+ | found in the link of the explanation is strongly misleading. Visible radiation ( red to violet ) is 700 to 400 nm. The example spectrum in the middle does not fit to this. Maybe some guesswork here results from that link. After some "metering" with a ruler on the screen my guess for the spike in the fireplace spectum now is ca. 1.5 or 2.1 µm , being the first harmonic of either O-H or CO2 respectively.

:I agree that the color band representing the spectrum of visible light given is not directly related to the (human) visible spectrum in the source (Flame Detection). The visible spectrum ranges from about 770nm to about 395nm, or about one octave.
