Some vents, however, may run through a chimney, given that anything else venting through the chimney is contained in a separate flue. They pass from an appliance to a vent or chimney.
There are a variety of connectors available, and the type of connector needed depends on the type of fuel that needs to be vented. A flue is simply a passage for conveying exhaust gases from an appliance to the outdoors. A flue may be a duct, pipe, vent, or chimney. An unlined chimney is technically a flue, even though an unlined chimney is a fire hazard. This can cause confusion, as many view flues not just as a passage for venting, but as a safe passage for venting.
The uneven and porous surface of brick provides a space for combustion byproducts to accumulate. This is a major fire hazard. Rather, chimneys are lined, so the smoke passes over a smooth surface that helps prevent excessive accumulation of combustion byproducts and minimizes the chance of fire. The terms are largely used interchangeably. Traditionally, chimneys were lined by fireclay flue tile. This is more common on an exterior chimney like many fireplace chimneys. There isn't an easy cure for this situation but one solution would be to roll up a newspaper, light it, and hold it up inside the chimney to get the draft reversed then light your fire.
Another option is to install a draft inducer in the chimney or on top of the chimney. A draft inducer is a fan that either pushes up the smoke or pulls it up and out. Draft inducers work very well and generally solve the problem but are somewhat expensive. Draft inducers are available in our Chimney Draft Inducers category. If your wood stove or fireplace only smokes when the wind is blowing from a certain direction you can try a special cap called a Vac-U-Stack or a draft inducer which will generally solve the problem.
For a smoking masonry fireplace a common problem is the chimney flue either too small in relation to the opening or the chimney is not high enough. In effect you have reduced the size of your fireplace opening.
If this simple test works then go to our Smoke Guards category and buy a Smoke Guard for a permanent installation. In other cases your chimney just isn't high enough. An easy and inexpensive way to test if that's the case is to buy some inexpensive black pipe for round chimneys or get some furnace duct work made to size for masonry chimney flues and temporarily add this section to the top of your chimney.
If the poor draft is cured using this method then either buy enough class A chimney pipe to extend the height round chimneys or for a masonry chimney contact a mason to extend it or buy a Flue Stretcher.
