HEATWAVE
DUCT SYSTEM
OPTIONAL KIT #946-556
The HeatWave Air Duct Kit increases the
effectiveness of your replace by dispersing warm
air from the replace to remote locations in the same
room or other rooms in your home.
Up to two kits may be installed on the replace.
Please Note: Only 1 HeatWave kit may be oper-
ated at one time. This includes the internal blower
option as well.
OPTIONAL
HEAT RELEASE KIT
#946-570
The Heat Release Kit expels warm air from the
replace to the outside of the building, allowing
the replace to be operated with less heat entering
the room. The kit may be used on either the left
or right side.
The HeatWave Duct Kit has different
clearance and framing requirements, check
the HeatWave manual for details.

If finishing the wall above the unit with paint -
the non-combustible board (shipped separately
from the unit) should be installed. Facing board
must be ordered when ordering the unit.
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.
Note: Calcium Silicate is 1/2" thick.
Caution: This non-combustible board can be damaged if
dropped or struck. Handle with care.

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.
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.

 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.
 When nishing around the faceplate, if material such as brick, stone, etc. extend past the faceplate depth due to the nished material exceeding 3-1/8" -
the minimum opening dimensions noted below  be adhered to, this is to ensure removal of the faceplate.
For material such as brick, stone, etc that extends 3-1/8" or less , the
minimum opening dimensions noted below must be adhered to when
nishing around the unit. This is to ensure the removal of the faceplate
and for the safe operation of this appliance.

Nailing Strips
Shipping brackets -

NAILING STRIPS
The nailing strips come attached to the unit. There is 1 plate on each side,
that can be folded out as required. The side nailing strips are secured to the
framing.
UNIT ASSEMBLY
PRIOR TO
INSTALLATION
The Top Standoff/ Nailing Strip, side nailing strips and standoffs must be
correctly positioned and attached to the unit before sliding the unit into position.
STANDOFF ASSEMBLY
The top, side and rear standoffs are shipped in a at position and must be
folded into shape and attached - see diagram 1.
 Remove the standoffs from the unit.
 Take each standoff and bend into the correct shape. Bend up at the bend
lines until the screw holes in the standoff and the pre-punched screw holes
on the unit line up.
VENTING INTRODUCTION
The HZ54E uses the "balanced ue" 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.

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.
IMPORTANT NOTE
Framing depth measurement is noted with the
side nailing strips set as far forward on the
rebox as possible. The nailing strips can be
adjusted back up to 3-1/8” to allow for varying
thicknesses in non-combustible material & wall
