1) Remove the screw from the vent hole cover
(vent cover 'A') on top of the unit.
2) Take the connector collar and press and
rotate it into the hole to cut through the
insulation layer. Remove the collar and
remove insulation from the collar. The screws
for the inner cover should be exposed.
3) Remove the screws from the inner cover
(vent cover 'B') and slide it back under the
insulation.
4) Extend flex vent and pull the insulation
sleeves over the 8” (203mm) diameter flex
vents. Leave a short section of flex vent
exposed at each end. On one end insert the
collar into the flex vent and use a clamp to
hold the flex vent in place.
5) Use tin snips to cut slits into the rim of the
connector collar. A minimum of four tabs
will be required so cut the slits 1” (25mm)
(i.e. 1” (25mm) wide tabs) apart around the
perimeter of the collar.
6) Install the connecting collar into the top of
the unit until the bead of the collar rests
against the top of the inner top of the unit.
Reach inside the upper louver opening
and use pliers to bend the tabs (minimum
4) out on the connector collar. A hammer
may be required to lightly tap the tabs and
bend them so that they fit tightly against the
bottom of the inner top. Pull the insulation
sleeve down to the top of the unit. Repeat
steps 1-6 for the second flex vent and collar
assembly.
7) Position the vent frames for the Discharge
Grilles into the rough opening of the stud
wall framing. Make sure to add two insulation
strips behind the flanges of the frame prior to
securing to wall. The frames will fit between
studs framed at 16” (406mm) on center. Use
4 nails or screws to mount the frame to the
stud framing.
completing the facing
Facing materials must be thin veneer (non-self
supporting facades) or self supporting facades.
If you are installing a thin veneer facade the
Regency Masonry Retainer Kit is recommended.
All facades must be non-combustible such
as brick, rock or ceramic tile. See Clearance to
Combustible diagram at the beginning of this
manual to determine the extent to which you
must use non-combustible materials. Gypsum
wallboard is not non-combustible.
non-self supporting, thin Veneer
facades installation
1) Install heavy expanded metal only on the
top half of the fireplace using a drill to pre-
drill holes and install using tap screws at
locations as indicated on kit.
2) Install metal edging of kit on each side of
the doors making sure the edges fit nicely
with the arch edge above.
3) Cover the rest of the area with wire mesh
or metal lath, overlapping around the heavy
expanded metal. Make sure nails or staples
used for fastening mesh penetrate studs at
least 1" (25mm).
4) Mortar must be "thin set" or "thin bed" type
inherently polymer modified. If not modified,
you should add a synthetic latex additive.
Mix to a firm, moist consistency. Using a
plasterer's or mason's trowel apply mortar
1/2" (13mm) to 3/4" (19mm) thick to prepared
surface area. Do not spread more than a
workable area so that the mortar will not
set up before stone or brick is applied.
note: remove the fireplace doors and
louvers and store them in a safe place
until all the masonry work is finished.
acid from the cleaning operation will
permanently damage gold plating.
5) If additional mortar is required, use a grout
bag to fill in joints. Care must be taken to
avoid smearing on the surface of stone or
brick. Accidental smears should be removed
only after mortar has become crumbly, using
a whisk broom or dry bristle brush. Do not
use a wet brush or a wire brush.
6) When mortar joints have become firm
(thumb-print dry) they should be pointed
up with a wood stick or metal jointing tool.

8) Insert the connecting collar into the other
end of the 5 ft. (1.5m) flex vent and use an
adjustable clamp to hold the vent in place.
Cut tabs into the rim of the connector collar
(a minimum of 4 tabs will be required). Push
the collar through the 8” (203mm) hole in
the mounting frame. Use pliers to bend out
tabs (minimum 4) to secure the collar to the
mounting frame.
9) Pull the insulation sleeve up the flex vent
to the back of the mounting frame. The flex
vent should now be connected to both the
unit and the mounting frames securely.
Repeat steps 1-8 for the second flex vent
assembly.
10) Install the block-off plate to the unit. The
block-off plate will cover the upper louver
opening of the unit and force the heated
air into the two 8” (203mm) diameter flex
vents. Put high temperature sealant onto
the block-off plate. Mount the block-off plate
onto the front of the unit and cover the upper
louver opening. Make sure that all exposed
holes in the block-off plate are sealed with
high temperature sealant.
note:
Make sure the block-off plate is flush and
fastened tightly to the Regency FP90
Fireplace.
11) The rough opening size for the Chase Vent
Grille is 3” H x 10”W (76mm H x 254mm
W).
WarninG:
A chase vent of 30 sq. inches (194 cm 2 )
MUST be installed in all applications,
otherwise serious overheating of the chase
may result. Use the chase vent supplied
with the FP90 unit only or any equivalent
one with the same or less restriction of air
flow (for U.S. installations only).
12) Recheck all flex vent-work connections to
make sure that they are secure. Install wall
sheathing and cut-out openings for the chase
ventilation, and hot air discharge outlets.
13) Install the Chase Vent Grille and install
the Discharge Vent Grilles for the hot air
outlets.
note:
There must be a minimum of 5" (127mm)
between the gravity air vents.
