DESOOTING PROCEDURE

CAUTION: SOOT IS COMBUSTIBLE. EXERCISE EXTREME CARE. NEVER USE A WIRE BRUSH.

Soot can clog areas between fins and cause even- tual tube failure. Any sign of soot at the base of the burners or around the outer jacket indicates a need for cleaning.

1.Disconnect top portion of unit. (See heat ex- changer

removal procedure steps 1 through 6).

2.Remove burner tray (See burner tray removal procedure.)

3.Take a garden hose and wash heat exchanger, making sure soot is removed completely from be- tween fins. Avoid excessive water against refrac- tory.

NOTE: In extreme cases it may be necessary to re- move the heat exchanger completely for cleaning. The simplest method is steam cleaning at the local car wash. DO NOT WIRE BRUSH.

COMBUSTION CHAMBER REMOVAL

1.Remove heat exchanger (See heat exchanger removal procedure).

2.Lift up and remove front and rear refractory shield.

3.Remove refractory panels.

4.Reverse above procedure to re-install.
