Cleaning and Maintenance/Pilot
Oxygen Depletion Sensor Pilot (Figure 21)
When the pilot has a large yellow tip flame, clean the Oxygen
Depletion Sensor as follows:
1. Clean the ODS pilot by loosening nut B from the pilot
tubing. When this procedure is required, grasp nut A with
an open end wrench.
2. Blow air pressure through the holes indicated by the arrows.
This will blow out foreign materials such as dust, lint and
spider webs. Tighten nut B also by grasping nut A.
Annual inspection and cleaning by your dealer or qualified
service technician is recommended to prevent malfunction
and/or sooting.
TURN OFF HEATER AND ALLOW TO COOL BEFORE
CLEANING.
Remove logs, handling carefully by holding gently at each end.
Gloves are recommended to prevent skin irritation from ceramic
fibers. If skin becomes irritated, wash gently with soap and water.
Refer to manual for correct log placement.
