CheCk 1 - proper Chimney terminAtion.
A masonry chimney used as a vent for gas red equipment
must extend at least three feet above the highest point where it
passes through the roof. It must extend at least two feet higher
than any portion of a building within a horizontal distance of
10 feet. In addition, the chimney must terminate at least 3 feet
above any forced air inlet located within 10 feet. The chimney

(C
ategory i furnaCeS only)
An exterior masonry chimney is dened as a “Masonry” chim-
ney exposed to the outdoors on one or more sides below the
roof line.” The ability to use a clay lined masonry chimney
depends on a parameter not associated with interior chimneys.
This variable is the geographic location of the installation.
Researchers have discovered that the winter design tem-
peratures have a direct impact on the suitability of this type
of venting. In most situations, the existing masonry chimneys
will require a properly sized metallic liner.
POSSIBILITY OF PROPERTY DAMAGE, PERSONAL INJURY OR DEATH
DAMAGING CONDENSATION CAN OCCUR INSIDE MASONRY CHIMNEYS
WHEN A SINGLE FAN-ASSISTED CATEGORY I APPLIANCE (80% AFUE
FURNACE) IS
VENTED WITHOUT ADEQUATE DILUTION AIR. DO NOT
CONNECT AN 80% FURNACE TO A MASONRY CHIMNEY UNLESS THE
FURNACE IS COMMON VENTED WITH A DRAFT HOOD EQUIPPED
APPLIANCE OR THE CHIMNEY IS LINED WITH A METAL LINER OR TYPE B
METAL VENT. ALL INSTALLATIONS USING MASONRY CHIMNEYS MUST BE
SIZED IN ACCORDANCE WITH THE APPROPRIATE VENTING TABLES. IF AN
80% FURNACE IS COMMON VENTED WITH A DRAFT HOOD EQUIPPED
APPLIANCE, THE POTENTIAL FOR CONDENSATION DAMAGE MAY STILL
EXIST WITH EXTREMELY COLD CONDITIONS, LONG VENT CONNECTORS,
EXTERIOR CHIMNEYS, OR ANY COMBINATION OF THESE CONDITIONS.
THE RISK OF CONDENSATION DAMAGE IS BEST AVOIDED BY USING
MASONRY CHIMNEY AS A PATHWAY FOR PROPERLY SIZED METAL LINER
OR TYPE B METAL VENT.
