13.3 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 topmost (Off) position.
