If your engine is
running and doing no work, use your injector and stop the pump, for,
while the engine is running light, the small amount of exhaust steam is
not sufficient to heat the water and the pressure will be reduced
rapidly. You will understand, therefore, that the injector is intended
principally for an emergency rather than for general use. It should
always be kept in order, for, should the pump refuse to work, you have
only to start your injector and use it until such time as you can remedy
the trouble.
We have now explained how you get your water supply. You understand that
you must have water first and then fire. Be sure that you have the
water supply first.
THE BLOWER
The blower is an appliance for creating artificial draught and consists
of a small pipe leading from some point above the water line into the
smoke stack, directly over the tubes, and should extend to the center of
stack and terminate with a nozzle pointing directly to top and center of
stack; this pipe is fitted with a globe valve. When it is required to
rush your fire, you can do so by opening this globe and allowing the
steam to escape into the stack.
