Middleby Marshall PS360 Finger Configuration and PS570 Adjustments Guide

IX. PS570/570S FLAME GATE

All PS570/570S ovens produced for Pizza Hut USA through 8/00 were equipped with an adjustable flame gate at the end of the burner tube. The purpose of the flame gate was to direct heat towards the entrance end of the oven to bet- ter suit the customer’s cooking needs.

PS570S ovens produced 9/00 or later, as well as all PS570G ovens, are not equipped with the flame gate. The introduc- tion of the modulating gas system to these ovens, as well as improvements to the customer’s air finger configuration and baking specs, make the flame gate unneccessary on these ovens.

B.Flame Gate Orientation

To check the position of the flame gate, view it through the oven’s window. See Figure 53. The gate must point towards the EXIT end of the oven. Note that this directs the flame from the burner tube towards the EN- TRANCE end of the oven, as described above.

All ovens were originally shipped from Middleby Marshall with the gate pointing to the right. This is because all ovens were shipped with left-to-right conveyors. If the conveyor direction of one of these ovens is reversed in the field, the flame gate should be repostioned as fol- lows:

•Loosen (do not remove) the two 7/16” hex bolts on the clamps that hold the adjustment rod in place.

•Insert a #2 Phillips-head screwdriver into the hole in the rod as shown in Figure 53. Swing the handle of the screwdriver to rotate the rod and move the flame gate. You should position the gate as far as possible towards the EXIT end of the conveyor as shown.

•Remove the screwdriver. Tighten the two screws to hold the clamps in place.
