Brian,
Sorry,
I don't see it that way. It does not say that this only applies to
obstructions up to 9-in wide or your up a creek.
What it does say is that if you are 36-in away that is all the further you
need be.
Contact me by phone to discuss this. I am in the office.

Jeff,
Basically the 4 times rule is only good for obstructions up o 9" wide
then,
why not just make 36" the number and be done with it?

Brian,
NFPA 13, 2007 8.8.5.2.1.3 states..."the maximum clear distance required
(for
extended coverage UR/Pendent heads) shall be 36-in......"
What needs to be clarified?
This already is clarified from previous editions.
I think it's pretty clear.
36-in. is the MAXIMUM, regardless of the actual 4 times dimension.

Jeff,
That's the confusing part, how can 36" work when the book also says it
needs to be 96"? I think some clarifying in the next release may be in
order.

Brian,
I believe it should be read to mean that the most/furthest away you
have to be is a maximum of 36-in. The 36-in. is the maximum limit.
Without this provision, you would instead need to be 4 times away or
96-in.

Subject: Sprinkler Pattern Obstructions
Forum,
I know I must be reading this wrong but as usual I am in a hurry and
could use some help. NFPA-13 (2007) 8.8.5.2.1.3 states that the
sprinkler shall be positioned a minimum of 4 times the maximum
dimension of the obstruction, but then it goes on to say a maximum of
36" clear space. In my case I have a 24" column I'm trying to avoid
which by the 4 times rule would get me 8'
away, how does the max. 36" clear come into play? Also look at Figure
8.8.5.2.1.3, I'm so confused ........
