INSTALLER GUIDE
8.2 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 high (H) position and leave for one
minute.
2. Set the control to the low (L) 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. Set the slider to the off (O) position.
4. Open the isolating valve on the inlet 'T' connector. Screw on the end cap and test
for leaks.
8.3 Check reference pressure.
The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 4 of this manual. No adjustment is necessary.
1. Make sure the slider button is at the off (O) position (Topmost position).
2. Remove the fascia (if necessary). To do this, remove the two knurled fascia
retaining screws located at the bottom rear sides of the fascia. Gently pull the bottom
of the fascia forward then lift the fascia up and forward to clear the rear top location.
3. Check the burner pressure by fitting a pressure gauge at the test point located on
the lower injector carrier at the right hand side of the burner. Check the pressure with
the appliance alight and set at the high (H) setting.
4. After checking, turn off the appliance. Remove the pressure gauge and replace the
test point sealing screw. Relight the appliance. Turn to the high (H) setting and test
around the sealing screw for gas soundness with a suitable leak detection fluid.
5. If all the above checks are satisfactory, continue with the installation. If not, check
the control and components as described in the servicing and parts replacement
section of this manual.
