FINISHING INFORMATION & PLANNING
NOTE: SÓLAS can only oer guidance as to the type of
materials that can be safely used during the installation
of your fireplace and cannot comment on, or be
responsible for, any finishing material’s propensity for
fading, flaking, discoloring, cracking, or chipping due to
improper installation and/or thermal expansion. Be sure
to consider a material’s propensity to “o-gas” when hot
as this may cause discomfort for the end user.
FINISHING SUGGESTIONS:
Standard gypsum board may be used beyond the perimeter
of the non-combustible zone however it is preferable not
to change materials to help avoid cracking. Ensure that all
compound, mortar, and/or silicone adhesives are rated for
high-temperature applications and have fully cured before
using the fireplace to help reduce the possibility of cracking
as a result of thermal expansion.
• Tile and Stone Veneer Products:
Install a minimum of ½" non-combustible cement board
then apply tile or stone with mortar following instructions
from the finishing material company. Pre-drill cement
board with oversized holes and do not over-tighten
screws to avoid cracking due to thermal expansion.
• Natural Stone, Marble or Granite Type Products:
Install a minimum of ½" non-combustible cement board
then apply tile or stone with mortar following instructions
from the finishing material company. Pre-drill cement
board with oversized holes and do not over-tighten
screws to avoid cracking due to thermal expansion.
NOTE: For a Minimal “Clean” look, we recommend using
materials that have been tested for specific high heat
applications and are designed not to crack or chip such
as Promat and Skamol products. Any other materials
used to achieve this same look might not perform as
intended and are likely to discolor, crack and/or chip.
Additional tips to help avoid cracking;
• Allow materials to dry thoroughly before finishing the wall.
• Always pre-drill cement board with oversized holes and
use screws with self-milling head.
• Always use tape over joints.
• Double up studs or use studs “on the flat” to add extra
support to the joint. Help control dierential movement by
applying adhesive on the backside of the wall board joints.
• Use multiple, thinner coats of joint compound and allow to
completely dry between coats.
• Ensure all framing materials are dry.
• Introduce heat gradually after finishing the wall to slowly
dry any excess moisture.
• Avoid notching tiles or cement board around corners of
window opening and instead provide a joint that intersects
the corner.
• Take guidance from your authorized fireplace dealer and
experienced installer.
Consult installation and operating instructions supplied
with your SÓLAS fireplace for complete instructions for the
installation and operation of the appliance.
NOTE: Prior to enclosing the wall cavity, test fire the fireplace to ensure it is fully operational.

INSTALLATION INFORMATION
Your SÓLAS fireplace is equipped with a Comfort
Blower to help eciently move heat into your living
space.
The Comfort Blower has 4 speed levels controlled
by the SÓLAS One-Touch remote. See bottom right
column of page 36 for details on remote operation.
In the event of a power outage, your fireplace will
continue to operate, but the Comfort Blower will not
function. Once power is restored you can use the
Comfort Blower.
We recommend using your Comfort Blower on speed
1 or 2 which will help move a sucient amount of
warm air from your fireplace into your heating zone
while remaining quiet. With the increased air speed
of levels 3 and 4, there will be a noticeable dierence
in sound.
We recommend during the annual service on your
fireplace Comfort Blower, use a vacuum and/or
compressed air to remove any dust, pet hair etc.
When servicing your fireplace, first shut o power
to it.
The Comfort Blower is located to the left of the
gas valve located under the air screen assembly.
(as shown in image below). To gain access to the
Comfort Blower please see page 26 first for
Screen Removal.
In the event your Comfort Blower needs replacing, a
licensed service technician can remove the Comfort
Blower by removing the (2) ⁄-20 nuts with a ⁄"

