MIs may say differently though mate and MIs are like God.
I always just put on what ever I've been given so baxi supply 1 per length plus 1 for the vertical terminal so I'd put 3 on that if it still feels loose I'd chuck another on.
I always thought it had to be 1 per length and every change of direction but I have no idea where that came from so don't quote me on that as I may of just dreamt that.
And I also thought you couldn't use banding anymore. Was told that by a bg inspector when I subbed to them years ago and also by the gas safe inspector when he saw it on the van.

No they are not. Regs are legally superior to MI’s contrary to the well held assertion.
Manufacturer instructions over rule regs
What world are you living in?
Always have and always will.
The real one. Where one does not assume a statement is true because it is oft repeated
No. They don’t.
Absolutely 100 % happy for him to do that.
HaHa. I was waiting for that, and I will. But I am not at home at the moment.
But, for now, a Regulation is exactly that.. And is part of Law. That is not to be confused with Standards, which are not. A manufacturer, or,indeed an engineer, can use a method not in the Standards - but may be called upon to explain why their methodology is as or more apt.
Say what?
What has that got to do the MIs?

Realistically, does this scenario happen often? How many times has someone came across a situation where by the regs it was wrong, but right by the manufacturers instructions?
Surely manufacturers are required to produce their appliances so they fully comply with our regs and not just used as a guide?
I would say though that regarding the flue in this thread. The "standard" would be to clip at every change of direction and just before if leaves the roof. But if the manufacturers produced their flue so that when pieced together it was rigid, and they stated only 1 clip at the exit was needed, then this would be acceptable.

MIs cannot over rule Regulations. They can offer an alternative to Standards, but must be demonstrably be at least as effective.
So basically what you are saying is that regs say 1.8m but if MIs state every meter or change of directions this can be ignored and 1.8m can be used?
So if MIs said every 1.2m you would ignore and use regs?

No. You have to follow MIs, but they cannot over rule Regs. They can obviously demand higher specs, and of course you can work to higher standards.
But my point is that MIs are not superior to Regs, which is what folk keep saying.
We will just have to disagree on this one mate.
so lets say
clipping distance
regs every 2m
mi every 1m
you would go off the regs then
quite a bit regs want flues screwed every joint for viessmann this is a big nono as it states in the mi do not screw the flue as with expansion the flues split
