    Abstract - (Show below) - (Hide below)

    Describes the requirements and test methods for the construction, safety, classification and marking of non-domestic gas-fired overhead radiant tube heaters incorporated into a multi-burner system (called system D and referred to in the body of the text as the "system") with each burner unit under the control of an automatic burner control system.
