Vacuum systems

I have a question regarding vacuum levels for a given system.
Is there a formula or some kind of standard for a given vacuum?
Example : I have a job site with 2 large cleaver Brooks boilers whose associated vacuum system is running at 29" ( inches)
Is this normal? To much?
How do I know?
What level ought it be?
Is this current level likely to cause a problem?

vacuum questions
while you are waiting for a response from the sages of steam here, you could do a search here for "vacuum", and it will probably give you some links in the library, and other threads.
is this 1-pipe, or 2-pipe heating?
vacuum systems are a favorite topic, so you will probably get quite a bit of interest!--nbc0 -
29 inches is practically
a perfect vacuum, too high for any but deep variable vacuum systems. That system should heat up very, very quickly. Variable vacuum systems such as VariVac operate between 6 and 25 inches normally, the higher vacuum during warmer weather produces cooler steam, in the range of 140 degrees. Cool.
A typical constant vacuum system such as I have seen will operate at between 6 and 10 inches Hg.
However, if you can maintain 29 inches, dang, that is a tight system, good test."If you do not know the answer, say, "I do not know the answer", and you will be correct!"
