signalinc (2406H) installation manual wrong?

Hi there cooconers
 
I just purchased a signalinc (2406H), and looking at the installation manual.  From what I understand from the drawing, I must use 2 circuits on the same bus bar in the power panel.
 
however, step 16 states that I should use 2 different legs, which seems to go contrary of the drawing.
 
I always tought that for bridging the signal, I had to indeed effectively bridge the 2 sides, so step 16 is right, but why keep a wrong drawing then?
 
Who's right, and who's wrong???? 
 
please help me before I burn down my house!
 
for the manual:

Thanks in advance for all help and pointers you can provide,

The manual and drawing are both correct. Legs alternate on a side of the panel. So two adjacent breakers on the same side of the panel are on two different legs. That is how you can get 220 for something like a dryer. Two adjacent breaker slots, two different legs.

There maybe a circuit map on the breaker box. It would also show the connection layout.
Two half sized breakers next to each other. Maybe be on the same line.

Measure between the two circuit breakers you think you are going to use with a multi-meter (on AC voltage mode) and see if you get 220 volts.

Soory for not comming back sooner, but with the crazy weekend, I had to hold hand of my wife in the shopping center.  Not that I'm romantic, If I dont, she start running everywhere spending my HA money
 
On that funny start:
@Weunch: you just teach my something new!  I never ever even tought that it worked that way, never had to, I guess.  Thanks for that.
 
I went and bouth a dual breaker unit, dropped it, all so sure of me.  Plug the Signalinc, and... and nothing.  Felt depressed for a few seconds, then opened a can, felt better
 
 
@BLH: I looked at the back of the cover panel, and there it was, the circuit map you were telling me about.
 
And here is the catch:  it's not alternate lugs, it's alternate *PAIR* of lugs!  (for the record, I got a "Federal Pionner" Panel.)
 
Each *pair* of lugs are isolated by some kind of plastic separator, and I had to slip the dual breaker unit over this separator to make it one lug on each side and then cover both legs.  The dual unit has a slot between the individual breaker, so it's an easy fit once you know you have to do it that way.
 
I would send some pictures, but I cant, for the life of me, find the way to upload them.
 
Anyway, it's now working as expected, the X10 signals goes from A to B, wife will be happy, WAF will go up, good ending.
 
Thanks to all the responders.  It's the sum of your answers that brought light (no pun indended) into that problem.

Mine is an old Federal breaker box in my house.
Only a few breakers next to each other are on the other line. I think it is four or six on the same line before the one below it starts the other line.
