ELEC-1014 - Electricity - Introduction
This introductory course provides a foundation on which electrical troubleshooting techniques can be built. Proficiency in electrical troubleshooting techniques enables technicians to correctly diagnose electrical problems associated with heating, refrigeration, and air conditioning equipment. Combining theory and practical work, this course describes basic electrical theory and concepts, electrical hazards, safe working practices and procedures, electrical testing equipment and applicable Codes.
ELEC-1015 - Basic Electricity
We must understand how electrical power is supplied and accessed, as well as the various methods and devices used to ensure that the electricity is distributed safely. This course describes amperage service, ground fault circuit interrupters (GFCI), electrical bonding to gas piping, single-phase and three-phase power supply, electrical hardware, the types and ratings of fuses and breakers and the types and gauges of wire, as well as thermocouple and powerpile DC millivolt systems. There is considerable focus on appliance wiring and schematic diagram design and interpretation. Utilizing furnace simulation boards and gas-fired furnaces, students will design and draw schematic and wiring diagrams for natural draft, fan assisted and high efficiency furnaces, then wire and troubleshoot operational faults.
HLTH-1014 - Health and Safety
At the completion of this course the student will be thoroughly knowledgeable of hazards and safety procedures that relate to working conditions as well as the safe handling and procedure for materials they will be using. They will also learn skills and practice dealing with customers in various situations.
MACH-1018 - Basic Gas Technician
This course focuses on common fasteners, hand, and power tools used in the HRAC field. This course also looks at the origin and identifies the properties of natural gas and propane, characteristics of complete and incomplete combustion, upper and lower explosive limits, potential sources of ignition and carbon monoxide and other by-products of incomplete combustion. In this course there is a major focus on natural gas and propane installation Codes and Code adoption documents, Ontario regulations, and standards associated with the manufacturing, testing, installation, and servicing of natural gas and propane appliances, components, and equipment.
MACH-1019 - Introduction to Gas Appliances
It is essential for HRAC technicians to reference and interpret information from appliance manufacturer's installation and service manuals, service bulletins, and safety directives. This course familiarizes you with important sections of a gas appliance manufacturer's installation and service manual and looks at the association between the manufacturer's installation instructions and the Natural Gas and Propane Installation Code. Electrical drawings, mechanical drawings, and the purpose of various charts, graphs and tables are studied. The course also covers the operating characteristics, features, and methods of heat transfer of natural gas and propane appliances, explains the purpose of venting gas appliances and the different types of gas venting material.
