Quick Question on Registration Plates

purpleweasel

I Had my Woodburner installed back in February by a HETAS dealer. I decided to go down this route since after looking at installing it myself with building regs since our council now charge £210 + vat it would only save me about £300 if I did it myself. Not worth the risk since HETAS sign the job off on that day and I wouldn't have to deal with those building regs council numptys who haven't got a clue anyway.

I was surprised the way he did the registration plate He attracted two pieces of angle iron left and right of the chimney then rested two pieces of angle iron the front and back of the chimney. He then Put the register plate in 4 pieces, the middle with the pipe adapter to Flexible flue (904 grade), with a further two panels each side, again just placed on the angle iron and unsealed. Having read part J building regs I questioned him whether the reg plate needed to be sealed. He said it didn't need sealing since it was sealed at the stove and at the pipe adapter and therefore it was sealed along the length of the flue.

Is this right? I can't see anything in the part J that says this so I am only going on his word. So If anyone knows this to be true or can point me to a place where I can get a definite answer then please help.

I suppose his explanation seems ok, however if there was to be a failure of the seal on the flexi to clay liner, flue pipe to flexi or indeed the liner itself then you could in theory have a downdraft blow fumes into the room through the gaps in the register plate.

You should have a CO detector as part of your install, just make sure you check it's function periodically.

You could ring Hetas and direct your question to them. They should know and be able to give a definitive answer.
