Low Flame on Flat Top Grill

What's in This Article?

This article covers common causes of a low flame on a Traeger flat top grill and how to fix it.

Symptoms

Burners light but the flames are not at normal levels. The cooktop will not get very hot, even on high.

Common Causes of Low Flames 

  • Regulator hose is kinked, blocking gas flow
  • Regulator hose isn't fully connected to the tank
  • Tank valve is not fully open
  • Low fuel level in propane tank
  • Blockage in burner
  • Bad regulator hose

 

What to Do if Your Flatrock Flame Is Low

If your burners are putting out low or uneven flames, here are some of the possible causes and their resolutions:

  1. Empty or low propane tank - Replace or refill propane tank to resolve.
  2. Propane tank valve not opened sufficiently- The tank valve should be opened by turning it counter-clockwise until it stops and then turning it back one half turn.
  3. Regulator hose not fully attached to the tank valve - Correct by tightening the regulator fitting as much as possible by hand. Avoid using tools in case of damage.
  4. Bend or kink in regulator hose - This will restrict flow, and may cause a low flame or even no flame. Replace the regulator hose.
  5. Obstructions in the burner tubes- There may be environmental obstructions in the burner tubes when the grill has not been used for long periods of time. Wrap the tubes in aluminum foil to avoid insects entering the burner holes. See how to clean and maintain your burner tubes here.

Regulator Hose Safety Trip

Regulator hoses are equipped with a safety feature that is designed to limit the flow of propane if the flow through the regulator is higher than normal.

See also, Gas Leak, for steps on how to check for a gas leak.

While this is to protect from issues such as a hose or manifold leaks, it can also trip from seemingly normal use. When the regulator safety feature trips, some gas may still flow which will lead to low or uneven flames. Gas flow may also be stopped, making it impossible to light burners. 

Contact Customer Support if you suspect your regulator hose has tripped.
