Flame stability in a flame effect system depends on a steady, adequate fuel supply that matches the air flow. When the fuel pressure is inadequate, there isn’t enough fuel reaching the burner to sustain the flame as the blower or air system drives the mixture. The result is a flame that flickers, hesitates at ignition, or cuts out and relights intermittently—the telltale signs of misignition or instability. If the fuel line or pump can’t keep up, the system can never maintain the correct fuel-to-air ratio, so the flame becomes erratic.

Other causes exist but are less likely to be the primary reason for frequent instability in normal operation. An overly stable air mixture doesn’t inherently produce instability the way insufficient fuel does, because the issue is the missing fuel, not the air’s behavior. Ignition device failure tends to prevent ignition altogether or produce sporadic sparks, not a flame that can’t stay lit once it has started. Faulty interlocks mainly cause shutoffs for safety rather than cause a flame to intermittently misbehave during steady operation.
