INTRODUCTION
Congratulations on your purchase of a new Lucks Rack Oven. This American-made Rack
Oven bakes quickly and evenly, always with excellent results. Its scientifically designed
air-flow system eliminates the need for special controls, even when roasting and baking
delicate products.
Its electronic temperature control and efficient heating system gives faster recovery with
more consistent product quality. While baking, the self-contained steam system produces a
fine eggshell crust with excellent “shine” and good even spring. When roasting, the rack
oven’s “Cook and Hold” programming, along with intermittent steam functions allows you
to slow roast and then hold, providing significantly increased yields.
