Gas Venting Dampers work automatically to allow natural draft during appliance operation while preventing residual appliance heat and conditioned air from escaping during off cycles. It also prevents the infiltration of cold air during down drafts.
How does a vent damper work?
What is the purpose of a vent damper? The idea is to retain the heat in the block during the boiler off cycle and to prevent the chimney from drafting air through the boiler and up the chimney. This raises the AFUE a point or two, and ideally saves the end user in fuel usage and operating cost.
What is a automatic flue damper?
An automatic vent damper not only restricts the flow of heated air up the chimney, but can also reduce the amount of cold outside air leaking in to replace the escaping warm air. It is placed in the flue pipe between the heating unit and the chimney to block the passage of heat after the unit has been shut down.
Is a vent damper necessary?
A vent damper is an automatic devise that shuts off the flue pipe when the burner is not running. A vent damper has no effect on the running efficiency of the appliance. It only saves off-cycle losses of heated air. Therefore, if the appliance is in an unheated space, there is no benefit to a vent damper.
Where is the damper on a gas furnace?
For example, an ash pit damper is located at the base of the furnace (the ash pit) while a smoke pipe damper is located in the stove pipe that connects the furnace to the chimney. A damper at the base of the chimney is known as the check damper.
How do I know if my damper is bad?
Check the registers to see if the airflow has ceased. Adjust the damper to the open position and once again check the registers to see if the airflow has resumed. If you feel airflow when the damper is closed, or no airflow when the damper is open, the damper is most likely bad.
How do I know if my ventilation damper is 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.
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.
Does a gas furnace need a damper?
Gas fired furnaces, boilers and water heaters require a flue that has a good draft in it to get rid of the products of combustion after most of the heat has been removed. A vent damper is an automatic devise that shuts off the flue pipe when the burner is not running.
Where is the flue damper on a fireplace?
A flue damper is usually found just above the fireplace stove, at the base of the flue, but may be located further up the flue. A flue damper needs to be manually operated to open or close, and so there will always be a set of controls located on the flue operate the damper.
What flue gas dampers does Hanwel offer?
In collaboration with Amm-tech, Hanwel offers a wide range of high-end flue gas dampers. We supply butterfly dampers, (multi-)louvre dampers, guillotine dampers, bypass dampers and custom-made dampers for flue gas.
Why choose Honeywell control dampers?
HVAC performance is largely dependent on airflow control and Honeywell dampers are built to support improved airflow and heavy use. Honeywell has long been a leading source for commercial control dampers with products that meet the benchmark AMCA 500D air performance standards.
What is the purpose of a fire damper on a stove?
Reducing the draft up the flue by partially closing off the damper. Helping to control how quickly the fire burns through the fuel. Helping to reduce the amount of heat that is lost up the flue. Helping to put out a fire in a wood burning stove in conjunction with using the stove’s air vents.
