Texas LP Gas Examination Study Guide Questions and Answers
Appliance - Any device that utilizes gas as a fuel or raw material to produce light, heat, power, refrigeration, or air conditioning.
Appliance Regulator - A pressure regulator for controlling pressure to the appliance manifold.
Appliance Shut-off Valve - A valve located in the piping system, used to shut off individual equipment.
BTU - British Thermal Unit; the quantity of heat required to raise the temperature of 1 pound of water by 1 degree F.
Category 1 Vented Appliance - An appliance that operates with a non-
positive vent static pressure ad with a vent gas temperature that avoids
excessive condensate production in the vents.
Category 2 Vented Appliance - An appliance that operates with a non-
positive vent static pressure and with a vent gas temperature that may cause excessive condensate production in the vent.
Category 3 Vented Appliance - An appliance that operates with a positive vent static pressure that avoids excessive condensate production in the vent.
Category 4 Vented Appliance - An appliance that operates with a positive vent static pressure and with a vent gas temperature that may cause excessive condensate production in the vent.
Controls - Devices designated to regulate the gas, air, water, or electrical supply to an appliance. These may be manual or automatic.
Direct Vent Appliances - Appliances that are constructed and installed so that
all air for combustion is derived directly from the outdoors and all flue gases are discharged to the outdoors.
Flue Gases - Products of combustion plus excess air in appliance flues or heat exchangers.
Labeled - Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that
maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner. Leak Check - An operation performed on a complete gas piping system, the connections, appliances, and equipment to verify that the system does not leak.
Listed - Equipment, materials, or services included in a list published by an organization that is acceptable to the authority having jurisdiction and concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation of services, and whose listing states that either the equipment, material, or service meets the appropriate designated standards or has been
tested and found suitable for a specified purpose.
Orifice - The opening in a cap, spud, or other device whereby the flow of gas is limited and through which the gas is discharged to the burner.
Pipe - Rigid conduit of iron, steel, copper, brass, aluminum, or plastic.
Piping System - All piping, valves, and fittings from the outlet of the point
of delivery from the supplier to the outlets of the equipment shutoff valves.
Pressure Test - An operation performed to verify the gastight integrity of gas piping following its installation of modification.
Quick-disconnect Device - A hand-operated device that provides a means for
connecting and disconnecting an appliance or an appliance connector to a gas supply that is equipped with an automatic means to shut off the gas supply when the device is disconnected.
Regulator Vent - The opening in the atmospheric side of the regulator housing permitting the in and out movement of air to compensate for the movement of the regulator diaphragm.
Safety Shutoff Device - A device that will shut off the gas supply to the controlled burners in the event the source of ignition fails. This device can interrupt the flow of gas to main burners only or to pilot and main burners under its supervision.
Type 1 Clothes Dryer - Primarily used in family living environment. May or may not be coin-operated for public use.
Type 2 Clothes Dryer - Used in business with direct intercourse of the function of the public. May or may not be operated by public or hired attendant. May or may not be coin-operated.
