PRE-INSTALLATION CHECK
Before installing the new cooker, check that the
chimney is clean and clear of obstructions. Cracked
brickwork and leaking joints must be made good.
Where flue piping passes through a closure plate
with a sliding door, ensure that the pipe continues up
and is ultimately connected to the flue liner and well
sealed with fire cement.
Do not connect to a flue serving another appliance.
Always ensure that the connection is to a chimney of
SEALING
