Special note should be made that connections made 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.
