What does damper mean?

A damper is a device that reduces the intensity of vibrations, sound, or movements in a system. It is commonly used in mechanical systems to control oscillations or to smooth out movements.


How much should vent on gas fireplace be open?

When using a vented gas fireplace, the damper should be fully open to allow proper ventilation and ensure that the gases produced by the burning gas escape safely through the chimney. Keeping the damper fully open also helps in preventing backdrafts and promoting efficient burning of the gas.


What does it mean when the Room fills with smoke whenever you burn wood in fireplace?

Something is preventing your fireplace from drawing. The damper may be closed, or partially closed. Your chimney may have a blockage, or you may have prevailing winds that push smoke back down the chimney. If you have air flow problems, such as a vent fan that draws air out of the house, it can cause that. Bottom line- if the damper is open, and the flue is not blocked, you need a good fireplace/chimney specialist to examine what you have.


What causes excessive smoke in house when fireplace is lit?

Excessive smoke in the house when a fireplace is lit could be caused by a blockage in the chimney, poor ventilation, wet or unseasoned wood, or a closed damper. It is important to have the chimney inspected and cleaned regularly and ensure proper ventilation for a safe and effective fire.


What causes a smoky fireplace?

A smoky fireplace can be caused by poor ventilation, insufficient airflow, cold chimney temperature, or a buildup of creosote and debris in the chimney. It can also be due to burning wet or unseasoned wood or a damper that is not fully open. Regular cleaning and maintenance can help prevent a smoky fireplace.

What is difference between damper and shock absorber?

A damper is a component that dissipates oscillations or movements within a system, such as in a suspension system of a vehicle. A shock absorber is a type of damper specifically designed to absorb and dampen impact forces when a vehicle encounters bumps or rough terrain. In other words, a shock absorber is a specific type of damper used in vehicle suspensions to provide a smoother ride.


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.

Difference between photohelic and magnahelic guage?

PHOTOHELIC® Pressure ControlPHOTOHELIC® models combine the MAGNEHELIC®gauge with a precise pressure switch that lets you control low and high gas pressures. Knob controls adjust dual set points, which allow for variable deadband control. These set points contain photocells that actuate DPDT relays when room pressures reach a preset upper or lower limit, and they can be set up to control corrective damper action. As the room pressure changes in response to damper motion, and the indicator returns to the null band, damper motion is halted.
