This control, although very similar to the mechanical controls
found on Garland’s current range and griddle models, has
several major economical effi ciencies that off er reliability
advantages to the customer.
It is a safety valve, and thermostat in one assembly, and the
safety valve is away from traditional high heat environment
of the oven burner.
1. The safety valve (should not be removed from the body
of the control for any reason.
2. Familiar Open circuit, closed circuit, and drop out checks
should be made if the internal safety valve is suspected to
be at fault.
3. This control does not require any initial fl ame setting
(currently known as “bypass”). The control has an internal
fi xed bypass orifi ce.
4. This control does not require internal calibration. (Some
minor knob adjustments could be appropriate, but it
would be rare.
5. If a Sit control component is suspected to be internally at
fault, replace the control.
6. Initial gas pressure checks are required to validate that
the control cannot control knob set temperature.
