2. Light the appliance and turn the control knob to the 'HIGH' position.

match or a naked flame.
If the smoke is not drawn into the appliance leave the appliance alight at the
maximum setting for a further ten minutes and then repeat the test. If the flue
restrictor is fitted (See page 6 - point 4) then remove the restrictor and repeat the
above test. If the smoke is still not drawn into the appliance then disconnect the
appliance and seek expert advice.
5. If the above test is satisfactory open all internal connecting doors, hatches, etc. in
the room. Keep all doors and windows that open to the outside of the building closed.
Recheck for spillage as above. If an extractor fan is installed in the same room as the
appliance or a connecting room, check that spillage does not occur with the fan
operating and all doors and other openings between the fan and the appliance open.
If the smoke is drawn into the appliance, continue with the installation. If the test is
not satisfactory disconnect the appliance and advise the customer of the cause
of failure.
