Introduction and Dimensions

Selectra SERIES 14 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. Natural, manufactured, mixed, LP
and LP gas air mixture are compatible gases.

The systems utilize Modulator or Modulator-Regulator
valves. Amplifiers are available with adjustable low-fire
start duration, and with integral or remote temperature
selection. A discharge air temperature sensor is mounted
within a mixing tube housing.

Optional - a room override thermostat provides space
temperature control by raising the discharge air temperature
to a pre-selected point - when used in conjunction with the
remote temperature selector.
Optional - an inlet air sensor (and mixing tube) provides
inverse change in discharge air for each degree change in
inlet air - when installed in a convenient duct location
upstream of the burner.
Optional - a dual temperature selector replaces TD114 to
provide dual control for door heaters, or other applications
such as paint spray booths (TD214_ or _X, or AD1214_).
