Abstract
The unit restores existing, masonry fireplaces without entailing dismantling of the latter. A heating jacket base, heating jacket, smoke chamber and flue lining are set into the existing firebox, smoke chamber and flue. Ducting is provided to move heating air through the heating jacket, and ducting is provided to pass combustion gases into the smoke chamber and flue. Internal air, or outside air, is accommodated in the unit for heating and combustion. Blowers are provided to move the heating air into the fireplace site (room) and/or to draw in outside air simply to exchange interior, stale air.
