3. Determine Zone Boundaries

Before tubing is installed, visually inspect the area to determine the

zone boundaries. This helps determine where the first circuit is to be

placed, while identifying any obstacles.

4. Conﬁrm Tubing Requirements

• Measure the distance from the

manifolds to the farthest point in

the zone via right angles.

• 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

of the zone and return.

5. Install Tubing

• Pull one end of tubing off the

unwinderandattachittotherst

barb of one of the manifolds.

• Install using a single serpentine

pattern, keeping the tubing 6"-8"

(152.4 mm - 203.2 mm)

from the edge of the slab.

• Pay attention to the footage marking

on the tubing and cut at the

correct length.

• At expansion/control joints, the

tubing may be passed under the

area or must be sleeved with

Armaﬂex

or PVC to pass through

expansion/control joints (see

Expansion Joints for details).

• Use 1/2" (12.7 mm) tubing for the

radiant ﬂoor.

• Use 3/4" (19.1 mm) or

1" (25.4 mm) Heating PEX or

Heating PEX-AL-PEX for supply

and return lines to the zone.
