I have a quadrafire 5700 stove. I have very seasoned wood and can achieve 475 to 500 degrees on my stove. However, I find that it hard to maintain this temp unless I am constantly feeding wood into the stove therefore I usually run the stove at approx 350. Is this normal to have to constantly feed the stove in order to hold this high temperature. Is 500 degrees to high of a temp for this stove?
