I think that would be fine since you won't have that strong flame hitting the steal directly.
My boiler has a high temp steel combustion tunnel which works fine cause the Varm doesn't have an intense gasification flame like many boilers. This also means I don't have any experience with ceramic combustion tunnels so take my opinion with that in mind.
Good luck,
Noah

mine did that once and I took some refractory cement and glued the old piece back on and propped it up with an old wrench I didn't need until I got the new ones. If you cant rig the old piece back on and your going to still run it. might be a good idea to turn the fan speed all the way down.
I can't quite tell what I'm looking at but if you're concerned about the steel being in the bulls eye of the flame you could drop a couple fire bricks in there.
Ditto on propping a couple firebrick in there.
I wouldn't take a chance on it myself otherwise. Buying a few days worth of fuel is not worth the problem that flame impinging directly on the steel can cause. It can be burned through faster than you'd think.
What happens is that the steel can get so hot (under certain flow circumstances) that even if water backed, a bubble can form in that area leaving the steel unprotected. You can easily demonstrate this for your self by watching air bubble form on the bottom of a pan of water on your stove. The air bubble can tend to stay in the hot spot and basically create a void where there is no water. When that happens it would only take a few burn cycles for the flame to torch its way through.
