  Uneven, yellow, or noisy flames on your Cosmo Cooktop burner can be due to several reasons: * Clogged burner ports: Clean the burner port openings using a stiff, nylon toothbrush or a straightened paper clip. * Improperly positioned burner caps: Ensure burner caps are placed so that the alignment pins are correctly aligned with the slots. * Using propane gas: Have the cooktop converted to LP gas by a qualified technician.

  If a burner on your Cosmo Cooktop won't operate, consider these potential causes: 1. If it's the first time using the cooktop, there may be air in the gas line. Turn on any one of the surface burner knobs to release the air. 2. The control knob may not be set correctly. Push in the knob before turning it to a setting. 3. The burner port may be clogged. Clean the burner port opening using a stiff, nylon toothbrush or a straightened paper clip.

  Angela PetersonAug 15, 2025
  If the burner flame on your Cosmo Cooktop is too high or too low: * Ensure the cooktop is set for the correct gas type. The cooktop is factory set for natural gas. If connecting to LP gas, the burners should be converted to LP gas with the orifice kit supplied and the pressure regulator converted to the LP gas setting by a qualified technician. * Make sure the pressure regulator is installed correctly and the gas line pressure is correct. See Installation Instructions.

Why is there excessive heat around cookware on my Cosmo COS-DIC304?
- T

  Excessive heat around cookware on your Cosmo Cooktop usually means that the cookware is not the proper size for the burner. Use cookware with a bottom surface approximately the same size as the cooking area and burner. Cookware should not extend more than 1" (2.5 cm) outside the cooking area. Adjust the flame so that it does not come up around the cookware.
