Clogged nozzle restricts the flow of gas, leading to a reduced gas volume available for combustion, slowing down the rate of combustion and producing a smaller or nonexistent flame.

Clogged nozzle increases the flow of gas, leading to an excess gas volume available for combustion, increasing the rate of combustion and producing an oversized flame.

Clogged nozzle ensures even distribution of gas, resulting in efficient combustion and a consistent flame.

Clogged nozzle allows for rapid bursts of gas intermittently, causing an unpredictable and fluctuating flame.
