Place the smoke match tube into the burner box below the
!
hood (See figure 33).
The installation is satisfactory if the smoke is drawn into the
!
appliance. If the smoke is not drawn into the appliance the fan
powered extraction system is not operating correctly. Do not
allow the appliance to be used until the fault is corrected.
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 or other air circulating system 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 seek expert advice.
If any other non-sealed gas appliances are installed in connecting rooms, check to
!
ensure that there is no spillage from these appliances when the Powerflue is operating
with its fan on. Check these other appliances by the procedure supplied by the
manufacturer.
12.3 Flame supervision and spillage monitoring system.
The pilot unit incorporates a system which 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;
Turn on the fan. Light the appliance and turn the control knob to "HIGH". 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 Authorised
parts.
