Well, I suppose I ought to explain some about this install.
First of all, the fryer cords connect outside of the hood. This means that they will NOT be turned off when the Ansul system is operated.
The immediate problem, though, is the presence of the cord connections and GFI unit just above the fryers. When food is placed in the fryer, a great deal of moisture / oil enters the air. This will then condense on anything in it's path that is cooler. TRhat would include "cold" electrical connections.
Condensing moisture would allow current to leak across the face of the plug, to both the neutral and ground prongs. The GFI would see this, and trip.
Simply re-locating the connection outside of the condensation area eliminated the problem. (Of course, this was done without using extension cords, etc.)
None of the electric has been tied into the Ansul as yet; a bid has been submitted.

I've only installed a few "Ansul" systems, Iwire, so I am no expert. However, here it is required, when the system is tripped, that ALL sources of ignition be disconnected, as well as make-up air be stopped. This meands that the lights under the hood, any receptacles, and all electric equipment be shut off- in addition to the gas being shut off.
You are quite correct; the circuit only powered the controls and the gas igniter. Were these deep fryers to be all electric, they would likely need a 100 amp circuit. (Bit much for that extension cord!)

It is similar here, the last ansul I wired killed the make up air, the hood lights, and ran the exhuast fan for 30 seconds then shut it off. As the range was gas fired there was a cable operated valve that was tied into the trigger mechanism.
