Robertshaw & Honeywell Millivolt gas valvesRobertshaw & Honeywell Millivolt gas valves are powered by a thermopile and do not require an
external electrical source to operate.
Robertshaw Millivolt Gas Valve Honeywell Millivolt Valve
The pilot flame heatsthe thermopile, whichproduces sufficientcurrent to power thefryer’s gas valve.
A thermopile contains bits ofdissimilar metal, which, when heated,emit a tiny amount of electricity.
Alignment of the targets on the burneris critical to the fryer’s efficiency.

The pilot assembly provides ignition for the fryer and heats the thermopile.
The Fenwal thermostat, which extendsinto the frypot, is sensitive toone-degree changes.
