This stepper motor/tower fits 19 compatible Enviro models on record, spanning many of the brand's gas stove, insert and fireplace lines. The Enviro NG Stepper Motor/Tower (part 50-3870) replaces the worn stepper motor and tower assembly used in Propane-to-Natural-Gas conversion kits on compatible Enviro appliances.

Purpose

The stepper motor/tower drives the mechanism that adjusts fuel delivery when a unit is converted from LP to NG, keeping the gas control operating to factory specification for the selected fuel type.

Key Benefits

• Genuine Enviro component built for long service life under regular cycling
• Restores reliable fuel-type switching function in conversion kits
• Ships in original factory packaging, not a reproduction part
• Direct-fit replacement for the original stepper assembly

Other Notes

Because this part is used in fuel-conversion systems, installation and gas setting adjustments should be performed by a licensed gas technician in accordance with local codes.

When replacing the stepper motor/tower, it's worth inspecting the associated gas valve, pilot assembly and related switches in the conversion kit for wear, since these components work together in the same fuel-switching circuit.
