CSA CAN1-12.4-M84:2018 pdf download.Dispensing Devices for Propane Fuel for Highway
1.1.1 CSA CAN1-12.4-M84 applies to the mechanical and electrical features of newly manufactured dispensing devices for pro-pane liquid for use as fuel in internal combustion engines where such devices are intended primarily to dispense the liquid directly into the fuel storage tank of the vehicle.
1.1.2 This standard contains SI (Metric] equivalents to the yard/pound quantities, the purpose being to allow the stan-dard to be used in SI (Metric) units. If a value for a measure-ment as given in this Standard is followed by an equivalent value in other units, the first stated is to be regarded as the requirement. The given equivalent may be approximate. If a value for a measurement and and equivalent value in other units are both specified as a quoted marking requirement,the first stated unit, or both units shall be provided.
1.1.3 Installation of a dispensing device shall be in accor dance with CAN1-B149.2 "Installation Code for Propane Burning Appliances and Equipment", and the latest edition of CSA Standard C22.1 "Canadian Electrical Code, Part I," and requirements of the authorities having jurisdiction.
1.6.1 The base is considered to be that part of the assembly intended to be anchored to the foundation on which the dispensing device will be installed. It shall be a metal casting of good quality not less than one quarter inch in thickness or of not less than No. 12 gauge steel or of other materials or constructions reinforced or otherwise stiffened to provide equivalent strength.
1.6.2 The base shall be provided with bolt holes .to accom-modate bolts of not less than one-half inch (12.7 mm) diameter for anchoring the dispenser. At least 2 holes shall be provided if the dispenser is not more than 6 feet (1.83 m) high and at least 4 holes if the dispenser is over 6 feet (1.83 m) high. If two holes are provided, they shall be located on opposite sides of the base and at least 13 inches (0.33 m) apart. If more than 2 holes are provided, they shall be located approximately symmetrically on a bolt circle having a diameter of not less than 13 inches (0.33 m). The bolt holes shall be accessible, e.g. by being located in the base at the sides of the dispenser provided with doors or removable panels.
1.7 HOUSING
1.7.1 The construction of the housing, where provided, shall be such that it will not become warped, bent, loosened, or otherwise damaged in normal operation so as to prevent the device from complying with any of these requirements. Ex-posure of the assembly to the weather shall not interfere with the performance of the operating parts that it encloses.
A recess or depression in the housing that may collect water shall be arranged to direct such collection to the outside or to points within the structure where it can fall to the ground without damage to the internal components.
1.7.2 When the housing totally or partially supports operating parts, the supporting section shall be constructed to provide the necessary rigidity and strength. The housing shall be secured to the base in a manner that will provide substantial support upon removal of access panels.CSA CAN1-12.4-M84 pdf download.
