Installation
1.
Install the expanded metal on the top half of the fire-
place using drill and tap screws at locations shown
(see Figure 19). If there is a bypass rod above the
door, allow for it to come through. For thick rock, the
rod extension (R6414) may be required.
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, inherently
polymer modified. Do not add water to the mixture (this
applies to the grout as well). If the mortar is not modi-
fied, 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 work-
able area so that the mortar will not set before the fac-
ing 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 facing. The central heat option
allows heat to be sent up to 50 ft. away. (Figure 21) illus-
trates various certified ways of incorporating the two sys-
tems.
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. These genuine RSF Woodburning Fireplaces
parts have the correct clearances. These clearances must
be maintained for your safety.
The FDV system incorporates standard 8" B-vent compo-
nents 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 framing
dimensions. Passing through a combustible wall or ceiling
requires a minimum clearance of 2" from combustibles.
WARNING: Every measurement and clearance on the
illustrations must be followed to assure safety of the
installation.
