SEAL TIGHT Chimney Dampers are made for use only with open woodburning masonry fireplace chimneys and are NOT suitable for use in the following types of 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.
