Ask your dealer for the correct probe.Should I ever see the flame shield in front of the cat glowing orange? The shield itself was glowing (as well as the cat). I had it ripping full throttle for a bit when it happened. Stove top hit 700F.
On another note I'm still not sure what the correct cat probe length is for the Sirocco with the convection deck. My cat probe has been useless since I added the deck (raises it about 1-1/2"-2" out of stove). I can engage halfway through the inactive range.
Yes, the shield will glow on occasion, no harm.
