Try replacint the regulator and hose, if you haven't already tried it, it is easy to do and not very expensive. If this doesn't work, please let me know.

Low flame on one side


If your grill is older and has seen several seasons check for obstructions elsewhere the venturi is only one place for problems, check for hose kinks loose connections. If this is in a cold weather area, it maybe just low pressure. Also look for collected/ponded water in the burner tubes, especially if the flames are yellow.

My 1100lp when burners are on low flame is to low and make squeeking noise and if a slight bit of wind will blow out flame. I cleaned burner tubes and replaced regulator with factory parts will heat up on...


turn off the LP Tank, disconnect the hose from the tank and wait 5 minutes. Reconnect the hose and turn the tanl valve on very, very slowly, until it's fully open. Light each burner and turn it to high. Wait for the burners to heat up and turn them down gradually to low. If flame height on low has returned to normal, the problem is solved.

If that didn't solve the problem, the air shutters on each burner may need adjusting. Consult the installation instructions that came with the new burners for the proper setting or consult your Owners Manual.

If it's real real cold outside, it's not unusual for the burners set on low to have a problem. The only solution to that is let the grill preheat well, before turning the burners down. Also, grill with the hood closed on low, if it's a windy day.

Hope this helps you and gets you back to grilling again.

My pitco 35 c the flame is burning yellow and not going inside the very wall i thought it might be the regulator pressure on the fryer on the back side


Low gas pressure will produce low flame quality (yellow flame).
Check and remove any dirt or soot on burner holes, and orifice
Burner flame not going inside the fire tube could be due to soot or carbon build up inside the fire tube blocking the flame path, check the inside of the fire tube, if considerable amount of soot is seen, better have them removed.
Yellow flame will cause a lot of problem on fryers if not corrected as soon as possible.
If you have doubt on your gas regulator, better have a qualified service technician to check it.

ON THE CAST IRON BURNERS THERE IS A PLATE WERE THE BURNER INSERTS INTO THE GAS VALVE. THIS PLATE CAN BE ADJUSTED TO ALLOW MORE/LESS AIR TO THE BURNERS BY SWIVELING THE PLATE .CANTHESE BE REPLACED


This 'adjustable plate' is known as an 'air shutter' located at the tips of the venturri tubes which are the tubes that carry the propane from the valve to the burner. These air shutters allow you to control your flame by mixing oxygen with propane to create a yellow flame to a blue flame. The perfect flame is a uniform blue flame with a small yellow tip.

Unfortunately, these air shutters are considered part of the burner itself and cannot be individually replaced. However, if the burner and venturri tubes are separate from each other, you may be able to get a replacement venturri tube without having to replace the entire burner unit.

Hope this helps.

Low flame on burner...


Remove the burner and check the flexible tubes for kinks or blockages. The flexible tubes usually just slip over the backs of the valves. Spiders love to get in there and block them. Also check that the holes in the burners are not clogged. Be careful when reseating the flexible tubes to be sure that they are properly seated on the back of the valves. Failure to properly seat the flexible tubes can cause leakage there, and the gas can ignite at the back of the valves and not reach the burner. Be certain that the replacement burner is designed to use with your grill and the flexible tubes mate properly with the back of the valves.

Low flame even on high


Check the propane regulator if equipped
Check the gas orifices - they may be carboned up and require cleaning
Check the venturi tubes (the tubes that go over the gas jets) - they may have spider webs or other insect cocoons in them
Make sure the gas valves work correctly (high/low)
You mentioned that you replaced the burners - are they correct for the unit and installed ok?
Make sure the gas valve on the propane tank is opened all the way

One burner has low flame


Try looking for webs back to where the burner tube meets the valve. Otherwise you need to remove burner tube to access back of valve to clean with a torch tip cleaner or compressed air, (remember to disconnect grill from gas source first) inside valve orifice.  Usually the back of valve can be removed with a wrench. Worst case you always get a new valve off internet if you can't resolve the plug. Hope this helps, good luck.

Low gas flow - low heat


The only way you can fix the low flame, low heat problem, is to remove the grill, take a medium sized paper-clip (staightened out) and clean out each individual hole on the steel burner, flame tube. (I'm sure there's a technical name for it).

Since they (the holes on the flame tube) face up unprotected, directly under the grill cooking surface they tend to get blocked quickly with continous use and certain foods, like pork ribs. Bad design unless all you plan on grilling is hot dogs.

There are about 500 individual holes, so plan on being there a while. Or in other words, do it close to the cooler.

I've been tempted to toss the thing into the woods a bunch of times over the past 2 years I've owned the dumb thing.

Good luck!

LOW FLAME


hi,

it sounds like something may be blocking the burner tube.
if you can, remove the burner tube and use a long brush or compressed air to clean it out. if you see black soot on it be careful it can make a HUGE mess, and soot is a sign something else may be wrong.

Gas stove top burners


Make sure nothing is blocking burner tubes and burner tops. All holes need to be free and clear. If that dont work replace your inlet valve were your gas lin goes in.
