Oven

Operation

! IMPORTANT

DO NOT USE aluminium foil or trays directly on the cast iron sole plate(s).
NEVER block or cover the openings on each side of the sole plate(s).

The oven is fitted with top and bottom elements. The thermostat maintains the overall oven
temperature. The top element is further controlled by the oven top heat control. Convection ovens
(RN8110GEC) are fitted with a circulation fan.

NOTE: The Thermostat on the static oven provides overall control of the temperature within the

oven by controlling both elements, where as the Oven Top Heat Control provides a means
of balancing the distribution of heat between the top and bottom of the oven.

Place oven racks in desired position.

Preheat:

Preheat the oven by selecting the desired temperature, and turning the oven top heat control (Refer
to Fig 5 on the previous page) to a maximum of 2. When the desired temperature is reached, the
amber neon will go out.

! IMPORTANT

DO NOT USE aluminium foil or trays directly on the cast iron sole plate(s).
NEVER block or cover the openings on each side of the sole plate(s).

Cooking:

When the desired temperature has been reached, load the oven with product and set the oven top
heat control to the desired setting.

NOTE: When the oven top heat control is set to a high setting, proportionally more heat is

produced at the top of the oven. (This can be used for browning, etc, during the cooking
operation). With the oven top heat control set on a low setting, less heat is produced from
the top oven elements. (This mode is used for general baking purposes to prevent cakes,
etc, from getting too brown and crisp on the top, but allow the cake to cook through).

To obtain more top heat during cooking, turn the oven top heat control to a higher position. (The
higher the setting, the more top heat).

Turning ‘OFF’ the Oven:

a. Turn the oven top heat control to the ‘O’ off position. The top heating will be turned ‘OFF’ and

the upper heating indicator lamp (Amber) will extinguish.

b. Turn the thermostat control knob to the ‘O’ off position and the lower heating indicator lamp

(Amber) will extinguish. The oven is now turned ‘OFF’.
