Mazona 5" Chimney Closure/Register Plate Kit 950mm x 400mm

Product Information

Adaptors have various lengths of “nose”. A long-nose adaptor can be useful as it adds "telescopicity" to the system (I think I just made up a word). Warning: The height of the boards is critical: you want the top of the rear board to be completely horizontal and 15mm below the height of the lintel.

When you cut out your hole you can afford to have it a reasonable size. As long as it is smaller than the square and there is material left for the four screw holes to work then all is good. A closure plate is used when a chimney liner, containing flue gases, is present. The closure plate is therefore only required to seal the chimney for cosmetic reasons, to stop soot old soot falling on the stove but also to stop heat disappearing up the chimney and being wasted. If a closure plate developed a fault (e.g.hole) smoke could NOT enter the room as the smoke is contained in a chimney liner. The traditional method is to screw metal right-angle to provide a “shelf”. If your recess is nice and rectangular with smooth walls then this is easier than if the reason is “all over the place” (e.g. stone). Though of course, how much maintenance your setup requires depends on the type of fireplace you have.I never thought to ask the installer to do this because I was new to inserts at the time it was put in. (Though not new to wood heat in general, having grown up with a wood stove as our sole source of heat.) Elk, did you write that whole diatribe? Wow......you must have it stored somewhere and break it out.....

The height of the boards is critical: you want the top of the rear board to be completely horizontal and 15mm below the height of the lintel. This is because the top edges of these first three boards will provide a shelf, a flange, on which your closure plate will sit (your closure plate will be made of the same board and will slide in to sit on the first three boards). Lay out on piece of sheet metal – layout from center and leave enough room for a 1” extra flange around actual measurements. Before the closure plate design commences I usually connect my “adaptor” to the bottom of the chimney liner (adaptors can have differing lengths of nose and have two methods of attaching to the liner – bolts or self tappers). If using self tappers they will pass through the liner and both walls of the adaptor (choose a length so they only protrude a few mm into the inside surface of the adaptor). Better still buy our adaptor with captive wing nuts. What is the height required between the top of the stove collar and the closure plate if two elbows are on top of each other? 30cm covers this but allow 50cm if one elbow has a soot door. Height above stove is rarely mentioned anywhere for some strange reason but I mention it in my article Heat Shields and Distance to Combustibles for Wood Stoves.I'll try to make it as short as I can. What I basically have is a question about Inswool being used to close up the hole in the flue after the rear of the damper (damper question below) was smashed out (by the installer), the stove was put in and Inswool and only Inswool was used to close the hole in chimney flue.
