qualified service technician.
Gas Control Knob Settings
Gas Control knob settings are as follows:
OFF prevents pilot and main gas flow through the control.
M2915A
PILOT permits gas to flow to the pilot burner as long as
red knob is held down or thermocouple current is above
the power unit dropout value.
ON permits gas to flow into the control body. Pilot gas is
controlled as in the PILOT position. Main burner gas flow
is controlled by the thermostat and automatic valve
operator(s).
NOTE: Valves are shipped with the gas control knob in
the ON position.
