Inspect and Clean the Burner

NOTE: If any of the burner components are damaged or deteriorated, replace the burner assembly.

Inspect the Lower Portion of the Heat Exchanger (with burner assembly removed)

Re-Install the Burner

With the burner assembly removed, shine a flashlight on the burner ribbons. Look for carbon buildup, scale, dust, lint, and/or anything that might restrict flow 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.

At the burner flame entrance of each tube, shine a bright light into each heat ex- changer section. With the light shining into the heat exchanger, observe the outside for visible light. Repeat this procedure with each heat exchanger section. If any light is observed, replace the heat exchanger.

Instructions to Re-Install the Burner (Refer to FIGURE 23.)

1.Attach the Burner Assembly - Holding the venturi tube, slide the entire burner assembly into position. Align the supports on the bottom with the slots in the burner shield; sliding the supports into the slots. On the top, re-attach each burner body support to the burner shield.
