FIREROD® Product Guide
WARNING – Risk of Electric Shock –
The installation and wiring of this product shall only be done by
a qualified electrician, in accordance with applicable national and local electrical codes. It is the end
user’s responsibility to ensure that proper precautions are taken in reference to applicable personal
safety equipment needed by those installing and maintaining equipment.
Never interrupt the protective earth circuit/ground. Any interruption or disconnection of the protective
earth circuit used by this product will create a dangerous situation and could result in an electric shock
that in some situations could lead to serious personal injury or property damage. It is the user’s
responsibility to properly size the ground wire for the protective earth circuit/ground and to ensure
that the impedance of such wire is low enough to avoid dangerous conditions.
In some equipment or installations a GFI style breaker or circuit should be installed to ensure the safe
operation of the product. Determining if this is a requirement is the responsibility of the user.
The mains/line voltage applied to the product must always be equal to or less than the voltage rating
marked on the product’s name plate/label.
Some heaters are supplied as dual voltage (e.g. 240V / 480V) units and hence the user should check
the wiring diagram to ensure that the product is wired correctly for its supply voltage.
Thermostats should not be used as an “OFF” or disconnect device. The use of a disconnect switch or
circuit breaker is highly recommended and will allow the isolation of the product when maintenance is
required
Minimum Circuit Requirements
WARNING –
It is the user’s responsibility to properly size and install the feeder wires to the product.
Feeder wire should be properly selected based on amperage, electrical power rating, ambient
temperature, and type of environment.
It is the user’s responsibility to ensure that the bending radius of the products and/or any conductors/
cables and coverings (even if supplied by Watlow) are large enough to prevent any damage.
For components that do not already have insulated supply leads provided, user must take suitable
action to either add suitable insulating sleeving or equivalent (with appropriate temperature and
environmental rating) to suitably cover any exposed conductive surface.
