Step 1: Install Lintel Clamps to Door

Install Lintel Clamps to Door

First, make the door stand on its bottom or tilt it to one side with your leg, or ask someone to help. Locate the lintel clamps and floor brackets at the back of the door, and use a screwdriver to remove the four screws. Ensure you keep them in a safe place because you are going to need them later.

Now is time to get together the two lintel clamps and fix them on the top part of the door. Tighten the screws that hold the lintel clamps to the top of the door and take note of the slots they should enter.  The slots allow adjustment until you get to the lintel lower part which runs along to the topside of the fireplace opening.

Next, install the L-shaped floor brackets and screw them in place at the bottom of the door. Avoid placing the glass door on its front side, or you may end up causing damage to the surface. This precaution is one of the essential steps when installing a fireplace door.

Step 2: Identify and Mark Screw Holes

Identify and Mark Screw Holes

Carry the door, carefully install it into the firebox opening, and ensure that you don’t accidentally scratch it. Gently align it in place and use a droplight to make the work easier and lighter. Mark the spots in the brackets with a sharpie or any useful marking tools at the spot where the brackets bottom and fireplace floor meet.

Step 3: Use a Drill to Make Holes for Lead Anchors

After marking the spots, remove the door and carefully keep at a safe place. Use a drill with a 5/16-inch bit to drill a hole about 2 inches deep into the marked spots. After that, use a vacuum to blow off the particles from the drilled holes.

Use a hammer to drive in the lead anchor until it is the same level as the brick surface. The drilling should always be made through the brick and not on the mortar to make it firm and difficult to crumble. Keep your hand steady and drill straight to avoid any bend that will prevent the screws from fastening.

Step 4: Add Door Insulation

Add Door Insulation

Wear gloves before unrolling the fiberglass insulation that comes with the fireplace door. You may need to tear off some pieces to make sure they fit into the two sides and the top part of the door. Ensure the insulation goes appropriately into the three channels and do not bother if the fiberglass is not fluffy.

The primary purpose of fiberglass is to seal so well that no smoke goes out of the fireplace. It also helps to keep heat from ruining the finish of the door frame.

Step 5: Hold the Door with Screws

Slide the door carefully into the fireplace’s opening and ensure the fireplace door insulation sticks out on the frame’s edge. The door and the fiberglass should be at the same level before you reaching inside to twist the screws through the brackets and lead anchors.

Use a socket wrench to tighten the screws until they firmly tight to the brick. However, the tightening should not be too keen to avoid damage to the screw or ruining the lead anchors.

Step 6: Hold Door to Lintel with Clamp

You can always adjust the clamps that hold the lintel bar on the firebox. Keep the clamp in such a way that it runs along with the entire depth of the lintel. Use your fingers to tighten the thumbscrew to clamp the hardware and lintel.

Once the thumbscrew is firm, use a pair of pliers to tighten it a little further. Avoid making the screw too tight, so you don’t spoil the clamp.
