CMC Aluminum Glass Doors User manual

ATTENTION: Installer please leave these Instructions with the homeowner.

 CAUTION: All Glass Doors for ZC-Fireplaces are engineered with air spaces around the frame and air-gaps in the
glass. These air-gaps are essential to help cool the ZC-Fireplace should the glass doors be closed accidentally during oper-
ation. Figure 4 shows the air-slots in the Legacy ZC Glass Door frame. Never insulate or seal the enclosure frame.
Under no circumstances should these air-gaps be tampered with or altered in any way.

 Remove Cabinet Mesh Screens from the enclosure if so equipped. Set the screens aside in a safe place.
○ If Hanging Mesh was ordered see instructions on Page 4. Attach the mesh curtain before installing the enclosure.
NOTE: Skip this step If the OEM screens that came with the fireplace are to be retained.
 Attach an L-Bracket (I) to all four corners of the enclosure. Use 1/4-20 x ⅜” Phillips head machine screws (A) into the
tapped 1/4-20 holes in the horizontal legs of the enclosure corner brackets. (Figure 1) Thread in the Pressure Screws.
Alternate Method: Track nuts (C) are provided to allow mounting the L-Brackets in another location on the enclosure
frame if there are obstructions to the standard corner mounting position.
 Set the Aluminum ZC Glass Door into the ZC Fireplace firebox opening.
○ Check that the OEM screens (if retained) will operate smoothly with the new Aluminum ZC Glass Doors installed.
○ If the OEM screens will not operate correctly contact your Stoll dealer to order screens to fit the new ZC Glass Doors.
 CAUTION: Screens must be installed and operate properly on your ZC-Fireplace before lighting a fire.
Never light a fire without working screens installed on the ZC-Fireplace.

 Center the Legacy ZC Glass Door frame in the fireplace opening.
 Slide the L-Brackets close to the sides of the fireplace. Tighten the 1/4-
20 x ⅜” machine screws.
 Tighten the Pressure Screws evenly. Don’t over-tighten. (Figure 2)
NOTE: Flat Brackets (J) are provided if the fireplace design requires
longer brackets. Use the 1/4-20 x ¼” Machine Screws (B) to attach the
Flat Brackets to the L-Brackets. (Figure 3)
 Replace the Cabinet Mesh Screens if so equipped.
 Check that the ZC Glass Door is aligned level, straight, and square.
NOTE: Failure to align the ZC Glass Doors properly may result in glass
breakage or other damage directly attributable to improper installation.
NOTE: If your are using the OEM screens that are part of the ZC-
Fireplace check again that they operate freely.

 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.

OPTIONAL MESH SCREEN KIT INSTRUCTIONS:
 Install the rod brackets (b) using 1/4” screws (e) into the tapped hole on the vertical leg of corner brackets. (Figure 6)
 Install a mesh curtain (with the handles towards center) on each side of the curtain rod (a). NOTE: To create a pleated
appearance in the mesh curtain, twist each curtain ring one-half turn as it is installed on the curtain rod.
 Insert the curtain rod ends into each rod bracket in turn. NOTE: To keep the curtains from sliding to the center, leave the
last curtain ring loose until the rod is installed then hang the loose rings on the hooks provided on each Rod Bracket.
 Attach the curtain rod center bracket using a ⅜” screw (d) and track nut (c). (Figure 7) It may be easier to insert the
screw (d) through the center bracket, loosely thread on the track nut, and then slip the nut into the frame track. Tighten
the screw securely.
