For appliances using the propane PSE Nova pilot system, this thimble is the correct replacement part for the worn or damaged orifice component in that assembly. The Enviro Pilot Orifice Thimble (part 50-4146) replaces the pilot orifice thimble in compatible propane PSE Nova units.

Purpose

The thimble meters propane to the pilot burner, controlling the size and shape of the pilot flame so it lights and holds reliably.

Key Benefits

• Supports correct pilot flame size for stable ignition
• Helps maintain proper combustion at the pilot burner
• Direct-fit replacement for propane PSE Nova pilot assemblies
• Genuine Enviro part sized to factory specification

Other Notes

Pilot and orifice issues affect how the gas valve and burner ignite and hold flame, so a thimble that is worn, blocked, or incorrectly sized should be replaced rather than worked around. Installation and adjustment of gas pilot components should be performed by a licensed gas technician in accordance with local codes.

When replacing this thimble, it is worth inspecting the related pilot assembly, thermocouple or thermopile, and gas valve for wear or corrosion, since these components work together to govern pilot ignition and flame sensing.
