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.

Light the pilot and keep the control knob pushed in
