More About Top Damper

The Top Damper is made for use only with open woodburning masonry fireplace chimneys and are NOT suitable for use in these installations:

  • Don’t use on chimneys serving vented gas logs. Vented gas logs require the fireplace damper to be removed completely or fixed to a permanently open position; this is to assure that soot, fumes and carbon monoxide do not enter your home.
  • Use only on vent-free gas logs if approved by the appliance manufacturer and the local authority having jurisdiction. However, we don’t recommend it because the moisture generated from the gas logs could damage the chimney structure.
  • Don’t use on chimneys serving other fuels, wood stoves or other appliances such as inserts, furnaces, etc.


The Top Damper can be installed by homeowners who feel comfortable working on a roof, but U.S. Fireplace Products, Inc. strongly recommends you use the services of a qualified chimney sweep who can also inspect your chimney and provide other valuable home safety services.

The Top Damper may be used on round factory-built chimneys venting a fireplace. An RS Adapter for solid-pack chimney or a RS Adapter for air-cooled chimney is available to make this transition. Note: This may affect the fireplace listing. Check with the fireplace manufacturer before installing the adapter and damper.
