lined out below.
A cord-connected heater shall be provided with a pilot light having a non-user-replacable lamp (e.g. LED) or lens that glows red or amber. The light shall:
Exception No. 1: A pilot light is not required if a visibly glowing heating element of a radiant heater can be considered to serve as an indicator that the heater is energized. A heating element is considered to serve as an indicator if:
Exception No. 2: A pilot light is not required on a commercial/industrial heater.
Exception No. 3: A pilot light is not required on a hearth type heater having a flame effect feature. The flame effect feature shall have a majority red or amber color, be illuminated by at least two lamps and shall comply with the visibility requirement of 13.6.2. The flame effect feature shall be connected to the heater circuit so that it is energized whenever the on-off switch (see 28.11) is in the on position. Compliance of the flame effect feature shall be determined in all operating modes when the on-off switch is in the on position.
With respect to the conditions for Operation Tests, Section 37, and Abnormal Operation Tests, Section 41, if operation of the heater in accordance with 37.1 could result in a risk of fire or electric shock due to overheating of the heater, a thermal cutoff or a manual reset type temperature limit control shall be provided. If a manual reset type limiting control is provided, it shall be of a type that will not operate as an automatic reset control when the reset means is held in the reset position.
Exception: An automatic reset type temperature limiting control or a manual reset type limiting control that operates as an automatic reset type when the reset means or actuating member is held in the reset position may be used as a control to limit temperatures for the heaters specified in (a) – (e) below.
A heater intended for residential use that is provided with an over-temperature limit control shall include an audible or visual alarm to indicate that the limit control has operated. See 25.2 and 25.3. The alarm shall become energized when the limit control functions to de-energize the heating elements. For an automatically-resetting temperature limiting control, when the temperature limiting control reconnects electric power to the heating element (s), the alarm may be de-energized or it may remain energized until de-energized manually. For a manual-reset temperature limiting control that operates as an automatic reset type when the reset means is held, the alarm shall remain energized until the temperature limiting control is reset.
Exception: Heaters that use the following types of temperature limit controls:
|56.2||Production-Line Grounding Continuity|
This test is also required for permanently-connected units, including accessories for such units that derive power by means of internal cord and plug connection.
|60.1.8||The instructions described in Sections 60.2 – 60.5 may be provided as separate documents or combined into one document, provided each section begins at the top of the page, the heading for each section is in upper letters not less than 3/16 inch (4.8 mm) high, and each section includes the applicable warnings for that section.|
60.2.1 Clear and complete instructions for the installation of the heater shall be provided. The instructions shall include the following items:
If a heater is intended to be shipped with the legs detached or arranged in other than the intended operating position, clear and complete assembly instructions shall be provided.
If a heater is intended to be shipped with the heating elements not mounted securely in its intended position in accordance with 10.8, the installation instructions shall include clear and complete assembly information.
The operating instructions shall contain all appropriate information needed to operate a heater properly, and shall be preceded by the heading ²OPERATING INSTRUCTIONS,”or the equivalent.
The operating instructions shall:
The instructions for user maintenance shall include explicit instructions for all cleaning and minor servicing – lubrication, external adjustments, and the like – that should be performed by the user; and shall warn the user that all other servicing should be performed by qualified service personnel. User maintenance instructions shall be preceded by the heading ²MAINTENANCE INSTRUCTIONS,” or the equivalent.
|60.5.2||The user maintenance instructions shall indicate when the heater shall be cleaned.|
|60.5.3||The user maintenance instructions, shall state before cleaning, make sure the power has been turned off at the circuit breaker panel and that the heating element of the heater is cool.|
|60.5.4||The user maintenance instructions, as described in 60.5.1, shall not include operations that would require disassembly of the heater to accomplish.|
|60.5.5||The user maintenance instructions, shall state what cleaning instrument should be used to clean the heater.|
