Blackfoot, Id
I have a Masterbuilt 2 door dual fuel smoker, that I've been struggling with. Ever since the weather got warmer I can not keep my temps low. I would watch the temp climb over 300*, usually stopping around 310*.After searching the forum and reading idea, after idea, I went ahead and ordered a needle valve to put in the propane line. Turns out I also needded a few more fittings than just the valve. I believe Dirtsailor has or knows of a kit that might be easier.


And I have got to say, if your worried that it won't make that big of a difference, I am now able to stabilize my smoker at 180* for twenty minutes.


The 180* is the bottom prob and the 172* is the upper. Since the smoker was stabilized I didn't feel the need to go longer than 20 minutes.

I'm sure at that temp of 180* I will have problems with blow out, but the difference is huge!
If your having the same problem, give it a try. With all the parts it was about $30, well worth it!
 
I too built a shelve under the burner to hold the AMNPS. I have to do some tweaking on mine as there doesn't seem to be the right amount of draft pulling into the upper chamber. I believe if I was to put a stack on it (like I want to anyway) it would work how I want it to.
 
Hey cmayna. Can you post a pick of how you placed your amnps? I am getting one soon and would like to see some placement options.
 
Here ya go.......

Sorry it took me a lil bit to get back with you, I just went to my local gas store and told them what I was doing and they hooked me up. If you would like I can take it apart this weekend, take some pics and narrow it down to what you need. Hopefully you'll be up smokin by Sunday!

I would recommend that you take your LPG hose with you so they have both thread types. Nothing sucks worse than being all excited to hook it back up then realizing someone goofed! Good luck!

I'm interested in doing this for better control on low temps. I just have a question. What is the difference between this valve and the one they sell on the Lowes website with the regulator assembly?

Do you need one or both parts to work?
 
Some have got that one to work but I couldn't the thing is way to touchy any tiny adjustment make a big difference in the flame. Mine would etheir blow out the flame or it would be screaming or the flame would go up and down.

There's this one too. It looks like it comes already with the hose assembly and the part the OP had.
I am interested in this for two things: better temp control at a lower setting and also eliminating the use of using the knob that comes with the smoker, there's too much playing it and I would like to fine-tune.

That's why I was wondering if the small valve the OP had is good enough just by itself.
 
Was able to get mine set up today with the same needle valve you got and so far works like a charm Mike. Up and smokin now !

Hey xray xray sorry it took me awhile but it looks like you got er figured out, work alright?
Congrats stevo8 stevo8 ! Remember to watch for blow out, had it happen a few times. If your using a thermometer like the maverick et-733 you'll know pretty quick. So what's for dinner?

I haven't actually bought anything yet. Temp control isn't an issue for me. Once the weather gets cooler, I will purchase the needle valve with the regulator assembly. It looks like the hose is longer than the stock one on the MB XL40 s

Baby backs are on the menu for tonight!
