CSA Group's 2020 Gas Trade materials reference the Red Seal Program's trade outlines for your preparation to become a nationally recognized gasfitter. Please visit the Red Seal Program's website for more details.Â
Overview:
A thorough understanding of hydronic heating system operation, servicing, and maintenance is an important part of a gas technician’s/fitter’s training in order to install and maintain a gas-fired boiler.
Be aware that connections to gas appliances that include potable, hydronic, refrigerant, duct work, and electrical connections that exceed the essential components affecting the safe operation of the appliance, though potentially not mentioned within the Gas Code, must meet local provincial and municipal code requirements and may fall outside of the scope of practice of a gas technician/fitter. It is the responsibility of the gas technician/fitter to comply with all codes as well as their local trade regulations.
