1.As the air fingers are removed use a felt pen to mark all parts of the fingers. This includes the finger manifold, inner plate and the outer plate (see Figure 1-9). If a blank or choke plate is used, mark that plate also, Fingers are marked in the order shown; as viewed from the front of the oven. (The marks for an upper oven should be

preceded with a “U”, example UB1, UT2, etc.)

3. Remove air fingers.

NOTE: Some oven users require a custom finger arrangement where the quantity of air fingers may vary.

You can remove the top and bottom fingers and blank plates from each or either end. It is highly recommended that each finger be marked before removing so it is placed in exactly the same position when reassembled (refer to step 1).

Remove the air fingers, pull the finger at the back side- pull straight out.

4.With air fingers out, place them in an upright position to remove the outer plate.

5.Gently step on the lip of the finger and pull the outer plate off.
