Traced instruments and controls should be insulated in the same manner specified for hot piping, but with a maximum thickness of 11/2 in.

Molded-fitting insulation sections should be applied in sizes sufficiently large to cover both the equipment and the tracers to allow full heat circulation around the entire control or fitting surface.  Small block insulation spacers should be applied between the equipment and insulation to provide firm support for the insulation and allow air circulation paths around the equipment to be heated.

Mineral-fiber insulating cement may be used to insulate heat traced instrument lines or small piping less than 11/2 in.
