14.2 Flame supervision and spillage monitoring system.
The pilot unit incorporates 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 lack of
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.
15. FINAL REVIEW
1.
Visually inspect the appliance. Clean off any marks incurred during installation.
Metal Parts
!
Clean the metal parts with a slightly damp lint free non-abrasive cloth and then dry.
!
Do not use abrasive cleaners as these will scratch the fire surface.
!
Chic, Envy and Westminster fascia -
Clean the metal parts with a slightly damp
cloth and then dry. If this does not work apply a very small amount of ‘baby oil’ to a
lint free non-abrasive cloth and wipe over the surface. Use a clean cloth to wipe off the
oil.
2.
Advise the customer how to operate the fire.
3.
Explain to the customer that the appliance has a flame failure and spillage monitoring
system. Point out the explanation of this system shown in the owner guide.
Advise that if the fire goes out for any reason, wait at least three minutes before
relighting. Stress that if the monitoring system repeatedly shuts off the fire, the
appliance should be switched off and a specialist should be consulted. Point out that the
lighting instruction details are on a metal plate attached at the bottom of the appliance.
4.
Advise that the fire may give off a slight odour while new. This is quite normal and
it will disappear after a short period of use.
5.
Advise that any cleaning must only be carried out when the fire is off and cold.
