Regulator Flow Limiting Device

What is the Flow Limiting Device?

The flow limiting device is a safety feature built into the Propane regulator that detects a change in pressure, limiting the amount of propane that is delivered to a BBQ’s valve assembly, causing unstable performance.

What causes activation of the Regulator’s Flow Limiting Device?

  1. Improper lighting procedure
  2. Opening propane tank too quickly
  3. A leak in the system
  4. A positive connection has not been made between the propane tank and the valve assembly/

When should the Regulator Flow Limiting Device be reset?

  1. Burner will not light with igniter or match
  2. Burner does not get hot enough
  3. Low or incomplete burner flame pattern
  4. When a leak test is performed and no leak is found
  5. When a positive connection has not been made between the Propane tank and manifold assembly.

How do you reset the Regulator Flow Limiting Device?

  1. Open the BBQ Lid
  2. Turn ALL main control knobs to the “OFF”/CLOSED position
  3. Turn the Propane tank valve to the “OFF”/CLOSED position
  4. Disconnect the Regulator hose from the Propane tank
  5. Turn ALL main control knobs to the “ON”/OPEN position
  6. Let stand for 1-2 minutes, allowing all excess gas in valves and manifold to dissipate
  7. Turn ALL control knob back to the “OFF”/CLOSED position
  8. Reconnect the regulator hose to the Propane tank- hand tighten only.
  9. Check all hose connections to ensure that a positive seal has been made
  10. Slowly turn “ON”/OPEN the propane gas supply
  11. Wait approximately 5 seconds for the regulator pressure to stabilize
  12. Turn “ON”/OPEN the selected burner control knob to “HI”
  13. Press the INSTASTART™ ignition button or match light selected burner.

Safety Devices in Regulator

  1. Flow Limiting Device: The Flow Limiting Device alerts us to a change in gas pressure due to a leak, improper lighting procedure, system blockages, negative connections between manifold and gas source, and opening gas source too quickly.
  2. Thermal Sensor: The Thermal Sensor is built into the interior of the regulator hose. It will automatically shut off the flow of gas if the hose reaches temperatures between 115-150 degrees C (240-300 degrees F). If this temperature is reached the hose and regulator will, melt away from the tank to avoid serious damage.
