CSA ANSI Z21.1a-2011 American National Standard For Household Cooking Gas Appliances. Part II: Performance 2.1 General Room temperature, when specified, shall be determined by means of 3 temperature indicating devices accurate to within ± 1°F (± 0.5°C) and located 5 ft (1.52 m) above floor level, and positioned with respect to the appliance under test as shown in Figure 6, Location of Temperature Indicating Devices for Determination of Ambient Room Temperature During Test for Wall, Floor and Enclosure Temperatures. The observed room temperatures shall be the average of the temperatures indicated by the temperature indicating devices. 2.1.9 Room temperature, when specified, shall be determined by means of 3 temperature indicating devices accurate to within ± 1°F (± 0.5°C) and located 5 ft (1.52 m) above floor level, and positioned with respect to the appliance under test as shown in Figure 6, Location of Temperature Indicating Devices for Determination of Ambient Room Temperature During Test for Wall, Floor and Enclosure Temperatures. The observed room temperatures shall be the average of the temperatures indicated by the temperature indicating devices. 2.4 Combustion 2.4.1 An appliance shall not produce a concentration of carbon monoxide in excess of 0.08 percent in an air-free sample of the flue gases when the appliance is tested in a room having approximately a normal oxygen supply. During combustion tests of a built-in unit all cracks related to installation (other than designed air openings) shall be sealed. For ranges or cooktops intended for use in conjunction with a ventilation system with provisions to direct air in a downward direction: Combustion testing shall be performed on any enclosed compartment (oven or broiler), specialty top section burners which operate automatically such as thermostatically controlled griddles, open top broilers, or any other burner hidden from view of the operator. After the burners have been in operation for 5 minutes under Test Conditions 2 and 3 in Table X, Gas Pressure and Input Conditions for Use in the Various Performance Tests, samples of the flues gases shall be procured and analyzed for CO and CO2. During these tests no test pots shall be placed on the open top burners and no 75 percent coverage plate shall be used over the open top broiler. For ranges incorporating a pyrolytic self clean feature and intended for use in conjunction with a ventilation system with provisions to direct air in a downward direction, an additional series of...
