Description
The SR Series provides an economical means of flame staging where infinite modulation is not required. The SR Series regulator can serve as an alternative to double manifolds on applications requiring dual stages or settings by combining gas pressure regulating and flame staging in a single unit.

Examples of two-stage heating requiring dual gas pressure include direct-fired heaters with two speed fans, high-low control for door heaters, LP-Nat. gas switchover and industrial processing.

All models may be powered by a 24 volt AC transformer. When the coil is energized, the appliance is at low fire. When the coil is de-energized, it is at high fire. Continuous regulation is maintained to hold the electrically set outlet pressure constant against variations.

Note: This product should be installed by a licensed gas fitter.
