10.2 Flame Supervision & 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:
Light the appliance. Set at the “HIGH” position and leave for one minute.
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. An
electromagnetic valve shutting off the gas supply through the tap causes this sound.
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.

ENSURE THAT YOU HAVE COMPLETED THE INFORMATION IN THE
WARRANTY AND SERVICE SECTION OF THE OWNER GUIDE (See last pages of
the OWNER guide).
2.
Visually inspect the appliance. Clean off any marks incurred during installation.
3.
Hand this guide to the customer.

enough ventilation. If this device does operate or if the fire is turned off accidentally or
intentionally, always wait three minutes before attempting to relight.
7.
Advise the customer that the fire front and ceramic fuel effect pieces can be
cleaned as described in the owner guide and that the ceramic fuel effect pieces must
be replace as described in the installer and owner guide for the ceramic fuel effect.
