Ceramic broilers are not as durable but the average home cook will not use a broiler enough to wear it out. Wolf and Capital have similar broilers but the Capital is behind glass. If you wait for the Wolf broiler to heat up before placing food under it virtually all fat/debris should incinerate before reaching the broiler. In my experience some splatter does accumulate over time. The Capital has optional motorized rotisserie. You can't place the food on spike after the broiler has fully heated up because you will burn yourself. Ergo glass. It makes it easier to clean. I think the top rack position in the Capital is closer to the broiler than in the Wolf but not 100% sure on that. That makes it more likely to get splatter if you place the rack that high. But easier to clean.

Gary, You seem to come through for many of my questions. Thanks. I have DCS BBQ with infrared rotisserie, which works similarly to Viking infrared broiler. They are slightly different given that they are positioned differently: side versus top. I use them both and love them both for intended purposes! I am lucky in that I have a lot of "good" cooking appliances... hehehe.... I am trying to learn how to best use my new Speed oven.

I wanted to update this thread to give closure if anyone experiences a similar issue and to let everyone know how the manufacturer, Capital responded. After my last post Capital engineers reviewed the video I posted above and asked me to send some photos of the ignitor so they could confirm if it was installed properly as they suspected it was too far from the broiler. The photos confirmed it was installed correctly. I suspect they received a similar complaint from another customer based on a conversation with their customer support, but can't confirm this. Anyway, they designed a new bracket for the ignitor that held it closer to the broiler and sent it to the service company for installation. The service company installed in in December and this new bracket has fixed the issue. The broiler now ignites within 1 or 2 seconds of the gas valve opening. It took Capital a few weeks to come up with a solution, but they were responsive right from the first time I called and I think the time they took was reasonable to figure out what was wrong, why it was occurring, and how to fix it (including testing in their factory). Overall the range has been working well and we are happy with the purchase.

I do have to share one additional experience with the IR broiler. I once broiled some salmon and left it in just a little too long and it looked burnt. The marinade/cure for the fish did have a fair amount of sugar in it, but was wiped off before hitting the broiler. I took a nibble of the crust and it didn't taste burnt so I served it, because the rest of the fish was really moist. Afterwards, my wife commented that the best part of the fish was that "burnt" crust. I had to agree because that crust was like eating a toasted fish "cracker" or "chip." I didn't use a dry rub, so that crust was all fish.
