Model Details

Safety First
Because our inserts were designed to deliver maximum BTUs to provide the best heating solutions for your home, the units will become hot to the touch. Consequently, all Monessen direct vent fireplaces come standard with a certified safety barrier. The screen barrier affixes to your fireplace and has been approved by a third party testing agency to conform to specific standards designed to prevent injury from hot glass.

Natural Flame burner system
Enjoy dancing, realistic flames — The aluminized pan burner produces realistic, randomly dancing flames. Its large ember bed and new, randomized massive log set add to the overall fire viewing experience.
