Is it safe to burn my Acucraft Fireplace System during the night when we are not watching it?

Yes. Our gasketed doors provide an airtight seal. By latching the doors, our wood-burning fireplaces will continue to safely burn throughout the night. Safety is a major concern, which is why our Hearthroom wood fireplaces are tested and listed to exceed industry required standards (UL-127) and can be burned for long periods of time, unattended.
