OrificeReplacement
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 10 for available orifice sizes. See Table 11 and
Table 12 for orifice sizes for Natural Gas and LP fuel
usage at various elevations above sea level.
Check that each replacementorifice is tight at its threads
into the manifold pipe and that orificeprojection does not
exceed maximum value.See Fig. 32.
