SEALING

This cooker and flue system operate under a
positive pressure, it is essential that all flue joints are
tightly sealed against flue gas leakage and tested
accordingly (see Fig. 11 & 12).
There is a flue pipe collar available which surrounds
the flue pipe where it meets the wall, giving a tidier
finish to a tiled background (see fig. 9). The flue
pipe collar is available as an optional extra, to order.

FLUE HEIGHT

The flue must be high enough 4.5 mts. (15ft),
minimum measured vertically from the appliance
outlet to the top of the flue terminal, to allow the flue
gases to vent into the clear air, away from the
turbulence that may be caused by roof structures,
other chimney stacks, etc.
Refer to Flue Assembly Instructions sheets.
Fig.13)
The terminal position should be in accordance with
B.S. 5440 Part 1 & the current Building Regulations.
If it is necessary to offset the chimney the
recommended angle is 60° to the horizontal and the
statutory minimum is 45° (see fig. 14).
Note: Never connect to a chimney or flue system
serving another appliance.

CONNECTIONS
A cast iron 90° bend with cleaning door is supplied
with the cooker, along with a cast iron spigot for
connection to a vertical flue pipe. A vertical cast
iron outlet pipe with cleaning door is available to
order. A flexible flue adaptor is supplied, this is to
connect the cooker bend or straight pipe to the
chimney liner.
Note: Maximum horizontal length should not be
more than 300mm (12") where the appliance spigot
or flue pipe protrudes into the chimney, care should
be taken to ensure that it does not block the
chimney.
