NON-COMBUSTIBLE FACING INSTALLATION
Non-combustible board
shipped with unit.
Non-combustible board-faces and edges
MUST BE PRIMED.
Non-combustible board
shipped with unit.
Caution: The non-combustible board supplied with this unit can
be damaged if dropped or struck. Handle with care.
1. Using drywall screws - secure non combustible material
around unit, framing and top nailing strip every 6 inches.
Important Note: To avoid cracking the board - pre-drill holes prior to
securing to unit/ framing.
2. Wipe any debris/dust from the non combustible
material and drywall.
3. Prior to securing it is mandatory to prime the facing and edges using a quality
primer. This will ensure proper adhesion of both the tape and mud. The
supplied board is very porous.
Failure to follow this procedure will result in cracked seams.
4. Tape the seams using a mesh type tape.
5. Mud seams as normal. We recommend using a
product called Durabond high strength compound - for the first coat.
This product can be found at any hardware store.
Mud must be cured as per manufacturer’s recommendations.
6. Prime wall for a second time for proper adhesion of paint
7. Paint walls using a high quality paint which will withstand
the high temperatures being emitted from this appliance.
NON-COMBUSTIBLE REQUIREMENTS
* Installation of the Receiver must be completed before installing non-combustible facing.
All three pieces (top, 2 sides) are supplied to meet the non combustible requirements.
Calcium silicate board is a high - grade material
with cement, quartz, natural and selected
minerals as the main raw materials. It is widely
used for partitions and ceilings in buildings.
It is fire proof and earthquake proof.
If finishing the wall above the unit with materials
such as tile, brick, marble, etc. non-combustible
board available from the building supply store
can be used.

FRAMING & FINISHING
Note: When constructing the framed opening, please ensure there
is access to install the gas lines when the unit is installed.
2. For exterior walls, insulate the enclosure to the same degree as the
rest of the house, apply vapour barrier and drywall, as per local instal-
lation codes. (Do not insulate the replace itself.)
WARNING: Failure to insulate and add vapor barriers to the inside
of the exterior wall will result in operational and performance
problems including, but not limited to: excessive condensation
on glass doors, poor ame package, carbon, blue ames etc.
These are not product related issues.
3. The unit does not have to be completely enclosed in a chase. You
must maintain clearances from the vent to combustible materials: See
"Clearances" section. Combustible materials can be laid against the
side and back standoffs and the stove base.
4. Non-combustible material (ie. tile, slate, etc) may be brought up to and
overlap the unit (top and bottom) ensuring that the maximum thickness
does not go beyond the 3-1/4" as shown in the diagram below. The
faceplate will not be able to be mounted if nished material is beyond
3-1/4" .
1. Frame in the enclosure for the unit with framing material.
IMPORTANT: The framed opening must be of non-combustible
material.
IMPORTANT: 1/2" gap is required between the faceplate and the nished
wall when using 4 piece Faceplate (Part # 258-954, 258-957)
or Verona Glass Surround (Part # 256-951, 256-957)
1/2" required
between faceplate
+ finished wall
5. If material such as brick, stone, etc extends past the faceplate depth (3-1/4"),
when nishing around the faceplate, the minimum opening dimensions noted
below must be adhered to ensuring for the removal of the faceplate and for
the safe operation of this appliance.
NOTE: Spacing of 1" around the completed surround must be adhered to.

FRAMING & FINISHING
Important:
Determine the nailing strip position by determining the facing material being used.
Examples:
1/2" non-combustible wall board for clean nish = 2-3/4" adjustment.
1/2" non-combustible wall board + 1/2" tile = 1" of nished material
= 2-1/4" adjustment.
Note:
Depending on the material used for nishing, the nailing strips must be set ac-
cordingly so that the nished material is always at the 3-1/4" edge of the ange.

IMPORTANT
Regency Fireplace Products are designed, produced, tested and certified to the highest industry standards.
The finishing of the walls surrounding your Regency Horizon Fireplace is as critical as the installation itself.
The temperatures around linear gas fireplaces are typically higher than would be acceptable for combustible materials. Your Regency
Horizon Fireplace is no exception to this rule. Therefore, the units are specified with non-combustible required materials to specific
dimensions above and around the units. This is due to these areas reaching higher temperature levels than required/acceptable for a
combustible material. To obtain the best, most durable finish around your fireplace, this calls for a high level of care and attention to the
preparation and finish around this appliance, using only the highest quality materials, able to withstand the temperatures produced.
By following the installation instructions in the manual exactly, you will increase your chances of a damage free finish.
While every precaution is taken in providing the recommendations on preparation and finish, given the variations in paint quality, with
temperature limits and workmanship in application, Regency is unable to guarantee the life of the joint compounds, paint or any other
finish materials or workmanship applied to or used in any application surrounding the fireplace. This includes framing as well as finishing.
Over time natural convection from any fireplace can cause discoloration in the area directly above the appliance. Lower quality paints,
under-prepared finishes, poor applications, and any framing discrepancies or in the installation can cause this discoloration process to be
expedited.
Discoloration is not the responsibility of Regency Fireplace Products. This is out of the control of Regency Fireplace Products Ltd.,
therefore not covered under any part of the warranty policy.
While discoloration is not the responsibility of Regency Fireplace Products, we believe careful attention to the recommendations provided
here will result in an aesthetically pleasing result free of issues outlined above.
