Impact, Overview, Fees and Action Required

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requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date of October 3, 2016 unless the product is found to comply with new/revised requirements.

Overview of Changes: Revised or added construction 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:

  • February 1, 2016 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
  • April 1, 2016 = 6 Month Quote Cut-off – Quotes returned for necessary re-evaluations
  • September 2, 2016 = 30 Day Warning – Client advised of all non-compliant Reports to be Suspended
  • October 3, 2016 = Effective Date – ATM Suspended for all non-compliant Reports
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 – Please immediately identify any current Listing Reports or products that are no longer active and should be removed from our records.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.

 
Description of New/Revised Technical Requirements
ClauseVerdictComment
4.10.2 Portable or stationary appliances for connection to a fixed gas piping system by means of a gas hose connector shall have a connector that complies with the standard for Gas Hose Connectors for Portable Outdoor Gas-Fired Appliances, ANSI Z21.54 • CSA 8.4.
4.11.14 The gas pressure in any refillable LP-gas cylinder shall not increase by more than 50 psi (344.7 kPa) when the appliance is operated as specified in Clause 5.15, Wall, floor, and ceiling temperatures, and for a period of 30 minutes after the end of the test. All cylinders shall be filled to rated capacity. The pressure relief valve shall not activate to discharge test gas.
4.11.15 If an appliance is equipped for use with more than one cylinder, in accordance with Clause 1.2b)v), no leakage is permitted from either connection when one is connected to a cylinder and the other is not connected.
4.11.16 Appliances designed for the installation of 2 propane gas cylinders, in accordance with Clause 1.2b)iii) or Clause 1.2b)vi), shall have a manifold installed that shall not allow gas to flow to the appliance unless the valves of both cylinders are in the open position and gas is flowing from both cylinders simultaneously.
4.18.4(q)(ii) For appliances complying with Clauses 5.20.4 and 5.20.5, a diagram with dimensions showing the manufacturer’s recommended position of the appliance, its supply cylinder and hose routing shall be included. At a minimum, the diagram shall be in a WARNING format including a warning about a tipping hazard.
4.18.4(r) For appliances designed to be fueled by two 20 lb (9.1 kg) cylinders, a statement that the appliance is designed for the installation of two 20 lb (9.1 kg) cylinders and will not operate unless the valves of both cylinders are open and the appliance is drawing fuel from both cylinders simultaneously.
4.19.2 The appliance shall bear the following information on a Class III marking affixed to the principal (main) assembly of the appliance and shall be attached or printed in a location where it can be easily observed or is accessible for observation when the appliance is installed as it would be in service.
a) The manufacturer’s or distributor’s name and address.
b) The manufacturer's or distributor's model number of the appliance.
c) A distinctive number that will identify an individual appliance.
d) For appliances for fixed fuel piping system and equipped with an appliance gas pressure regulator,
the normal manifold pressure in inches water column.
e) For appliances for use with a fixed fuel piping system and equipped with an appliance gas pressure regulator, the minimum permissible gas supply pressure for purpose of input adjustment.
f) Type of gas for which equipped: “Natural or Propane.”
g) The statement “For Outdoor Use Only. If Stored Indoors, Detach and Leave Cylinder Outdoors.” The marking for an appliance for connection to a fixed fuel piping system need only display the first sentence of this statement.
h) If the appliance utilizes any electrical equipment, the voltage, frequency (Hz), and total current input in amperes. If the total current input of all components is less than 12 amperes, the input marking may optionally be shown as “Less than _____* amperes.”
* This amperage rating shall be equal to or greater than the total input in amperes.
i) Identification of this requirement as follows:
“ANS Z21.97–(year) • CSA 2.41-(year), Outdoor Decorative Gas Appliances”.
j) Symbol of the testing agency.

5.13 Dual cylinder manifold
A manifold for appliances designed to be fueled by two 20 lb (9.1 kg) cylinders shall have inlet ports for the connection of gas supply lines from two propane gas cylinders and a single outlet connection port. The manifold assembly shall be designed so that there will be no flow of gas from its outlet unless a cylinder containing gas is connected to both inlet connections and both cylinder valves are opened.
