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 32).

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
section 8.2), remove the restrictor, reseal the
appliance and retest. If smoke is still not drawn into
the appliance, disconnect the appliance and seek
expert advice.

all doors and windows that open to the outside of the

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.
