DESCRIPTION
Selectra Series 14R electronic gas flame modulation systems
are designed primarily for make-up air heating, as components
of direct fired equipment. They may be field installed on existing
equipment or specified for new equipment installation.
The system uses Modulator or Modulator-Regulator valves,
amplifiers which include low-fire start, and integral or remote
temperature selection and a discharge air temperature sensor that
is mounted within a mixing tube.
