Draft Scope/Description:

This Standard applies to newly produced Type 1 clothes dryers (see Clause 3), hereinafter referred to as dryers, constructed entirely of new, unused parts and materials

a) for use with natural gas;

b) for use with manufactured gas;

c) for use with mixed gas;

d) for use with propane gas; and

e) for use with liquefied petroleum (LP) gas-air mixtures.

 

This standard applies to dryers for installation in buildings including manufactured homes and park model trailers.

 

Rationale: Subclauses a) to e) identify types of gas that may be used to fuel clothes dryers addressed in this standard. Subclause (f) identifies a particular type of building where the clothes dryers may be installed.

Subclause f) is unnecessary as currently provided. Other standards that identify in Clause 1.1 types of buildings where the appliance may be installed do so only to limit the gases that may be used to fuel those appliances.

The standard does not include any requirements specific to appliances for installation in recreational vehicles. A statement is needed to identify where dryers complying with ANSI Z21.5.1  CSA 7.1 are or a not permitted to be installed.

The construction of clothes dryers for use with the above mentioned gases is covered under Clause 4.

The performance of clothes dryers for use with the above mentioned gases is covered under Clause 5.

1.2

Clauses 7 and 8 include coverage for electrical equipment, wiring, and accessories built in or supplied for use with the dryer.

1.3

Clause 7 contains provisions that are unique to the United States.

1.4

Clause 8 contains provisions that are unique to Canada.

1.5

Special construction provisions applicable to a dryer designed for use with an optional listed conversion kit are outlined under Annex A.

1.6

All references to “psi” throughout this Standard are to be considered gauge pressures unless otherwise specified.

1.7

Clause 2 contains a list of standards specifically referenced in this Standard and sources from which they may be obtained. Clause 2 includes the U.S. and Canadian reference standards where applicable.

It is the responsibility of the user of this Standard to determine which referenced standard applies, based on the requirements of the Authority Having Jurisdiction at the location of the installation.

1.8

Special construction provisions applicable to a clothes dryer designed for use with an optional listed conversion kit are outlined under Annex A. Also see Clause 4.22.13.

1.10

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
