10. Installing the Chimney Connector
The chimney connector is the single or double wall pipe installed between the stove flue collar
and the chimney breech. Single wall pipe components are available from most hardware and
bu ilding supply stores. These components are not usually tested to a particular standard and
certified as compliant. Therefore, a list of rules found in solid fuel installation codes apply to the
installation of a single wallpipe.
Double wall chimney connectors are tested and certified. The rules for double wall pipe a
refound in the manufacturer’s installation instructions. These rules will be very different than
those for single wall.
10.1 Installation of Single Wall Chimney Connector
The chimney connector assembly has been called ‘the weak link’ in the safety of wood heating
systems because failure to install the connector properly (which has been common in the past)
can result in house fires.
The best flue pipe assembly is one that rises straight up from the stove to the base of the
chimney with no elbows. Straight assemblies are less likely to cause problems like smoke rollout
when the door is opened for loading. They are also more stable and easier to maintain than
assemblies with elbows. Horizontal runs of flue pipe should be avoided where possible because
they reduce chimney draft.

The rules below are based on those found in the CSA B365 installation code. Please carefully
follow these installation instruction rules, or those enforced by the local code.
• Maximum overall length of horizontal pipe: 10 ft. (3 m) including elbows.
• Minimum clearance from combustible material: 18" (450 mm). The minimum clearance may be
reduced by 50 percent to 9" (225 mm) if suitable shielding is installed either on the pipe or on the
combustible surface.
