GENERAL INSTALLATION GUIDELINES
All junction boxes and thermostats must be mounted off the
pipe, typically on a beam or a stanchion, to prevent overheating.
All junction boxes, thermostats and transformers must be
located above grade level.
Conduit leading to junction boxes, thermostats and transformers
must be installed so that water does not enter the enclosure.
To prevent water ingress, use an agency approved Class I, Div.
1 sealing fitting with a drain valve. Angle the heating cable cold
lead downward where it exits the insulation.
• To minimize the danger of fire from sustained
electrical arcing if the heat ing cable is damaged
or improperly installed, and to comply with the
requirements of nVent, agency certifications,
and national electrical codes, ground-fault
equipment protection must be used. Arcing may
not be stopped by conventional circuit breakers.
• Needle nose pliers
• 3/16 in. slotted screwdriver
