PROPER CHIMNEYS

The National Fire Protection Association (NFPA) requires that all factory built chimneys be Listed and installed in accordance with conditions of the Listing in the manufacturers instructions. NFPA also requires that your chimney extend at least three (3) feet above the highest point when it passes through the roof and at least two (2) feet higher than any portion of the building within ten (10) feet of the chimney.

Factory built chimneys must be what NFPA refers to in NFPA 211 1-5.217.4 as Type HT. HT is an abbreviation meaning high temperature.

Masonry Chimneys as referred to in NFPA 211 1-5.2.17.6, a field constructed chimney of solid masonry units, bricks, stones, listed masonry chimney units, or reinforced concrete that is lined with suitable chim- ney flue liners and built with the provisions of Chapter 4 of this standard.

As described in NFPA 54 (National Fuel Gas Code) section 7.5.5 (c) A Listed combination gas and solid fuel appliance equipped with a manual reset device to shut off gas to the main burner in the event of flue gas spillage shall be permitted to be connected to a single chimney flue. The chimney flue shall be sized to properly vent the appliance.

All gas-solid fuel and oil-solid fuel combination furnaces in this manual are Underwriters Laboratories Listed for one flue.
