the M1304 MINOR and the BFB01003/002 burner reference, so it is intended for that burner family rather than as a general-purpose tube.

• The tube is distorted, burnt back or cracked at the hot end after a sustained flame fault.
• Heavy carbon or soot build-up on the tube that cannot be cleaned back to bare metal.
• Flame shape or quality has changed and combustion readings cannot be brought into range by nozzle, air or pump adjustment alone.
• The tube no longer seats squarely on the burner head, or the locating fit has become loose.
• Corrosion pitting or thinning on the tube wall after long service, particularly on older oil-fired installations.

• Confirm the burner model and the reference marked on the existing burner match the M1304 MINOR / BFB01003/002 listing.
• Measure the old tube before removal if there is any doubt, and compare the 174mm length and 90mm diameter against this part.
• Check whether a gasket, seal or fixing kit is required to refit the tube on your particular burner; these are separate items.
