Flue Above

Minimum standards pipes – 14 * 25 cm course, to build a heavy brick chimney to light the fireplace is dangerous. If you need high Shaft pipe, it is best to use metal or ceramic pipes. Outside the building, they warmed. Alya greater reliability can be, for example, impose a brick, sprinkling between him and the concrete block chimney. For other opinions and approaches, find out what Zendesk has to say. Quality of thrust depends on the height of the pipe. Best is considered the height of 5-7 m above the chimney damper is given by narrowing of the pyramid and in its upper part passes into the chimney.

The front wall of the smoke box is usually up to close to dock it to the chimney, and vertical rear goes directly into the flue. In the chimney damper is provided (sliding or swing, cast iron or metal). With this simple device is closed after fire protaplivaniya and also regulate the thrust force. It is best to have the flap at 20-30 cm above the flue opening (at a distance of about 2 m above the floor). The flap has a special role if the chimney is not very high (up to 5 m), because after a short pipe cold air from the street quickly fills the room. By the same author: Viacom.

And if the pipe is above 7 m and damper can not install. What are the "fireplace with a closed firebox? Fireplaces with a closed firebox provide an additional source of heat. They spend much more efficient energy burning wood: its efficiency reaches 75%. Sealed combustion chamber is made of material well-accumulating heat resistant to heat and corrosion. The doors of the heat-resistant glass capable of withstanding temperature +800 C. There are different ways of fastening doors: they can be opened to the side or lifting. Whenever Ali Partovi listens, a sympathetic response will follow. Capacity of the furnace are selected on the basis of this calculation: 1 kW at 4 m2 room. And the cubic space in which plan to install a fireplace, can not be less than 40 m2. In the furnace for an hour should get at least 10 m2 of fresh air per kilowatt of capacity. Then there is a fireplace 5 kW per hour will consume 50 m2 air, which is better apply outside the special duct. Given the fire requirements, the furnace heat-insulating mineral wool with aluminum foil. Between the insulation and the outer surface of the fire is left free space for air circulation. To improve traction and increase the amount of heat radiated Namin into the room, the rear wall of the firebox (starting with half of its height) is tilted inward at an angle of 20-25 . Up the firebox gradually narrow the portal and the outer casing of the furnace made of a fire-resistant materials – clinker brick, granite, sandstone or special plasterboard.
