For all specific venting insta
requirements, follow the installation
instructions included by the venting
manufacturer with the venting system
components you have chosen.
Please note:
For venting configurations that include no
vertical rise, a total horizontal vent run of up to
12 inches is allowed. However, if your
installation has room to add a vertical pipe
section, we suggest adding at least one fo
vertical rise to the system.
For venting configurations that include vertica
rise, it is assumed that the installation will
include at least one 90° elbow. Up to three
additional 90° elbows (or equivalent 45°
elbows) may also be used. The number of
elbows impacts the maximum allowable
horizontal vent run.
The total venting may not exceed 60 feet of
vertical rise and/or 20 feet horizontal run.
Custom testing is available for installations ov
the limits for approvals. Refer to the Venting
Chart on the following page for specific details
while you plan your installation.
Many installations will involve venting directly
through standard 2 x 4 or 2 x 6 construction

to accommodate those installations without the
use of any additional venting components other
than a standard horizontal cap. See the char
above for a list of approved vent caps.
If the Flatfire fireplace will be installed on an
interior wall or other location that precludes
venting directly through an outside wall to a
horizontal vent cap, or if the distance to the
outside wall exceeds 12”, one or more elbows
will be required to allow addition of the require
vertical venting to the installation.
When vertical venting is required, the fireplac
venting may be terminated with either a vertical
or horizontal vent cap depending on the
specifics of the installation. Refer to the Venting
Chart on the following page for specific venting
requirements and the chart above for a list of
approved vent caps before you plan your
installation.
A minimum clear space of 1½” must be
maintained around the vent pipe where it
penetrates the first combustible wall adjacen
the fireplace (either the outside wall for the
direct-through-the-wall installation or the
partition wall for the 45° or other interior wall
installations) and must also be maintained
where the vent pipe penetrates any other
interior or exterior wall, ceiling, or roof.
The Flatfire may also be installed in front of an
exiting fireplace opening. Refer to the vent
manufacturers’ instructions. Use the vertical
venting column (0 feet horizontal run) in the
venting chart to determine the requirements
depending on the height of chimney.
The location of the vent termination must meet
the requirements of the current edition of ANSI
Z223.1/ NFPA 54, National Fuel Gas Code or
CAN B149.1, Natural Gas and Propane
Installation Code and the requirements show

Unpacking and Assembly Preparation
Flatfire
The fireplace components are shipped in three
cartons. The first and largest carton contains:
this Flatfire manual,
fireplace mounting template,
bag of glass burner media,
remote control handset,
hardware bag,
two relief doors with gaskets,
four outer decorative panels,
firebox with caution label attached, and
mounting plate.
The second carton contains the fireplace surround.
The third carton contains the vent starter pipe and
vent pipe shields.
To unpack the Flatfire, follow these steps:
1. First lift and remove the section from the carton
containing the firebox. Carefully unpack the
contents and set aside. This should include the
manual, the wall mounting template, the bag of
glass burner media, the remote control handset,
a hardware bag and the two relief doors with
gaskets.
2. Next lift off the glass protector board and
remove the other sections from the carton.
Carefully remove the contents. This includes
the four decorative panels that will be attached
to the fireplace during assembly. Note that the
right panel has a touch pad control panel and
cable attached. Use special care when
unpacking and handling the right panel to avoid
damaging the cable or pad.
3. Next, remove all remaining packing material
from the carton.
4. Lift the firebox out of the carton. Note the
caution label is attached to the firebox. The
best place to lift is at its sides. Finally, remove
the fireplace mounting plate up and out of the
carton. This should be all the parts from the first
carton.
5. Next, unpack the fireplace surround from the
second carton and set aside on a soft surface
for later use.
6. Finally, unpack the vent starter pipe (with
attached gasket) and the vent pipe shields from
the third carton and set aside for later use.
Before you begin the fireplace mounting process
there are several installation requirements that must
be met. Careful planning will make the installation
easier to accomplish and will reduce the chances of
encountering problems after you start.
1. The fireplace is designed to be wall-mounted
using four lag bolts to secure the fireplace
mounting plate to the wall structure. The
mounts are located 16” on center and 24” on
center to correspond with standard building
construction. If your home has non-standard
construction or the location you have chosen for
the fireplace does not have wall studs that
correspond to location of the fireplace mounts,
modifications to the wall structure will be
needed. It is critical that the four lag bolts
that are provided for mounting the fireplace
are firmly imbedded into the wall structure
at all four locations.
2. A hole must be provided in the wall for the vent
to pass through. The hole must be large
enough to provide 1½” clearance around the
outside of the vent pipe and to allow for
installation of the vent heat shields that are
provided with the fireplace. Follow the hole size
requirements that are provided below exactly to
avoid problems. If the location you have chosen
does not allow for 1½” clearance to wooden
framing in the wall, modifications to the wall
structure must made to obtain the needed vent
pipe clearance.
3. All required minimum clearances to adjacent
combustible materials (including side walls,
ceiling and floor) must be achieved with the
position you have chosen. Refer to the
Clearance Information in the Installation
Overview section (page 5). The listed
clearances are measured from the both the
outermost front edges of the fireplace surround
and from the edge of the glass frame. In
addition the requirements for clearance to
combustible materials inside the house, there
are specific requirements and limitations that
must be met for the location of the vent terminal
relative to doors, windows, corners, eaves, gas
supply components and other structural
elements of the house. Refer to the specific
requirements in the Vent Terminal Clearances
(page 10). Again, plan the installation in
advance to avoid problems.
4. The gas supply line must be located within a
specific area behind the fire
place.

