Yes, I do believe that is them.
Feel free to send me a PM.
Dont get me wrong, they really do work well, but you may be in for an un-welcomed surprise in a few years.
PM sent with some info I will not say online.
This unit is just short of five years old.
Pretty nasty corrosion problem.
The back of the fire box is paper thin, and full of holes/cracks. You could pound a nail through it like a tin can.
I am not sure what actually caused this, but believe it had something to do with rain/snow water leaking through the clean out on the chimney. This may have caused a chemical reaction, but I am not sure.
It sure was a PITA to fix.
