Design Specialties offers Doors Plus Spray Cleaner which can be purchased from your local authorized dealer. It is recommended for use on Design Specialties Fireplace Doors. It can be used on glass as well as steel and aluminum. The rods of the mesh curtain should be sprayed with silicone occasionally to keep their operation smooth.
CAUTION: Never use oven cleaner or products containing caustic agents to clean the enclosure. Clean and lubricate appropriate areas only when their surface is at room temperature and no fire is present.
Glass Breakage Prevention:
To obtain the maximum efficiency from your fuel, you may leave the doors open while you are in the room. Upon retiring or leaving the room, however, make sure the doors are closed and the fire has died down. This will reduce heat loss and prevent fires caused by sparks escaping into the living area. Before closing the doors, even when you remain in the room, make sure that the fire is burning at a stable level. Close doors half-way to "warm them up" before closing completely when a fire is burning.
Fire Safety Information:
For maximum safety, burning logs should be kept as least 6 inches from the glass at all times. Do not sit close to the glass. Also, never burn trash, construction scraps, railroad ties, or any other highly flammable material in the fireplace. Intense heat caused by these items can cause the glass to lose strength and resilience, which will result in glass breakage.
