Could we install a vent that goes from the space above the damper to the outside? The flue pipe connection to the twin wall chimney must be made in the same room as the appliance. Concrete flue liners are like clay liners but are made of a refractory cement and are more durable than the clay liners. Most of the units inspected by chimney professionals are improperly installed, and a trip to the attic to check clearances is definitely time well spent! Those gases are generally exhausted to the ambient outside air through chimneys or industrial flue gas stacks sometimes referred to as smokestacks.
In the 18th and 19th centuries, the methods used to extract lead from its ore produced large amounts of toxic fumes. Question: Nov 21, Dee said: I have a glass plate hearth on top of an oak floor and under my log burning stove. In other words, draft is simply the natural movement of gases up your chimney as your heating unit draws fresh air into the appliance. But it makes sense to have an inspection of the system for two reasons - the chimney may be very unsafe. If, however, the type and rating of the appliance to be installed is known before the chimney is built and it is unlikely that the chimney will be used for some form of open fire inset or free-standing, then the optimum size of the chimney can be determined for the particular installation.
Either the openings have not been provided, are not large enough or have been simply blocked off. Installing a stainless steel chimney liner or an aluminum chimney liner is an easy way to repair a damaged chimney flue. The height is to ensure the pollutants are dispersed over a wider area to meet legal or other safety requirements. In addition, refractory mortar is specified and seldom used. Chimney Fires Without regular cleaning, a highly flammable substance known as creosote may build up within the flue, making the chimney vulnerable to high-heat fires.

An alternative that I used in many building renovations of older homes where we needed to support an additional Lally column in a basement where the floor slab looked "OK" but was of unknown thickness, was to bed a solid 4" concrete block in concrete right onto the floor surface. Owner will not replace fire box.
They are aesthetically pleasing, long lasting, and add real value to your home. That causes the bottom of the vertical column of hot flue gas to have a lower pressure than the pressure at the bottom of a corresponding column of outside air.
Even minor earthquakes which can barely be felt can result in damage to brick and masonry structures; the damage worsens with time and subsequent tremors. In a fireplace without a chimney cover, the rain water will pool on the smoke shelf, mix with the soot behind the damper, and form an acidic slurry that can destroy the mortar joints.
However, the advantage of a throat damper is that it seals off the living space from the air mass in the chimney, which, especially for chimneys positioned on an outside of wall of the home, is generally very cold. Class A are either an insulated, double wall stainless steel pipe or triple wall, air-insulated pipe often known by its genericized trade name Metalbestos.
Concrete, pumice and clay or ceramic are collectively referred to as masonry chimneys. Apr 24, Roger said: If the firebox is elevated 12" or more off the floor do you still need a non combustible hearth extension or con the hardwood flooring be installed up to the wall that the firebox is located in?

A chimney crown sits on top of the chimney walls and helps shed water away from the entire chimney structure. For a gas fireplace insert you'll want to provide both combustion air and venting as per the manufacturer's specs.
It is an age-old method of regulating draft in situations where prevailing winds or turbulences cause downdraft and backpuffing.
Clay tile flue liners are very common in the United States, although it is the only liner that does not meet Underwriters Laboratories approval and frequently they have problems such as cracked tiles and improper installation.
A throat damper is a metal plate at the base of the chimney, just above the firebox, that can be opened and closed by a lever, gear, or chain to seal off the fireplace from the chimney.
For the most part, however, the design and construction of brick liners has been based on past industry practice due to the lack of available information and knowledge of the physical properties of the brick and mortar, the thermal and seismic behavior of brick liners, and many related characteristics that were not properly or accurately defined.
These liners should be used with wood and multi-fuel appliances. Where a terminal with mesh is used, there is a risk of soot build up, and therefore regular cleaning is required to avoid blockage.Dec 14, · Design and construction of steel chimney liners by American Society of Civil Engineers.

To provide adequate draft and safe venting of combustion products the chimney flue for a fireplace has to be adequate in size or cross-sectional area. This article series provides information about masonry fireplaces. Technical Notes 19A - Residential Fireplaces, Details and Construction Rev [May ] (Reissued Jan.
) Abstract: Brick masonry residential fireplaces can be made more energy efficient by providing a source of combustion and draft air drawn from the exterior of the structure.
