I am fitting a free standing multi fuel stove and understand the need for a register plate, but I don't fully understand how the plate works. Obviously you need a hole near the centre of the plate to join up to the stove flu, you also need an access plate to gather soot after sweeping. What I don't understand about this is, what stops the soot falling into the stove after sweeping. Can anyone help with this???

Perhaps you have already found this as its first on Google....
Think again about not installing a flu liner as its a PITA cleaning out above the register plate. The soot in the stove can be consumed in your next fire.

Hi Jim
I'm just about to install a woodburning stove and am intrigued by your suggestion not to install a flue liner. Doesn't the flu liner ensure that the exhaust gases get to the top of the chimney good and hot and prevent soot and tar from condensing onto the sides of the chimney flue?
Or am I about to spend a load of money on a flue liner that I don't need?
Regards.
No, its the OP wasn't going to install a liner. My advice to the OP was to install a liner. You've got it right already.

It is illegal to install a wood burner without a metal flue anyway, so you have no choice.
Don't think that is true, care to quote the regs on that.

Jim, thanks for your advice regarding the register plate, but what concerns me is the design of the stove, let me explain. Anytime I do a chimney sweep I do not intend to have to move the stove in any way to access the soot, but because of the design of the stove, it appears the soot will gather in a small recess at the top of the stove, which would make the soot very awkward to remove. Am I to understand, that during sweeping, there is no way of preventing the soot from going into the stove.? Once again many thanks...Tam...
I don't think that is correct. I may have missed something here
Got to make some assumptions here, you have a stove set into a fireplace opening with piece of flue-pipe exiting the top of the stove, going through your register plate and terminating in the void above the register plate.
If so you can sweep the chimney through the stove. I know the Toolstation brush will pass through a stove and 5" flue pipe. No soot can collect inside the stove anywhere below the piece of flue-pipe on top of the stove if you are sweeping through the flue-pipe. You seem to understand the role of the access plate on the register plate but without knowing the stove I can't work out your concern about the small recess at the top of the stove. Perhaps you are sweeping through the access plate and not through the stove? Or have a rear flue? If so you need to use a flue brush.
I did my stove like you indend without a flue liner, legal AFAIU in spite of contrary info in the thread, but its a PITA cleaning out the soot above the register plate so I'm putting in a S/S liner. Then its all sweepable through the stove.

I could, but no time. Yes, its illegal. insisted.
Having researched further these are the relevant regulations, :
Building Regulations Approved Document J (Heat Producing Appliances) 2002,
Technically yes, BUT when I built a chimney out of interlocking clay sections sold for OPEN fires, the BCO rejected it as being not suitable for a wood *stove*. In practice the ONLY retrofittable liners that are suitable are metal ones.
I.e. whilst you are correct in saying that other materials meet the criteria in a new build, almost none of them are suitable for retrofitting. Even a flexible flue was rejected as 'not being suitable for new build'
