To the New Owner:
Congratulations!
You are the owner of a state-of-the-art Gas Fireplace by REGENCY®. The HZ54E has been designed to provide you
with all the warmth and charm of a wood fireplace at the flick of a switch. The model HZ54E has been approved by
Warnock Hersey/Intertek for both safety and efficiency. As it also bears our own mark, it promises to provide you
with economy, comfort and security for many trouble free years to follow. Please take a moment now to acquaint
yourself with these instructions and the many features of your Regency® Fireplace.
On Demand Pilot Light (seven day safety timer)
Important information if using the appliance in CPI (continuous pilot mode) only.
This appliance is a ProFlame 1 system fitted with the “On Demand” Pilot, a safety feature which will shut down the gas valve com-
pletely by extinguishing the pilot light in the event of a continuous full seven days of inactivity.
This only applies if the CPI (continuous pilot) switch is in the “on” position.
Each time the main burner shuts down, manually or through the call from the thermostat, the seven day timer starts again.
The seven day inactivity timer is controlled within the circuit board. Therefore, if in CPI mode and when the pilot light is extinguished
after seven straight days of inactivity, the IPI/CPI rocker switch will remain in the “on” position. Therefore, all that is required to relight
the pilot would be to press the on/off button on the remote control transmitter from “on” to “off” and back to “on”. Once the pilot has
re-established operation will resume as normal. There is no requirement to do anything with the IPI/CPI rocker switch.
If the unit never goes as long as seven full days without a call for heat, the pilot will remain lit until it is manually shut-off.
If the unit is being operated in IPI (intermittent pilot) mode, neither the above instructions nor the seven day timer will apply.
See the instructions in this manual and on the Lighting Instructions plate on the appliance to light or re-light the pilot.

LOW BATTERY POWER DETECTION
Transmitter
The life span of the remote control batteries depends on various factors:
quality of the batteries used, the number of ignitions of the appliance,
the number of changes to the room thermostat set point, etc.
When the Transmitter batteries are low, a Battery Icon will appear on the
LCD display of the Transmitter (Fig. 22) before all battery power is lost.
When the batteries are replaced this Icon will disappear.
Figure 19
CPI/IPI Switch
This appliance comes equipped with a CPI/IPI switch.
The functions of both the CPI/IPI switch are as follows:
Continuous pilot (CPI) - A pilot that, once placed in operation, is intended to remain ignited
continuously until it is manually interrupted.
Intermittent pilot (IPI) - A pilot that is automatically ignited when an appliance is called on to
operate and which remains continuously ignited during each period of main burner operation. The
pilot is automatically extinguished when each main burner operating cycle is completed
The mode of the fireplace is easily changed from an intermittent pilot ignition system (IPI) to a
continuous pilot ignition system (CPI) by using the silver toggle switch located on the fireplace.
(See noted location of CPI/IPI Switch)
The benefits of having CPI are as follows:
-Keeps venting primed for trouble free start-up under colder weather conditions or inversions.
-Keeps the unit glass warm, which decreases the amount of condensation on start-up.
-Provides owners with flexibility to choose a traditional continuous pilot. (7 day/Pilot on Demand)
The primary benefit of having the IPI function is a significant savings on fuel as the pilot will only
run when there is a call for heat.
ENABLE / DISABLE functions on the Proflame I remote only.
1. Remove one battery from the remote.
2. Press and hold both the ON/OFF and the MODE button at the same time
3. Reinstall the battery (removed in Step 1) while still holding both buttons (keep holding both
buttons and once all batteries are installed then release the MODE button only).
4. The screen will show CFG.
5. Use the up or down arrow button to program out the function on the remote.
Note: You should never program out the fan (If installed) feature on the remote.
It is not possible to remove the thermostat mode on this remote control.

MUST BE PRIMED.
Non-combustible board
Caution: The non-combustible board 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, mud and
paint. 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.

cluding,but not limited to:excessive condensation on glass doors, poor flame package, carbon,blue flames 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) When finishing around the faceplate, if material such as brick, stone, etc. extend past the faceplate depth due to the finished material exceeding 3-1/8" -
the minimum opening dimensions noted below must 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
finishing around the unit. This is to ensure the removal of the faceplate
and for the safe operation of this appliance.

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 flat position and must be
folded into shape and attached - see diagram 1.
1) Remove the standoffs from the unit.
2) 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 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.
Note: These flue 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.
IMPORTANT NOTE
Framing depth measurement is noted with the
side nailing strips set as far forward on the
firebox as possible. The nailing strips can be
adjusted back up to 3-1/8” to allow for varying
thicknesses in non-combustible material & wall
finishes.
