If there are combustibles then you would most likely need one at the top as well here. Years ago the Fire and Elevator inspectors fought it out and came up with a monitored valve (like a butterball va) on each as a "compromise". You can run them exposed with no box but you will have to drop the valve down to 4'-0" AFF and loop back up and into machine room/pit/top.

If the pipe is exposed at about 7'6" AFF would a box still be required? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mark Jason Sent: Wednesday, February 22, 2012 3:09 PM To: [email protected] Subject: RE: Elevators - Michigan rules Yes, a monitored control valve is required in Michigan. Location of valve and box is also important. Usually if you stand 6'-0" in front of elevator door and rotate or spin 360 degrees you should be able to locate it. If its location is not visible from there they must have signage pointing you in the right direction. Of course, it's all on what the AHJ will approve for location. I haven't put a head at the top of the shaft in years but you will need one in the pit and machine room. In some places you can eliminate the head in the pit if it is an electric elevator in a non-com shaft with no hydraulics.

Do these need to be provided with a shutoff valve/s?
