Burner flames that burn yellow on the tip of the flame (over 1 inch) are
a sign that the burner is not receiving enough air for the combustion of
gas. If the tip of the flame is more yellow in appearance, this could
indicate that the burner's air shutter (or Venturi) needs to be adjusted,
so that it can produce more air. Please be aware of any carbon or
soot deposits that may build up on the burner as this too will affect the
burners ability to cook evenly and properly.

ALWAYS PREFORM A GAS LEAK CHECK BEFORE USING GAS
HOB!
Before operating the gas hob, always preform an analysis
or check for a gas leak. DO NOT use gas hob until the leak test
is preformed and confirmed there are no gas leak indications.
Test for leaks by using between 11-13.8 WC pressure.
- if there is a gas leak detected, replace the defective part
recommended by the manufacturer or tighten the loose joint properly.
