appliance or a connecting room, check that spillage does not occur with the fan
operating and all doors and other openings between the fan and the appliance open.

15.3 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;
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 Baxi
Fires Division authorised parts.
