If a gas insert or stove is running rough on propane, cycling unevenly, or failing to modulate flame height correctly after a fuel switch, the stepper motor is often the cause. The Enviro Stepper Motor LP (part 50-3753) is the genuine Enviro component designed to replace or install into the gas control system when converting a unit from natural gas to propane.

Purpose

This stepper motor kit governs the metering of gas through the valve on Sit Proflame 2 systems, and is required specifically for the natural-gas-to-propane conversion process on eligible models.

Key Benefits

• Restores accurate flame modulation for consistent heat output
• Supports proper propane combustion efficiency after conversion
• Genuine Enviro part, built to original fit and function
• Ships new in original Enviro packaging

Other Notes

Because this is a special-order part that cannot be returned, confirm the part number against your appliance's installation manual before ordering. Installation should be performed by a qualified gas technician in accordance with local codes.

When replacing the stepper motor, it's worth having a technician inspect the associated gas valve and pilot assembly for wear, since these components work together in the same control system.
