be obtained from the following direct vent pipe manufacturers:
Olympia: "Ventis" line
DuraVent: "Direct Vent Pro" line
ICC: "EXCELDirect" line
BDM: "Pro-Form Direct Vent System" line
Selkirk: "Direct-Temp System" line
Also note that if you require a power vent, the vent pipe type will change. Please see section titled,
“General Pipe Requirements & Certified Pipe Manufacturers” for details.
General Building Requirements
This section provides information, diagrams and recommendations related to building requirements for
Lyric fireplaces.
“Zero-Clearance” Requirements
The Lyric fireplaces mentioned in this manual have a
“zero clearance” fireplace, meaning you can build with
combustible material right up to the metal “zeroclearance” stand-offs on the fireplace. For
transportation purposes, the fireplace will arrive to the
jobsite with metal stand-offs flat against the fireplace.
All stand-offs on the fireplace must be fully extended
upon installation and remain extended after
installation. This ensures the safety and proper
functioning of the fireplace. Should you choose to
ignore this requirement, the warranty of the Lyric product will automatically void. The only exception
to this requirement applies to TV/artwork installation. Should you put a TV or artwork at the allowable
12” minimum above the fireplace viewing area, the front stand-off must be removed for this purpose
only. Please see TV/Artwork mounting requirements section for more details.
Lyric Installation Manual: Built-in Models, April 2019 9
Surrounding material is not allowed to transfer weight to the fireplace or be connected in any way to the
fireplace, with the exception of 5/8 Type X drywall (or its equivalent) in a flush installation. It may be
fastened to the frame with 1" self-tapping drywall screws 16'' on center, with a minimum of 2 ½” from
the metal lip. It must not transfer weight to the fireplace. No material is permitted to extend past the ½”
metal lip surrounding the glass viewing area. This area must be unobstructed so the screen heat barrier
and inside glass panel remain removable.
Non-combustible Material Definition
“Non-combustible material” is defined as material which will not ignite and burn. Such materials are those
consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750 ºC shall be considered non-combustible materials. An exception is made only
for fire rated 5/8” Type X drywall UL authorized or equivalent. For the purposes outlined in this manual,
5/8” Type X drywall may be used as a non-combustible material. Fireplace-specific construction boards
such as Promafour made by Promat are approved for use for added heat protection in place of 5/8” Type
X drywall. This is not a requirement. The use of these materials does not reduce any of the listed
clearances.
These materials are not being used for fire protection. They are used for high K and R value. Do not use
cement boards containing EPS beads.
Heat Release
A heat release is required for Lyric models listed in this manual. This allows for heat within the chase (the
cavity the fireplace is built in) to be released back into the living space, helping to keep the fireplace wall
cool. It must be located at the top of the fireplace chase and be placed within 6 inches (0-6”) of the
fireplace chase ceiling (aka draft stop). It can be located on the front, sides or back of the fireplace chase,
as long as it is being released into an interior space. The heat release cannot be vented outdoors as this
would expose the fireplace to outdoor elements and compromise the building envelope. A minimum air
space is required per series:
Series 90-110: Minimum 124 sq. in. of free air space
Series 140: Minimum 200 sq. in. of free air space
These air space values are the minimum required; they can always be increased. The heat release can be
in the form of (but not limited to) a ventilation grill (louver), gap, or reveal. If using a grill, make sure that
the net free air space allowed in the louvered area is equal or greater than the minimum number of square
inches required per fireplace (as listed above).
The interior area of the fireplace cavity (in square inches) can never be less than your required heat release
size. The area of the fireplace cavity is determined by multiplying the cavity width by the cavity depth. See
section titled, “Chase Area Minimums” for details.

Vertical Heat Release Designs
If your design cannot accommodate a horizontal heat release, a vertical heat release is acceptable.
Because heat rises, it will take longer for the heat to dissipate out of a vertically oriented heat release. To
compensate, a vertical heat release must be 30% larger than a horizontal heat release.
Series 40-110: Minimum 160 sq. in. of free air space for a vertical heat release
Series 140: Minimum 260 sq. in. of free air space for a vertical heat release
The heat release needs to start within 6 inches (0-6”) of the ceiling. The vertical heat release can be
applied using (but is not limited to) the following methods:
Front Split Vertical Heat Release
Front Split Vertical Heat Release (Front Elevation)
Lyric Installation Manual: Built-in Models, April 2019 13
Split Side Vertical Heat Release
Each half of the vertical heat release is put on each side of the fireplace cavity.
Left Side Vertical Heat Release (Side Elevation) Right Side Vertical Heat Release (Side Elevation)
Full Side Vertical Heat Release
The entire heat release is put on just one side of the fireplace cavity.
Full Side Vertical Heat Release (Right Elevation)
14 Lyric Installation Manual: Built-in Models, April 2019
Sprinkler Clearance to Heat Release
In a situation where a sprinkler head is in close proximity to the heat release, the detail shown in the
diagram below
must
be followed. The distance between the sprinkler head to the heat release opening
cannot be less than 60 inches (linear length) from any point of the heat release opening.
