3. Once the fire sensor feature has shut the unit down, the
programmed cooking cycle may be resumed by pressing
the "START" pad or the unit may be reset by pressing the
"CLEAR" pad.
IMPORTANT:
During sensor cooking operation, the fire sensing op-
eration sequence will not begin until the AH sensor has
detected vapors and initiated a sensor cooking cycle.
This is because the operation of the convection fan
would interfere with the AH sensor's vapor detection.

VENTILATION METHODS HOT AIR EXHAUST
1. VERTICAL VENTING
For this venting method, hot air rising from the
conventional range below is drawn in by the hood fan
motor through the grease filters at the right and left sides
of the base cover, up through the right and left side intake
ducts, then discharged vertically at rear center top of the
oven, into the customer's vent system.
2. HORIZONTAL VENTING
The air handing is same as VERTICAL VENTING except
that the final air discharge is directed horizontally out
from the top rear of the oven into the customer's vent
system.
3. RE-CIRCULATION (INSIDE VENTING)
The air handing is same as VERTICAL VENTING except
that the final air discharge is directed horizontally through
the upper front of the oven into the kitchen. IN this case,
the accessory charcoal filter lit RK-220 must be provided
to filter the air before it leaves the oven.
