How to Install Fireplace Backs

Updated February 21, 2017

A fireplace back, also known as a fireback, is a heavy-metal or cast-iron plate used to reflect heat from a fireplace into the room. The fireback generally improves the fireplace's ability to produce and radiate warmth. Fireplace backs are available for wood-burning or gas-powered fireplaces, but they are not interchangeable. You can install either variety in a few minutes with common hand tools.

Ensure that the fire is extinguished and cold. Remove the log grate and sweep out ash and debris with the dustpan and broom.

Twist a retaining bolt into the hole on the left and right edges of the fireplace back. Do not tighten the bolt all the way.

Insert the fireplace back into the fireplace and position against the brick at the back of the fireplace.

Tighten the retaining bolts through the fireplace back and against the side walls of the fireplace with pliers to hold the plate firmly in position.

Shut off the gas to the fire to extinguish the burner below the gas logs. Wait for the appliance to cool completely.

Disconnect the gas logs from the gas line with the pliers to remove the log assembly.

Remove the two screws at the back of the gas fireplace near the bottom and top with the screwdriver to remove the retainer brackets.

Insert the bottom edge of the fireplace back into the slot at the bottom rear of the gas fireplace at an angle, then tip the plate upward and push toward the back wall of the fireplace.

Replace the upper and lower retainer brackets with the screws to hold the fireplace back in position. Reconnect the gas logs to the gas line and tighten the coupler with pliers.
