Surface burners applied do not require ad-
justment of primary air. A correct ame has
distinct internal cones of blue and green co-
lour. A short, humming ame or long, yellow
and smoking one, without clearly outlined
cones, shows improper quality of gas in the
household piping or a damaged or soiled bur-
ner. In order to check a ame, heat a burner
for around 10 minutes with a full ame, and
next turn the valve knob to the economical
ame position. The ame should not go out
or jump onto the nozzles.
