BC codes on LWCO?

[JRG]

Hello
The unit being installed, Navien NHB-55 has a LWCO installed internally.
Is there one required outside as well.
Thanks

I believe BC uses the same B149.1-15 Code as Ontario.

The Navien NHB-55 is equipped with a pressure-sensing LWCO, so I believe you would require an external LWCO, as per Clause 7.1.13, if components were located below the boiler.

Thanks for the input.
Can't go wrong by installing one.
