Catalytic enamel surface
The removable back panel and side panels (if fitted) are coated with
a dark brown catalytic enamel.
During fan operated cooking circulating air in the oven deposits oil
and fat splashes predominantly on the back panel of the oven.
These splashes are burnt off when the temperature of the oven
reaches over 200°C during baking or roasting.
The higher the temperature the more effective the process.
Note that deposits of spices, syrups and similar substances are not
removed by this process.
These should be removed while fresh by hand with a mild solution
of hot water and washing up liquid applied with a soft brush.
The oven and accessories should be cleaned after each use.
Otherwise further baking and roasting will cause the deposits to
bake on even harder and cleaning may become difficult and in
extreme cases impossible!
Note: Do not use abrasive cleaning agents, hard brushes,
scouring pads or cloths, steel wool, knives or other
abrasive materials and do not use oven spray on
catalytic enamel as chemicals used in oven sprys will
damage catalytic enamel rendering it ineffective.
If using oven sprays on the oven surface (cavity) the catalytic back
panel must first be removed from the oven.