The SÓLAS TWENTY6 Slim-Line Built-In Gas
Fireplace has been tested and listed for installation
with 4” X 6 ⁄” Simpson DuraVent GS/Pro®, Selkirk
Direct-Temp®, Security Secure Vent™, AmeriVent
Direct™, Metal Fab DirectVent 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
page 19. 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:
• For venting configurations that include no vertical
rise, a total horizontal equivalent vent run of up to
30 inches is allowed (when using a 45° elbow, 18
inches horizontal equivalent must be included).
However, if your installation has room to add a
vertical pipe section, we suggest adding at least
one foot of vertical rise to the system.
• For venting configurations that include vertical
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 total venting may not exceed 20 feet of
vertical rise and/or 10 feet horizontal run. Refer to
the venting charts starting on pages 20 & 21 for
specific details while you plan your installation.
Note: The number of elbows impacts the
maximum allowable horizontal vent run.
• Many installations will involve venting directly
through standard 2 X 4 or 2 X 6 construction
exterior wall to a horizontal vent termination
(cap). The vent starter pipe has been designed
to accommodate those two common installations
without the use of any additional venting
components other than a standard horizontal cap.
See the chart on page 19 for a list of approved vent
caps.
• A special corner installation kit (Part Number
CK-26-1) is also available that will allow the
TWENTY6 fireplace to be mounted in a corner
without constructing a 45° partition wall. This kit
is available from your SÓLAS dealer and has its
own installation instructions. Please refer to those
instructions for specific details regarding the
installation using the kit.
• If the 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 30", one
or more elbows will be required to allow addition
of the required vertical venting to the installation.
When vertical venting is required, the fireplace
venting may be terminated with either a vertical or
horizontal vent cap depending on the specifics of
the installation. Refer to the venting charts starting
on pages 20 & 21 for specific venting requirements
and see the chart on page 19 for a list of approved
vent caps before you plan your installation.
• There should be a 1 ⁄" overlap of the vent and
combustion air tubes, when telescopic joints are
used.
• A minimum clear space of 1 ⁄" must be maintained
around the vent pipe where it penetrates the first
combustible wall adjacent to 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). The special vent pipe
heat shields that are provided with the TWENTY6
must also be installed in the first wall adjacent to
the fire-place. A minimum clear space of 1 ⁄" must
also be maintained where the vent pipe penetrates
any other interior wall, exterior wall, ceiling or roof.
• The TWENTY6 may also be installed in front of an
exiting fireplace opening utilizing special co-linear
venting components available from the venting
manufacturers. These systems split and then
recombine the co-axial air and exhaust and allow
the use of flexible venting. This makes it easier
to run the venting through the narrow fireplace
damper opening to the top of the chimney. Refer
to the vent manufacturers’ instructions. Use the
vertical venting column (0 feet Horizontal Run)
in the venting charts to determine the required
restrictor settings depending on the height of
chimney.
VENTING

solasfires.com 19
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 25 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 aect the performance or appearance of the fire. The
TWENTY6 fireplace includes air and exhaust restrictors
that are used to balance the draft in the fireplace to the
optimal level for installations where excessive draft might
occur. The venting charts on pages 20 and 21 provide
an easy means for determining whether your specific
installation requires inlet air or exhaust restrictors or both.
To make the determination about whether air or exhaust
restrictors are needed, a venting chart worksheet is
provided on page 22. Follow the instructions and fill in the
worksheet for your particular installation. This will allow
you to determine the recommended restrictor settings
for your exact installation. Although this might appear to
be a complicated process at first glance, it is really quite
straight-forward and the result will be a fire that looks and
performs as intended. Several examples of worksheet
calculations are shown on page 23 to help guide you.
Please be sure to note that:
1. There are separate venting charts for Natural Gas and
LP Gas. Refer to the appropriate chart for your fuel type
to determine your specific restrictor requirements. The
settings in the charts have been deter-mined based on
extensive testing.
2. Determine the total vertical vent rise and total
horizontal vent run for your installation. All measure-
ments are made from the center of the vent opening in
the back of the fireplace.
3. If your fireplace will not be venting directly though an
outside wall to a horizontal termination or if more than
30" of horizontal vent run is required, some vertical
vent rise will be required for the fireplace to function
and vent properly. Elbows will also be required for
those installations. However, installations are limited
to a maximum of four 90° elbows (or 45° elbow
equivalents).
4. Note: Two 45° elbows equal one 90° elbow.
5. The recommended restrictor settings in the venting
charts allow up to two 90° elbows (or 45° elbow
equivalents) to be used without aecting the restrictor
settings. Additional elbows will require that you
calculate a new equivalent horizontal run for your
installation to account for the additional flow re-
sistance caused by the extra elbows. For the purposes
of calculating the equivalent horizontal vent run, each
additional 90° elbow is equivalent to three feet of
horizontal vent run and each additional 45° elbow is
equivalent to 1.5 feet of horizontal vent run. The total
horizontal vent run including elbow equivalents can
not exceed 10 feet.
6. The maximum vertical vent rise can not exceed 20 feet.
7. There are two exhaust restrictors that are provided
with your fireplace. They are labeled “A” and “B”. The A
restrictor provides less exhaust restriction than B.
8. An air restrictor plate is also provided with your
fireplace. It is a ring with bendable tabs that can be
set to adjust the amount of restriction in the air supply
system. Once the appropriate number tabs are bent
open (in accordance with the requirements for your
installation), the plate is inserted between the fireplace
and the vent starter pipe.
