3. Check the regulator gas pressure (4- inch water column for NG)
4. Check the burner BTU for each burner (BTU is not changing after NG Conversion)
5. Check the flame condition (See below picture)
   – Visually check the burner flames. They should be blue or slightly yellow.
   – Check and clean all burners/ venturi tubes for insects and insect nests. A clogged tube can lead to fire hazard under the outdoor cooking grill.
