PLEASE NOTE: Design Specialties doors are hand crafted to the specifications of each order. Due to the nature of the anodization process on aluminum doors, and the plating/powder coating process on steel doors, slight variations in color may occur and will not be considered a warranty issue.


Your Design Specialties fireplace door has been designed and built to provide many years of service.

There are a great many different fireplace designs and variables that may affect how you use these doors. The fireplace doors are primarily used to eliminate cold drafts while the fireplace is not in use and to provide a decorative finished look to the fireplace.

Additional benefits to having fireplace doors are reducing the amount of excess air being drawn up into the chimney while a fire is going. While not airtight, the closed doors restrict the amount of warm room air from being drawn up the flue. If your fireplace is fitted with an outside air vent, the efficiency is increased by increasing the draw of air from the outside. Radiant heat is still produced and transmitted through the tempered glass, warming the room. If your fireplace door is equipped with a room draft control, the draft control can be opened or closed to regulate the amount of additional room air allowed into the fireplace while the doors are closed. Observation of the fire will tell you whether additional air is necessary.

A fire that is "slow" or smokey may require additional air. Opening the draft control increases the air going into the fireplace. The draft control is located in the front bottom of the frame. Two black tabs, one on each side allow you to operate the draft. Moving the control to the right opens the draft, left is closed. For the steel door products we make, the draft control is located behind the glass doors on the bottom center of the frame. It is operated by sliding the control forward or back. Back is open, forward is closed. Depending on the individual fireplace, it may be necessary to operate the fireplace with the fireplace doors in the open position.


Your fireplace door was made from extremely durable materials. Generally, an occasional cleaning is all that's required to keep the function and beauty of the fireplace door. To clean the glass, use a glass cleaner specifically for glass. Avoid any products with lye or abrasives. Some fireplace cleaning products contain both caustic and abrasive compounds. Do not use these products on any glass or metal surface. The use of very fine (0000) steel wool on the glass with a glass cleaner will break up the creosote buildup on the glass easily. Don't use steel wool on any metal surfaces. To clean metal surfaces, use a soft cotton cloth and diluted dish detergent and gently wipe off dust and fingerprints from the metal. Don't scrub or use a strong cleaner as this could remove the protective lacquer coating used on some of our fireplace doors. Avoid leaving fingerprints on delicate polished surfaces. If your fireplace door is equipped with optional mesh curtains, heat and moisture can cause surface rust on the curtain rods making the curtains hard to use. Open the curtains and gently clean off the rods with some steel wool. Should the doors require adjustment, refer to the installation / adjustment instructions that came with the fireplace door.
