So ask this AHJ where he would like you to place this non-code compliant
sprinkler in this space.I still think your best bet is to place it in
the corner,that way you cover the most floor space (1/2 of
2.222----REALLY???)and get enough water bouncing around this spce till
it finds the fire. :)
And BTW,be sure to keep the head a minimum of 4" off the wall ..... oh
yea,you only HAVE 4".

I agree. This was a "what do I do?" call from a client this afternoon.
He was going to try to meet with the AHJ, but he was the one who had
written it up as being obstructed. Someone at the Convention asked me
where I find these people. Directly or indirectly, they find me.

Blow up the HVAC unit?, just ;)
Locate the head with deflector at bottom of the 16" deep
obstruction. Show
the section where head can be located up to 22" for obstructed
construction.

It may be hard for him to shove the HVAC unit against the wall.
With
the minimal space allowed in this closet he still needs room to
make
duct connections, electrical connections, drain connections etc.
But
hey you could ask.

Todd,
This is just a thought.Get the HVAC contractor to shift the unit
into
the corner,then place the sprinkler in the opposite,leaving 8"
clear on
2 sides.You can maintain the 4" min. off the wall and cover ALL the
clear space in the room.Right?

Todd,
If this is residential, 6.8.1.5.3.1 specifically addresses this
concern.

Subject: Mechanical closet obstruction
I know this was referenced in another post, but I can't find it
so
I'm starting a new thread.
A 2' x 2' mechanical closet. The unit is mounted on the floor and
a
16" x 16" plenum comes off the top and runs up through the
ceiling
at roughly the center of the room (approximately 4" clearance on
each side). One sidewall sprinkler is installed near the ceiling
and the AHJ questions the head being obstructed. Outside of
installing 4 sprinklers in the closet, any good way to address
this? The State Building Code specifically excludes the
application of
common sense.
Thoughts?
