Napoleon W175-0383 Natural Gas to Propane Conversion Kit for BHD4/CBHD4

Precision Fuel Conversion for Ascent™ 42 Series

The Napoleon W175-0383 Conversion Kit is a precision-engineered set of components designed to transition the Napoleon Ascent™ 42 (BHD4) and Continental CBHD4 gas fireplaces from natural gas to liquid propane. Because propane operates at a higher energy density and requires different manifold pressure settings than natural gas, this kit is essential for re-calibrating the burner system. It ensures the fireplace continues to produce a safe, stable, and clean-burning flame following a fuel source change.

Genuine Napoleon OEM Reliability

As a factory-authorized accessory, the W175-0383 kit includes high-quality brass hardware and regulator components manufactured to strict tolerances. Using genuine OEM parts is critical for maintaining the safety certifications of your fireplace and ensuring that all thread patterns and aperture sizes perfectly match the original valve assembly. This kit provides a seamless transition while preserving the longevity and high-efficiency performance of your Ascent™ series fireplace.
