4.1.5 The stove shall be of such construction as to be secure against displacement, distortion, warping, or other damage, and shall be supported to maintain a fixed relationship between essential parts under normal and reasonable conditions of handling and usage so as to determine continued compliance with these provisions. Such parts not permanently secured shall be designed so that they cannot be readily incorrectly assembled and cannot be improperly located or misaligned in removing or replacing during
use, cleaning, or other servicing.
These requirements also cover appliances equipped with a self- contained butane gas fuel supply. The fuel container is of the non-refillable type and has a maximum capacity of more than 4 fluid ounces (118 ml) but no more than 10 ounces (296 ml) of butane. The maximum capacity in pounds of water is 1.08 Ibs (0.49 kg). A stove may employ no more than two fuel containers. The fuel container is removable and replaceable in normal use. The butane fuel container shall comply with DOT 2P or 2Q requirements and shall be listed to the Standard for Non-refillable (Disposable) Type Metal Container Assemblies for Butane, UL 147B.
A stove for use with propane/butane mixtures shall be tested with the gas specified by the manufacturer. If more than one canister is approved for use, each model number of canister shall be provided by the manufacturer for testing. If more than one gas composition ratio or canister is to be approved for use, each gas composition ratio or canister shall be tested with the appliance at the discretion of the testing agency.
A combustion hood, provided with adjustable legs, shall be placed on the appliance so that the combustion hood covers the utensils placed over all of the burners. When a single hood will not cover all burners, more than one combustion hood may be used. With the edge of the combustion hood(s) located at least 5 in (127 mm) above the cooking surface, the flames shall be observed.The hood(s) shall then be lowered in small increments, preferable 1/2 in (12.7), while a constant observation of the flames is maintained. As soon as any noticeable change in the character of the flame occurs, the hood(s) shall be raised 1/2 in (12.7 mm). With the hood(s) at this height a sample of the flue gases shall be secured from the outlet of the hood(s) and analyzed for carbon dioxide.The outlet area of the hood(s) may be gradually reduced to obtain as high a carbon dioxide percentage as possible without altering the flame characteristics.CSA 11.2 pdf download.
