CMC Masonry Fireplace Enclosure Instrucciones de instalación
ATTENTION: Installer please leave these Instructions with the homeowner.
IMPORTANT: Check that the Glass Doors in the enclosure are aligned properly.
If the Glass Doors do not close properly, or do not lay flat against the frame, the frame is most likely twisted. It is not unu-
sual to find that a masonry fireplace face is not perfectly flat, plumb, level, or that the opening is not perfectly square. Do
not force the enclosure frame to conform to a fireplace that is not plumb or level. This is less common with flanges.
The most common adjustment on Overlap installations is accomplished by loosening the pressure screws on the side of
the frame opposite the glass door that is away from the frame. Move bottom corner of the frame out until the doors line
up properly. Retighten the pressure screw (s). Any resulting gap can be filled with extra insulation.
Inside-Fit enclosures can be straightened within the opening. Moving the door back slightly from the fireplace face will
create a reveal that will conceal minor gaps. Larger gaps can be filled with insulation or black RTV sealant as desired.
NOTE: Failure to align the Masonry Fireplace Enclosure Glass Doors properly may result in glass breakage or other
damage directly attributable to improper installation.

Installation Instructions
INSTALLATION:
Remove the glass doors from the Fireplace Enclosure frame to make the
enclosure lighter for installation and to protect the finish.
NOTE: Frameless TotalView doors are not shipped installed on hinges.
They are packaged in cardboard inside the master shipping carton.
Remove the Cabinet Mesh Screens from the enclosure if so equipped.
○ If Hanging Mesh Screens were ordered, instructions for installing them
are packed with the screens.
▪ The mesh screen panels will be packed flat between layers of card-
board. Be careful not to discard the screens accidentally.
Set aside all of the parts that were removed in a safe place.
Thread the six (6) Pressure Screws into the tapped holes in the flanges
with the tips of the screws barely projecting through the flanges.
Remove the protective plastic film from any polished metal trim or over-
lay material on the Fireplace Enclosure frame/doors if applicable.
Set the Fireplace Enclosure frame into the fireplace opening.
○ Overlap fit enclosures will cover the edges of the fireplace opening.
○ Inside Fit enclosures will be installed inside the fireplace opening.
Center the Fireplace Enclosure frame in the fireplace opening.
○ Fill the gap between the flanges and the fireplace opening with the
insulation provided. If the gaps are extremely large, extra insulation is
available from your Stoll Dealer.
Snug down the Pressure Screws evenly but do not tighten. (Figure 2)
Replace the Glass Doors. Discard the shipping hinge screws if used.
Use the color-matched hinge pins that are taped to the glass doors if
needed. NOTE: Some hinge styles do not use separate hinge pins.
○ Check that the enclosure is aligned straight and plumb.
○ Use the glass doors to verify the correct position. See Below.
Tighten the Pressure Screws snugly. Do not over-tighten.
Replace the Mesh Screen Doors if so equipped.
○ A shipping spring is used on Mesh Screen Doors. The spring can be
discarded or reinstalled to tighten the screen fit.
PLEASE NOTE: Your CMC Masonry Fireplace Enclosure must be installed and adjusted correctly.
Misalignment of the enclo sure frame can cause improper latching of the glass doors, glass breakage, and/or improper
operation. P lease read and follow the installation instructions carefully. If y ou do not fe el confident that you a re
equipped to complete the installation properly please contact Fireplace Doors Online or arrange professional installation.
New masonry fireplaces must be cleaned and allowed to cure thoroughly before any firep lace enclosure is install ed.

GENERAL SAFEGUARDS:
Excessive heat can cause damage to the Fireplace Enclosure and/or loss of temper in glass resulting in glass break-
age. A very hot 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 Fireplace Enclosure and the fumes from burning
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:
CMC Fireplace Enclosures 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. 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 Fireplace Enclosure. A roaring fire, or any fire allowed to burn
too close to the Fireplace Enclosure, can overheat the frame, glass, finish, and/or discolor the metal. Damage
caused by overheating of the Fireplace Enclosure 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. Open the damper built into your Fireplace Enclo-
sure to allow enough air to support combustion until the fire is out. The fireplace flue damper should be left fully
open. Once the fire is completely extinguished, close the fireplace flue damper, close the damper in the Fireplace
Enclosure, and close the glass doors to minimize heat loss up the chimney.
Fireplace Enclosures 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 Log set 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 Fireplace Enclosure, the 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 Fireplace Enclosure 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 high quality, heat resistant, Powder Coat finishes on Masonry Fireplace Enclosures. This type of finish
requires 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.) have a clear lacquer finish 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.

A WORD ABOUT ENERGY:
Keep your glass doors closed when the fire is out.
Fireplaces are designed to draw air and smoke up the chimney. Even when the fire is cold the warm air created by your
heating system is going up the flue. It is equivalent to having a one square foot hole in your roof. Closing the fireplace
damper helps, but most dampers do not close tightly. Closing the glass doors is like closing your storm door.
If you have vented gas logs installed the fireplace damper is fixed open at all times. Closing the glass doors in your fire-
place enclosure will close off 99% of the fireplace opening and help stop the loss of heated room air up the chimney.
In some cases the chimney flow reverses and cold air is pulled down the chimney. This is quite common in well insulat-
ed homes. Turning on the kitchen vent hood or a clothes dryer pulls cold air in through the fireplace. Glass doors help
stop the cold drafts. For more serious down-drafting CMC makes Air-Seal doors that are gasketed for a better seal.
So keep those glass doors closed any time you are not enjoying a warm fire on your hearth.
