I have been asked to remedy an inspection violation. The state inspector left a notice that stated:

ASME violation; "boilers,pressure vessels" no locking electrical disconnect.

Now the only electric running to this boiler (located in a church) which is a new installation, is for the low water cutoff as far as I can tell. Where would I install a locking disconnect? I'm lost !!!
 
This boiler has more to it than a LW cutoff. Depending on fuel type you will have blowers, ignitors and elect. fuel solenoids. The LW cutoff is just one of the safety devises on a boiler. If the boiler is feed from a breaker you may be able to install a breaker lockout to satisfy the inspector.
 
U might need to state with a label, multiple means of power disconnect(s) also...

I do not think this would be correct. The boiler would have only one main disconnecting means. The boilers I deal with are in the 400hp rating they have their on distribution panels mounted to the units. It distributes power and has overcurrent protection for the blowers, pumps and control circ. for all the relays and contacts associated with all the safety devises. The distribution panels are feed from a single disconnecting shunt breaker with E- stops mounted by the exit door. This breaker is in an enclosure that has lock out bars made on to the case. The inspector made us install the shunts with the E-stops by the exit door since we have two of these boilers sitting side by side running. We have now renamed the E-stops as the oh s*** buttons:grin:

The ones I have installed are usually warrick high level/low level/low shutoff stops boiler so it doesnt self destruct and or alarms of problem . direct vent have sail switchesfor both fan proof and combustion air pressure on larger units

Yes, the boiler does have two pumps in the system as well. So I would put a disconnect between the panel breakers and the boiler equip. it'self to satisfy the locking disconnect issue ? Thanks
p.s-Anyone have a diagram to represent this install? Thanks again

How many feeds did you run to the boiler ? That is how many disconnects you need. It may be easier for us if you showed the diagram of how it is wired since we have not seen it and you have :smile:

Some other contractor did the initial install, I have been asked to clean up the errors. I know there are two circuits, one for each pump, and then another one for the l.V. stuff, i.e cutoff swithces, etc.
