NOTE:
Do not use liquids or brushes when cleaning the burner.
11. Vacuum any visible debris inside the burner. Compressed air may also be
used, in moderation, to clean the pores of the woven material. Use the
following guidelines:
ƒ Dislodge any particulate matter from the burner surface matrix, keeping
the air nozzle about 2" from the burner's surface and blowing straight
down the surface. Gently move the nozzle back and forth length-wise
above the surface. Avoid blowing air tangentially across the surface as this
may cause damage to burner surface. Allow particulate matter to fall from
the burner through the air/gas inlet. A vacuum may be used at the air/gas
inlet to assist in removing particulate matter.
