Do you need a damper on a boiler?
If your home doesn’t have a furnace for heating, it may well have a boiler. Regardless of what type of boiler you have, you could benefit from having a flue damper installed. If your boiler functions by burning fuel, then you need to be sure the fumes from the burned fuel can escape from the home.
What is the use of a damper?
A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control.
Should furnace damper be open or closed?
If you are looking at a duct that is coming off the furnace and going straight up like it is going to the upstairs, and the wing is in the same direction as the duct, it is open. If the wing is in the opposite or vertical position to the ductwork, then the damper is closed.
Why do you need a barometric damper?
A barometric damper is needed to help assist the chimney with proper function. A barometric damper regulates the chimney draft. Over time pressure can build up in the chimney ducts and the barometric damper job is to regulate and release the built-up pressure.
What is a flue damper?
A damper is located in the flue of your chimney. The flue is where the smoke escapes when the fire is going. Dampers are placed inside of the flue to help control ventilation. Your damper should have a chain or handle that you can access in order to open and close it.
What are the 3 types of dampers?
Some of the various types of dampers used in the HVAC system are mentioned below.
- Butterfly Flat Dish Damper. Butterfly dish dampers are mainly designed for high efficiency with less maintenance.
- Blade Dampers.
- Guillotine Dampers.
- Louver Dampers.
- Inlet Vane Dampers.

What’s the difference between damper and dampener?
As nouns the difference between damper and dampener is that damper is something that damps or checks: while dampener is a device that moistens or dampens something.
What are the different types of dampers?
Do all furnaces have a damper?
Small furnaces and larger, industrial sized systems both use dampers. In fact, most modern furnaces contain four dampers. Dampers ensure that furnace systems work well and safely by automatically regulating furnace functions or allowing a person to manually adjust those functions to safe settings.
How do you know if the flue is open or closed?
Before lighting a fire, you can tell if the damper is open by placing your hand into the fireplace. If you feel a draft coming down the chimney, it is a good indicator that the damper is open. If you don’t feel any cold air coming down the chimney, it means that the damper is closed.
What is the use of a damper in a boiler?
You can improve the efficiency of your boiler by installing an in-line vent damper. These are used to automatically shut off the vents to your boiler when they do not need to be open. By shutting off the vents when the boiler is not firing, you can help retain heat inside the house.
What is secondary air work in boiler?
Secondary air enters the boiler below the black liquor injection nozzles and above the primary air. The secondary air assists in shaping the top of the char bed and supplies air to burn the combustible gases that rise from the bed.
What is a blast damper?
Blast Damper with integral grill to shield against flying objects. A blast damper is used to protect occupants and equipment of a structure against overpressures resultant of an explosion. The blast dampers normally protect air inlets and exhaust penetrations in an otherwise hardened structure.
What is a combustion air damper?
Automatic Combustion Air Dampers . Most building codes require that outside air be provided for the ventilation of boiler and furnace rooms. Fixed or manually-operated combustion air dampers can allow cold winter air into the room even when burners are not operating. By installing automatic combustion air dampers, which only open when the burners are operating, exposure of the boiler and piping to cold outside air is reduced.
