Survey: Indirect High Heat on Your Grill?

Indirect high heat…sort of.
Burners 6 and smoker on to cook the turkey legs more,
and also using the rotisserie burner…

Here is how I suggest setting up a gas grill for indirect high heat:

For my Weber Summit, I preheat the grill for 15 minutes with all the burners on high, then I turn off the middle burners (leaving burners 1 and 6 lit and on high heat). I want an internal temperature of 450*F, or higher if I can get it.

Reader Roy G has the same Weber Summit that I do, and he had some questions after making my  Grilled  Butterflied Chicken with Dry Brine. His grill was only 375F with burners #1 and 6 set to high – closer to what I would call medium heat. I was surprised by this; I use indirect high heat on my gas grill all the time. I was sure my temperatures were higher.

Except…my indirect cooking usually includes the rotisserie burner. Or, if I’m not using the rotisserie, I have some of the other burners on to cook a side dish.

I went out and tested my grill. Sure enough, Roy was right. Two burners on high left me with an internal temperature of 350F. If I turned the rotisserie burner on, I was right where I expected to be, at 450F.

After this test, I turn on my smoker burner to get a little extra power when I want indirect high heat on the Summit.

My next test was at my parent’s house, with my dad’s Weber Genesis. It only has three burners, but each burner is longer than the burners on my Summit. It turns out the longer burner matters – when I set the Genesis up for indirect high heat, with the two outer burners on and the middle burner off, the temperature was just shy of 500F. This range of temps made me wonder – what about other grills? Are there a standard set of instructions I can use in my recipes, or is it every grill for itself?

The survey:

When a recipe says “set your grill up for indirect high heat”, what do you do? And, what temperature do you get? Please answer the following questions:

I’ll keep the survey open for a week, and summarize the results for everyone later this month. Feel free to pass the survey on to anyone you think would know the answers – the more responses I get, the better the results will be.

Thank you for satisfying my curiosity!

  1. I’m reader Roy G and I really appreciate you doing this survey.  Eager to see the results!

  2. Don’t forget that there are other factors at play not having to do with the burners. During a Texas winter I will have to have my S620 burners 1 and 6 on high, and burners 2 and 5 on low to keep 400*. During the Summer, burners 1& 6 on med-hi for the same temp. I have also heard, but cannot confirm, that LP will burn hotter than NG, also affecting temps. 

  3. You’re right about the weather affecting the temps – we have the same issue up here in Ohio during the winter. I felt like the survey had too many questions already, so I left that one out…

    You’re also right about LP and NG – LP does burn hotter. According to the following site, burning a cubic foot of NG generates 1000 BTUs of energy; burning a cubic foot of LP generates 2500 BTUs:

    But…that doesn’t mean a LP grill is necessarily hotter than a NG grill. Grill companies compensate by building NG grills with larger pipes. This delivers more gas to the grill, so the BTU ratings are the same between their LP and NG models. So, if the NG grill is designed properly, it should generate the same amount of heat.
