Thermal Insulation
Raychem-IM-H57548-HWATsystem-EN 16/08
• Splice and Tee connection kits may be installed
above the insulation using the optional SB-04
mounting bracket. The pipe and heating cable ser-
vice loops must be fully insulated as shown above.
Figure 16: Installing connection kits below insulation.
• Make sure that all heat-traced piping, fittings, wall
penetrations, and branch piping are insulated.
Correct temperature maintenance requires proper-
ly installed and dry thermal insulation. Uninsulated
sections of pipe can result in cold spots.
• After installing insulation, electrical codes require
that you install “Electric Traced” labels along the
piping at suitable intervals (10-foot intervals rec-
ommended) on alternate sides.
WARNING: Use only fire-resistant insulation,
such as fiberglass.
