INTRODUCTION
This design guide and installation manual from Drexan HeatTracer provides recommendations for
designing a pipe freeze protection system for fire sprinkler piping, using Drexan HeatTracer
MultiTrace
cables. It provides system design and performance data, information on heat tracing
monitoring and control, electrical sizing information, and various configuration recommendations.
This design guide assumes the fire protection system has been designed by others qualified in the
art.
MultiTrace is certified to all CSA / UL (CUS) standards for use throughout North America, as well as
ATEX 2014/34/EU for global applications and is suitable for both metal and non-metal pipes, tanks
and vessels. (see p.17).
This guide does not cover the following applications:
• Hazardous locations as defined in the National / Canadian Electric Code
• Supply voltages other than 100-130V or 208-277V
For assistance with application requirements that differ from those addressed in this document,
contact your Drexan representative or Drexan directly at 1-800-663-6873.
The following instructions will provide you with a step-by-step procedure for determining the best
solution for your fire sprinkler system freeze protection applications. An improperly designed and
installed heat tracing system could result in cable failure and possible physical injury.
The installation manual provides general guidance for installing the heating cable and components
on fire sprinkler piping. Additional installation instructions are included with the connection kits,
controllers, and accessories. If you are missing any required documents, you can download them
