What it is
This is a natural gas (NG) orifice supplied by Navien under part number 20030525A, marked 4.8_ 6.6. It meters the gas flow into the burner on Navien NPE-AWE and NPE-SWE CE-32 series boilers, so the correct orifice is essential to achieving the specified gas rate and combustion figures.
Signs this part needs replacing
- Combustion readings outside the manufacturer's stated range for natural gas
- Sooting, discolouration or a lazy, yellow flame at the burner
- Flame lift, instability or a rough light-up that persists after servicing
- Gas rate that cannot be set correctly at the meter or via the appliance's setting procedure
- Orifice visibly blocked, damaged or marked differently from the specification
Before you order
- Confirm the appliance model and serial number against the fitment list above
- Confirm the appliance is running on natural gas, as this orifice is for NG
- Check the marking on the existing orifice matches 4.8_ 6.6 before ordering
- Check whether more than one orifice is required for the appliance being serviced
