With the burner assembly removed, shine a
fl
ashlight on the burner ribbons. Look for
carbon buildup, scale, dust, lint, and/or anything that might restrict
fl
ow through the
spaces between the burner ribbons. Holding the burner assembly so that any foreign
material will fall away from the burner, use a stiff bristle brush to loosen and remove
any foreign material(s). If the burner is excessively dirty, remove one of the burner end
caps. Remove the four screws that hold the end cap to the burner housing. Lightly tap
the end cap to remove it.
Clean all foreign material from the burner and venturi. After the burner is thoroughly
clean, replace the end cap making certain that it is tight against the burner housing.
NOTE:
If any of the burner components are damaged or deteriorated, replace the burn-
er assembly.
