GENERAL INFORMATION
5. Heaters are mounted directly on any type of noncombustible sur-
face—masonry, concrete, block, plastered walls, metal framework,
etc.— using appropriate hardware.
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property dam-
age. Heater must be installed by a qualified person
in accordance with the National Electrical Code,
NFPA 70.
6. Standard heaters are mounted in a horizontal position with the ter-
minal end on the left.
The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
electric heating equipment. Where the conse-
quences of failure could result in personal injury or
property damage, back-up controls are essential.
1. All wiring should be done in accordance with local codes and the
National Electrical Code by a qualified person.
2. Connect air heaters to same line voltage as on heater nameplate.
3. Check possibility of corrosion if heaters are operated in atmos-
pheres other than air.
4. In general, locate heater approximately 1 foot from the floor, but
not less than 6 inches, for best overall results. Heater, however, can
be located anywhere to meet unique requirements of any particu-
lar application.
