Nordic pipe insulated flue inspection (revision) tee with canted door (hatch) (cleaning tee with door, insulated cleaning tee) is a section of inspection flue used for assessing the condition of the flue and for cleaning soot from the flue. A condensate outlet (with outlet to the side or downwards) is usually added at the base of the inspection. Most often, the next stage (upwards) after the revision fitting is followed by a connecting tee.

For diameters up to 250/350 the door size is 140x210 mm or 140x270 mm. Hatch size for larger diameters in accordance with approved specification.

Alternatively, the condensate outlet, which is removable from below, may be used as a cleaning hatch.

The insulated flue system is safe and convenient to use, and is certified, CE-marked and complies with the requirements of the current EU standard LVS EN-1856-1.
