Any listing in this product directory or other related materials, where “NRTL” appears next to the product name was tested by ARL as a NRTL.  The NRTL status for these listed products was valid through January 27th, 2008 unless previously delisted.  These products may remain listed solely by ARL. However, they are no longer under the surveillance of the NRTL program.

FIXED AND LOCATION DEDICATED ELECTRIC ROOM HEATERS

The products listed here are fixed and location dedicated electric room heating equipment rated 600 volts or less to be employed in ordinary locations in accordance with the National Electrical Code, NFPA 70.

The requirements for this category do not cover movable heaters, wall or ceiling hung heaters, baseboard heaters, duct heaters, central heating furnaces, fan coil units, panel or cable type radiant heating equipment, electric boilers, or any other electric heating equipment or appliances that are covered in or as a part of separate, individual requirements.

A location dedicated heater that is considered likely to be operated as a movable heater has also complied with the requirements for movable heaters.

If the operation of a heater involves the generation and confining under pressure of steam or other gas, consideration has been given to the possibility of risk of explosion incident to such operation.  This applies in the case of an appliance having immersed electrodes, if the electrolysis of water may result in the accumulation of oxygen and hydrogen.  The appliance is not acceptable unless its strength is such that it will withstand any risk of explosion that may be involved.

Each product is permanently marked, in such location that the marking is plainly visible (after installation in the case of a permanently connected appliance), with (1) (manufacturer)’s name, trade name or trademark, (2) the catalog number or the equivalent (3) the date or other dating period of manufacture not exceeding any three consecutive months, (4) the electrical ratings of each circuit to which a supply connection is made and (5) hazard and other warnings as required by the standard.  A heater intended for use on alternating current only or direct current only is marked to so indicate.  If a (manufacturer) produces or assembles heaters at more than one factory, each finished heater has a distinctive marking - which may be in code - to identify it as the product of a particular factory.  A heater whose acceptable performance depends upon its proper location or position is marked (such as “Top” or “Bottom”) to indicate the way in which it is to be installed or used, unless such position is obvious from the external appearance of the heater.

These products comply with ARL requirements which include pertinent sections of the Standard for Safety, ANSI/UL 2021, Fixed And Location Dedicated Electric Room Heaters.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements of the standard, and that involve a risk of fire, electric shock, or injury to persons, have been evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of the standard.  A product whose features, characteristics, components, materials, or systems conflict with specific provisions of the standard have been judged to be in non-compliance with the standard.

Only products which properly bear the ARL Listing Mark (Label) are considered Listed by ARL.


NOTE:

Delisted products appear with a double strike through and “DELISTED” after the report number.
Deleted/revised models for listed products appear with a single strike through.
