Remove the bolts holding the air duct to the burner plate and the fan.

Lift the air duct straight up. Be mindful not to lose the gasket that seals the transition to the
burner plate.

Inspect and Cl
ean the Burner
•
The burner should be clean and free of dust.
•
This can be accomplished using compressed air. Blow compressed air through the mesh
from the outside in, then empty any contaminates inside the burner can.
•
Inspect the burner signs of local overheating or soot. If soot is present, either the pilot or
the main burner has incomplete combustion. The combustion controls should be
checked, while local overheating will result in discoloured mesh or possible detachment
or sagging. The condition of the insulting heat barrier should also be checked.