Chase Area Minimums
No part of the fireplace chase can have a smaller area than the required heat release size for your model
(in square inches). See the section “Heat Release” to find your model’s minimum required heat release
size. The size of the smallest part your chase should not be less than the size of your required heat
release.
Fireplace Legs
The Lyric models listed in this manual come standard with legs. These legs ensure that there is enough air
flow under the fireplace for proper operation. The legs cannot be removed. Leg height Lyric fireplaces is
8
1
4
⁄ ” from the bottom of the glass opening to the floor:
Floor/Platform
A Lyric fireplace can be set on wood, concrete, metal and other typical solid floor types. Lyric fireplaces come
with legs that position the fireplace above the floor or platform on which they are installed. To lower the
fireplace, it must be recessed into the floor. The legs cannot be removed, cut or adjusted.
Lyric Installation Manual: Built-in Models, April 2019 15
To raise the fireplace, build a platform to which the fireplace can be secured. Platform must be stable and able
to bear the full weight of the fireplace. Platform can be constructed out of plywood, concrete, metal or any
other solid materials. Material does not have to be non-combustible.
Securing the Fireplace
The fireplace has four total nailing flanges attached to the upper and lower sides of the front of the
fireplace body. Two seismic brackets on the top of the fireplace body are also supplied with the fireplace
for added security and stabilization. The nailing flanges and seismic brackets are to be attached into a
support structure upon installation. It is crucial to the finishing that the fireplace is stable, level and plumb.
Nailing Flanges Seismic Bracket
Access Panel
An access panel is not required by the manufacturer, but it may be required by the AHJ. An access panel
is highly recommended for all Lyric fireplaces mentioned in this manual. It allows for access to the
fireplace’s gas and electrical components for servicing.
Access Panel Size and Location Recommendations:
• Minimum of 10”x10” in size
• Located within 36” of the pilot (see “Gas Requirements and Setup” for diagram)
The size and location of the access panel may vary, but in all cases, it must allow the technician to
comfortably access and service the fireplace’s gas and electrical components. These components are
attached to the pilot on a flexible gas line and can be moved to any location within 36 inches of the pilot
(which is located at the center front of the burner).
For ease of access, move the fireplace’s gas and electrical components as close to the access panel as
possible. If there is any distance between the access panel and the gas and electrical components, it is
recommended to increase the size of the access panel accordingly. Prior to installation, fireplace
dealers/installers should work with their clients, project architects and/or interior designers to determine
the best size and location of their access panel.
16 Lyric Installation Manual: Built-in Models, April 2019
If an access panel cannot be incorporated, the alternative method of servicing the gas and electrical
components would be though the fireplace. This procedure requires removing the screen heat barrier,
internal glass panel, taking out the interior design media, and lifting the grill, burner and bottom pressure
release valve. This will increase service time and difficulty. An access panel is always preferred.
Fireplace dealers/installers are advised to consult with their clients regarding the advantages and
disadvantages of each service option.
Framing Requirements
The following sections show general framing requirements. Diagrams are shown with a flush wall application as
an example, but this is not the only type of application allowed. A recess of up to 4.5” over each glass opening
is allowed.
5/8” Type X Drywall Requirements
Framing must be covered completely with non-combustible material (as specified in the diagrams below) and
have the gaps sealed with a non-combustible fire sealant. We recommend using 5/8” Type X drywall (or
equivalent) with a level 1 finish (or better), but any building material that is equivalent to 5/8” Type X Drywall in
heat insulation (R-value and K-value). 5/8” Type X Drywall (or equivalent) must comply with ASTM C1396 ‐
Specification for Gypsum Board. Level 1 finish must be accordance with GA‐214 ‐ Recommended Levels of
Gypsum Board Finish.
Do not locate exposed 5/8” Type X Drywall joints directly above the fireplace. Plan to include weight of other
finish materials placed on the 5/8” Type X Drywall (or equivalent). If corner beads and other drywall trim are
required, use metal products where non‐combustible materials are required.
Fireplace-specific construction boards such as Promafour made by Promat are approved for use for added heat
protection. This is not a requirement.
The following diagrams show 5/8” Type Drywall (or equivalent) requirements for metal vs. wood framing.
Lyric Installation Manual: Built-in Models, April 2019 17
Wood Framing
5/8” Type X Drywall is required on the
interior (cladding the entire inner
cavity/chase) and exterior of the wood
framing. This provides heat protection for
both the combustible framing and your
finish material.
Wood Framing
Metal Framing
5/8” Type X Drywall is required on the exterior of the
metal framing only. This provides heat protection for
your finish material.
Metal Framing
NOTE: If you are putting a TV or artwork above the fireplace, you will need a layer of 5/8” Type X
Drywall (or equivalent) inside as well as outside your framing, regardless of framing material. See the TV
Detail section for more information.
18 Lyric Installation Manual: Built-in Models, April 2019
