1. Fitting a wood burning stove does not require a professional to do the installation, but it is recommended by us at ChimFit. All work must however comply with part J of the building regulations.
2. This is a simple guide from ChimFit on how to install a stainless steel register plate, other heating appliances and flue manufacturers may have different instructions for their products and so, if in doubt, read their instructions where possible.
Install a steel frame to hold the chimney register plate. The register plate’s purpose is to stop loose objects falling from inside the chimney into the fireplace and helps keep the wood burning stove clean as well. Another benefit is that it keeps the flue insulation in place. It closes off the chimney stack and stops any smoke getting back into the room. The register plate must be be made of a non-flammable material and fit round the wood burning stoves flue pipe while blocking off the opening to the chimney stack.
Some people use fire proof board for register plates because it is easy to cut to measure, very light and easy to position. Many people prefer however to buy a pre-cut steel register plate with access panels. Which once again Chimfit can recommend a retailer for; this is useful in case of a requirement to get access to the chimney for cleaning and other needs.
Register plates can be bought from a supplier that Chimfit can recommend. You will need to install a frame or some other means of holding the register plate in place however. The next step is fitting the stove pipe to the top of the wood burning stove. Having measured the distance from the top of the stove (inside of the flue outlet) to a point at least 1 cm above the top of the register plate frame, you can cut the flue liner and the wood burner stove pipe to length.
An adapter is used to join the top of the flue pipe to the bottom of the flexible flue. Sit the flexible liner into the adapter and make sure it is located centrally. Tighten the adapter to hold the liner in position and to secure the adapter to the liner.
The register plate can now be fitted into the steel frame. The offcut of the stove pipe can be used as a template by drawing a line round it. This circle can be cut out using a jig saw for example. This is done for the two parts of the plate surrounding the stove pipe and straight lengths are fitted to fill any gaps. Fire cement can be bought from Chimfits recommended retailers. Seal the joints and gaps of the register plate with some fire mastic.
