FireRock fireplaces come with a standard 34.5” opening height (with the exception of the Rumford style.) The height extension kit can be used to increase the height of a firebox’s finished opening by almost nine inches.

This accessory is perfect for designs that call for an arched opening that would normally reduce the open area of the firebox.

This is a three-piece unit that includes two side blocks and one back block. This product should be treated as another course at installation. The height extension kit cannot be used with LiteRock or See-Through models.

Note: Please consult local building codes for specifics regarding any masonry fireplace application.
