Preface/Scope

SCOPE

1.1.1
This standard applies to newly produced gas appliance thermostats of the integral gas valve type having a maximum operating gas pressure of 1/2 psi (3.48 kPa) or electric type (see Part IV, Definitions), constructed entirely of new, unused parts and materials.

This standard does not apply to an electric type comfort heating thermostat (wall-mounted) for installation remote from an appliance.

When the operating performance characteristics of the thermostat can be affected by the separate components, such as power supply, transformer
and valve(s), the thermostat shall be tested as part of a complete system.

Compliance of a device with this standard does not imply that such device is acceptable for use on gas appliances without supplemental tests with the device applied to the particular appliance design.
