How to Build a Fireplace Insert Frame

A fireplace insert frame is a crucial component that secures the insert in place and ensures its safe and efficient operation. Here's a comprehensive guide on how to build a fireplace insert frame:

Materials Required:

Steel angle iron (1/4 inch x 1-1/2 inches)
Sheet metal (18 gauge)
Self-tapping screws
Fireproof sealant

Tools Required:

Angle grinder
Welding machine
Tape measure
Level
Caulking gun

Step 1: Determine Frame Dimensions

Measure the opening of your fireplace and the size of the insert you plan to install. Subtract 1 to 2 inches from each dimension of the insert to allow for clearance and expansion.

Step 2: Cut and Weld Steel Angle Iron

Cut the steel angle iron to the measured dimensions using an angle grinder. Weld the angle iron pieces together at 90-degree angles to form a frame. Ensure the frame is square and level.

Step 3: Attach Sheet Metal

Cut a piece of sheet metal to fit the inside of the frame. Place the sheet metal inside the frame and secure it with self-tapping screws.

Step 4: Position Frame

Place the frame inside the fireplace opening. Center the frame and level it using a level. Use shims if necessary to ensure the frame is level and flush with the fireplace walls.

Step 5: Secure Frame

Drill holes through the angle iron into the fireplace walls. Insert screws and tighten them securely to hold the frame in place.

Step 6: Seal Gaps

Apply fireproof sealant around the perimeter of the frame where it meets the fireplace walls. This will prevent smoke and heat from escaping.

Step 7: Insert Fireplace Insert

Carefully slide the fireplace insert into the frame. Center the insert and ensure it fits snugly. Secure the insert to the frame according to the manufacturer's instructions.

Conclusion

By following these steps, you can build a secure and functional fireplace insert frame. This frame will not only hold the insert in place but also provide a proper seal to ensure efficient heating and prevent fire hazards.
