You’ll need to decide whether you want to terminate the chimney through the roof; eliminate the appearance of chimney pipe; or go out through an adjacent wall and up. Once you decide on the route, you can purchase a kit for the type of installation you are planning. Now you can stop chimney draughts and reduce chimney heat loss with a Chimney Sheep! In my case I built up a scaffolding up over the chimney to allow me to feed it down from above. Sometimes weep holes are placed at the bottom of the chimney to drain out collected water.
It is also important to have an adequate damper opening size to allow smoke to easily pass from the fireplace area into the flue area. Refer to attachment 1 , which is a chart showing the ratio of the fireplace opening to the flue size based on the height of the chimney. If you do have a chimney fire, have the chimney inspected and repaired if necessary before using the system.
Raised panels, mortise and tenon joinery, and a beaded backboard make this woodworking plan a beautuful replica of an old chimney cupboard. The type of flue you install (or already have) will dictate the type of fire you can fit, so it is important for self-builders to choose their fire first and match the flue to this. Many variations of fireplace design are available and your choice may be influenced by local or regional emission requirements.
The extension of a sheet metal shroud, or corbelling of the brick structure of the chimney that extends outward slightly over the fire, cuts off the amount of ambient air drawn into the chimney and helps the chimney draw smoke more strongly. So your first order of business is to have an expert, certified chimney inspector examine the chimney and flues to find the defects and hazards. A conventional masonry chimney consists of clay tile liners surrounded by a brick, block or stone structure. Used by building and design professionals to make minor or major changes to the plan.
Standard Cleaning – This is the standard or normal cleaning method and involves the use of brushes to clean the chimney walls. As describe in a previous section, the flue size opening must be within approximately 10% of the size of the fireplace opening. If you already have or plan to vent a fireplace insert or hearth stove into your fireplace chimney, we highly recommend installing a properly sized chimney liner from the woodstove to the top of the chimney. Chimney flue size & location: a chimney which has a flue diameter too small will not vent combustion products properly and may be unsafe.
You may also need a septic design unless your lot is served by a sanitary sewer system. Concrete flue liners are like clay liners but are made of a refractory cement and are more durable than the clay liners. Schematic Electrical Layouts – show the suggested locations for switches, fixtures and outlets (not included in JD plans). This type of flue will usually accommodate any type of open solid fuel fire or an open-flued gas fire.
For a prefabricated metal fireplace, the smoke chamber is almost indistinguishable from the rest of the chimney. The term make-up” air is normally used since it describes the volume of air that must be made up inside the building to replace the air passing up the chimney. In general, the area of the flue should be no less than one tenth of the largest open area of the fireplace.
I have also built forges with small chimney flues, and these forges needed to be completely enclosed to prevent ambient air from displacing any smoke in the chimney – or the smoke would actually blow out from the hood opening into the smithy! It is not uncommon for fireplaces and stoves in houses that are surrounded by hills or trees, for example, or that are located in the high-density air that often surrounds large bodies of water, to need more chimney height than the minimum required by code.
