Glass Doors for Prefab Fireplace with Stacked Stone Surround - Project #10017

This is a factory built prefabricated zero clearance fireplace with a stone facing and our customer has requested to see how the Brookfield ZC doors will look (see second set of options). We have determined that the Brookfield ZC will not work for this fireplace because the stone at the top overhangs the firebox opening (see image at bottom of page). So we have created examples of the Stiletto ZC door, which will be more appropriate and safe. The Stiletto ZC is an inside fit door that is made with a 1/4" gap all around the frame so that air is allowed to flow into the outer walls of the fireplace to meet code. No mortar is used in this application, making the installation easier.

Supplied measurements:

The stone measures 41 3/4" wide by 21 1/8" high. The Black opening measures 42 1/8" wide by 21 1/5" high.

Recommended make to size:42 5/8" W x 20 5/8"H

Note: If the black metal at the bottom is higher than the hearth, we will need to make the height that distance less.

Previous Examples that Won't Work:

Originally, the customer requested to see how the Brookfield ZC would look on this fireplace. The Brookfield ZC is designed to overlap the black metal face anywhere from 1/8" to 3/4". Assuming that the amount of black metal still exposed between the opening and the stone is in that range, the door would look like the examples we created below. We would need to make the door about 1/2" narrower than the smallest width between the stones and 1/4" shorter in height. This would leave a 1/4" gap around the top and sides that may need to be filled with mortar in order to have a finished look and hide all of the black metal. If a black frame is chosen, mortar may not be necessary but may still be desired. Once we verify just how much black metal is exposed, we will determine how the door will actually fit or whether a different door is more appropriate.

After further review, it was brought to our attention that the stones across the top of the opening are lower than the actual metal opening of the fireplace. When this is the case, we cannot install a door like this because it can cause issues with heat build-up behind the stone at the top. So these examples will not work on this particular application, but for others who have a similar fireplace where the stone work does not extend beyond the face of the fireplace opening, these options may be viable.

Further Comments

The stone measures 41 3/4" wide by 21 1/8" high. The Black opening measures 42 1/8" wide by 21 1/5" high. The stone at the top is lower than the black. The fact that fireplace fascia comes down below the actual metal firebox opening may prohibit us from being able to make any doors for this fireplace. This has to do with the ability to block the heat from transferring vertically between the fascia material and the front face of the fireplace.
