Sorry the one I previously posted is the electric version. Here is the gas version

<div>I would check the blower for cleanliness and voltage.</div><div>
An incorrect air/gas/flame mixture will create explosions. I have had this happen on a Hobart dishwasher and every time it came back to the blower cover rusting and flakes inhibiting the blower wheel from moving the correct amount of air.
</div><div>
In the manual above it explains how to take out the blower and clean it, and check voltage. But that is where I would start. Then start looking and the control modules. It should not ever do that and the machine is designed to not have this happen, i.e shutting off the gas valve if the sensor doesnt see a flame.
Also I would re-check the voltage on your gas valve after re-reading the section of the manual on doing such a procedure as there is a time frame involved on checking voltage.

Interesting post. Does your kitchen have a high negative pressure?
Wat is the manifold pressure?
Is the regulator vent clean?

By you model number, your fryer is a two-vat H55 series high efficiency gas fryer with a built-in filter system.
The “exploding” from your left-hand vat is a case of delayed ignition at its worst.
Instead of typing out all the possible causes, I’m attaching a picture outlining common causes of delayed ignition in those fryers.
BUT…I’m going to go out on a limb and say that you have a cracked burner.
The second picture I’ve posted is what a new burner looks like. There are two of those for each vat. Notice that this burner has four ceramic tiles. All it takes to make a fryer act like yours for just one of those tiles to crack. Very often those cracks are “hairline” in nature and not easily visible to an untrained eye, mainly because that burner remains mostly concealed by its installation until some significant tear-down is performed.
My third picture is a burner (still installed in a frypot) which had actually blown a burner tile in half, which is as bad as it gets.
To address your problem, you need a factory-trained technician to look at it. Ultimately, if your problem can be attributed to a cracked burner, that technician might offer to just replace the burners.
However, once that tech removes the burners, he/she might find cracked burner mounting rails as well (due to heat stress). To replace those rails would require that the vat be removed and to do a complete rebuild of the vat (not something normally done in the field).
A key thing to consider here is that those burners don’t necessarily always just crack outright. Delayed ignition from another issue (see first picture again) might have begun the popping (delayed ignition), and that popping caused one of the fragile ceramic tiles to crack. Then it just gets worse from there.
That’s why I tell folks that a fryer should be taken out of service and repaired whenever there’s even the slightest hint of popping.
Ultimately, at this point you may find it to be most cost effective to just have the frypot assembly replaced.

Of course, this is all simply based on my analysis of your situation as I stare at my computer screen and read what your wrote.

Fullbert, I don’t speak Spanish, but I get that you are having a problem firing your fryer. Not having a full detailed description of what happens when you turn it on, means I have to guess at what you have wrong. I suspect you have a open safety like the drain valve handle not fully closed. This is a copy of the manual if you can covert it to Spanish. I apologize for not being able to find a Spanish version. Check the Manual I’ve attached a link for in section 6 and follow the troubleshooting chart. Beyond that you will need to find a Frymaster tech to solve your problem.

Cula maquina el piloto enciende pero se apaga le reguló el gas pero no se mantiene encendido se sigue apagando no tengo un numero de técnico para llamar ando desesperado ya son dos días sin poder producir +584140983838

Agree, Cracked burner, or loose gasket around it.
Make sure the fan is pulling proper airflow. Check ignition cables for cracking. Check ignition module for proper timing. Check gas valve voltage. Check the solenoid on the gas valve (replaceable).
Use the manual several have posted to follow the sequence of operation. The control/safety voltage goes through several check points before energizing the gas valve. Sequence of operation is key.
