Yeah, it must need a little moisture still in the mortar to cure with heat. But if they assemble a stove at the factory with cemented seams, it could sit around for a lot more than 30 days before it gets fired up, so I don't know?? I wouldn't try to speed it up with a blowtorch....too easy to over-do it and get porosity in the cement. I would just let it dry for 3 weeks and then burn a real low fire (just a few small kindling sticks added at a time.) Fireplace mortar, furnace cement, stove/gasket sealer are all sodium silicate-based and should be pretty similar. The stove sealer had a bit runnier consistency.I believe it says "Fireplace Mortar" on it. I am Positive it said to Not let it air dry for more than 30 days.....need everything to be perfect with this new stove, the wife was getting pissed that she had to get up every 4hrs to fill the old one.
