8 Chimney Systems

A. Venting Systems

Chimney Connector:

It is also known as flue pipe or liner. It must be 6 inches (152mm) minimum diameter stainless steel liner meeting minimum standards of UL1777.

Chimney:

The chimney can be new or existing, masonry or prefabricated and must meet the following minimum requirements as specified below.

WARNING! Risk of Fire!

Follow venting manufacturer’s clearances and instructions when installing venting system.

B. Inspections

Existing chimneys should be inspected and cleaned by a qualified professional prior to installation. The chimney must not have cracks, loose mortar or other signs of dete- rioration and blockage. Hearth & Home recommends a NFI or CSIA certified professional or a technician, under the direction of a certified professional, conduct a Level II inspection per NFPA 211.

WARNING

Fire Risk

Inspection of Chimney:

•Chimney must be in good condition.

•Meets minimum standard of NFPA 211

•Factory-built chimney must be 6 inch (152mm) UL103 HT.

C.Larger Chimneys

Hearth & Home recommends that chimneys with larger diameters than 6 inches (152mm) be fully relined. An over- sized flue can affect draft and impair performance and will allow increased build-up of creosote which is why a full reline is stongly recommended.

NOTICE: Check with your local building authorities and/or consult the National Fire Protection Association (NFPA 211).

D. Masonry Chimney

•Must meet minimum standards of NFPA 211.

•Must have at least 5/8 inch (16mm) fireclay lining joined with refractory cement.

NOTE: Installations into a clay flue without a stainless steel liner may reduce draw which affects performance, will cause the glass to darken and produce excessive creosote and create start-up issues.

•The masonry wall of the chimney, if brick or modular block, must be a minimum of 4 inches (102mm) nominal thickness.

•A chimney of rubble stone must be at least 12 inches (305mm) thick.

•Cross-sectional area shall conform to NFPA 211-2006 Section 12.4.5.1.

•Should be lined with a 6 inch (152mm) stainless steel flue liner to improve performance and reduce creosote build-up and difficulty starting a fire.

•An equivalent liner must be a listed chimney liner system or other approved material.

•No dilution air is allowed to enter the chimney.

1.Secure the fireplace damper in the open position. If this cannot be accomplished, it will be necessary to remove the damper

2.Seal damper area of chimney around chimney connector with a high temperature sealant or seal insert against the face of the fireplace.

3.Both methods must be removable and replaceable for cleaning and re-installation.

•When possible, install an airtight clean-out door to the rear of the smoke shelf.

NOTE: Masonry chimneys are significantly less than ideal for venting solid fuel appliances. A masonry chimney is not subject to any temperature limit test, therefore a full reline is strongly recommended.
