Plenum System
25
Placement of Plenum
SIZES - 20wx24lx36h / 25wx30lx48h

• Subtract 12 from the height of either plenum as
  that portion will be above finished floor. (8
  above finished floor and 4 in SLAB)
• Dig the hole, depending on which size plenum
  width, length, and height -12 deep
• Set initial piece of pipe in the pre-dug trench
  and butt up to plenum
• Mark the top and bottom of the pipe on the
  workable area of the plenum
• Remove plenum from 20x24x24 or 25x30x36
  hole and use the plenum adapter to complete the
  outline of the pipe on the face of the plenum.

26
Installation of Plenum, Steps 6-8
25wx30lx48h
20wx24lx36h

• Cut out marked outline
• Attach plenum adapter per installation guidelines
• Place plenum back in trench

27
Components

• Pipe trench depth
• Plenum and Pipe depth details
• Solving for pipe size and trench depth

28
Pipe Depth
29
Installing Plenum Adapter

• Once the plenum hole is dug along with the trench
  for the system set your plenum in the hole
  butting directly up to your initial run trench
• Place a foam block in trench about an inch away
  from the plenum
• Place your plenum adaptor flange pushed snuggly
  against the plenum and the throat resting on the
  foam block
• Set plenum w/ attached adaptor back in trench,
  level, and youre ready for your first 8 piece
  of pipe
