2. Install the metal edging on each side of the doors,
making sure that the edges fit nicely with the arch
edge above. There are right and left side expanded
metal pieces. The expanded metal is correctly
installed when the expanded metal is facing upwards,
to catch the mortar. A wider steel lintel bar may be
required for heavy rock.
3. Cover the rest of the area with wire mesh, or metal
lath, flush with the heavy expanded metal. Make sure
nails or staples used for fastening mesh penetrate the
studs at least 1".
4. Mortar must be "thin set" or "thin bed" type, inherent-
ly polymer modified. Do not add water to the mixture
(this applies to the grout as well). If the mortar is not
modified, you should add a synthetic latex additive.
Mix to a firm, moist consistency.
5. Using a plasterer or mason's trowel, apply a scratch
coat that covers the wire mesh. Let the mortar set
before adding another coat. This will take several
hours. Afterwards, apply a thinner coat and the facing.
Do not
spread plaster over more than a
workable area so that the mortar will not set before
the facing is applied.
6. If additional mortar is required, use a grout bag to fill
in the joints. Take extra care to avoid smearing on the
surface of the facing.
NOTE: If you wish to cover the top louver using an FDK-
1 you must provide access to the air control located
inside the right side of the top louver opening. The FDK-
1 has a removable panel which permits access to the air
control. The masonry which covers this panel should be
installed in such a way that it can be
removed if necessary.
REMOTE VENTING
The gravity vent system can distribute air
to an upper level or a room next door
without an extra blower. If you use two
gravity vent kits you may block off the
upper louver area with the desired fac-
ing. The central heat option allows heat
to be sent up to 50 ft. away. (Figure 21)
illustrates various certified ways of incor-
porating the two systems.
THE GRAVITY VENT SYSTEM (FDV)
The FDV kit includes:
- A grill
- A grill adaptor
- A B-vent starter section
- A shut-off damper (do not use
with upper louvers blocked)
IMPORTANT: No substitution of any of these parts is
allowed.
Fireplaces parts have the correct clearances. These
clearances must be maintained for your safety.
The FDV system incorporates standard 8" B-vent com-
ponents for installation. Single wall pipe is not allowed
due to the high temperature of the air in a gravity vent
system. Any listed brand of 8" B-vent pipe may be used
and is not a part of the FDV. The maximum pipe length is
15 ft. from the top of the fireplace to the outlet. The B-
vent components can be replaced by UltraBlack double
wall black connector made by ICC only.
NOTE: If two gravity vent lines are installed, then two
FDV kits must be ordered.
(Figure 23) indicates the minimum clearances and fram-
ing dimensions. Passing through a combustible wall or
ceiling requires a minimum clearance of 2" from com-
bustibles.
WARNING: Every measurement and clearance on the
illustrations must be followed to assure safety of the
installation.
Installation
CAUTION: Do not replace the grill from the FDV with
shutters. Do not allow heat to be trapped in the gravity
vent system.
1. Plan the gravity vent run first. Be aware that the max-
imum actual pipe length between the top of the fire-
place and the outlet is 15 feet. There is no maximum
number of elbows in a run, but the run must never go
in a downward direction as this can trap heat in the
gravity vent system.
