Venting and Chimney Systems
A. Venting Systems
The venting system consists of:
• A chimney connector (also known as fl ue or stove pipe)
• A chimney
• Thimble
These get extremely hot during use. Temperatures inside
the chimney may exceed 2000°F (1100°C) in the event of a
creosote fi re.
To protect against the possibility of a house fi re:
• Chimney connector and chimney must be properly
installed and maintained.
• An approved thimble must be used when a connection is
made through a combustible wall to a chimney.
• A chimney support package must be used when a
connection is made through the ceiling to a factory built
chimney.
• An approved thimble and chimney support package are
absolutely necessary to provide safe clearances to
combustible wall and ceiling material.
B. Chimney Systems
• The chimney connector joins the stove to the chimney.
• It must be a 6 inch (152mm) minimum diameter 24 gauge
mild steel black or 26 gauge blued steel.
• Or an approved air-insulated double wall venting pipe.
Single wall connector or stove pipe
• Must be at least 24 gauge mild steel or 26 gauge blue
steel.
• Sections must be attached to the appliance and to each
other with the crimped (male) end pointing toward the
stove.
• All joints, including the connection at the fl ue collar, should
be secured with 3 sheet metal screws.
• Follow the minimum clearances to combustibles
Factory-built chimney connector (vented)
• A Listed connector (vented) must be used when installing
this unit in a mobile home.
• The Listed connectors must conform to each other to
ensure a proper fi t and seal.

Figure 34.1 Chimney Connector
A thimble is a manufactured or site-constructed device
installed in combustible walls through which the chimney
connector passes to the chimney.
• It is intended to keep the walls from igniting.
• Site constructed thimbles must meet NFPA 211
Standards.
• Factory-built must be suitable for use with selected
chimney and meet UL103 Type HT Standards.
• Follow instructions provided by the manufacturer for
manufactured thimbles for masonry chimney and factory-
built chimneys.
WARNING! Risk of Fire!
Follow chimney connector manufacturer’s instructions for proper
installation.
ONLY use connector:
• Within the room, between appliance and ceiling or wall.
Connector shall NOT pass through:
• Attic or roof space
• Closet or similar concealed space
• Floor or ceiling
Maintain minimum clearances to combustibles
NOTICE: Where passage through the wall, or partition
of combustible construction is desired in Canada, the
installation shall conform to CAN/CSA-B365.
WARNING! Risk of Fire!
Follow venting manufacturer’s clearances and instructions
when installing venting system.
• This product was designed for and tested on a 6 inch
(152mm) chimney, 14 to 16 feet (427-487cm) high, (in-
cludes appliance height) measured from the base of the
appliance.
• The further your stack height or diameter varies from this
confi guration, the possibility of performance problems
exists.
• Chimney height may need to be increased by 2
- 3% per
each 1000 feet (304.8m) above sea level.
• It is not recommended to use offsets or elbows at altitudes
above 4000 feet (1219.2m) above sea level or when there
are other factors that affect fl ue draft.
