Q. How is a double connection automatic oiler attached?
A. First, the steam pipe must be drilled and tapped above the throttle
with ½ or ¾ inch gas tap, as may be necessary to receive the oil
discharge pipe of oiler and put oiler in place. Then tap the steam pipe
about 18 inches if possible above the top of the condensing chamber and
fit in a ¼ inch gas pipe for steam connecting tube, which attaches to
the top of condensing chamber. (See illustration.)

Where the steam pipe cannot be tapped 18 inches above the condensing
chamber, it may be tapped lower down and the steam connecting tube
of required length be bent in a horizontal coil. With the single
connection oiler it is only necessary to drill and tap one hole in the
steam pipe.

Q. Should oiler become clogged, how can it be cleaned?
A. Open the valves, by which steam can be forced through it, and all
the passages will be cleaned. This can be done without stopping the
engine.
Q. If oiler is not in use and in danger of freezing, what should be
done?
A. Leave valves D, G and E open, and all water will be drained off.
Q. If the glass tube in oiler should get broken, what should be done?
A. Shut valves D and E, remove broken glass and replace with new.
Q. How can oil be prevented from sticking to lubricator glasses?
A. A very simple remedy is to fill the glass with glycerine and let the
oil feed through it.
