CAUTION:
Do not light a fire until you read and completely understand the Operating Instructions that follow. If you
have any questions or concerns, please contact
Fireplace Doors Online
before proceeding.
GENERAL SAFEGUARDS:
Excessive heat can cause damage to the
Aluminum
ZC Glass Doors and/or loss of temper in glass resulting in glass
breakage. A very hot wood or gas fire, hot coals, embers, ashes, and/or logs coming in contact with the back of the
enclosure can cause discoloration or more serious damage to the enclosure finishes. This type of damage, caused
by over-heating, is considered abuse and is not covered under warranty.
Do not burn trash, construction materials, pressure treated lumber and/or railroad ties in your fireplace. The intense
heat that these types of materials can produce can damage your
Aluminum
ZC Glass Doors and the fumes from burn-
ing these types of materials can create a serious health hazard. Dry, seasoned hardwood is the recommended fuel.
CAUTION
:
CMC
uses very high quality tempered glass but tempered glass is breakable like any glass. It is the opera-
tor’s responsibility to read, understand, and follow the instructions below and to exercise due caution. The most important
precaution is to keep the glass doors open when the fire is burning. The tempering process makes the glass stronger and
more resistant to heat and impact but not impervious. Avoid striking the glass with logs or fireplace tools. If tempered
glass does fail it breaks into small pieces. Glass pieces may fly about the area. Never sit, or allow children or anyone else
to sit, close to the glass when the fire is hot. Use a protective hearth rug or other suitable non-flammable protection in front
of the fireplace to protect wood floors and/or synthetic carpets. In the event that the glass should break, the resulting small
pieces could burn skin or damage flooring.
OPERATION:
Aluminum
ZC Glass Doors are designed to be used with the glass doors open and the screens closed when the fire is
burning. You will get the maximum heat from your fireplace with the glass doors open. Whether you use the OEM
screens that came with your fireplace or order new screens with your ZC Glass Doors, the screens must be kept
closed at all times when a wood fire is burning except when loading or maintaining the fire.
Build and maintain small to moderate wood fires. Fireplace grates and/or andirons must be properly sized to allow at
least 5 inches of clearance between the fire and the ZC Glass Doors. A roaring fire, or any fire allowed to burn too
close to the
Aluminum
ZC Glass Doors, can overheat and damage the frame, glass, finish, and/or discolor the metal.
Damage caused by overheating of the ZC Glass Doors is considered abuse and is not covered under warranty.
Never leave the room with both the glass doors and screens open. Under normal operating conditions the glass
doors will be open and the screens will be closed. Upon retiring for the evening, or leaving the room for an extended
period, the glass doors can be closed to provide maximum spark protection. Before closing the glass doors ensure
that the wood fire is under control and of moderate size or smaller. The
Aluminum
ZC Glass Doors are designed with
air gaps between the glass panels that will allow for enough air to support combustion and to help to keep the ZC-
Fireplace cool. The fireplace flue damper should be left fully open. Once the fire is completely extinguished, close
the fireplace flue damper and close the glass doors to minimize heat loss up the chimney.
Aluminum
ZC Glass Doors used in combination with Gas Logs must have the glass doors open and the screens closed
when the Gas Logs are in operation to ensure adequate air flow to the Gas Logs. The Gas Logs must be properly
sized to allow at least 5 inches of clearance between the fire and the Fireplace Enclosure. Unlike a wood fire that
modulates heat output, gas logs can produce a lot of heat constantly over an indefinite period of time. Burning Gas
Logs with the glass doors closed can overheat the glass doors, the ZC-Fireplace, and/or the Gas Logs and cause
damage to any or all of the components. Read and follow all instructions provided by the Gas Log manufacturer.
MAINTENANCE:
CAUTION:
The
Aluminum
ZC Glass Doors and the glass must be at room temperature before cleaning.
Closing the glass doors to secure a dying fire may result in smoke residue or soot accumulation on the glass. If
cleaned regularly this staining can be removed using glass cleaner or a mild household cleaner. Avoid cleaners that
contain ammonia. Spray on, let soak for a few minutes, and wipe clean. Repeat as necessary.
Heavier, long-term build up may require the use of a glass cleaner specifically formulated for removing wood smoke
residue. These glass cleaners are available from
Fireplace Doors Online
. Never use oven cleaner.
CMC
uses Anodized or heat resistant Powder Coat finishes on
Aluminum
Fireplace Enclosures. These finishes require
only an occasional wipe with a damp cloth to maintain the factory finish. A mild household cleaner may be used if
necessary. Do not use cleaners that contain ammonia. Do not use harsh, strong, or abrasive cleaners.
Polished metal parts of the enclosure (brass, copper, etc.) are Anodized to prevent tarnishing. Wipe with a damp soft
towel or dust cloth only. The use of metal polish or strong cleaners will damage the finish.
