Anyone got one of these condensing boilers? Has it got a short connector between the top of the boiler flue outlet and the elbow of the flue kit?
Mine is missing and having real trouble sourcing the part. Grahams say none of the brochures or information online shows such a part.Even their contact for Bosch has provided a part number that does not exist.The guy who was trying to source tha part has gone away and noone else can find any information so i am stumped.

Why is everything so difficult??
