When a Westport's main burner runs rough, burns with an uneven flame, or won't reach proper output, a worn or wrong-size orifice is often the cause. The Burner Orifice #39 Bullet (50-4561) is a genuine Enviro replacement main burner orifice for the Enviro Westport gas stove, sized to meter natural gas correctly at the burner.

Fit

• Sized for natural gas units; propane Westport models use a #53 DMS orifice instead.
• This is the bullet-tip #39 DMS orifice; the #39 long-style orifice is a separate part.

When to replace it

Replace this orifice if the burner delivers a weak, yellow, or uneven flame, since correct orifice sizing is what keeps combustion clean and the appliance operating safely. Gas components that aren't performing as intended should be corrected rather than worked around.

Specifications

• #39 DMS orifice, bullet-tip style
• Threads into the brass elbow; removed with a 1/2 in. deep socket
• Natural gas manifold pressure on Westport units: 3.8 in. W.C.

Installation

Installation should be performed by a licensed gas technician, in accordance with local codes.
