The Ovens
Roasting Oven and Grill
The upper oven is indirectly heated by two elements, one concealed in the base of the oven and the
other is visible in the roof. These elements heat the lined cavity to provide cooking results consistent
with traditional heat storage ovens, but with the flexibility to turn the ovens off when not in use. The
appliance features three settings Roast, Grill & Bake
Baking/Simmering Oven
The lower oven is indirectly heated by two elements, one concealed in the base and the other visible
in the top of the oven. These elements heat the lined cavity oven to provide cooking results
comparable with traditional heat storage ovens, but with flexibility to turn the oven off when not in
use. The appliance features two settings bake and simmer.
Warming Oven
The Warming oven is indirectly heated by one element which is fitted underneath the oven.
The OVEN IS NOT A HOLDING OVEN and therefore is not designed to hold food at a given
temperature for long periods
