3. Master Jet Fryer Robertshaw & Honeywell Millivolt gas valves Robertshaw & Honeywell Millivolt gas valves are powered by a thermopile and do not require an external electrical source to operate. Robertshaw Millivolt Gas ValveHoneywell Millivolt Valve

4. The pilot flame heats the thermopile, which produces sufficient current to power the fryer’s gas valve.

5. A thermopile contains bits of dissimilar metal, which, when heated, emit a tiny amount of electricity.

6. Alignment of the targets on the burner is critical to the fryer’s efficiency.

7. Burner components A structural standoff is provided on later MJ series fryers.

8. Orifices Pilot Assembly Burner components The pilot assembly provides ignition for the fryer and heats the thermopile.

9. The Fenwal thermostat, which extends into the frypot, is sensitive to one-degree changes. Fenwal Thermostat
