USE
Notes:
Use of a gas cooking appliance produces heat and moisture in the room in which it
is installed. The room must therefore be well ventilated by keeping the natural air
vents clear (fig. 3) and by activating the mechanical aeration device (suction hood
or electric fan fig. 4 and fig. 5).
Intensive and lengthy use of the appliance may require additional ventilation. This
can be achieved by opening a window or by increasing the power of the mechanical
exhausting system if installed.
Abnormal Operation:
Any of the following are considered to be abnormal operation and may require
servicing:
- Yellow tipping of the hob burner flame.
- Sooting up of cooking utensils.
- Burners not igniting properly.
- Burners failing to remain alight.
- Burners extinguished by cupboard doors.
- Gas valves which are difficult to turn.
