Boiler Room Shutdown
Boiler Room Shutdown
(OP)
I have been the HVAC controls industry for over 13 years and have seen some plans and specifications that require the following:
A manual means at the boiler room entrance to shutdown all gas fired boilers.
Could anyone direct me to appropriate Code or Standard that requires this? Is this a International building Code, NFPA or local code.
I am aware of refrigerant room shutdown thru a refrigerant monitor.
Thanks for your advice!

RE: Boiler Room Shutdown
1. A manually operated emergency shutoff switch or circuit breaker must be located just outside the boiler room door and marked for easy identification. Consideration should be given to the type and location of the switch to safeguard
against tampering. If the boiler room door is on the building exterior, the switch must be located just inside the door. If there is more than one door to the boiler
room, there must be a switch located at each door.
2. The emergency switch or circuit breaker must disconnect all power to the burner controls.
3. This requirement is limited to single and modular boilers exceeding 400,000 Btu/hr input installed after January 1, 2006.

Perhaps you could cite the specific code section in NFPA 85...I'd like to read it.

I did find this blurb in Kibart Inc. Consulting Engineers Newsletter:
I do not have a copy of of this ASME section to confirm though.
But I'm still thinking I've seen it documented somewhere else too....

IMC governs where I am; don't know where you are.
RE: Boiler Room Shutdown
WoW!! I wouldn't be able to determine I needed an emergency shutdown switch at the exterior door from that.
The IMC 2003 Commentary states:
No mention of this being an Emergency Shutdown is made.
I still think I've seen it somewhere else in a more user friendly verbiage - may be in my state's (Georgia) Boiler Safety Code....But can't find that either...

It's good to know the codes and standards behind the plans and specifications that we work from. The present project we are working on is more of a design build project.
I think on the present project we will go ahead and add this boiler emergency stop switch to cover ourselves.

"A manually operated remote shutdown switch or circuit breaker shall be located just outside the boiler room door and marked for easy identification. Consideration should be given to type and location of the switch to safeguard against tampering. If the boiler room door is on the exterior, the switch should be located just inside the door. If there is more than one door to the boiler room, there should be a switch located at each door. The switch must shutdown all power to the burner controls......and so on. Very long section.
