Zero Clearance Fireplace Doors

Nightwell Replacement Prefab Fireplace Door Matte BlackDo you have a factory-built fireplace at your home? You will love our prefab fireplace doors. They are easy to install and an affordable option. Also, you get to choose from a wide selection of stunning designs and styles available! Our American-made doors are manufactured in compliance with fire safety standards. If properly installed and maintained, the Zero clearance fireplace doors will always keep you and your family safe and warm during every winter season. Here are some common names for zero clearance fireplace doors - factory built fireplace doors, ZC fireplace doors, prefab fireplace doors - these are all referring to fireplace doors that are compatible with prefabricated fireplaces.

A prefab or zero clearance fireplace glass door is designed to fit fireplaces that were made in a factory. This means that the fireplace will be built with metal on the outside as well as the inside all around the firebox. These types of factory fireplaces will also use a metal chimney or flue liner instead of traditional brick or stone. So it is important to note that prefabricated fireplace doors cannot fit into the traditional masonry fireplaces. This is because the mounting, venting, and safety systems used in these doors are specifically designed to be used only in zero clearance fireplaces. Installing prefab fireplace doors in conventional fireplaces will not just operate poorly but could also pose a safety threat.

So if you want to make sure whether your fireplace is factory-built or not, just look for the serial number, manufacturer sticker, or other markings in the fireplace. If you see brands like Preway, FMI, Majestic, Marco, Heatilator, Superior, Heat-N-Glow, Temco, or others on the fireplace, you will instantly know it has been manufactured in a factory and requires a prefab fireplace door replacement.

At Fireplace Doors Online, we custom design factory-built fireplace doors for almost every fireplace manufacturer in the industry. If you are not sure what size doors you need? We can help you find Prefab doors as per the model number by your fireplace manufacturer. We provide prefabricated doors for the following fireplace manufacturers:

FMI  |  Heat-N-Glo  |  Heatilator  |  Majestic  |  Marco  |  Martin  |  Preway  |  Superior  |  Temco

The dimensions of the doors stated for the above manufacturers are approximate and may not be accurate. So it is recommended that you always submit your measurements for a correct fit, especially if your replacement doors were custom-made or the manufacturer did not update the model number. We ask that you always submit your measurements for a correct fit!

Unlike traditional masonry fireplace doors, zero clearance fireplace manufacturers do not share any standard mounting system. This suggests that every prefab door is installed a little differently in each zero clearance firebox. However, the good news is that we have perfected the fireplace door mounting systems needed for zero clearance fireplaces. So whether an inside fit or an outside mount, these mounting systems will secure the door to any factory fireplace, with just a bit of drilling required in certain cases.

In most cases, you do not need to be a contractor to install a zero clearance fireplace door onto an existing factory fireplace. The door mounting systems we have are extremely easy to use, with minimal drilling or cutting. You may just need to make some frame adjustments as per the installation manual to "square up" the fireplace door. Furthermore, some heavy or large fireplace doors may also require another person's help during installation or when adjusting the frame to be square.

You must get the right doors for your fireplace. We cannot emphasize enough on the fact that installing non-approved equipment on your heating appliance may cause damage to your home and can injure you or your loved ones. Not all doors are designed for prefabricated fireplaces that usually require an air exchange between the inner firebox and outer cabinet. However, here at Fireplace Doors Online, the models we offer are designed with adequate ventilation for your complete protection and enjoyment.

Fast Ship Doors

Norwegian Z Prefab Fireplace DoorWe offer a special line of prefab fireplace doors that come in varying fixed widths. This allows them to be shipped from the manufacturer quicker because the entire door is not custom made. You can select from a range of different opening heights to suit your needs. If your firebox opening is 36", 38", or 42" wide and no more than 24" high these prefab doors will work for your application. These are all inside fit prefab doors. All you have to do is follow the link and select the door that meets your specifications.


Inside Fit Doors

Moonlyte Zero Clearance Inside Fit Prefab DoorThe Moonlyte Zero Clearance is one of our most popular prefab fireplace doors. Inside fit means that it fits inside of the firebox frame and does not overlap it. This provides a nice clean look and make's your prefab fireplace look brand new again. Many of the inside fit prefabricated fireplace doors we offer are completely customizable to fit your exact firebox opening. The Moonlyte model comes with bi-fold fireplace doors but some have the option to select cabinet doors if that is more your style. To order an inside fit door you need to know the height and width measurements, along with your firebox return space. The return space basically indicates the depth of your opening and will determine if you will be able to have mesh curtains installed or not. Some models of inside fit zero clearance fireplace doors are almost totally customizable while others have fixed finishes and glass tints. 



Brookfield Zero Clearance RefacingPrefab fireplace door replacement doesn't get much easier than refacings. They attach to the outer metal shell of your prefab fireplace, but for this to work all four corners of the metal firebox face must be showing. Refacings typically sit flush on the hearth or fascia. You have to align the refacing with the bottom of the firebox and check to make sure the magnets are in the right position to make contact with the firebox facing. Make sure to be extra careful when applying the refacing because the rare earth magnets are very strong and will cause an injury if your hands are in the way. A refacing has bifold fireplace doors or cabinet fireplace doors but also has the added benefit of a large frame with louvers that covers the entire face of your fireplace, allowing for a complete remodel!


4-Sided Overlap Doors

Phoenix 4-sided Overlap Prefab Fireplace DoorSome prefab fireplaces are able to accommodate doors that overlap the firebox opening. Before looking for an overlap door there are a few things you need to find out. If there is any fascia material sticking out from the fireplace it could interfere with the mounting of an overlap door. You also need to check for your damper handle and any other obstructions that could cause problems and interfere with mounting the door flush to the front of your firebox. After that has been established you just need to make sure there is enough clearance around the opening of your firebox to allow for the overlap of your new 4-sided overlap prefab fireplace door.



Direct Vent - Vent-free - Outdoor


Direct Vent Screen w/ LouversDirect Vent Glass Guard

Direct vent fireplace refacings come in a few different styles and setups. Some have louvers and powder coat finishes like the one displayed above. On these models you can choose from a wide range of powder coat finishes and they offer many different types of louver designs. Other direct vent refacings just consist of the outer metal frame and a protective screen like you see in the picture above (right). Both of these styles mount by using rare earth magnets that are inlayed into the frame of the refacing.

Q: Why can't I keep my glass doors closed when I have a fire? You show them closed on your site with fire in them.

  • A: Whether using gas or wood, you need to have your fireplace doors open when using your fireplace.  
    • The primary purpose of the glass fireplace door is to prevent the room's heat from going up the flue when the fireplace is not in use.  
    • The wood and gas need the air circulating through the room to keep a good flame going in the fireplace.
    • Glass fireplace doors use safety tempered glass in them, which can withstand temperatures between 400°-600°F.  If you close your doors while your fire is burning, the temperature can far exceed that and shatter the tempered glass in the doors.

Q: Can I close the glass fireplace doors when the fire dies down on my wood-burning fireplace?

  • A: Yes, as long as there is no large open flame.  The damper needs to be open to allow the smoke to escape.
