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.

WARNING
:
CHECK YOUR CHIMNEY.
The chimney should be no less than
8 inches inside diameter or equal. The
chimney is a very important part of your
heating system. It must be the right size, properly
constructed and in good condition. No furnace can
function properly with a bad chimney. The chimney
must supply a draft of at least -.03 Water Column.
If possible, use a 15 foot or higher chimney. Add
an additional foot to chimney for each 1000 feet of
elevation above sea level.
