Heating Cable Installation (Cont.) CHECK FOR PROPER INSTALLATION 1. Before installing the thermal insulation, inspect the heating cable to verify damage did not incur during installation including any thermal damage or other disturbance which may have occurred if exposed to a excessive heat. INSTALL THE THERMAL INSULATION 1. The heat trace system requires weatherproofed thermal insulation installed as shown in Figure 3. 2.
