6″ Vertical Boiler- the ID plate
by John
Last task before the boiler inspector. The unique identifier. In my case the VR-18-18 code is stamped on the boiler in a safe location, or engraved onto a plaque which is silver soldered to the boiler shell.
I chose the latter method. And used the opportunity to put my name and date on it.
CNC’d the info onto a brass plate, and bent it into shape, I use V-Carve Pro for engraving jobs.
Then silver soldered it into position. In this case I used a lower temperature silver solder… “StayBrite”, so I did not risk melting the previous joins.

Hi John,
Love the work and follow everything you’ve done so far.
For the benefit of someone new, can you please answer the following!
Where does the code come from?
Do you get it from the inspector or apply for a code before building the boiler?

Hi Graham, First you contact the inspector, then submit the plans. If the inspector approves the plans he assigns the number and it is stamped on the plans. The number must be stamped or soldered onto the work before the final approval of the finished job. John.
