These  consumable  parts  should  be  replaced  as  soon  as  they  show  signs  of  wear.    Running  your  burner  with 
worn or broken parts may result in reduced output, an increase in fuel consumption, and even can damage the 
firebox or other vital parts of the burner.  We highly recommend a frequent visual check of these consumables 
and other parts of the burner.  Refer to the schematic below of various Rakaia parts.
