Simply put, something is obstructing gas flow.
Here are some things to check:
Possible Cause 1: No gas flow.
- Solution: Confirm the LP tank is connected and on.
- Solution: Confirm LP tank is not empty. If empty, replace and/or refill. If not empty, read the following:
- Excess flow safety device may have been activated. - Turn control knob to “OFF”, wait 30 seconds and light outdoor fire unit. If flames are still too low, reset the excessive flow safety device by turning off the control knob and LP gas tank valve. Disconnect regulator. Turn burner control knob to “HIGH”. Wait 1 minute. Turn burner control knob off . Reconnect regulator and perform a leak check at tank connection. Slowly turn LP gas tank valve on, wait 30 seconds and then light outdoor fire unit.

- Solution: Confirm your natural gas line is turned on.
Possible Cause 2: Coupling nut (connected to regulator) and regulator not fully connected.
- Solution: Turn the coupling nut about one half to three fourths a turn, until you feel a solid stop. Do not use tools, tighten by hand only.
Possible Cause 3: Obstruction of gas flow.
- Solution: Check for bent or kinked hose.
Possible Cause 4 (this is more common than you may think): Spider webs or insect nest in the Venturi.
- Solution: Clean the Venturi.
Possible Cause 5: Burner ports clogged or blocked.
- Solution: Reference “Problem: Irregular flame pattern” on the following page. Clean the burner ports as described there. Simple way: Do this by inserting a paperclip into each of the burner ports to ensure they are not clogged.
*WARNING: Make sure burner is not on and the gas supply has been properly disconnected. Allow 15 minutes for unit to cool before touching it.
