Carefully fit the door into the firebox opening, making sure not to scratch the finish. Align the unit snugly into the opening. Holding the unit in place, reach inside to mark where the bottom brackets meet the floor of the firebox. Use a thick marker, such as a Sharpie, and mark through the grooves in the brackets.

Make sure to drill straight down or you may have trouble getting the screw into the hole. Be sure to vacuum out the dust in the holes, too. Using a hammer, gently tap a lead anchor into each hole until it's flush with the surface of the surrounding brick.

Put on a pair of gloves and unroll the fiberglass insulation that comes with the door. Tear off pieces to fit into the channels at the two sides and the top of the unit.

Stuff the insulation into all three channels. Don't worry about keeping the fiberglass fluffy, as you would with wall insulation—it's mainly there to seal the door and keep smoke from seeping out, and to protect any finish on the door frame from the heat. Carefully slide the door into the firebox opening. Check that no insulation is sticking out around the edge of the frame. Make sure the door is flush to the face of the firebox. Reach inside and twist sheet-metal screws through the bottom brackets and into the lead anchors.

Be careful not to tighten the screws too much or you may loosen the anchor in the brick or break off the head of the screw. The clamps that hold the door to the metal lintel bar at the top of the firebox are adjustable. Make sure the clamp is positioned so it can span the depth of the lintel. Finger-tighten the thumbscrew to clamp the hardware onto the lintel. When you can't turn the thumbscrew anymore, use a pair of pliers to give it another quarter-turn.
