Chimney codes safeguard your property and you and your family’s health and safely. They also serve as a guide for construction, installation and maintenance to ensure safe heating and correct ventilation.
Different states adopt these codes from the National Fire Protection Association (NFPA) and the International Code Council (ICC) and modify them as they see fit. Since regulators frequently change chimney code requirements, hiring an expert who can help you stay compliant is crucial. In Atlanta, chimney codes follow the International Residential Code (IRC) for one and two-family dwellings.
Chimney Caps Code Requirements
Chimney caps keep out rain, debris and pests while facilitating smoke and gas release. They also protect the structure from moisture damage and reduce the adverse impact of wind.
Georgia’s minimum state standards for one and two-family dwellings require masonry chimneys to have stone, concrete or metal caps featuring drip edges. They must be sloped and have a caulked bond break surrounding the flue liner.
Are Chimney Liners Required by Code?
Yes, chimney or flue liners are required by the NFPA. Georgia also requires the lining of all masonry chimneys with a material that matches the appliance as per the manufacturer’s instructions. Different types of liners available include metal, clay tile and cast-in-place cement, with clay tile being the most common.
According to Georgia’s minimum residential standards regarding clay flue liners, you must install them with tight mortar joints that are smooth on the inside and support them on all sides.
Other chimney liner code requirements for clay tile include:
- Maintaining an airspace during installation.
- Carrying the lining up vertically with a slope less than 30 degrees from the vertical.
- Building masonry wythes between adjacent lining when you use multiple flues.
- Keeping the liner separate from the grout, allowing it to move with thermal expansion.
Is a Chimney Liner Necessary?
Yes, a chimney liner is essential because it:
- Reduces heat transfer to supporting structures, safeguarding your home.
- Prolongs the life of the chimney’s masonry by protecting it from the corrosive byproducts of combustion.
- Enables safe venting of gas or wood-burning appliances.
- Improves draft flow when sized correctly, boosting combustion efficiency.
- Helps you meet home insurance requirements.
- Boosts your home’s value due to increased safety, efficiency and reduced maintenance needs.
