Chimney Connector Requirements
Chimney connector is required from the flue collar of the stove to the
factory-built chimney or masonry chimney. The chimney connector
must be 6” (152mm) diameter and a minimum 24 gauge black steel.
Aluminum or galvanized steel is not allowed – these materials cannot
withstand the flue temperatures and may give off toxic fumes when
heated.
The chimney connector may not pass through a ceiling, attic, roof,
closet, or any other concealed space (use listed UL 103 HT chimney –
see “Chimney Requirements for details). DO NOT USE CONNECTOR
PIPE AS CHIMNEY.
The chimney connector should be as short and direct as possible. No
more than 180
o
of elbows (two 90
o
elbows, or two 45
o
& one 90
o
elbow,
etc.) may be used for the entire system (connector and chimney). Do
not use “T” connections in installation. Horizontal runs should slope
upwards 1/4” (6mm) per foot and be a maximum 36” (914mm) long.
The chimney connector must be installed with the crimped end pointing
downwards. This prevents creosote from leaking to the exterior of the
pipe.
The chimney connector must be fastened to the stove and each
adjoining section (and chimney) and kept clean.
Each joint in the chimney connector must be hermetically sealed to
prevent smoke leakage using furnace cement, high temperature
silicone sealant or other suitable sealing medium. Smoke leakage from
the chimney pipe is a sign of improper sealing.
