    I've got a facility that is remodeling there kitchen and they are wanting to relocate a 2" -2 psi gas line. The existing line as it sits has a 2" ansul system safety gas valve mounted in a horizontal line. If the ansul system goes into alarm it shuts off all the gas to the kitchen. They are wanting to relocate this safety valve and mount it on a vertical line and also if possible mount it above the drop ceiling. I'm struggling to find any good information on the valve itself or code pertaining to it's needed location.
    So my question is can Ansul safety valves be mounted horizontal or vertical orientation?
    Can they be mounted above a drop ceiling or do they have to be visible, easily accessible in the vicinity they serve?

    Thanks

    I don’t know the answer for sure, but I know I’ve seen them installed in a vertical pipe, right or wrong.

    Same here. Ask the fire safety company what they want

    seen them mounted vertical and horizontal
    makes no difference to the valve because its a wire that trips them
    but never ever seen them mounted above the ceiling.

    the ahj GENERALLY wants them visible from the ground. I don't have a current copy of nicet code but would bet it feels the same way. my .02.....its a solenoid, mount where practical with visual indication of position visible from in front of the hood.

    What extinguishing agent do they use now? When I left the plant Halon was to be phased out in the electrical control room.

    Your question about the position of the valve is very noble. I ran across that position problem with some steam traps also.

    I have seen them above drop ceilings. I didn't care much for the idea but it was already there and that wasn't my concern at the time.
