This is a custom designed switch specifically designed for use in packaged steam generators. The Henry G. Dietz Co., Inc. has hundreds of designs that can be modified to meet the exact required specifications of original equipment manufactures.

The Model 114P was specifically designed for use as an air-fuel interlock switch for use in packaged steam generators. These generators require safe-guards to prevent flow of fuel when a hazardous condition is present due to lack of forced draft. In this event, the fuel shutoff valve is closed and will not reopen until sufficient draft is present. Switch is adjustable over a range of 0.1 to 0.5 inches water column static pressure.

The Model 114P is sturdily constructed and employs a dust free type enclosure incorporating a rubber seal.
