!
Leave the appliance on for five minutes.
!
Place the smoke match tube into the burner box below
the hood (See figure 36).
!
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 this Powerflue fire is
operating with its fan on. Check these other appliances by the procedure supplied by the
manufacturer.
12.3 Flame supervision & 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.
