If the flame is blue, this means that the combustion is effective, as the gas and oxygen mix well.
If the flame is red or orange, this indicates that the combustion is incomplete, which may lead to increased gas consumption, blackening of the pan, delayed heating, and accumulation of dangerous gases.
Therefore, it is necessary to open doors and windows and ensure good ventilation during cooking.
The reasons for incomplete combustion are:
- Blockage of fuel passages and ventilation systems.
- Improper installation of the stove.
- Failure to clean the gas stove regularly to remove rust, soot, scales, and dust.
- Insufficient pressure in the cylinder.
