ABSTRACT:
A heated air circulator adapted to be placed against a radiant-type heating stove. The housing of the circulator, which defines a chamber therewithin, includes upright back and side walls which are unjoined along their adjacent upper edge portions. A plurality of spaced-apart, transverse fold lines on the back and side walls, where the same are unjoined, permit portions of these walls to be folded over to form a chamber top at a height conforming to the height of the stove. The circulator includes a damper regulated by a temperature-responsive spring whereby flow of unheated air into the chamber increases as the temperature within the chamber increases.
