Elements Of A Perfect Chimney System
Your chimney is designed to last a lifetime. Ideally, it will last as long as your house stands. However, this is only possible if it is properly constructed, maintained, and used.
Your Chimney System
Your chimney has one job: to vent your fire. A fire, no matter what type of fuel it burns, will release byproducts as it burns. These need to be vented out of the home. This protects the house from smoke saturation, added moisture, and health risks. In order for all of the many parts of the chimney system to work correctly, there are factors that need to be in place.
Proper Construction
Your chimney should have been constructed by a CSIA certified chimney sweep. A general contractor doesn’t have the training or knowledge of chimney science to design and build a chimney. Especially one that will vent properly, stand as long as it should, and withstand high heat.
- Design and Function
In order for your chimney to vent properly, it should be built specifically for the size of the fireplace. A chimney that is too tall or wide will not vent properly because the air will cool before it escapes through the opening, leaving the soot, creosote, and unburned wood particles on the flue walls. - Chimney Liner
Your flue liner should be properly fitted for your fireplace or fire appliance. In many older chimneys, clay tile liners were installed, and are now damaged or not appropriate for the fuel type that is used in the fireplace. The best liner available is a stainless steel one, appropriate for all fuel types, affordable, and long-lasting. Another option, and one available at Chief Chimney Services, is a relining with HeatShield® Cerfractory® Flue Sealant, which repairs and relines the flue from top to bottom at a low cost, transforming an old clay tile liner into a durable, long-lasting one, and safe for all fuel types.
Properly Maintained
Even a well-constructed chimney system can become deteriorated prematurely, when it isn’t properly maintained. The ideal chimney system is swept and inspected regularly. This is to identify any weaknesses or hazards. In addition, to maintain the highest level of safety and efficiency. When the chimney is inspected, all parts are assessed, and should be replaced if damaged.
- Chimney Cap
Prevents damage caused from water and animals. - Chimney Crown
Protects against water from the flue liner to the outer edge of the chimney opening. - Flashing
Protects the intersection of the chimney and roof, the weakest part of the chimney system, and most susceptible to water penetration. - Waterproofing
An industrial sealant that prevents water from penetrating the masonry, while still allowing vapors to escape.
Proper Use
Your chimney system is designed for one fuel. Also, it should only be used appropriately. Wood-burning systems should burn only properly seasoned wood. Gas systems should only burn natural gas, and should be checked and connected by your gas company. Proper fire safety protocol should be remembered. Plus, municipal codes and manufacturers instructions should be followed at every turn.
The chimney is a large system with many parts. Having said that, when built properly, maintained properly, and used properly – it can be the perfect addition to your dream home!
