Hello. What you are dealing with is due to the new safety feature on your tank. Do this. Turn off the tank and disconnect it from the grill. Then reattach the hose to the tank and VERY slowly open the tank. This should solve the problem. ALWAYS open the tank very slowly from now on. J.

I have a Kenmore 14116329 propane grill. The propane tank is full but when I turn on the burners very little gas comes out resulting in a VERY low flame. Is it the regulator or???


It is most likely the saftey check valve in the tank. The procedure is to:
  • Close tank valve.
  • Disconnect hose connection from grill to tank.
  • Wait
  • Reconnect hose connection from grill to tank
  • "Slowly" open valve on tank to release gas back into grill
Through on some steaks

If still a problem replace tank.
The check valve that can cause your problem drastically reduces propane flow in case of an accident and the lines are ruptured
Hope this helps?

GAS FLOW TO THE B/B/Q BURNERS


Three possibilities come to mind. First, is the propane tank full? Second, is the valve on the tank open all the way? Last, is there any obstruction in the lines such as spider webs. Spider webs can even make a furnace not run. This could easily cause low flow issues.

We replaced the regulator and the grill still does not have big flame always seem to be on low despite knob adjustment


Turn off propane. Disconnect propane tank from barbecue. Open burner valves for about 20 seconds. Close valves. Reattach propane tank. Slowly open propane tank valve. Turn on burner and ignite

Low water pressure


Hi Bob,

You can determine if the tank is the problem by connecting a garden hose to the drain that is provided on most water heaters. Before doing this, be sure to shut of the electrical supply to the heater - otherwise you can damage heating elements if an electric type or waste fuel by heating an empty tank if a gas / propane fired type.

If you get a slow flow out of this drain, it means that somewhere in the cold water supply side to / in the tank - there is a problem. Inside the tank, the cold water is delivered by a "dip tube" that distributes the cold water to the bottom in the tank. Dip tubes are used in both electric and gas / propane fueled heaters. Here's a cut away view of a typical tank:

If the tube is clogged, or there is build up, scale or debris in the supply (cold water) side of the heater, flow rates will suffer. Likewise, if there is a problem with the output of the tank, it will directly affect flow as well.

If you get a good flow rate from the drain, then the issue is going to be on the hot water output side of the heater. Again, the same build up, scale, debris issues on the hot water out put pipe will cause problems with flow. Typcial tanks do not have dip tubes for the hot water side of the tank - as taking hot water from the top of the tank is most desireable and is furthest away from the cold water that rushes in to make up the hot hot water going out.

There's nothing really in the tank itself that can cause issues with flow outside of the dip tube, and piping to and from the tank.

Good luck!

Low flame - even at full power. Help! Propane tank is full.


there is a high flow check valve in the regulator designed to prevent large amounts of propane from escaping. sometimes this gets activated by turning it on with the burner valves open. 1. turn tank valve off 2. open burners .3. close burners after 10 secs. 4open tank valve slowly.

I have full propane, yet a low flame?


he new style OPD valves have a small brass ring located in the female fitting on the LP tank. Over time this ring can work loose and then it does not allow the male fitting to fully depress the OPD valve thus reducing your gas flow
Using a small flat bladed screw driver tighten the small brass ring This should solve your problem

Flame is low when turned on highest setting


There are a few causes for that.

1. You are low on propane.
2. Your propane tank is overfilled, and the overfill protection device is restricting gas flow.
3. You have turned off your grill using the propane tank instead of the control valves on the grill. This may also cause the overfill protection device to engage. You can reset this by turning off your control valves on the grill, turn off the propane tank, unscrew the hose from the propane tank, then put the hose back on securely, turn on the propane tank and turn on the control valves.
4. Your burners are very rusty and may be clogged. Clean or replace the burners.

Low flow of gas to 1st burner, if second burner is turned on flame goes out. bottle full


First disconnect tank. Hook back up and open very slowly. These new valves on tanks have a shut down if you open valve to fast, causing tank valve to think it is leaking, it slows down flow of propane. Always open tank valve slow when turning on grill. If this does not solve problem then regulator is going bad and need to be replaced.

My propane ank is full, but when I turn it on high, the flame is barely lit. When I change it from high to low and back to high, the flame level never changes.

Genesis s310 stainless grill. Does not fully light.


Regulator is not bad, as I stated before new valves are designed to reduce gas flow if valve is opened to fast. This is so if grill catches on fire, the tank will shut itself off, thus propane will stop flowing causing fire to extinguish itself.
