What is the primary function of a burner coupling?

The primary function of a burner coupling is to connect the motor to the burner. This connection allows the motor to drive the burner, enabling it to operate effectively within the heating system. The coupling ensures that the mechanical energy produced by the motor is effectively transmitted to the burner, allowing it to perform the necessary combustion process. Proper functioning of the coupling is essential for the burner to ignite and maintain combustion, directly impacting the efficiency and safety of the heating system.

Other options, while related to the overall operation of the burner, do not accurately describe the specific role of the burner coupling. For instance, energizing the ignition system pertains to initiating combustion but does not involve the mechanical link provided by the coupling. Regulating oil flow and controlling burner temperature are critical aspects of burner operation but fall within different components or systems rather than the burner coupling itself.
