n tank.

53. Q. In the event of the heater pipes or connections becoming
defective, how could the oil be heated in tank?

A. By closing the firing valve, closing the valve on heater pipe, and
opening valve on heater box, the steam from heater throttle can be
passed directly through the oil feed pipe to the fuel supply.

54. Q. In the event of an objectionable quantity of water in oil, how
can it be removed?

A. In some instances the tanks are provided with drain pipes for this
purpose, but in the absence of same, the feed hose or pipe between
engine and tank can be disconnected and used as a drain to fuel oil
tank.

55. Q. What effect has leaks between fuel tank and firing valve?

A. A waste of oil only.

56. Q. What effect has leaks between firing valve and burner?

A. In addition to a loss of oil while fire is burning low, and but
little steam atomizer being used, it interferes very materially with
the engine's steaming by admitting air when using considerable steam
atomizer. This causes a very irregular oil feed.

57. Q. What action of the fire would indicate leaks in pipes between
firing valve and burner?

A. The fire-box will give off sounds similar to slight explosions, and
the smoke at stack will indicate irregular fuel feeding.

58. Q. What would you consider the proper adjustment of burner?

A. That which will provide for the delivery of the oil from burner to
flash wall without striking arch, side walls, or floor brick while doing
so.

59. Q. In case it becomes necessary to fire up an oil burning engine
with wood, what parts should be given particular attention?

A. The brick work. To see that same is not damaged or displaced while
placing the wood in fire-box, also to protect by placing brick over that
portion of burner extending into fire-box ahead of mud ring, or by so
arranging the wood in fire-box as to prevent any great amount of heat
from reaching the burner and melting nozzle of same.

60. Q. In case of sudden drop in steam pressure, what might be the
cause?

A. Loose brick perhaps fallen in front of burner and obstructed the flow
of oil. The petticoat pipe may be loose and out of line or the dampers
may have fallen shut.

61. Q. In case brick have fallen in front of burner, how can they be
removed?

A. By a hook provided for that purpose. They can usually be forced out
through the vent openings, but if this cannot be done, they should be
thrown against the blast wall in order t
