Orifice Replacement
This unit uses orifice type LH32RFnnn (where nnn
indicates orifice reference size). When replacing unit
orifices, order the necessary parts through Carrier RCD.
See Table 16 for available orifice sizes. See Table 17
through Table 20 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. 62.
