The oven is designed to give, well regulated, uniform heat throughout the oven.
The oven should be thoroughly preheated before being used. It is advantageous from an operating cost
stand point to operate with the switches and/or thermostats set at the lowest position that will satisfactorily
perform the cooking being done.
INITIAL PREHEAT
Before the initial use the oven must be thoroughly allowed to dry itself out. This is done by setting the top
and bottom oven switches to the “low” position, and setting the thermostat to 350 degrees. Allow the oven
to saturate until all vapor and condensation has been eliminated. For best operating results allow the oven
to thoroughly dry out. Allow 8 to 12 hours for this process.
OPERATION
The oven must be thoroughly, preheated before satisfactory baking can be done. The oven will not bake
uniformly if not sufficiently preheated.
To compensate for temperature drop when loading the oven, set the thermostat up 50 degrees over the
desired temperature. Reset thermostat after the oven is loaded.
The oven may, of course, be preheated with the 3 heat switches set at a lower position than "High", but the
time required will be proportionally longer. After preheating, set the two 3 heat switches for proper ratio of
"top" and "bottom" heat to suit the product to be baked or roasted.
The "Roasting and Baking" oven is equipped with a removable rack. For baking pies, bread, or for roasting
operations, the rack may be placed directly on the metal deck and the pans placed on the rack. For baking
cakes or pastries the rack should be located in the lower position provided by the rack supports at the sides
of the range and the pans placed on the rack in this lower position.
