the appliance is installed with the flue restrictor (See
section 8.4), remove the restrictor, reseal the
appliance and retest. If smoke is still not drawn into
the appliance,
disconnect the appliance and seek
expert advice.
6.
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.
15.2 Flame supervision and spillage monitoring system.
The pilot unit incorporates a system that will automatically shut off the gas supply if the
pilot flame goes out or if there is insufficient oxygen due to spillage or lack of
ventilation.
Check that the system operates properly as follows;
!
Light the appliance. Set at the “HIGH” position and leave for one minute.
!
Turn back to “OFF” to extinguish the pilot.
Note the time when the pilot goes out.
Listen for a snap sound at the gas tap.
Note the time when the sound is heard.
This
sound is caused by an electromagnetic valve shutting off the gas supply through the tap.
The valve is located in the body of the tap. The valve should operate
within 60 seconds
of the pilot going out.
If the valve does not operate within this time limit do not allow
the appliance to be used until the fault has been corrected.
This monitoring system must not be adjusted, bypassed or put out of operation.
This monitoring system, or any of its parts, must only be exchanged using Baxi
Fires Division authorised parts.
