(AA) Checking the Pilot Flame Unit

(AA) Checking the Pilot Flame Unit (AA-7800F,7000F, AA-7800F/AAC,7000F/AAC)
Category : 

Answer

With extended use of the instrument, soot may accumulate on the electrode in the pilot flame unit. When soot builds up in this area, it may obstruct the pilot flame, making it difficult to ignite the burner. In the worst case, the pilot flame may remain lit inside the instrument, causing a fire hazard.
1. Verify that the instrument is turned off.
2. Remove the chimney.
3. Peer into the pilot flame unit and examine the electrode.
  • AA-7800 series
    
  • AA-7000 series
     
4. If soot has accumulated on the electrode, scrape it off with a slender, rigid object, such as the tip of a flathead screwdriver. Not much force is needed to remove the soot.
    
5. Reattach the chimney.
