Coil Piping and Connections
Steam Coil Piping
Air handlers fitted with steam coils have labeled holes for piping penetrations.
Figure 72
illustrates
a typical steam coil piping configuration. See
Table 24
for the codes of system components in these
figures.
The coil condensate return line must be piped full size of the condensate trap connection, except
for a short nipple screwed directly into the coil header’s condensate return tapping. Do not bush
or reduce the coil return trapping size.
