The fan, located in the basement and drawing air from the heater, discharges it vertically upward into a short flue or standpipe which extends into the room above. At a height of about ten feet from the floor the air is distributed horizontally in all directions through short pipes as shown in the drawing. Located in the centre of a space to be heated, this system minimizes the cost of installation, as considerable galvanized iron piping and special duct construction, necessary in other arrangements, are eliminated.
