CSA Group's 2019 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 valve train is a manifold of components and piping that supplies fuel and air to a burner. Gas technicians/fitters must be familiar with:
• components that make up main fuel trains, air supply trains, and pilot air/fuel trains;
• burners; and
• how to install and maintain burners and gas trains so that gas-fired appliances operate safely and with maximum fuel efficiency.
Gas technicians/fitters are also frequently called on to convert gas appliances from one fuel to another, which involves changes to the valve train and burner.
