2.3. Smoke vent:
The flue must be installed in line with current
Building Regulations.
Flue:
The flue must be in perfect condition and
allow a good draft (see general characteristics
for details).
The flue must not be shared with any other
appliances.
The flue must be Class I (suitable for solid
fuel).
The flue must be swept prior to installation.
The flue should be lined and insulated.
The flue must be rain-proof.
The flue must be a minimum height of 5
meters and should terminate 40 cm above the
ridge of the house or any nearby dwellings.
There should be an 8m clearance from the flue
to any other building.
The flue draft of 20 Pa is required for correct
operation-if the flue does not have this draft, it
will be necessary to incorporate a flue draft
stabiliser or fan to the flue system.
The weight of the flue must be independently
supported.
The diameter of the flue must not be less than
150mm.
The draft regulator must be visible and easily
accessible for maintenance.
A flue sweeping access is recommended
within the installation.
The flue must be in line with current Building
Regulations.
2.4 Assembly of the gas flue:
The flue outlet diameter is 150mm internal
diameter.
2.5 Connection to the chimney:
The flue spigot which connects the appliance
to the flue must be fitted in accordance to
local building regulations.
The cooker must be as near as possible
•
from the flue.
The appliance must be connected to an
•
individual gas flue, never to a gas flue
shared with other appliances.
•
The cooker must be connected to the
chimney flue using special piping to
withstand the products of combustion
(e.g. stainless steel, enamelled steel).
This piping is available from specialised
traders.
The diameter of the piping must not be
•
smaller than the diameter of the flue
socket on the appliance.
To connect the flue to the socket, insert
•
the piping about 4 cm inside the socket
and seal the joint with fire sealant or fire
cement to make it completely airtight.
•
The connections between the flue piping
and the cooker and between the flue
piping and the chimney flue must be
airtight. An optimum seal can be checked
from the hatch on the oven.
In rooms equipped with Controlled
•
Mechanical Ventilation, the ventilation
gas outlet must never be connected to the
gas flue.
The flue connector piping and the
•
optional draught regulator must be
visible, accessible and easy to clean.
It is recommended to fit a cleaning trap.
