An electrically operated vent damper on a mid-efficiency furnace typically opens when the furnace is ignited and requires venting of combustion gases. The damper is controlled by the furnace's control board, which activates it once the ignition sequence is complete and the blower is running. Once the furnace cycle is complete and the appliance shuts down, the damper will close to prevent heat loss and ensure safety.

What is the purpose of a furnace damper and how does it affect the efficiency of a heating system?

The purpose of a furnace damper is to control the flow of air and heat in a heating system. By adjusting the damper, the amount of heat that is released into the home can be regulated. This can help improve the efficiency of the heating system by ensuring that the right amount of heat is being distributed, reducing energy waste and improving overall performance.


How damper helps wood furnace?

A damper in a wood furnace controls the airflow within the system, allowing for better regulation of combustion. By adjusting the damper, users can increase or decrease the amount of air entering the furnace, which helps optimize the burning of wood for efficient heat production. This control not only enhances the furnace's efficiency but also reduces smoke emissions and improves overall safety by preventing excessive heat buildup. Proper damper management ultimately leads to more consistent heating and fuel conservation.

Should the furnace damper be open or closed in winter to ensure efficient heating?

The furnace damper should be open in winter to ensure efficient heating.


How do you know whether a furnace damper is open or closed?

There should be a lever somewhere on the duct near the furnace. If it is open, the lever will be parallel to the duct. If the damper is closed, it will be perpendicular to the duct.


What can cause a humming noise in the attic when the furnace is on?

If the furnace itself is in the attic, the humming is likely caused by electrical components in the furnace--most likely, the blower motor, or else a transformer or relay coil. If the furnace is located elsewhere, the humming may be caused by a damper motor or possibly the air movement itself vibrating a damper or some sheet metal.The HVAC Veteran


What controls an oil furnace draft?

An oil furnace draft is primarily controlled by the flue damper and the chimney design. The flue damper regulates the airflow by opening or closing based on the furnace's operational needs, while the chimney height and design create the necessary draft to exhaust combustion gases effectively. Additionally, the pressure inside the furnace and outside atmospheric conditions can also influence the draft. Proper draft is essential for efficient combustion and to prevent the buildup of harmful gases.


What is the purpose of a Damper in an HVAC System?

A damper in an HVAC system regulates airflow within the ductwork, controlling the volume and direction of air reaching different spaces. It can be manually or automatically operated to balance temperatures, enhance energy efficiency, and maintain comfort levels throughout a building. By adjusting the airflow, dampers also help prevent overloading the system and improve overall performance.


What is a Louvre damper?

A Louvre damper is a flu-gas flow control device, analogous to a Venetian blind, that fits between a furnace's flu gas outlet and its chimney; operation of an external lever causes the slats to rotate up to 90 degrees in unison as the damper moves from fully opened to fully closed and visa versa.


When is the placing of a manually operated damper permitted in a vent connector?

The placement of a manually operated damper in a vent connector is permitted when it is installed in a manner that does not obstruct the flow of combustion gases and complies with local codes and regulations. It should be located in an accessible area for operation and maintenance. Additionally, the damper must be designed to prevent backdraft and ensure proper venting of the appliance it serves. Always consult the manufacturer's instructions and local building codes for specific requirements.


Why use barometric damper on wood furnace?

A Barometric Damper when used properly will help regulate the draft. This in return will allow for better combustion, longer burns and less fuel to be used. One problem with a Barometric Damper is the chimney will run a little cooler due to the introduction of room air. If the unit isn't being burned correctly, this can cause creosote to accumulate in the chimney. The Barometric Damper and flue must be checked periodically and cleaned when necessary.


What is damper in a boiler?

A damper in a boiler is a device that regulates air flow into the combustion chamber. It helps control the amount of oxygen available for combustion, thereby maintaining the desired temperature and efficiency of the boiler. By adjusting the damper, the operator can fine-tune the combustion process for optimal performance.
