RECESSED FLUSH WITH CAR FLOOR FLOOR PLATE CUT AWAY TO SHOW GAS-TIGHT TUBULAR RADIATOR OUTLET UNDER FLOOR VALVE OPERATING LEVER FLEXIBLE STEEL TUBING VALVE EXHAUST PIPE TO MUFFLER Illustrating Type A Installation Construction of Perfection Heaters THE thoroughly practical construction of Perfection Motor Car Heaters absolutely assures the perfect heating of motor cars without any gas fumes whatsoever coming in contact with the air breathed or interfering in any way with the ventilation of closed cars. As an example of the thoroughness with which Perfection Motor Car Heaters are made there are 103 separate and distinct machining operations, many of them to .001 of an inch, on a type A Heater. These do not include stampings, die castings, screw machine parts or assembling work. This is only one of the reasons why Perfection Motor Car Heaters are demanded by those who know values in heaters. Perfection Motor Car Heaters are designed by automotive and heating engineers who realize that a pipe from the exhaust to an opening or plate or ordinary radiator in the car floor does not make an efficient motor car heater. Perfection Motor Car Heaters are the result of seven years' study and development. In Perfection Heaters a specially designed valve is attached to the exhaust pipe forward of the muffler. This valve is operated by a graduated and positive control. The valve deflects a portion of the hot exhaust gas through flexible tubing to the heater radiator. (Continued on page right) Page Five | ||
