Safety first: Turn off the burner and allow it to cool. Close the gas supply if removing injectors.

Clean burner thoroughly: Remove burner cap and head. Clean all surfaces and ports. Ensure no cleaning product residue remains.
Check air inlets: Inspect the area around the injector and venturi for lint, grease, or debris blocking air flow. Clean with a soft brush.
Verify gas type: Confirm that the appliance is configured for your gas type (natural gas or LPG). Check the rating plate and any conversion labels.
Inspect injectors: If the appliance was converted, ensure the correct Glem Gas injectors are installed for each burner size and gas type. Replace incorrect jets.
Adjust air shutter (if fitted): Some burners have adjustable air shutters near the injector. Adjust slightly to achieve a stable blue flame without lifting or yellow tips.
Call a gas technician: If you are unsure about injector sizing or gas type, have a licensed gas fitter inspect and adjust the appliance.
