How long for Mortar to completely dry?

I've finally finished a fireplace refacing project (turned out great using Eldorado stone!). How long should I wait for the mortar to cure before having a fire? I'm using a wood burning insert which throws a lot of heat and the last thing I want to do is compromise the bonding process and have stones start to fall off. The closest stones are about 10 inches from the top and side of the insert. I've waited a week so far.

Also, does anyone know if type-S mortar will have any problems being continually exposed to the indirect heat from the insert? I doubt it would ever reach more than 200 degrees or so.

Thanks!

Mortar does not really dry out. - It cures as the moisture reacts with the cement over time. As long as it has moisture, it continuses to cure, but at a much slower rate as as it ages.

You should git it a couple of weeks, although it could be less depending on the temperature.
