Hi,
When a new or newly filled propane tank is attached to your gas grill, the OPD is usually at its maximum limit position above a tank filled to capacity. Propane may come through the valve too strongly due to the additional pressure of being full and the OPD displacement. The propane tank goes into check and limits gas flow when too much pressure hits the valve. Some grill manufacturers provide instructions for this in the users manuals but most people do not read the manual. Many grillers believe replacement parts are needed and burners, ignitors and regulators get replaced without reason. Depending on how efficient the grill is operating, some grills attached to a tank in check will not ignite and others will light but cannot reach cooking temperatures because the tank has limited the amount of propane released. Sometimes the food will be unable to exceed 200 degrees in temperature because the propane tank is in check.


Gas grill replacement parts are available and are sometimes necessary, low or no gas flow indicates a different typr of repair. Most grillers accept instructions and the problem is corrected in minutes -- but believe it or not I have had a few insist on purchasing replacement parts.
How do I fix grill?
To reset the check valve and get back to cooking on your gas barbecue grill, first
turn everything off. Turn off the grill, the rotisserie, the side burner and the LP gas cylinder tank. Once everything is turned off disconnect the propane tank from the gas grill regulator by unscrewing it or pulling the quick-release on older or retro-fitted propane cylinders. Now turn the grill on. I know, it is dis-connected from the gas tank but we want to ensure that the pressure in the gas lines or any gas in the burners is released. Leave all grill burners in the on position for 3 - 5 minutes before turning them off. Make sure. Most gas grill valves must be pushed in to turn them and if turning is attempted without pushing the knob, they will not turn to the "on" position. With the grill, et al turned off reconnect the propane tank and slowly turn the hand wheel to the open position.
Slowly. The trick here is to turn the hand wheel slowly. Propane in a new or very full tank will be under more pressure, especially with the OPD floating in position. The extra pressure will come through the tank valve stronger. Turn the gas tank slowly allowing small increments of propane to enter the grill.


Once this is complete, you should be able to turn the grill on high and ignite your gas grill burner. Your cooking heat should be back to normal and cooking times decreased. If the problem persists, try this process again to make sure you followed every step. The check valve exists to save your life if there is a leak in any of the gas fittings. Constant check valve issues could imply a gas leak and a visit from your local gas grill service technician may be necessary.
To find a leak, turn the grill valves to the off position and the gas tank valve to the full on position. This should pressurize the gas line. Spray soapy water on all the fittings and look for bubbles just like checking for the leak in a flat tire.
Do not attempt to correct a gas leak on your own. While a check valve error when your gas grill will not get hot or will not ignite is a user education error and an issue corrected by learning about your propane tank, a gas leak should be corrected by a licensed gas service technician. When you are grilling, turn the propane tank on first and then turn on your grill. When you are done cooking, turn the gas tank off first and then turn off the grill valves. The process releases the pressure in the gas grill hose and manifold which allows the gas tank to release pressure by filling these lines. Read the safety features of your gas grill, clean it when necessary and replace used and failing parts. Aside from that be safe, eat well and have fun.

thanks.

Hooked up proane tank used once then no flame on grill. There is propane in the tank but no propane flows out of it either when hooked up to the grill or when opening the valve directly on the tank. This...


The valve on the tank has an internal valve that will not allow you to release propane into the atmosphere. It must be connected to a regulator line in order to open.
It sounds like your regulator has failed. Remove the regulator assembly, inspect it carefully for blockage or hose kinks. If there none, try replacing the regulator assembly.

Heats to only 300 degrees? i have replaced everything, sugestions?


This is a common problem with grills purchased after 2001. There is a new safety feature inside the regulator called a 'surge protector'. If you open your propane bottle valve too quickly or if you try attaching a tank with the tank valve in the 'open' position, the propane wants to 'surge' into the grill.

When the propane surges into the regulator (located on the grill hose) the 'surge protector' (inside the regulator) kicks on. When this happens you will not be able to get your grill lit, and if you do, it will be a small blue flame and the grill will not heat up.

So what to do if you trip the surge protector and can't get your grill to light or heat up?

Shut the tank off and shut the valves on the grill off. Disconnect the tank from the grill hose. When you disconnect the tank from the hose you will hear the excess pressure of propane release. This is an indication that you have re-set the regulator's surge protector.

Now that you have deactivated or reset the surge protector, reconnect the tank. Make sure the valve on the tank and the valves on the grill are in the closed and in the off position. After you reconnect the tank to the hose, SLOWLY open the tank valve (making sure the valves on the grill are in the OFF position).

Since you have slowly opened the valve on the tank, the propane did not surge into the regulator and the surge protector did not activate.

Now open 1 valve on the grill and light it. You should get a nice flame. If your grill has more than one valve, open each following valve in sequential order to extend the flames to the other burners.

Thanks for reading and I hope this helps.

Propane gas flame is not hot. Do I adjust the air


Here is something to try if it is LP Gas:

Here is a Tip to fix a grill that not getting hot:
1. Turn the gas valve knob off. then close LP tank valve knob.
2. Unscrew the plastic hose coupling knob from the LP tank. You may hear a slight "hissing" sound as pressure is released this is normal.
3.Wait a minute then screw the coupling knob back on to LP Tank.
4.With lid open.slowly open LP tank valve.
5.Relight the grill the proper way by turning gas valve knob to ON position while turning the igniter knob at the same time.
6.After you are sure the grill is lit preheat the grill for 30 minutes.

This was called purging the line or releasing the air out of the line.

Another thing your orifice could be clogged with spiders or dirt. If it is LP gas check to make sure your hose is not kinked.

Very little gas getting to burners Full bottle of propane Acts the same way as when the propane bottle is getting empty This grill is only about 6 months old


You either have clogged burners and they need to be cleaned. Clogged inlet line to the burners. (This can come from trash, spiderwebs etc in the connection, kinked line etc.) or the regulator is malfunctioning.

Burners will not light


Check to see if the bottle is full or empty ? could be a number of problems . Bottle empty ? bottle wasn't purged properly or you may have spiders that have nested in the propane lines which is a common problem.

No propane flow to grill using bulk bottle system.


the office that is open on the bottom of the burner sound like a spider has taken home to.. the hole.... This happened to mine. a small pipe cleaner or wire will break it up...try that. also did you feel the top of the tank regulator and see if it has froze. try turning the tank upside down and turn the unit on.... this may also help by forcing the spider debris out.

What would cause ice crystals to form on propane line


Bad hose, bad tank, or seals are gone. Recommenend buying a new tank and new hose. The Ice is from the propane freezing and the hissing noise is a leak from somewhere. Better to replace tank and hose and try again. You do not want to take a chance with propane
