VThis will result in their cores Aand 4=5being drawn up, permitting gas to flow up throughthe 5 pipe 36 through the valve-body 39 and-the burner nozzle 40. ythe saine time the` valve 13 will be turnedV from its normal horizontal; position, across the pipe 5 to the `vertical position shown in Fig. l2 so as to loper'mit-a flow of airthrough the pipey 9 up- "Aivard through the tube 5 4of the -middle section, around the nozzle 40 Linto thefmixing chamber. .f Y i The'gas burner is formed of arectangular 15.-'cap k50 'corrugated transversely to the radiya'tor, as shoivnin Fig. l. The upper'portions of these corrugations'are formed With narrow" slits '52 through which the mixed 'airfand gas can pass.
