Flame Supervision & Spillage Monitoring System; Final Review - Baxi 939 Installation And Owner's Manual

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.
