Orifice Replacement
This unit uses orifice type LH32RFnnn (where nnn indicates orifice reference size). When replacing unit orifices, order the necessary parts via Carrier RCD. See Table 11 for available orifice sizes. See Table 12 for orifice sizes for Natural Gas and LP fuel usage at various elevations above sea level.
Check that each replacement orifice is tight at its threads into the manifold pipe and that orifice projection does not exceed maximum value. (See Fig. 34.)
