FLAME FAILURE FUNCTIONAL CHECK 3
PILOT WILL NOT STAY LIT OR FIRE GOES OUT IN USE
If the appliance goes out in use continually, this may mean that the oxygen
depletion sensor has been activated. The appliance should not be used until the
cause has been found and rectified.
Ensure there is no debris around the pilot assembly,
(e.g. coal, soot etc.) Check for fluff in the pilot aeration hole.
See diagram 13 arrow A in replacing parts section.
