Register plates are used to seal off the base of the chimney (This Register Plate can be cut on site to fit the base size of your chimney stack). The register plate will support vermiculite and stop any debris from within the chimney stack coming down the chimney and hitting your stove.
The register plate and the supporting brackets are made from 1.5mm thick galvanised steel. The register plate can be sprayed to match the colour of your stove pipe. This register plate has a special adaptor suitable for installations which use either 125mm or 150mm diameter flue pipes.
The four supporting brackets should be cut to the length and width of the base of your chimney stack. Drill a number of holes in the brackets. Now screw them into the brickwork. Cut the register plate to the correct size, taking care that the pipe hole lies vertically above the black stove pipe. Drop the register plate onto the supporting brackets. Now seal any gaps between the brickwork and the brackets/plate using fire cement or high temperature sealant. For 150mm diameter installations simply remove the centre cover ring by unscrewing the two retaining screws.
