Gas fire place flame to low, do you have a schematic to increase the flame ?

Do they go out on low setting? If so then your regulator is faulty, Never adjust flame higher unless reg. checks out fine. Even then get a qualified tech to do that

did you try bypassing the cycling t-stat also?

Hi there.
The soot or carbon have probably build up inside the fire tubes, better check and have an authorized service technician clean them.
Make sure that the fryer is receiving the rated gas pressure and correct gas type as stated on the nameplate, this way, carbon or soot formation on fire tubes can be prevented
Regards.

Hi there.
You should inspect the fire tubes, it is a tunnel under the fry tank where the burner flames suppose to travel to heat up the oil. Your fire tubes may be clogged with soot or carbon that's why flames cannot go thru the fire tubes. Fire tubes must be free of soot or carbon deposits.
Soot build up on fire tubes can be prevented by keeping the gas pressure at standard as much as possible, low gas pressure produce yellow flame or poor flame quality and in turn will produce soot.
Also, make sure that no air or ventilation is directed towards the flue riser, otherwise, the same will result, flames rolling back towards the door.
Regards.

Ignition Lockout on this unit means #1 that it is set up on propane. If you are low on propane, or were low on propane and just refilled, low/no gas pressure could be the issue. If you ran out of propane, thre is now air in the gas line that needs to be fully blead out.
If propane level is not the issue, replace the ignitor.

The ignitor on these units is also the flame rectifier (flame sensor). If the unit is firing up, but the computer thinks that it is not, then it is not sensing a flame. Replacing the flame rectifier/ignitor will fix the problem in this case.

Several things to check. First be sure the pilot light flame is directly striking the thermocouple. It is a pencil sized rod that is next to the pilot light. Sometimes people reduce the size of the pilot flame to save gas. You may need to increase the pilot flame. Follow the small gas line from the pilot flame back to the gas valve. There is a screw where the small pilot gas line goes into the valve. Remove the screw and then deep in the hole is a tiny screw that can only be reached by a tiny flat blade screw driver. Turn the screw counter clockwise to increase the pilot flame. The thermocouple needs to be red hot to work properly. The second item to check is to see if there are any breezes that occasionally blow through the kitchen. Sometimes the hood fan will draw air under the ovens and actually blow the pilot flame out. Same fix, increase the flame. You may also experience low gas pressure to the appliance during heavy usage. You would need a manometer gauge to check for proper gas pressure. In short, if the oven goes out during your busiest time when everything gas powered is on, the oven may be starved for gas.

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.

close your air vent on the burners it will increase the height of the flame

Its the flame failure device faulty (FFD)

HI thanks for your question. the problem with your gas oven, is the igniter is not hot enough to ignite the gas. a common problem with gas ovens. replace the igniters. thanks the appliance doc. please rate my answer, if happy thanks-