Outer Vent Heat Shield and Termination Installation
PARALLEL INSTALL
ATION ON OUTSIDE WALL
Steps to install the Outer Vent Heat Shields and
Vent Termination (Parallel Installation):
. Before you install the horizontal vent
1
termination, you must first install the sec
ond
halves of the two telescoping vent pipe heat
shields. Each shield half simply slips over the
half you previously
attached to the fireplace
mounting plate and can now be seen inside the
vent pass-through in the wall.
2. Install the outer shield first and the inner
second. Leave about 1¼” of the shields
protruding past the house sheathing.
3. Install the horizontal vent termination (vent cap)
by first removing the two mounting straps as
they will not be used. Be sure the arrow on the
cap (if present) is pointing up and rec
onfirm that
all the vent cap location requirements and the
vent manufacturer’s requirements are met.
4. Slip the inner and outer vent termination pipe
onto the vent starter pipe taking care to align
s
the inner and outer pipes to prevent damage.
5. Slide the vent termination (cap) into the sid
ing
recess (or vinyl siding shield) until it bottoms
out.
Note: The rear surface of the vent termination
will push the telescoping vent pipe heat shields
inward. When the vent termination is in place
the heat shields will just touch t ar surface
he re
of the termination.
6. Pull the vent cap away from the sheathing and
install a small bead of non-hardening silicone
sealer around the cap perimeter. Push the cap
in place.
7. Install the mounting screws (included with the
cap) to hold the vent cap to the sheathing See
the venting manufacturer’s instructions for the
location of the mounting holes.
Typical mounting hole locations are shown in
the illustration at right. Refer to the venting
manufacturer’s instructions for more information

when the fireplace is installed on an interior wall
of the house will vary depending on the location
of the fireplace on the wall, what is on the back
side of the wall, where the vent termination will
be located (roof or exterior wall) and on other
code requirements for the location of the vent
termination. However, the maximum vent
length, measured along the centerline of the
pipe, from the back of the fireplace to the start
of th not exceed 30 feet,
including a m of 20 feet of vertical rise
and a maximum of 10 feet of horizontal run. If
more than two 90° elbows (or equivalent 45°
elbows) are needed for your installation, the
maximum amount of horizontal run allowed is
reduced. See the Venting Chart on page 7 for
specific information. It is important to plan the
installation in advance so that you can
accurately locate the any wall or ceiling passthrough’s and the vent termination on the
exterior wall or roof. The vent pipe sections are
available only in certain increments of length
and in adjustable length sections. Plan carefully
before you start!
2. You will find it helpful to leave access to the
area behind the partition wall to facilitate
installation of the vent components. The pipe
sections may have twist lock connections which
will be difficult to execute without good access.
