I need some guidance on doing an overnight burn for my Regency H2100 Hearth Heater. For example do I place logs left to right, or front to back? Do I full load the box? Do I damp the unit full down once it gets going? Currently, If I am burning all night, I am putting in a couple to medium size logs about every two to three hours to maintain my house temperature. I would like to learn how to have longer burn times. Thanks!
