Hi everyone ! I'm new to the forum and new to everything wood stove related , so any help will be really appreciated !
I just got my hearthstone installed , and did 3 small break-in fires. I used a few pieces of kindling following the instructions on the manual. Then I tried a bigger burn (about 3.5 hours) , using kindling again and 3 small pieces of cord wood. I did left the front door open for some minutes , to get the cord wood ignited , but short after that I heard some hissing coming from the top of the stove so I closed the front door and decreased the air flow. Overall I think I didn't reach very high temperatures as the catalyst probe barely entered the active range.
Once I was done I noticed something like blisters inside the firebox , on what I believe to be the refractory cement. Is this a signal of over fire ? Is it damaged ? Or this is somewhat normal ?
Thanks for your time !
