Abstract
A modulating thermostat for a gas oven includes a body with supply, main and pilot passages. Feeder passages from the supply passage to the main and pilot passages provide a pilot gas flow for a pilot burner and a minimum combustion bypass flow to a main oven burner. The feeder passages are drilled along paths leading from mouths of the main and pilot passages and adjustment sleeves installed at the mouths adjust the gas flows for particular oven and fuel requirements. A temperature modulating valve assembly in the supply passage includes a valve member cooperating with a valve seat in the body to modulate gas flow and maintain an oven temperature set by rotation of a valve stem at the front of the thermostat. The thermostat is calibrated by rotating a sleeve accessible through the hollow stem at the front of the thermostat.
