  • Page 19: Initial Start-Up

    INITIAL START-UP INITIAL PREHEAT Prior to putting any range or oven into full time operation at normal cooking temperatures, it must be thoroughly dried out. Moisture absorption in the closed spaces, in the insulation, and even inside the heating elements can cause future trouble if not properly treated.

  • Page 20: Operation

    The convection oven roasts and bakes in shorter time and at lower temperatures with less shrinkage than conventional commercial ovens. A blower in the Lang convection oven circulates air within the chamber to heat the entire space evenly and transfer heat efficiently to the product, even with stacked loading.
