5. Exterior cleaning
Wash the oven cabinet on the outside with soapy water and dry with a soft and damp cloth.
After drying, apply HOUNÖ STEEL OIL (follow directions on the packaging).
Clean the oven door glass with ordinary window cleaner.
Note! The exterior of the oven must never be flushed with a water hose or high-pressure cleaner
as this may damage the electronic components.
6. Cleaning of exhaust valve
The exhaust valve should be checked once a week.
Remove the valve, clean thoroughly with a brush and detergent, rinse with water, dry, and fit
again. It is very important to avoid the forming of a layer of fat on the valve, as the fat might
affect the valve’s ability to function.
