Preface
This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of vented gas-fired space heating appliances. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on vented gas-fired space heating appliances designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to help reduce such risks while retaining the normal operation of the appliance.
1.1 Scope
1.1.1
This standard applies to newly produced vented gas-fired space heating appliances (see Part XII, 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:
a. For use with natural gas;
b. For use with manufactured gas;
c. For use with mixed gas;
d. For use with liquefied petroleum gases (propane) (also see 2.2e); and
e. For use with LP gas-air mixtures.
The construction of vented gas-fired space heating appliances for use with the above-mentioned gases is covered under Part I.
The performance of vented gas-fired space heating appliances for use with the above-mentioned gases is covered under Part II.
1.1.2
This standard applies only to the following appliance types, as defined in Part XII, 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.
1.1.3
This standard covers the 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 Exhibit B, Items Unique to Canada.
1.1.4
If a value for measurement as given in this standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.
1.1.5
All references to psi throughout this standard are to be considered gage pressures unless otherwise specified.
1.1.6
All vented gas-fired space heating appliances shall conform with the applicable requirements under Part I and Part II. In addition, for requirements specific to product type also see:
a. Vented Room Heaters - Construction, Part III Vented Room Heaters - Performance, Part IV;
b. Gravity and Fan Type Direct Vent Wall Furnaces - Construction, Part V Gravity and Fan Type Direct Vent Wall Furnaces - Performance, Part VI;
c. Gravity and Fan Type Wall Furnaces - Construction, Part VII Gravity and Fan Type Wall Furnaces - Performance, Part VIII; and
d. Gravity and Fan Type Floor Furnaces - Construction, Part IX Gravity and Fan Type Floor Furnaces - Performance, Part X.
1.1.7
Exhibit A, Items Unique to the United States, contains provisions that are unique to the United States.
1.1.8
Exhibit B, Items Unique to Canada, contains provisions that are unique to Canada.
1.1.9
Special construction provisions applicable to vented space heating appliances designed for use with an optional design-certified conversion kit are outlined under Exhibit J, (Optional) Provisions for Listed Gas Appliance Conversion Kits.
