CHIMNEY CONNECTOR (STOVE PIPE)
The chimney connector and chimney must be no smaller than the stove
outlet 127mm for the Bewdley 3&5, 152mm for the Bewdley 8. If this is
not the case, we recommend you contact the dealer in order to ensure
there will be no problem with the draught.
The stove pipe must be made of aluminized or cold roll steel with a
minimum thickness of 0.53mm. It is strictly forbidden to use galvanized
steel. Stove pipe made from vitreous enamel or stainless steel is also
acceptable.
The stove pipe should be assembled in such a way that the male section
(crimped end) of the pipe faces down. Install as per the manufactories
installation guidelines.
The pipe must be short and straight. All sections installed horizontally
must slope at least 21mm per metre, with the upper end of the section
toward the chimney. Any installation with a horizontal run of chimney
pipe must conform to national and local regulations.

To ensure a good draught, the total length of the coupling pipe should
never exceed 2.4m to 3.03m. Except for cases of vertical installation,
cathedral-roof style where the smoke exhaust system can be much
longer and connected without problem to the chimney at the ceiling of
the room.
Installation of a "barometric draught stabilizer" (fireplace register) on a
smoke exhaust system is prohibited.
Furthermore, installation of a draught damper is not recommended.
Indeed, with a controlled combustion stove the draught is regulated
upon intake of the combustion air in the stove and not at the exhaust.
