Inset Wood Burner suggested safety and installation guidelines
 

Masonry Chimneys
Masonry chimneys should have a flue liner to help reduce the possibility of the masonry absorbing creosote. If the flue liner in your chimney is cracked or damaged, it may allow creosote to accumulate and heat to escape. This could increase the chance for a chimney fire. Several products are available to reline your masonry chimney and repair a damaged flue. Before you hire someone to reline your chimney, consider these points:

1. Has the relining product been tested and listed by a nationally recognized testing laboratory?
2. Ask the contractor/dealer who will install the liner if they have been trained in this process and how long they have been installing this type of liner.
3. Ask your local code authorities (such as your building or fire prevention officer) if they accept or approve the liner you choose.

These types of solid fuel burning appliances should have the
vent directly connected to the flue of the chimney.
This "positive connection" is intended to reduce the
creosote accumulation in the flue. An example is shown above.


Chimney Maintenance
All chimneys (metal or masonry) require special care so smoke and flue gases are properly vented. Have your chimney inspected and cleaned before each heating season. Some of the things to look for include the items in this picture:

Besides having your chimney inspected, you should also have it cleaned regularly to reduce creosote. Creosote accumulates in stovepipes and chimneys and may ignite unless it is removed periodically. Creosote is mainly caused by:

* Slow smoldering (smoky) fires.
* Cool surfaces (such as exterior chimneys).
* Burning unseasoned wood.

Creosote buildup varies with the type of fires you burn, heater design, draft and the type of chimney. A rule of thumb is to clean a chimney whenever there is more than 1/8-inch to 1/4-inch of creosote. At the very least, you need to clean the chimney on an annual basis, before the start of the heating season. Your chimney may need to be cleaned more than once per year depending on your individual use. Chemical chimney cleaners are generally not effective in reducing creosote buildup.
