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.
