all doors and windows that open to the outside of

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: -
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
.
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 Valor
Fires authorised parts.
