Ok so I am going a little farther back in time with this post. I wanted to go electric and wished I could afford 3 blichmann kettles... but not being independently wealthy I could not. (Let me say I am not hating on anyone that has blichmann kettles I am just jealous...lol)
So I scoured Amazon and found some King Cooker kettles (15 gallon) and they had 2 listed that were "used like new" so i rolled the dice and bought them. To my surprise the were simply new!! 2 fifteen gallon kettles for under $200 was a steal in my opinion. They were slightly thin walled for my taste, but I was not going to direct fire them so what the heck.
Here they are with some hardware from Bobby in NJ store aka BrewerHardware.com. I have 2 kettles with sight glasses and 5/8 dip tubes.
Fast forward from these photos on to the installation of elements and herms coil....
Sight glass was installed already. Hole drilled for element installation.
The elements I am using are 5500 watt ULWD, here I am removing the stock rubber washer from the element.
The outdoor boxes I used have some stand off nubs that have to be filed off before installing the back plate or it will not sit flush.
Drilling a hole in the back plate, using the opening drilled in the box for approximate location.
Element fits perfectly!
The back plate is held on by screws and JB weld
Back plate installed, now to install the element...
(you do have to drill and tap the outdoor box to accept the back plate and screws)
Some installation goodies from Mcmaster Carr (love that place!!)
Washer and o-ring ready for installation.
Heating element installed, the o-ring sandwiches between the back plate and the outside of the kettle. The stainless washer prevents the o-ring from squeezing out.
