Raypak 003903F Pilot Orifice Kit – Natural Gas IID Models
If your heater struggles to light, has a weak pilot flame, or fails ignition entirely, a clogged or damaged pilot orifice is a common cause. Debris or wear can restrict gas flow and prevent proper ignition.
The pilot orifice controls the flow of gas to the pilot assembly. A clean, correctly sized orifice is critical for stable ignition. Replacing it restores proper flame characteristics and reliable startup.
