I recently upgraded from a 28” griddle to a new 36”. I like it overall, but it doesn’t seem to get as hot as I expected.
The flames on all burners look consistent and mostly blue (with a small light-blue column, very little yellow), but they’re noticeably smaller than my old 28”. In ~40°F weather, after 10–15 minutes on high, the surface temp only reaches about 300–400°F. My 28” would hit 550+ in that same time.
I replaced the regulator thinking it was faulty. With the new regulator and temps in the low 60s, it eventually reached ~500–550°F after 15–20 minutes, which was enough to season. Today, cooking again in the low 40s, the hottest spot only reached ~450°F with all burners on high.
