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
