Final answer:
A flue damper should only be used with solid fuel-burning appliances because it helps to prevent heat loss through the chimney and controls draft. For gas-fired appliances, dampers are not recommended as they can interfere with the necessary air mixture and create unsafe conditions.
Step-by-step explanation:
A flue damper should be used only with a solid fuel-burning appliance, and not with a gas-fired appliance. Flue dampers are designed to help control the draft in a chimney. When using solid fuel-burning appliances like a wood stove, it is crucial to have an efficient damper to prevent heat loss through the chimney.
With gas-fired appliances, dampers aren't recommended because gas combustion relies on a precise mixture of gas and air; flue dampers can restrict airflow and lead to unsafe conditions. Therefore, a flue damper is most appropriately paired with solid fuels that do not require the same level of air mix precision as gas appliances.
A solid fuel-burning appliance such as a wood stove produces smoke and other byproducts that need to be vented through a chimney.
A damper is a device used to control the flow of air and gases in a chimney. However, when it comes to choosing the right type of damper, it's important to take into consideration the type of fuel being burned. A backdraft damper should only be used with a solid fuel-burning appliance and not with a gas-fired appliance.
