Figured I'd go through the process of how I get the Heritage up to 600° since there have been some questions and remarks about getting a Hearthstone up to certain temps. This isn't a perfect illustration, as the photos were taken quickly on an iPad later in the day so the lighting is poor, with a lot of reflections, and I did not take photos of the splits that were used.
First, I started with about six medium sized splits (on the smaller end of the medium scale). In this particular instance I am starting on a hot bed of coals with the stove top sitting at about 300°.
Fire has been going for about 10-15 minutes. The air controls are completely open and the pipe damper is open. Top center stone is at 377°
After that photo was taken the air controls were adjusted to 60% open. Pipe damper is still open.
5-10 minutes have passed. Air controls are still 60% open with the damper open. Top center stone is at 412°
After that photo was taken the pipe damper was closed and the air controls were adjusted to about 45% open.
10 minutes have passed. The pipe damper is closed with air controls still at 45% open. Top center stone is at 519°
After that photo was taken the air controls have now been adjusted to about 15% open with the pipe damper closed.
This photo shows the control settings at this point (note that the Rutland is lagging behind in temperature readings):
5-10 minutes have passed. Air controls and pipe damper remains the same. Top center stone is at 545°
5 minutes have passed. Air controls are now closed. Pipe damper remains closed. Final shot. Top center stone is at 595°
Stove topped out at 610° briefly before coming back down.
And there you have; A Hearthstone at 600°.
