CHAPTER I. 

 FITTING UP AND STARTING A NEW ENGINE, 



N packing an engine for shipment it is usual 

 to remove the brass fittings to prevent their 

 being stolen. These, together with the hose, 

 governor belt and wrenches are packed in a 

 box. The rod for the flue scraper (and the 

 straw fork, for straw burning boiler), are 

 placed in the boiler tubes and the funnel for 

 filling the boiler is placed in the smoke-box. The fire-box, 

 ash-pan, tubes and smoke-box should be examined to insure 

 the removal of all loose parts before the fire is started. 



Attaching Brass Fittings. In attaching the fittings to the 

 boiler, care should be taken to screw them in tightly enough 

 to prevent leaking. Brass expands more with heat than 

 iron, therefore where a brass fitting screws into iron, the 

 joint will be tighter when hot than when cold : consequently 

 should there be a leakage it should be stopped by screwing 

 the fitting in a little further when cold. In screwing a pipe 

 into a valve or other fitting, the wrench should be used on 

 the end of the valve into which the pipe is being screwed. 

 When the wrench is put on the opposite end, the valve is sub- 

 jected to a twisting strain that is very liable to distort and 

 nun it. The Wow-off valve and other valves about the engine
