Hi everyone,
The gas-valve solenoid failed on my 500G North roaster for a second time, and Mill City has wisely changed vendors to a new part. The new valve is about 1/2" shorter than the original so some piping changes are required.

Anyone out there installed a valve, and had to find or make short lengths of threaded black iron pipe?
I will need to lengthen the incoming section of pipe that connects to the new valve, OR cut an oval in the roaster case and shift the incoming gas pipe over 1/2" to meet the new valve. I don't presently have equipment to thread iron pipe or experience buying a pre-made threaded stub.
Advice and council is requested.



Present failed gas valve above (Solenoid removed)




Replacement valve is shorter.

Home Depot or most any plumbing shop will cut you a piece of black pipe any length you want or will likely have the already cut to length.

It looks like the ell goes into a reducer using a very short threaded extension, in the green box here:

You just need one a little longer. Your local big box will have them, usually in one inch increments.

Sorry you are having this issue. Did MCR not have any ideas for you? Now I see the prior post. How hard was it to open this up?

Bill, Thanks for the tip. I can check the local HoDe and order an assortment of threaded stubs. The new valve is 1/2" pipe and it looks like the two ells are either 3/8" or also 1/2".

I wondered if other MCR 500G owners have replaced this valve and how much gas plumbing is actually needed. MCR shipped out the replacement valve in 24-hours. They emailed me today and asked for more pix of the connections to the gas-gauge and supply-line to the burners. It may be possible to tweak the valve location and minimize refit of sealed connections.
I haven't removed the old valve yet, still gathering plumbing tips and trying to minimize resealing of gas joints.
