Insert plate up around pipe and fasten using masonry nails into mortar joints on side and rear – seal against fireplace with silicone and against pipe (if needed) with furnace cement.

Cut on the larger line (including 1” flange), notch all four corners and fold down the 1” flange at about a 60 degree angle. What is the maximum output in kW of your "5kW" wood burning stove? The majority of manufacturers just specify the “nominal output” and this figure means very little in real life. The nominal is a figure the manufacturer chooses to sell the stove at - the stove is capable of reaching at least this output with one fuel load. Nominal means "capable of". But it is not the maximum. The EPA requires re-certification every 5 years. In VC case, the non cat intrepid would not meet the EPA phase II regs, 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). 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.)B. You can bust through the metal somewhere within the hole with an old screwdriver or chisel, and then use aviation snips Go to top of chimney and pull the liner up until the newly-attached vitreous pipe is “up the chimney a little, out of the way" so the closure plate can be fitted. You will need to paint the surface of the inside walls of the recess and one side of the cement board with a PVA mix (3 water to 1 PVA). This is very important as without this stage the bond between wall and board may not be good. If you are considering removing your old fireplace and replacing it with a modern electric fireplace, here’s a handy guide on the average costs of removing the old fireplace. Type Of Fireplace To Be Removed

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. Also I asked why he smashed out the complete housing and not just cut out an area big enough for the stove pipe to go up, then I would have at least had the rest of the damper housing and damper flap to close off a huge section of the hole. This is not always obvious from the ground, but could be a problem. Be sure to get a quote before any work is carried out. For example a dramatic code change occured in 2003 NFPA 211. The manuals with that stove, could be printed in 2001 and they will not update the manual till re-certification occures Fill deep holes in wall with spare mortar or use "bonding" (used before plastering to fill crevices and holes).Before you start you will want to paint the surface of the inside walls of the recess and one side of the cement board with a PVA mix (3 water to 1 PVA). This is very important as without this stage the bond between wall and board may not be good. Same fireplace (middle). Hearth down first. And now you can see the first three 12mm cement-boards. I put the rear sheet in first (cut using angle grinder although a circular saw or jigsaw with a concrete cutting blade will do). On the rear sheet I ensure the factory cut edge is at the bottom.. A closure plate does not need an access hatch for sweeping as the chimney can be swept either via the stove or through a removable sweeping plate on the stove pipe. 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.
