Who It’s For

An open masonry fireplace sends most of its heat up the chimney. You need an insert sized to your room. The Supreme Lumis 16 is for the home with an existing masonry fireplace that wants an arched-door wood insert rated for up to 750 sq ft.

What Makes It Special

It turns a masonry fireplace into a clean, efficient, modern heat source with a cast-iron interior. Two blowers with speed control and an on/off switch spread the warmth, and a surround comes standard.

A patented automatic air control cuts back the combustion air after lighting to the burn rate you set, so the fire settles into a steady, consistent burn. It is a clean-burning certified, non-catalytic insert from a family company in its second generation.

Possible Downsides

• It is a wood fire. You haul and store wood, clean ash, and sweep the chimney.
• Check the opening first. Your installer confirms the fireplace fits the insert.

If you want an old fireplace to heat the room, the Supreme Lumis 16 is the right decision. The fireplace becomes the room’s heater.

Choose the arched door; the other style is available too.
