CLEARANCES
WARNING
Follow these instructions carefully to ensure safe installation.
Failure to follow instructions exactly can create a fire hazard.
•The combustible area above the facing must not protrude more than ¾(19mm) from the
facing; if it does, it is considered a mantel and must meet the mantel requirements on the
following page.
•When selecting non-combustible materials for use in the installation, take note of the
material’s propensity to absorb and conduct heat. Materials such as metal, stone, and
ceramics may transmit heat more readily than other building materials.
•Only non-combustible materials (i.e. brick, tile, slate, steel, or other man made materials with a
UL fire rating of Zero) may be used in the construction and installation of this fireplace. Any
material must be fastened to surrounding framing. NOT to the face of the fireplace.

Commonwealth of Massachusetts. If this appliance is installed in a dwelling, building or structure
used in whole or in part for residential purposes and the installation includes a horizontal vent
termination that is less than seven (7) feet above the finished grade in the area of the venting,
including but not limited to decks and porches, a hard-wired carbon monoxide detector with an
alarm and battery back-up must be installed on the floor level of the dwelling, building or structure
where the appliance is to be installed.
Additionally, a hard-wired or battery operated carbon monoxide detector with an alarm must be in-
stalled on each additional level of the dwelling, building or structure served by the appliance. It shall
be the responsibility of the property owner to secure the services of qualified licensed professionals
for the installation of hard-wired carbon monoxide detectors.
In the event that the horizontally vented appliance is installed in a crawl space or attic, the hard-
wired carbon monoxide detector with alarm and battery back-up may be installed on the next
adjacent floor level.
In the event that this requirement cannot be met at the time of completion of the installation of the
appliance, the owner shall have a period of thirty (30) days to comply with the requirement. However,
during said thirty (30) day period, a battery operated carbon monoxide detector with alarm must be
installed.
Each carbon monoxide detector as required in accordance with the above provisions must comply
with NFPA 720 and be ANSI/UL 2034 and IAS certified.
In addition, when the vent termination is less than seven (7) feet above finished grade a metal or
plastic identification plate must be permanently mounted to the exterior of the building at a
minimum height of eight (8) feet above grade directly in line with the exhaust vent terminal. The sign
shall read, in print size no less than one-half (1/2) inch in size, “GAS VENT DIRECTLY BELOW. KEEP
CLEAR OF ALL OBSTRUCTIONS”.
A COPY OF THESE INSTRUCTIONS PLUS ALL VENTING INSTRUCTIONS WHICH IN-CLUDE PARTS LISTS,

VENTING
WARNING
This fireplace must be vented to the outside. The venting system must NEVER be attached to a
chimney serving a separate solid fuel burning appliance. Each gas appliance must use a separate
vent system. Do not use common vent systems.
INSTALLATION PLANNING
The 512 VU-THRU, and 612 VU-THRU use 4x6 Direct-vent pipe.
There are two basic types of direct-vent installation:
•Horizontal Termination
•Vertical Termination
It is important to select the proper length of vent pipe for the type of termination you choose, taking
into consideration wall thicknesses.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise
desired. All horizontal run of venting
must have ¼” rise for every 12” of
horizontal run.
WARNING
Never run the vent pipe level or downward. This may cause
excessive temperatures which could cause a fire.
FOR VERTICAL TERMINATION
Measure the distance from the Horizontal Vent Center Line (see diagram on page 8). Add the ceiling
thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the
roofline.
NOTE:
You may use two 45elbows in place of a 90elbow. You must follow rise to run ratios when using
45elbows. The appliance is approved for use with three 90elbows maximum of a combination of
90and 45elbows up to a maximum of 270.
For two-story applications, firestops are required at each floor level. If an offset is needed in the attic,
additional pipe and elbows will be required.
It is very important that the venting system maintain its balance between the combustion air intake and
the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN OUTSIDE CHASE
A chase is a vertical box like structure built to enclose venting that runs along the outside of a building. A
chase is required for such venting.
NOTICE
Treatment of firestops and construction of the
chase may vary from building type to building
type. These instructions are not substitutes for
local building code requirements.
NOTICE
When installing in a chase, you should insulate the chase as you
would the outside walls of your home. This is especially
important in cold climates. Insulation should be considered a
combustible material. Maintain proper clearances to
combustibles.

16
VENTING
Install a Simpson Duravent (Or equivalent) wall thimble, part number 46DVA-WT (not supplied by SPARK
MODERN FIRES), where the pipe passes through a wall to retain any insulation in the wall and to
maintain proper clearances. If the wall being penetrated is constructed of non-combustible material
only (i.e., Masonry block or concrete), the wall thimble is not required; and a hole with zero clearance is
acceptable (6 ⅝” hole).
NOTICE:
Venting terminals shall not be recessed into a wall or siding.

17
VENTING
This SPARK MODERN FIRES Gas Fireplace has been tested and listed for installation with 4” X 6 5/8” M&G
DuraVent GS/Pro®, Selkirk Direct-Temp®, Security Secure Vent™, AmeriVent Direct™, Metal Fab Direct
Vent and ICC EXCELDirect venting components. Although you may use the pipe components (straight
pipe, elbows, etc.) from any of the listed manufacturers, you may only use the vent terminations (caps)
listed in the chart on the following page. For installations where a snorkel is needed, please note that
only three snorkels are approved for use. Please plan your installation accordingly.
For all specific venting installation requirements, follow the installation instructions included by the
venting manufacturer with the venting system components you have chosen.
PLEASE NOTE:
•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 total venting may not exceed 30 feet
of vertical rise and/or 12 feet horizontal run. Refer to the venting charts on pages 16 for specific
details while you plan your installation. Note: The number of elbows impacts the maximum
allowable horizontal vent run.
•There should be a 1 1/2” overlap of the vent and combustion air tubes, when telescopic joints
are used.
•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 B419.1, Natural Gas and Propane Installation
Code and the requirements shown on page 14 of this manual.

Just as with any other vented device, vertical vent rise creates draft (negative pressure) in the firebox as
the exhaust gases heat up. If this draft becomes excessive, it can affect the performance or appearance
of the fire. The SPARK MODERN FIRES Gas Fireplace includes an integrated air restrictor that can used to
balance the draft in the fireplace to the optimal level for installations where excessive draft might occur.
The SPARK MODERN FIRES Gas Fireplace will ship from the factory with the air restrictor set to the #1
position. If the licensed fireplace installer determines that draft reduction is necessary, loosen the
fastener on the dial and make small adjustments from #1 to #4 until a satisfactory result has been
achieved.
The air restrictor dial is located on the flue side of the firebox when
viewed from the front. To access, remove the lower air screen and side
panels. Once satisfied with the air restrictor adjustment, secure its
position by tightening all hardware.

18
VENTING
SPARK MODERN FIRES flue restrictor kit, part #11317
Some vent configurations may create excess draft within the fireplace. Excess draft can cause
issues such as a rapid, or “nervous” flame picture, undesirable flame color, or pilot lifting which may
prevent the fireplace from staying lit. In these circumstances it may be necessary to install the flue
restrictor kit part #11317 in the venting system. It is permissible to install this restrictor at the vent cap
should the venting system already be installed. Secure the restrictor plate with the included #10 sheet
metal screws.
Vent chart for 512 VU-THRU and 612 VU-THRU.
Power vent runs of up to 110ft with (6) 90elbows are permitted when using the SPARK MODERN
FIRES power vent kit PV-800HZ. Refer to power vent instructions for additional power vent
installation and operation information.
