Final answer:
In the Gas Code, 'damper' refers to a venting system component that controls and regulates the flow of exhaust gases and ensures proper venting from combustion appliances.
Step-by-step explanation:
The term 'damper' when used in the Gas Code refers to a device that is a component of a venting system. It is used to control and regulate the flow of exhaust gases from combustion appliances to the outside, ensuring safe and proper venting. A damper may adjust to allow more or less gas to pass through, but its primary function is not to adjust the gas flow for combustion purposes.
A damper is not a pressure regulator, an emergency shut-off valve, or a device to adjust gas flow as those devices serve different functions within a gas distribution system. A pressure regulator controls the pressure of the gas, an emergency shut-off valve stops the flow of gas during an emergency, and a device to adjust gas flow would typically be a valve used for controlling the supply for combustion or appliance use.
