Trianco EuroStar 70/90 Blast tube removal Bayonet fitting

[Graham George]

Hi, I am trying to service a Trianco Eurostar 70/90 oil boiler but I just can not get the bayonet fitting blast tube to turn and release to gain access to the nozzle and electrodes. I have tried using Penetrating oil and a oil filter wrench to turn it, I have tried some heat and some tapping but its just solid. Any body got any ideas that dose not involve stripping the entire unit down and hitting it with a big hammer and hope the electrodes survive.

Do you have correct equipment to set up burner after you have it back together?

I’m assuming you’ve removed the two Allen screws either side of the blast tube? Sorry to sound obvious, but just checking.
