Boiler flue inspection hatches, gas safe technical bulletin 008 edition 3, ACS revision boiler flues

Derek in the final part 3 of 3 on ACS Revision on boiler flue system takes a look at gas safe technical bulletin 008 on the use of boiler flue inspection hatches that are needed when a boiler flue is boxed in or in a void.

Super simple explanation. Thanks for helping us all out pal. Wish I could remember it all haha 👍

What about if the flue boxing is smaller than 300mm so you can’t fit the correct size hatch?

Can you clarify what you mean at 7:35 what happens or what you do if you have less than 20.6 oxygen. I thought that meant it would fail it’s flue performance test? 🤔 thanks!

Does it still need access if there isn’t a joint in the void? And what intervals would they need to be? I think you can get a 4m length of flue now from some manufacturers, thanks for the content 👍🏼

what is the score if the purpose built void is only 250mm square and the flue does not have any joints because it is only a 2mtr straight run to the outside?

Keston twin flue system 50mm mpvc does this fall in to flues in voids considering its a welded pipe

I have a baxi duotec in a flat where the flue goes into a communal coridoor to the outside. They have put an access panel in and I can check the joint, but it's not correct size. I at risked it last year and the landlord of the building has ignored my notice, and other companies have also reported same issue. I'm due to service again soon, any advise welcome Derek 👍.

Good afternoon, great YouTube content.
Always look forward to a new YouTube upload from Derrick at Tomkat.
Anyway, I don’t like to go off track, but I would be very grateful if any experienced gas engineer can give me some advice.
A few years ago when I was gas training, my gas trainer told me that a combi boiler can be installed in zone 2 of a bathroom - only if there is nowhere else in the property to install it (I presume that he meant that’s ok if the boiler is in a purpose built cupboard with RCD, or if the boiler manufacturer gives permission to do so) ?
Anyhow, I can’t find this info anywhere? Be great if somebody can point me in the correct direction.
Thanks, N
