Question about Heating & Cooling

1 Answer

Medallion Vermont Casting model CF9080

The burners on my grill do not come to full strength. I replaced the gas tank with a newly filled tank. Since I was having pressure issues, I had the attendant purge air from the tank while he filled it. With 3 of 5 burners lite the flames struggled to stay lite. The temperature stopped at 250 degree after 30 minutes. When I light the side burner it pulls gas from the other burners to a point where they almost extinguish themselves. I can't see an clogged lines. The outside temperature is 40 degrees. Could the regulator be an issue? What else should I do? Thanks, Harcourt

Sounds like the regulator. there isn't much of anything left to go wrong! the gas comes out of a very small orifice in the burner tube and mixes with atmospheric air before being burned at the jet.

Uneven burner


I apologize I've not logged in for some time and do not know what "everyone else" has had issues with.
I can tell you as a grill repair company we get 4-5 calls every week from clients complaining of poor flames, poor heat. The problem has a very simple solution and the problem is not the burners or other parts and (almost never) the regulator.
There are 3 safety features in an LP cylinder. One is a check valve that gauges pressure leaving the tank. This is a swing-arm pressed up by escaping LP. When the gas fills the manifold and gas line (because the BBQ valves all Must Be Off when the cylinder is turned on) the pressure pushes this swing-arm back into position.
The problem usually occurs with newly filled tanks because with the tank full and the OPD float displacing liquid pressure the gas "hits" the check valve swing-arm too hard so instead of registering the pressure leaving the tank the swing-arm is pressed too far and the back-pressure does not reseat it correctly.
The mechanics of the tank are designed to read higher pressure leaving and lower pressure returning as a leak and shuts-down. We still get some flow because of the OPD pushing but the tank will not allow gas flow at the necessary BTU's.
Reset: Turn off everything on the BBQ and the LP cylinder. Disconnect the cylinder and turn the BBQ valves all to "high".
Wait 5 minutes.
Turn everything off again -- and be sure every valve is completely off so no pressure is released.
Reattach the LP cylinder to the regulator and turn the tank on -- very, vert slow for the first full rotation so the gas pressure leaks through slow and cannot "hit" the check valve too hard.
Once the cylinder os all the way on light the BBQ and it will be fine.

Please let us know how it goes.
If I had one dollar for every time someone contacted us to buy burners, regulator, etc only to fix their BBQ while on the telephone with us ... I would retire!

Low flame at burner. I've put a new tank on my grill and now the flame stays very low on all burners. I've heard that there can be some pressure problems with a newly filled tank. Is there a quick...


Mike, there can be some pressure problems, but it's not the new tank. However, it does cause the problem and here's how you resolve it.

1. Turn the gas tank valve OFF.
2. Disconnect the hose from the tank and wait 5 minutes.
3. Reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow).
4. Once the valve is fully open, light the burner farthest from the tank first and turn the burn to HIGH.
Does the burner light and the flame height look correct? If so, light the remaining burners the same
way. Now, do all the burner flames look as the should? If co, you solved the problem. Always
remember to turn the tank valve ON very, very slowly>

If the above did not solve the problem, you will need to replace the grill's Hose/Regulator Assembly. You can pick one up at any home center or hardware store that sells gas grills and accessories. It will run you about $30.00 (+/-) .

Hope this helped you to solve the problem Please let me know & Happy Grilling!!

Grill does not get hot. I have a fresh bottle of propane. Hose is not kinked. Grill is maybe 6 - 10 years old.


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.

Cant get grill to light. newly filled gas tank.


Hello,
You may have turned the gas tank valve on too fast. Close it, disconnect it and reconnect it. Then very slowly turn the tank valve back on and only light one burner at a time. If this doesn't solve the problem, let me know by leaving another comment on this post and I'll dig deeper with you. Douglas

NO GAS FLOW INTO BURNER TANK FULL. ALL CONNECTIONS OK. NO GAS FLOW TO BURNER


Hopefully it is something simple like turning on the full tank too fast. Turn it off, disconnect it, reconnect it and turn tank valve back on very slowly. If this doesn't resolve the issue, click on my username and scroll down my profile to my tips and tricks for gas grill lighting issues. One of them should help.

Gas not coming out enough; flame not catching on to other burners


Problem: Low flames on grill, tank is full.

Cause: These newer tanks have a device inside that limits the flow of gas to prevent leaking or accidental discharge of gas from the cylinder. The leak detector mechanism inside the tank shuts off the gas whenever the valve is opened rapidly.

Solution:
Close the tank valve and remove the tank. Check the gas line for ANY object that could cause blockage. Open all valves on the grill to eliminate any pressure whatsoever. Close all valves and reattach tank. SLOWLY open the tank not over 2 turns. Check for leaks. I just open my tank a tiny bit but that is just me.

This late model gas grill service manual has more details on page 13.

My weber gas grill suddenly does not heat up enough. It has been working for two years and suddenly the amount of flame is tooooooo small to cook.


Hello. You may not have enough propane left in the tank for it to work properly, you may not have turned the tank valve to the full open position, or your valve safety device may have kicked in. IF this last item is what happened read on:
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 the grill, side burner, rotisserie, etc on high for a few minutes with the hood open before turning all the valves back to the off position.
  • Make sure. Most gas barbeque 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.
When the propane gas tank is new or newly-filled, the gas is full and the OPD is pushing slightly on the top filled area and the gas will want to burst through the valve. Slow it down by turning the valve on slowly and the check valve will reset itself.

Jenn Air grill burners only lite on one side


It could be a bad regulator but,highly unlikely . Check your air shutters at the end of the burner tubes and adust them properly.And if you have a OPD propane tank you maybe turning it on to quick causing the check valve inside the gas valve to open half way. Try opening the valve slowly.

The grill won't light although I have a newly filled tank and have used it once with the filled tank with no problem. This is a Weber portable grill.


This is kinda long but it should help you fix your issue:

How long has the grill sat since the last time you used it? If it has sat more than 4 months, check the tank to make sure it still has gas in it.

How did you shut the grill off that first time? Did you turn the burners off and then turned the tank off? If this is what you did, your grill is now "vapor-locked"; don't panic, it is easy to fix!

All you need to do is: 1) Open the tank's valve. 2) Open the burners to high. 3) Close the tank valve. 4) Turn the burners off.

Once you have done this, re-open the tank's valve, then turn the burner on to light the grill. If it doesn't light, repeat the above procedure and try again.

If it still won't light, you may have a bad regulator. You can buy another regulator and test the grill with it; if the grill lights, it was a bad regulator...if the grill doesn't light, you can always return the purchased regulator and get a refund as long as you kept the receipt.

If all of this hasn't fixed it, check your gas lines for any sign of cracking which can contribute to gas leakage. Check your burners, if they are rusty, take a paper clip and run it through each burner hole to clear any obstructions.

If none of this has fixed your issue, you may need to either get replacement parts for your grill or buy a new grill...that choice would be up to you, tho.

I sincerely hope at least SOME of this will be helpful to you...good luck!
