Abstract
This invention is directed to a heat circulating fireplace arranged and constructed to control the temperature in which air is delivered to an insert module and to control the temperature of the heated air discharged into the fireplace room and/or adjacent rooms. The fireplace includes an air control assembly operably coupled to an insert module which is adapted to be mounted into an existing fireplace or may be part of the original fireplace assembly. The air control assembly including damper means is associated with the fan means and is capable of proportioning outside air and/or room air into the insert module so as to maintain a predetermined temperature of heated air being discharged. The damper means is operable to control or proportion room air and/or outside air to maintain a desired temperature gradient between air to be heated and discharged air to the fireplace room and/or adjacent rooms. Air inlet ducts and heated air outlet ducts are coupled in fluid communication to the insert module. Fan means are adapted to be mounted in fluid communication with the air inlet ducts for conducting air to be heated through the insert module in heat exchange relation with the heat exch…
