What is a typical electrical connection for a gas range? correct answers 120 V 60 HZ, two-wire with a ground. What must a flex connector be connected to? What else must be there? correct answers Must be connected to rigid pipe with a shut off valve immediately upstream of the connector. What types of appliances must use a flexible metal connector? correct answers Appliances that vibrate, expand and contract or other movements that could damage a rigid connection. What is the maximum length of a flexible metal connector? correct answers 6 ft Types of gas ranges correct answers Free-standing, built-in and dual fuel Types of heat transfer correct answers Convection, conduction and radiation How does convection work? correct answers Transfer of heat is by heat currents. What are two different types of convection an oven uses. correct answers Natural convection (warm air rises and cool air descends) and Forced convection (heat produced by the burner is circulated evenly with a fan) How does conduction work? correct answers Transfer of heat through direct contact. Particle to particle How does radiant heating work? correct answers Heat rays emitted from a heat source. Localized heating. Two different types of Top burner ignitors. correct answers Standing pilot and Electric ignitor How does the Standing pilot work on a top burner ignitor? What are the variations of the # of pilots? correct answers A continuously lit pilot that once the control valve calls for gas it will ignite it. Can have one pilot for each burner, one pilot for two burners and one pilot for all four burners What does the flash tube do? correct answers Used in stand pilot systems, once control valve is opened gas flows down tube drawing in combustion air with it. It flows towards the pilot and ignites. A flashback occurs back up to tube consuming all the gas. It ignites the burner and gas no longer is in the tube. If the flash tube does not light the burner but has a standing pilot at the base of the tube what would cause this? correct answers To little air or to much gas.
