  If the burner flames on your Cosmo Ranges are uneven, yellow, and/or noisy, it could be due to several reasons. First, try cleaning the burner port openings using a stiff, nylon toothbrush or a straightened paper clip. Also, ensure that the burner caps are correctly positioned, aligning the pins with the slots. If you are using propane gas, have a qualified technician convert the range to LP gas.

Why is the burner flame too high on my Cosmo COS-DFR304 Ranges?

  Christina RodriguezAug 25, 2025
  If the burner flame on your Cosmo Ranges is too high or too low, it could be due to an incorrect cooktop gas supply. Make sure the range is set for the correct gas type, as it is factory set for natural gas. If connected to LP gas, the burners should be converted by a qualified technician using the orifice/injector kit supplied, and the pressure regulator should also be converted to the LP gas setting. Another cause could be incorrect gas pressure, so ensure the pressure regulator is installed correctly and the gas line pressure is correct.

Why is there excessive heat around cookware on my Cosmo COS-DFR304 Ranges cooktop?

  If you are experiencing excessive heat around cookware on your Cosmo Ranges cooktop, it's likely because 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, and ensure it doesn't extend more than 1 inch outside the cooking area. Adjust the flame so that it does not come up around the cookware.
