cabinet interior (pan slides) if not already
installed.
3. Plug power cord into proper wall receptacle.
4. Fill water pan with three (3) gallons of HOT
water (see CAUTION

ovens (maximum temperature is 350°F/177°C) as
low-heat appliances not requiring vent hoods.
4. Installation must conform with local codes. The
authority having jurisdiction of enforcement of the
codes will have the responsibility for making
interpretations of the rules.
