HEATERS, BASEBOARD (KLDR)
This listing covers space heaters of the portable and permanently
mounted types intended to be positioned or installed on or in the wall at
the baseboard level, or on the floor.
Baseboard heaters have been investigated and found to incorporate suitable
safeguards against establishment of fire hazards that might result
from contact with draperies, furniture, carpeting, bedding and the like;
however, discoloration or scorching (but no glowing embers or flaming)
may result on adjacent materials.
Heaters, other than those marked to indicate that they are not for residential
use, have been investigated to determine that the accessible surface
temperatures are low enough to reduce the likelihood of burns from accidental
contact.
Electrical cords, drapes, and other furnishings should be kept away from
baseboard heaters. To reduce the likelihood of cords contacting the heater,
the heater is not to be located beneath electrical receptacles. Listings of
receptacle accessories for use with an individual manufacturer‘‘s baseboard
heaters are included under the category ’’ Baseboard Heater Accessories
² (KLQZ).
Baseboard mounted equipment consists of two types: Complete units
intended for individual mounting in specific locations, and complete systems,
which include accessories to enable the heating units to be interconnected
around the perimeter of a room. Listings for accessories appear
under Baseboard Heater Accessories. With reference to these systems, each
manufacturer is required to furnish detailed instructions covering the
assembly of the basic units and accessories, and indicating the method in
which ground continuity is intended to be maintained between adjacent
sections.
Electrical fittings are provided with each heater of a system to insure
ground continuity between adjacent units and to protect interconnecting
wiring, unless investigation shows that standard fittings which are available
in the field will accomplish the same result.
A system which is factory furnished with all interconnecting wiring, fittings,
raceways, etc., to complete the installation is considered suitable for
connection to a single outlet branch circuit.
