The Stove Box comes in four fixed sizes, SB1, SB2, (adjustable) and Blazer and SB4 (rigid). When installed, the stove box sits on the hearth and it is sealed before any fireplace is placed in front.
Use when there is an existing chimney breast. This is the most popular way the Stove Box is used, as many houses have a chimney. This will have a chimney stack with a pot on the top, and most likely would have had an open fire in it at some time.
Use when there is no chimney present. With many houses not having a chimney and a stove is required, there are various options in a room with no flue or in some cases a class 2 flue, which is not suitable for a multi, gas, or wood burning stove.
Use when there is no chimney present. This option is for a house with no chimney, but the flue cannot go up through to the roof for various reasons, then a false chimney breast is built, the stovebox is inserted and the twinwall goes up only to the first metre above the top of the box and then at an angle out through to the exterior up to the recommended height.
