2. Determine Zone Boundaries
Before tubing is installed, visually inspect the area to determine the
zoneboundaries.Thishelpsdeterminewheretherstcircuitistobe
placed, while identifying any obstacles.
3. Confirm Tubing Requirements
• Measure the distance from the
manifolds to the farthest point in
the zone.
• Make sure the minimum circuit length
is at least twice this distance. If not, the
tubing will not be long enough to reach
the farthest point and still have enough
length to return to the manifold.
4. Install Tubing
• Pull one end of tubing off the unwinder
andattachittotherstbarbonthe
supply manifold.
• Lay the tubing along the perimeter
walls to the farthest point in the zone,
keeping the tubing 6"-8" (152.4 mm -
203.2 mm) from the edge of the slab.
This will help protect the tubing from
possible penetrations later on when the
nalfloorcoveringisinstalled.
• Pay attention to the footage marking on
the tubing and cut at the correct length.
• Bend supports may be used to secure
the tubing as it transitions from the thin
slab to the wall.
• In most thin slab applications, built-ins
such as cabinets, showers, and walls
are already in place before the thin slab
is poured. Tubing is generally run around
these “built-ins”.
• Most structural code requirements
restrict the amount of material that
can be removed from a wall member.
It is advised to run the tubing through
doorways, or other openings,
whenever possible.
