Problem? Solution: TUTH's BBQ Troubleshooting Guide 

Problem: Barbecue Not Hot enough

Solutions: 

The new right hand thread QCC1 system is designed to shut down the flow of gas to a minimal amount should it detect a cut or leak in the gas hose. It can also be triggered by turning on the cylinder valve too quickly.  

• To re-set: Turn cylinder valve off. Turn all burner knobs off. Remove regulator from tank. (It is now re-set) Connect regulator to tank.  
• Always turn cylinder valve on very slowly for  the first 1/4 turn. Turning cylinder valve on too quickly releases an initial burst of pressure that can be detected by the system as a leak and therefore activating the flow control device. 
• Other Solutions: Are burner knobs “On” before opening cylinder valve? Follow proper lighting sequence.  

Problem: Burners will not light 

Solutions: 

• Check to see if propane tank is empty.
• Ensure burner is sitting flat and level in the barbecue and the venturi tubes (tubes that  extend from the burner to the control valves) are properly seated over the orifice(s) on the valve. 
• Ensure burner has been thoroughly cleaned (VERY IMPORTANT).  
• Ensure orifice(s) and venturi tubes are absolutely clear and clean. Check for insects. 
• Ensure igniter is working. 
• Ensure cylinder valve is turned on and the regulator assembly is fully tightened to the cylinder valve. 

Problem: Flame burns out 

Solutions: 

• Ensure barbecue is sufficiently preheated before turning to “Low”.  
• Ensure venturi tubes are properly seated over the orifice(s) on the valve.  
• Ensure venture tubes and orifice(s) are clear and clean. Check for insects. 

Problem: Black smoke on food 

Solutions: 

• Venturi tubes partially blocked causing incorrect gas-air mixture and therefore improper burn. 
• Check and clean venturi tubes.  
• Check air shutters on venturi tubes for  proper setting (gas-air mixture).  

Note: Many are now pre-set at factory and are  not adjustable. Check condition of burner port  holes. 

Problem: Flame too yellow 

Solutions: 

• Check and clean venturi tubes.  
• Check air shutters on venturi tubes for proper setting (gas-air mixture).  

Note: Many are now pre-set at factory and are not adjustable. Check condition of burner port holes.

Problem: Flashback  (Flame burning at venturi, valve, console or knobs) Solutions: 

• Immediately shut off the gas supply at cylinder  valve for propane or at gas shut off valve for  natural gas. Let barbecue cool. Remove burner  and check venturi tubes and orifice(s) for obstructions.  

 Problem: Regulator Humming 

Solutions: 

• This is not a defect or hazard. The noise is internal and caused by cold propane pass ing through a restricted passage. Usually occurs with a full tank in hot weather. Will subside as the weather cools and/or the level of the propane in the tank goes down. Check to make sure there are no leaks. 

Problem: Burner lights with match, but not with igniter 

Solutions: 

• Ensure push button is not broken or wet. • Check to see if wire is broken or frayed. • Check to see if electrode on the ceramic broken, blocked or out of alignment. 
• Ensure batteries do not need replacing.  • Check for obstruction in venturi tubes.

Solutions: 

• Too much heat can be caused by excessive  grease build-up (“Grease fire”), damaged or  missing orifice(s), or a faulty regulator. Another  cause could be that there are too many rocks or  rocks are too close together. 

Problem: Excessive flare-up 

Solutions: 

• Excessive flare-up can be caused by excessive  grease build-up, clogged grease drain, or too  much fatty food on the grill at one time. Drain excess marinade off food before putting on grill.

Problem: Incomplete burner flame

Solutions: 

• Check and see if venturi tubes are obstructed. 
• Check and see if burner is obstructed or  leaking.
