CLEANING PILOT AIR INLET HOLE
Clean the pilot assembly also. A yellow tip on the pilot flame
indicates dust and dirt in the pilot assembly. There is a small pilot
air inlet hole about two inches from where the pilot flame comes out
of the pilot assembly (see Figure 58). With the unit off, lightly blow
air through the air inlet hole. You may blow through a drinking straw
if compressed air is not available. You may also clean the pilot air
inlet hole by pushing a common pipe cleaner completely through the
air inlet hole once.
LOGS
• If you remove logs for cleaning, refer to Installing Logs, pages
