Electric fireplaces
A slimmer way to build a linear fireplace wall
Allusion Slim is designed for a flush installation in a 2 x 4 wall. A 12-inch-tall viewing area brings the flame into focus, with 40-, 50-, 60- and 72-inch models for compact and wider walls.
Performance Highlights

Keep the wall clean and the fire visible
Choose flame and ember-bed colors, or enjoy the display without the heater. Compatible Crestline kits are offered only for the 50- and 60-inch models in this catalog.
Fuel Details
Electric operation. Confirm the circuit, connection method and finishing depth in the SF-ALLS40/50/60/72 manual. The face width differs from the framing opening.
