Install Instructions
External Temperature
Soldering. Soldering shall be performed minimally 18"
from installed PowerPEX tubing unless a heat-trapping
device is employed. Make all sweat connections and
allow cooling prior to making PEX connections to
PowerPEX tubing.
Duct Work - Heating. Tubing shall be insulated from
direct contact with heat transmission ductwork that
has a possibility to exceed the maximum tubing working
temperature of 180°F. Tubing shall be kept 6" from
gas appliance vents except those vents with a thermal
protection approved for installation near plastic (PEX)
tubing as explicitly called out by the manufacturer. In
horizontal tube installations, keep tube 6" away from
heat source.
Water Heater Connections. Connections to tubing shall
be made minimally 18" from the water heater hot and
cold connections on gas water heaters. Connections to
tubing shall be made with metal transition ttings. See
Sioux Chief Water Heater Connections section (www.
siouxchief.com)
Heat Lamp + Lighting. Tubing shall be kept minimally
12" from heat source and proper protection shall be
used to avoid overheating tubing. Keep tube protected
and 12" from recessed lighting when installed in vertical
alignment to heat source. If 12" distance is not available,
proper insulation should be used to protect tubing where
insulation maintains the necessary heating certications
for the application. PEX must be protected from any UV
light-producing device.
Frozen Tubing. PEX tubing should not intentionally be
frozen. The frozen section of tubing and the general
area should be protected from further exposure to
unadvisable installations. Heat the affected area or the
blockage assuring that tubing does not overheat. Use a
hand to test surface. Space heaters, warm towels,
or warm water submersion are acceptable means to
thaw tube.
Welding. Do not attempt to weld or fuse tubing.
Kinked Tube. Remove Kinked sections or sections of
pipe that have exceeded maximum out-of-roundness.
