14.1 Check for spillage.
1.
Close all doors and windows in the room containing the appliance.
2.
Light the appliance and turn the control knob to “HIGH”.
3.
Leave the appliance on for five minutes.
4.
Place the smoke match into the appliance
canopy (See figure 37).

The installation is satisfactory if the smoke is
drawn into the appliance. 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 smoke is still not drawn into the
appliance, inspect the sealing to the fireplace
surround. If the sealing is satisfactory but the
appliance is installed with the flue restrictor (See

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.
