Figure 37: AVD Hydronic Coils
All AVD Units (vertical units Size 06-20) have coil connections
located in the unit. The connections are FPT as default, and
M-SWT if selected. There are pilot holes on both sides and the
back of the unit. Piping penetration holes must be field drilled in
the location of the pilot holes. The diameter of the hole should
be no more than 1/2" larger than the pipe, and the gap around
the pipe should be sealed after installation.
