JOANNES 204160 flame tube for AZ 3/L oil burner – 184 mm

The JOANNES 204160 is a flame tube or combustion tube for the long version of the Joannes AZ 3/L or OIL 3 oil burner.

The flame tube is installed at the outlet of the burner and directs the combustion air and flame into the boiler combustion chamber. As it is directly exposed to high temperatures, it is manufactured from heat-resistant metal.

The specified catalogue length is 184 mm, corresponding to a measured length of approximately 185 mm. The internal diameter at the burner connection end is approximately 80 mm, while the outlet opening has a diameter of approximately 63 mm.

This is the long flame-tube version. The standard short Joannes AZ 3 burner uses a different replacement part.

Important: Before ordering, compare the burner code, tube length, both diameters, flange shape and outlet design. This product is intended for the AZ 3/L or OIL 3 burner with a long flame tube.

Important catalogue information: Position 28 in the exploded diagram identifies the flame tube with article number 204160. Position 118 identifies the burner mounting flange and is not the designation of this flame tube.
