When a gas fireplace or stove starts running rich, hunting on flame height, or simply won't respond correctly to the control board after a fuel change, the stepper motor is often the reason why. The Enviro Stepper Motor Conversion Kit (50-4148) replaces the stepper motor used to convert a natural gas unit to propane operation.

Purpose

The stepper motor regulates gas flow through the valve assembly according to signals from the control board. This kit supplies the correct motor for NG-to-LP conversion, ensuring the valve meters propane accurately instead of natural gas.

Key Benefits

• Restores accurate flame modulation and gas metering after fuel conversion
• Supports proper combustion efficiency for the converted fuel type
• Genuine Enviro component, not an aftermarket substitute
• Ships new in original Enviro packaging

Other Notes

Because conversion kits are special order and cannot be returned, confirm part number 50-4148 against your unit's installation manual before ordering. Installation of any gas control component should be performed by a licensed gas technician in accordance with local codes.

This part fits 18 compatible models on record. When replacing the stepper motor, it's worth having a technician inspect the associated gas valve and orifice for wear or fuel-type mismatch at the same time.
