Effective June 1, 2016
Effective Date (see Processing Schedule below): June 1, 2016
Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of June 1, 2016 unless the product is found to comply with new/revised requirements.
Overview of Changes: Various changes in construction, markings, instructions and test requirements. Specific details of new/revised requirements are found in table below.
Processing Schedule: So that production of products bearing Listing Marks will not be interrupted, the following schedule of approximate dates has been established to ensure Listing Reports are found compliant by Effective Date:
Fees: An initial review of Listing Report (s) will be covered by a direct billing project and will be invoiced at not more than $1000 per report.
Client Action Required:
Information - To assist our Intertek Engineer with review of your Certification Reports, please submit technical information in response to the new/revised paragraphs noted in the attached or explain why these new/revised requirements not apply to your product (s).
Current Listings Not Active? – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records. We will do this at no charge as long as Intertek is notified in writing prior to the review of your reports.

|4.9.9||The dryer shall be equipped with either a union that would permit the main burner control manifold to be removed without disconnecting the existing supply line or provided with an instruction to install the dryer using a listed connector in compliance with the Standard for Connectors for Gas Appliances, |
ANSI Z21.24 • CSA 6.10. See Clause 4.21.7(b)(xvii). Unions in appliance piping for use with propane gas or LP gas-air mixtures shall be of the ground-joint type or a flanged joint having packing resistant to the action of such gases.
|4.11.1||A gas appliance pressure regulator that will satisfactorily limit the gas supply pressure shall be provided on a dryer for use with natural, manufactured, or mixed gases or LP gas-air mixtures and may be provided with a dryer for use with propane gas.|
|4.13.2||If the regulator is not equipped with a vent limiter, provisions shall be included for installation of a vent line from the regulator to the outdoors in accordance with the manufacturer's installation instructions [see Clause 4.21.7(b)(xv)].|
A bleed line from a diaphragm type automatic valve shall be vented in such a manner as to provide for burning of bleed gas during normal operation. In the event of diaphragm rupture, the bleed shall not permit the escape of more than 1.0 ft3/hr (7.87 cm3/s) of 0.6 specific gravity at 7.0 in wc pressure (1.74 kPa) for natural, manufactured, or mixed gases or LP gas-air mixtures, and 0.5 ft3/hr (3.93 cm3/s) of 1.53 specific gravity at 11.0 in wc pressure (2.74 kPa) for propane gas.
|4.21.2||Instructions for the proper installation, operation, and maintenance of the dryer may be provided as separate manuals or combined as one manual. Each manual provided shall contain instructions to retain the manual for future reference.|
The installation instructions for appliances that are exhausted to the outdoors shall include the following boxed warning:
|4.21.4||Type I commercial dryers shall include:|
a) installation instructions; and
b) maintenance instructions.
|4.21.5||The front cover or the first page of the manual containing the operating instructions shall bear the following boxed warning. It shall be boxed as shown:|
|5.1.1||This Standard covers Type 1 clothes dryers:|
a) for use with natural gas;
b) for use with manufactured gas;
c) for use with mixed gas;
d) for use with propane gas;
e) for use with LP gas-air mixtures; and
f) for mobile home installation.
In conducting the performance tests specified (5.2 a-g), gases with characteristics approximately as shown in Table 5, shall be used.
|5.3||-||Test pressures and burner adjustments|
|5.3.2||The inlet test pressures specified in Clause 5.3.1 shall be the pressures immediately ahead of all controls. The manifold pressure shall be adjusted to 3.5 in wc (0.87 kPa), or lower if specified by the manufacturer, for natural, manufactured, and mixed gases and LP gas-air mixtures. When a gas appliance pressure regulator is provided for use with propane gas, the manifold pressure shall be as specified by the manufacturer.|
|5.4.2||A dryer shall not produce carbon monoxide in excess of 0.04 percent in an air-free sample of the flue gases when the dryer is tested in a room having approximately a normal oxygen supply.|
|5.13||Load fire containment|
Appliances having a rotating drum or basket shall not ignite cheesecloth located on the outside of the appliance when subjected to the Test.
|5.14||Base fire containment|
Appliances having a rotating drum or basket shall not ignite cheesecloth located on the outside when subjected to the Test.
|5.16||Manifold and control assembly capacity|
The manifold and control assembly of a dryer shall have sufficient flow capacity to provide the manufacturer's specified hourly Btu input rating and manifold pressure when supplied with the gas pressure designated as the minimum permissible for the purpose of input adjustment. For dryers for use with propane gas without a gas appliance pressure regulator, the above determination shall be made with 11 in wc (2.74 kPa) pressure upstream of all controls.
|7||Items unique to the United States|
Note:This Clause contains provisions that are unique to the ANSI Z21.5.1 Standard. This Clause does not form a part of the CSA 7.1 Standard.
|7.3.1||When a flexible service cord is provided to connect the clothes dryer to a line-voltage electrical supply, the instructions shall also include the intent of the warning statement.|
|7.4||Electrical diagram markings|
a) Except when electrical equipment is limited to a simple series circuit, electrical diagrams (see Clause 3, Definitions) on Class IV marking material applicable to all electrical circuits within the dryer shall be supplied with the dryer in each of the following forms:
i) a connection diagram to aid in locating components for field service;
ii) a schematic diagram of the ladder form in addition to the connection diagram and, when necessary for clarification, a cycle chart or printed sequence of switching action accompanying the schematic diagram.
b) Wire coding indicated in the diagrams shall correspond to that actually used on the dryer.
c) Electrical diagrams shall conform to the Standard for Electrical and Electronics Diagrams, ANSI Y14.15. See Annex B for reference to pertinent provisions of ANSI Y14.15.
d) Unidentified graphical symbols used for electrical diagrams shall conform to the Standard for Graphic Symbols for Electrical and Electronics Diagrams (Including Reference Designation Class Designation Letters), ANSI/IEEE 315. See Annex C. Abbreviations for identified items shall be as shown in Annex C.
e) The electrical diagrams specified in (a) above shall be attached to the dryer in a location where they are accessible, preferably from the front or top of the dryer, during servicing of the electrical components. Some means of color, letter, or number coding corresponding to the appliance wiring shall be used in the diagrams to facilitate circuit identification.
