remove the restrictor, reseal the appliance and
retest. If smoke is still not drawn into the
appliance disconnect the appliance and seek
expert advice.
5. 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. Check 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.
15.3 Flame supervision and spillage monitoring system.
This pilot unit includes 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 poor ventilation.
Check that the system operates properly as follows;
1. Light the appliance. Set the slide control to the maximum burning position and leave
for one minute.
2. Set the control to the low burning position. Isolate the gas supply at the inlet 'T'
connector. The pilot and main burner will go out. 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.
3. Open the isolating valve on the inlet 'T' connector. Screw on the end cap and test for
leaks.
4. Set the slider to the "Off' ("O") position.
