The HeatLink® Potable Water System features PureLink® Plus PEX-a tubing, a manifold system, and stainless steel press sleeve connection technology. The unique HeatLink® PEX-a process is based on a method developed during the 1970’s and uses organic peroxide to chemically cross-link the polyethylene during the manufacturing process.
630 psi / 4340 kPa 315 psi / 2170 kPa 80 psi / 550 kPa * PureLink Plus® PEX tubing is listed in PPI TR-4 for these pressure/temperature ratings. Plenum Rating PureLink Plus PEX- a tubing has been tested in accordance with CAN/ULC S102.2-2007/2010, Standard for Surface Burning Characteristics of...
Plus PEX- a tubing is approved for use with fittings that are compliant with ASTM F1807/F1960/F2080/F2098/F2159 standards. When using HeatLink tubing with fi ttings from other manufacturers, ensure to follow all applicable installation requirements and instructions, as well as local building codes to ensure proper connections are made.
Do Not install in contaminated environments. Important Notice! HeatLink products are intended for installation by a licensed plumbing contractor. It is the sole responsibility of the installer to verify that the product meets local codes and standards. Like most plastic material, crosslinked polyethylene is subject to ultraviolet (UV) deterioration and must not be continuously exposed to direct or indirect sunlight, or fl uorescent lights, beyond the stated limits.
(Do Not Use an Open Flame.) Let the tubing cool undisturbed at room temperature. Repair is now complete. Pressure Testing ® Once the plumbing rough-in is complete, it must be pressure tested. HeatLink ⁄ ”, ⁄ ”, 1”, 1- ⁄...
® PureLink Installation Guidelines General Practices 12" ® Install PureLink PEX at least 12” vertically, or Minimum Vertical 6” horizontally away from heat sources such as Distance recessed light fi xtures, or gas appliance vent piping. 6" Minimum Horizontal Distance PEX may be used to connect directly to Power Direct Vent Water Heaters, Electric Water Heaters, or Tankless Water heaters.
> 4.5 d. Heat or cold shrink can be used to seal against moisture in corrosive soil. HeatLink PEX is AWWA C904 approved, and is able to be used as underground water service lines. Expansion (For further details see page 13) Prevent strain on fi ttings by allowing for PEX expansion and contraction.
PEX Tubing Supports Do not use guides that could pinch or cut the tubing; plastic hangers, straps, or clips are recommended, and should be installed to allow free movement of tubing. To minimize strain on fi ttings, manifolds, and multiport tees, PEX should be supported as shown in the diagrams below.

Horizontal runs should be supported by guides every 32” (80cm). Vertical runs should be supported by guides at every fl oor level and midpoint between. J-Clips ® Heat Link...
Expansion & Contraction PEX has a high rate of thermal expansion. Allowance for this must be taken into account during installation. For systems using PEX 1" and smaller the tubing will generally fl ex enough to eliminate the need for expansion off sets so long as tubing is installed as per the guidelines in this manual.
Corner Off set : A 50ft straight run of 1¼" PEX is anchored at one end, and an elbow is Example 1 installed at the other end. It is a DHW supply pipe with an operating temperature of 150ºF, but was originally installed at 70ºF, giving us a diff erence of 80ºF, which equals 4.4"...
Expansion U Off set : There is a 100ft straight run of 2" PEX tubing on a tray in a ceiling Example 2 space for DHW. Again we need to allow for 100ºF of temperature diff erence. In this case a U off set will work best. The equation on the previous page also applies to an expansion “U”, but the arm length (D) is divided into three sections.
Pressing Instructions 1. Cut the PEX tubing to length, ensuring a square ® Pure Link Link Plus cut - an irregular cut may result in a failed connection. For larger diameter PEX an ABS cutter is ® Pure Link Link Plus recommended.
