Read these threads. ‘Nuff said. Get a backguard.

If the oven vents out the backguard, even the 6"er might discolor your backsplash--quartz is a bit delicate in that regard. If it's not too late and there's space, add 6" of counter behind your range.

Without a backguard, this is what happens to Quartz near a heat source.

I have seen some of these quartz horror stories but the trim part I am confused about. Some of the trim or riser seems to just vent up and maybe protects against the burners but just redirects the heat from oven. Do any wolf or bluestar guard or riser or whatever they name it protect the backsplash if we stick with quartz?

A tall backguard blows heat to the front. We have not heard on this forum of anyone having issues with Quartz and a tall backguard (rather than a short or medium- height one) as far as I know, though I can’t guaranty it. Frankly, I think it’s a better look to have a stainless steel panel that meets the hood. It’s less choppy, and more pro. Not sure if it’s your taste, but it’s a suggestion as an alternative to a backguard, and to scorched Quartz.

And a stainless steel sheet from stove to hood is not a solution unless the entire wall in that area is not combustible in any sense. This means steel studs and no sheetrock . The stove installation instructions should provide proper direction, as well as being compliant to the International Residential Code. The tall risers are intended to avoid the need for a non-combustible wall.

This is a confusing set of recommendations. Obviously these ranges don’t all sit in front of SS backsplashes which appeals to a limited aesthetic regardless of the functionality.
Any actual owners out there with quartz slab backsplashes and pro style ranges able to chime in? Do you all have charred surfaces??

Could you do a pro-style range top and wall ovens instead of a full range?

IMO no home needs a 48” range and NO quartz behind any range. The venting alone will be a fortune and the noise is horrible with it. I run a catering biz with a 36” 6 burner rang and have never found a need for more. A pro range needs a pro type backspalsh which is stainless in any commercial kitchen for a reason. JUst because you see a picture of something does not make it right to do.

I think needs and wants are an entirely different philosophical discussion.

I just want to reconcile the implication here that having a range and quartz backsplash is somehow incompatible and doomed for failure vs any user/real world experience to support or negate that.

Is it a highly likely or theoretically possible scenario of causing actual quartz damage?

I would think that the photos Shannon posted would be adequate proof of real world experience. But I guess that depends on one's definition of "doomed for failure".

Obviously these ranges don’t all sit in front of SS backsplashes which appeals to a limited aesthetic regardless of the functionality.

I have a 48" Bluestar with a SS backsplash. It's not my aesthetic -- I would have preferred blue and white tiles, all things being equal -- but in my kitchen function trumps form every time, especially when it comes to safety and minimizing cleaning and maintenance.

“any user/real world experience to support or negate that”

Gee, I posted 3 pics and linked 3 comprehensive threads on the topic with posts from “users” with “real world experience”. So, what you are really looking for is “I want people to tell me this is fine”. If you read the linked posts, you’ll see mention that even the Quartz manufacturers won’t say that. Their warranties exclude damage from installation near a heat source.

Here are some screenshots from Cambria’s website, but the other Quartz manufacturers say same.

Though, I think this still won’t be enough for you.

We have a 48" blue star with a 6" backsplash and it just redirects the heat to the front of the stove, i.e it is not a mechanical thing, just deflects the heat. I originally ordered it without a backsplash but thought better of it after doing more reading on what needed to be done to make the wall truly non combustable, including those 3 links @Shannon_WI mentioned. We have regular subway tile for the backsplash, so cannot comment on the quartz slab. Personally, I would lose sleep putting a slab behind a range with no back guard.

Thank you for addressing my question re actual use of backsplash/guard and redirecting heat. The 3 links above appear to pose risk of scorching backsplash with island trim which would not be my plan. That being said, it seems the BS backguard redirects the heat while the Wolf risers simply vent up 5 or 10", which sounds less helpful to me.

Any Wolf range users out there and backsplash/riser experiences?

What matters to the Authority Having Jurisdiction is code compliance. If you have no code enforcement, and don't care about why there are rules or can do all the required analyses pertinent to safety yourself, then do whatever you want. Otherwise, there is Section 308 of the IMC, which includes the table below. Risers available from range manufacturers are intended to comply with this table.

Maybe I am not asking the right question here but the intention was not to avoid riser or backguard all together. The question is whether these are actually protective whether 5 or 7 or 10 inches high against a quartz backsplash.
Short of installing SS tall thing with shelf, do any of these risers work or quartz is to be avoided no matter what?
