Preface

This is the sixth edition of ANSI Z21.86/CSA 2.32, Vented Gas-Fired Space Heating Appliances. It supersedes the previous editions published in 2008, 2004, 2000, and 1998.

Scope

1.1
This Standard applies to newly produced vented gas-fired space heating appliances (see Clause 3, Definitions), hereinafter referred to as appliance(s), constructed entirely of new, unused parts and materials, and having input ratings up to and including 400,000 Btu/hr (117 228 W).

These appliances are for use with:

a) natural gas;

b) manufactured gas;

c) mixed gas;

d) propane gas [also see Clause 5.2(e)]; and

e) LP gas-air mixtures.

The construction of vented gas-fired space heating appliances for use with the above-mentioned gases is covered in Clause 4.

The performance of vented gas-fired space heating appliances for use with the above-mentioned gases is covered in Clause 5.

1.2
This Standard applies only to the following appliance types, as defined in Clause 3, Definitions:

a) gravity vented wall furnace;

b) fan-type vented wall furnace;

c) fan-type vented wall furnace with cooling unit;

d) vented room heater;

e) gravity direct vent wall furnace;

f) fan-type direct vent wall furnace; and

g) floor furnace.

1.3
This Standard covers thermal efficiency and related markings of only those appliances whose efficiencies are not regulated in the U.S.A. by the Energy Policy and Conservation Act of 1975 and the National Energy Conservation Policy Act of 1978,* or covered in Canada by Clause 18, Items unique to Canada.

* At the time of this printing, the above acts regulate the thermal efficiency (heating capacity) of vented appliances. For information, contact the U.S. Department of Energy, Conservation and Solar Applications, Consumer Products Efficiency Branch, 20 Massachusetts Avenue, N.W., Washington, DC 20545.

1.4
If a value of measurement as shown in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.

1.5
All references to psi throughout this Standard are to be considered gauge pressures unless otherwise specified.

1.6
All vented gas-fired space heating appliances conform to the applicable requirements under Clauses 4 and 5. In addition, for requirements specific to product type also see:

a) Clause 6, Vented room heaters construction, Clause 7, Vented room heaters performance;

b) Clause 8, Gravity and fan-type direct vent wall furnaces construction, Clause 9, Gravity and fan-type direct vent wall furnaces performance;

c) Clause 10, Gravity and fan-type wall furnaces construction, Clause 11, Gravity and fan-type wall furnaces performance;

d) Clause 12, Gravity and fan-type floor furnaces construction (United States only), Clause 13, Gravity and fan-type floor furnaces performance (United States only); and

e) Clause 14, Vented condensing gas-fired space heating appliances construction, Clause 15, Vented condensing gas-fired space heating appliances performance.

1.7
Clause 17, Items unique to the United States, contains clauses that are unique to the United States.

1.8
Clause 18, Items unique to Canada, contains clauses that are unique to Canada.

1.9
Special construction clauses applicable to vented space heating appliances designed for use with an optional design-certified conversion kit are outlined under Annex H, Provisions for listed gas appliance conversion kits (optional).

1.10
Clause 2 contains a list of standards specifically referenced in this Standard, and sources from which these referenced standards may be obtained.

1.11
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 (nonmandatory) to define their application.
