CSA ANSI Z21.84-2012 Standard for Manually lighted, natural gas, decorative gas appliances for installation in solid-fuel burning fireplaces.
Part II: Performance
2.1 General
2.1.1
This standard covers manually lighted, natural gas decorative gas appliances for installation in solid-fuel burning fireplaces for use with natural gas.
2.1.2
When a thermocouple is specified for the measurement of air, flue or vent gas temperatures, a thermocouple or an equivalent temperature measuring device complying with the Performance Test Codes, Supplement an Instruments and Apparatus, Part 3, Temperature Measurement, ANSI/ASME PTC 19.3, shall be used.
2.1.3
Manually lighted, natural gas decorative gas appliances for installation in solid-fuel burning fireplaces are designed for installation only in a solid-fuel burning fireplace. Their designs may take many forms, so for their testing, principles must be established for the guidance of the testing agency which will assure compliance with basic standards for safe operation and acceptable performance, without restricting their design to preconceived forms. With this in mind, the principles stated within Part II are to be used by the testing agency in determining the acceptability of decorative appliances for installation in solid-fuel burning fireplaces.
2.1.4
Gas appliance pressure regulator vent limiters shall be in place during all performance tests.
2.1.5
Room temperature, when specified, shall be determined by means of four 24 AWG (0.20 mm2) iron-constantan bead-type thermocouples, the junctions of which are shielded from radiation. These thermocouple Junctions shall be located so room air temperature can be measured at points approximately 24 in (610 mm) away from the approximate midpoints of each of the four sides of the appliance or test enclosure. The thermocouple leads shall be connected to a recording potentiometer, and room temperature shall be the average of the four individual temperature readings.
2.1.6
All performance tests shall be conducted with all nonpositively secured components other than burner media, in the most critical position.
2.1.7
All performance tests shall be conducted with the appliance in a fireplace test enclosure as shown in Figure
1, Simulated Fireplace Test Enclosure or, as provided by the manufacturer, and with the manufacturer’s
minimum width opening specified in 1 .15.le.CSA ANSI Z21.84 pdf download.
