Foster Gas Oven KS 90 - Manual (Page 11)

ADJUSTING THE BURNER AIR
Due to the characteristics of the different types of gas used, the flame
may have too little or too much air. In this case adjustment must be
performed as follows:
• Loosen the screw C on the burner (to remove the burner follow the
instructions on the previous page);
• turn the ring nut D to position N for methane or natural gas and to
position G for liquid gas so that the moving reference mark on the ring
nut coincides with the fixed reference mark on the burner, thus obtaining
a regular
flame.
Examples:
a) Flame with too much air, small and thin: turn the ring nut D to reduce
the distance X (anticlockwise).
b) Flame with too litle air, irregular with yellow tips: turn the ring nut D
to increase the distance X (clockwise).
c) Normal flame: blue color.
