GMG Daniel Boone Dialed in...sorta

[AZRedneck]

I added a second top rack to the GMG Daniel Boone today. I just ran some temp tests with the MAV ET-732 thermometer and adjusted temp on the grill with the wifi app. I was able to get the center of the top rack dialed in at 235F with very little deviation, however the left and right sides were both 217-219. The temps are steady in all three zones.

I bought a 13lb Prime Packer Brisket from Costco today at $2.89 a pound. I am going to cook it this weekend and will be sure to post pics no matter the outcome. I am concerned about the temp differences though. The point is gotta be on one side or the other, so should I just go with it how it is or should I try to adjust the heat shield at the bottom to make it a bit warmer on one side for the point end?

That's not a really big temp swing from one side or the other. I use an offset quite a bit and cooking with sticks has a lot more temp swing in it...and the end product is always good. Just make sure you pay attention to how it looks and how the bark is forming and if you need to adjust then be ready to face the brisket in one direction or the other. EASY!!

[AZRedneck]

Thanks, but this being my first brisket I'm still skeered. I'm cooking the thing no matter what so we'll see how it goes.

[BBQCentralShow]

Don't be scared...worst that happens is you eat some really good beef that you can cook better next time. Also, brisket & eggs with the leftovers...or brisket nachos...or brisket stuffed ABT's...the list goes on!! Brisket is a mostly "feel" thing not just a temperature thing.

I've cooked two packer briskets on my Daniel Boone, both with excellent results. These are the only briskets I've ever cooked. Both were cooked fat side down, one with point end in center of girl, and the other withe the flat end in the center. Didn't seem to make any difference. I do recommend using a crutch when the brisket reaches about 160 degrees F. To cover your bases, you might swap ends on the brisket after you apply the crutch.

Here's an account of my experience:

Nice looking cook Chas Martel! I think I'm going to load it up with the point as close to center as possible. I'm gonna inject and skip the crutch for my first run. Two different guys at work smoke briskets all the time, one of them has a GMG Jim Bowie and they never crutch. Their briskets are delicious. It's getting trimmed now (after this post) and dry brine for about 24 hours or so, them smoke time.

Sounds like a good plan. Keep us posted!

I just got a GMG DB and, found the overall temps to be 10-20 degrees less at grate level compared to the GMG readout. I also notice the left side seems seems to be hotter than the right side. Anyone else notice this?

Le Grill,

Most Pellet Grills are setup and operate as Convention Ovens.

The Pellets in Firepot create the heat, the fans turn it.

Heated air is Higher Pressure RACING to get to Cool Lower Pressure outside the chimney, therefore the Chimney Side is hotter. I have a fix for that

1: I found using a MAV 732 remote thermometer that the cook grate temp in the center is consistently 30-60 degrees lower than the grill setting. Of course your grill may be different.

2: When I first set mine up, the right side was hotter than the left. Remove the drip trays, and move the heat shield a little to the left in your case. I found the happy medium for temp differences left to right was when I set the heat shield about 1 inch from as far right as it will go. Hope this helps!

AZRedneck,

Do you have the new 1-piece Stainless Steel Heat Shield?

I have a procedure for you to align it properly.

Let me know

[Mitchl]

dgodke I have the one piece heat shield and would be interested in your alignment procedure. Have temp differences from side to side and have been moving meat around to compensate. Could you please share your procedure you mention. Thanks. Mitch.

[AZRedneck]

dgodke My DB has the 1 piece heat shield.

[Le Grill]

I found I was able to control the heat difference by moving the heat shield left or right. Moving left makes it hotter on the right and vise versa. Using my ET-733 I'd say I got it pretty dialed in! This was with the DB set to 225. I then used the temp offset feature to make the GMG match my Maverick.

AZ RedNeck have you noticed the difference in styles of the GMG racks? It looks like they have fabricated two different styles where the legs are different. Do two racks fit front to back in the DB and you can close the lid??

Just got a Camp Chef SmokePro, and found the same thing. I thought there was something wrong with the controller. Looks like it is normal for pellet grills. Thanks!

[AZRedneck]

Chogers I'm not sure what rack you're referring to. My GMG had no problems with the lid closing.


​​I do not own my GMG anymore. There was a problem with black soot on my food. I now know for sure it was the pellets not burning properly rather than a problem with the grill itself.

[Chogers]

Ive been getting two different answers and I am guessing its because of two different versions of the top rack. Here is the link to what GMG sells on their website...https://greenmountaingrills.com/prod...lf-upper-rack/

And then there is this one that is supposedly the new version. It is what my dealer sells and what amazon sells here...https://www.amazon.com/Green-Mountai...mg+upper+shelf

I think the new version (the 2nd one listed) fits two front to back and the lid can be closed. The other one is too tall I'm assuming from the answers I have been getting from Amazon. Wondered if anyone else can weigh in on this subject?

Im partially thinking of saying screw it and just get this JERKY RACK... https://www.amazon.com/gp/product/B0...=ATVPDKIKX0DER


AZRedneck I have used only GMG pellets and Pit Boss pellets. GMG pellets I have had no problem but Pit Boss pellets from Menards were making some crazy creaking sound in my auger assembly so I said to hell with those cheap things! Not gonna risk it! But anyways Im loving my Daniel Boone! Kicking meats ass and taking names! LMAO!

I have the second one for my Jim Bowie model, but I only got one shelf. I could probably fit two in side-by-side. You could stack them, but it would have to be thin pieces of meat on the racks, I’d guess.
