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.
13.2.5If 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 advise the customer of the
cause of failure.
13.2.6If any other non-sealed gas appliances are installed in the room or
connecting rooms, check to ensure that there is no spillage from these
appliances when Model 517 is operating with its fan on. Check these other
appliances by the procedure supplied by the manufacturer.
13.3 Flame Supervision & Spillage Monitoring System
This 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;
13.3.1 Turn on the fan. Light the appliance and turn the control knob to
"HIGH". Leave for one minute.
13.3.2 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 Valor
authorised parts.
