Register Plates

What is register plate?

A Register Plate is needed when you install a stove into a fireplace with an existing chimney. The register plate seals off the chimney so that only the flue connection of the stove is passing through it. So what is a register plate for?:

• If you are not lining your chimney then the register plate is essential in order for the stove to actually work or the chimney will not be able to 'suck' on the stove.
• If you are lining your chimney and insulating around the liner with leca or vermiculite (we do not recommend vermiculite as it compresses if it gets damp) then the register plate holds the insulation in place, and hence needs to be securely fixed and strong.
• A register plate also stops heat escaping up into the chimney void - you want the heat in your house, not up the chimney.
• A register plate also stops debris from the chimney falling down into the fireplace and onto the stove. With older masonry chimneys you can get sizable chunks falling down which could be dangerous as well as messy. This is why the plate should be made of metal and not just heat proof board which would break if hit by a falling lump of stone or brick.
