FRAMING & FINISHING
4. Frame in the enclosure for the unit with framing material.
Note: When constructing the framed opening, please ensure there is access to install the gas lines when the unit is installed.
5. For exterior walls, insulate the enclosure to the same degree as the rest of the house; apply vapour barrier and drywall, as per local installation 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.
6. 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.
7. Tile Finish Option 1: Drywall may be installed onto the unit as shown below to create a surface to apply finishing materials such as tile, slate, etc.
Drywall cannot extend beyond the metal surface of the unit.
8. Tile Finish Option 2: If applying a non-combustible finishing material (tile,slate,etc) the material can be installed directly onto the metal surface (clean
front) of the unit in the area shown below.

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 outwith 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.

IMPORTANT FINISHING DETAIL NOTE:
Before placing unit into nal position - it is important to know the
total thickness / height of nished hearth (tile, carpet, etc.) The base
of the replace, 4 sided faceplate or mantel should be level or higher
than the nished hearth height.
NOTE: The 3-1/2" x 34-9/16" non combustible material supplied with this unit can be replaced if trying to achieve a clean finish. A large piece of non com-
bustible material (ie. 4' x 8' x 1/2") can be used to eliminate taped seams on or near unit.

VENTING INTRODUCTION
The HZ33CE uses the "balanced flue" technology Co-Axial system. The inner liner vents products of combustion to the outside while the outer liner
draws outside combustion air into the combustion chamber thereby eliminating the need to use heated room air for combustion and losing warm room
air up the chimney.
There are several vent systems approved for use with the HZ33CE: (see following "Venting" Sections for more details on approved vent systems).
Note: These ue pipes must not be connected to any other appliance.
The gas appliance and vent system must be vented directly to the outside of the building, and never be attached to a chimney serving a separate solid
fuel or gas burning appliance. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited. (See "Rigid
Pipe Venting System" for more details and exceptions).
NOTE: Ensure compliance with the outside vent terminal location before cutting hole as both dimensions must be met.

REGENCY®DIRECT VENT FLEX SYSTEM
Horizontal Terminations Only
This venting system, in combination with the HZ33CE-10 Direct Vent Gas Fireplace, have been tested and listed as a direct vent heater system by Warnock Hersey.
The location of the termination cap must conform to the requirements in the "Exterior Vent Terminal Locations" Section .
Regency® Direct Vent Flex Termination Kit (Part # 946-513. includes all the parts needed to install the HZ33CE with a maximum run of 2 feet. If
installing the HZ33CE-10 with a continuous vent length of more than 2 ft (.6m) to a maximum of 10 ft. (3.0m) use Kit # 946-515 (4 ft) or 946-516 (10 ft) or
see "Rigid Pipe Venting Systems" Section for alternate venting arrangements.

1 45o Elbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness
(see chart)
For siding other than vinyl, furring strips may
be used, instead of the vinyl siding standoff, to
create a level surface to mount the vent terminal.
The Terminal must not be recessed into siding.
If a Vinyl Siding Standoff is required (it must
be used with vinyl siding), measure to outside
surface of wall without siding and add 2 inches.
This product has been evaluated by Intertek
for using a Rigid Pipe Adaptor in conjunction
with Duravent Direct-Vent , Selkirk Direct-Temp,
Ameri Vent Direct venting and Security Secure
Vent systems. Use of these systems with the
Rigid Pipe adaptor is deemed acceptable
and does not affect the Intertek WHI listing of
components.
WARNING:
Do not combine venting components from
different venting systems.
Exception: However, use of the the AstroCapTM
and FPI Riser is acceptable with all systems.
When using Rigid Vent other than
Simpson Dura-Vent, 3 screws must be
used to secure rigid pipe to adaptor.
