Regency® Alterra Wood Insert (Small)

The Regency Alterra CI1150 gives an old masonry fireplace a clean, modern face and turns it into a working wood heater. It's a small insert that takes logs up to 18 inches long, with a 0.98 cubic foot firebox.

If your fireplace looks dated, a contemporary insert like this changes both the look and the way the fireplace works. Like any wood insert, it needs a full-length stainless steel liner up the chimney, and we size and install that as part of the job.

What Makes the Alterra CI1150 Different

• Contemporary look. A clean, modern face instead of a traditional insert front.
• Takes 18-inch logs. Standard-length firewood in a small insert.
• Liner planned from the start. We size and install the stainless steel liner as part of the job.

This listing is the current CI1150-1 version.
