INSTALLATIONFRAMING & FINISHING
1) Frame in the enclosure for the unit with framing material.
IMPORTANT: The framed opening must be of non-combustible
material.
Note: When constructing the framed opening, please ensure thereis access to install the gas lines when the unit is installed.

5) If material such as brick, stone, etc extends past the faceplate depth (1-1/2"),
when finishing around the faceplate, the minimum opening dimensions noted
below must be adhered to ensuring for the removal of the faceplate and forthe safe operation of this appliance.

2) For exterior walls, insulate the enclosure to the same degree as therest of the house, apply vapour barrier and drywall, as per local installation codes. (Do not insulate the fireplace itself.)
WARNING: Failure to insulate and add vapor barriers to the insideof the exterior wall will result in operational and performance
problems including, 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 theside and back standoffs and the stove base.
4) Non-combustible material (ie. tile, slate, etc) may be brought up to andoverlap the unit (top and bottom) ensuring that the maximum thickness
does not go beyond the 1-1/2" as shown in the diagram below. The
faceplate will not be able to be mounted if finished material is beyond
1-1/2".

6) For material such as brick, stone, etc that extends less than 1-1/2" , theminimum opening dimensions noted below must be adhered, when finishing around the faceplate. This is to ensure the removal of the faceplate andfor the safe operation of this appliance.

HZ42E Regency Horizon™ Gas Fireplace

INSTALLATIONVENTING INTRODUCTION
The HZ42E 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 fuelor gas burning appliance. Each direct vent gas appliance must use it's own separate vent system. Common vent systems are prohibited.

VENTING ARRANGEMENT FOR HORIZONTAL TERMINATIONS
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 90o (two 45o elbows equal one 90o elbow). (Not including
the starting 45o elbow at the flue collar when using rigid venting.)
Note: Must use optional rigid pipe adapter (Part# 510-994) when using Rigid Pipe Venting Systems.

10" x 10"Install the vent system according to the
manufacturer's instructions included with thecomponents.
1) Set the unit in its desired location. Check todetermine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust thelocation of the unit. Rough in the gas preferablyon the right side of the unit and the electrical(junction block is on the left side) on the left.
2) Direct Vent pipe and fittings are designed withspecial twist-lock connections to connect theventing system to the appliance flue outlet. A
twist-lock appliance adaptor is required.
3) In conjunction with the Approved Vent system,
install the adaptor after the unit is set in its
desired location. Put a bead of high temperaturesilicone inside the outer section of the adapter
and a bead of Mill Pack on the inner collar. Slip
the adapter over the existing inner and outerflue collar. Fasten to the outer collar only withthe 3 supplied screws (drilling pilot holes will
make this easier).
4) Level the fireplace and fasten it to the framing
using nails or screws through the top and side
nailing strips.

Note: If installing termination on a vinyl siding
covered wall, a vinyl siding standoff or
furring strips must be used to ensurethat the termination is not recessed into
the siding.

Horizontal runs of vent must be supported every
3 feet (0.9meter). Wall straps are available forthis purpose.

6) Mark the wall for a square hole.-see chart to left
for size. The center of the square hole should line
up with the center-line of the horizontal pipe. Cutand frame the square hole in the exterior wall
where the vent will be terminated. See diagram
2 for center line requirements.
If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole isacceptable.
Note:a) The horizontal run of vent must be level, or
have a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow thevent to run downward. This could cause
high temperatures and may present thepossibility of a fire.
b) The location of the horizontal vent termination
on an exterior wall must meet all local andnational building codes, and must not be
blocked or obstructed. See "Exterior Vent
Termination Locations" section for moredetails.

Diagram 5
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
8) Before connecting the horizontal run of vent pipe
to the vent termination, slide the Wall Thimble
over the vent pipe. The wall thimble is required
for all horizontal terminations.
9) Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into thevent cap assembly. It is important that the ventpipe extends into the vent cap sufficient distanceso as to result in a minimum pipe overlap of
1-1/4 inches (32mm). Secure the connection
between the vent pipe and the vent cap.
10) Install wall thimble in the center of the framedhole and attach with wood screws (Diagram 7).

IMPORTANT: Do not locate termination hood
where excessive snow or ice buildup may
occur. Be sure to check vent termination
area after snow falls, and clear to prevent
accidental blockage of venting system. Whenusing snow blowers, make sure snow is notdirected towards vent termination area.

2) Level the fireplace and fasten it to the framing
using nails or screws through the nailing strips.
3) Assemble the vent assembly by applying Mill
Pac to the inner flue collar of the terminationand slipping the inner flex liner over it at least

NOTE: For best results and optimum performance with each approved venting system, it
is highly recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe connection. Failure to do so may result in drafting or
performance issues not covered under warranty.
Silicone (red RTV) is optional.

5) Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The holeshould be of sufficient size to meet the minimum
requirements for clearance to combustiblesof 1-1/2". Slip the flashing under the shingles(shingles should overlap half the flashing) asper Diagram 3.

3) A Firestop spacer must be installed in thefloor or ceiling of every level. To install theFirestop spacer in a flat ceiling or wall, cut
a 10 inch square hole. Frame the hole asshown in Diagram 2 and install the firestop.

INSTALLATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities and the CAN/CGA B149 installationcode.
For USA installations follow local codes and/or thecurrent National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so thatgas lines can be easily disconnected for servicing.
Flare nuts for copper lines and flex connectors
are usually considered to meet this requirement.
NOTE: A shutoff / dante valve should be supplied in or near the unit (or as per local codes)
for ease of servicing this appliance.
IMPORTANT: Always check for gas leaks witha soap and water solution or gas leak detector.
Do not use open flame for leak testing.

The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-off
valve during any pressure testing of the gas supply
piping system at test pressures equal to or lessthan 1/2 psig. (3.45 kPa). Disconnect piping fromvalve at pressures over 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked at
the pressure test point.

Note: To properly check gas pressure, both
inlet and manifold pressures should bechecked using the valve pressure portson the valve.

561) Make sure the valve is in the "OFF" position.
2) Loosen the "IN" and/or "OUT" pressure tap(s),turning counterclockwise with a
1/8" wide flat screwdriver.
3) Attach manometer to "IN" and/or "OUT" pressuretap(s) using a 5/16" ID hose.
4) Light the pilot and turn the valve to "ON" position.
5) The pressure check should be carried out withthe unit burning and the setting should be within
the limits specified on the safety label.
6) When finished reading manometer, turn off thegas valve, disconnect the hose and tighten thescrew (clockwise) with a 1/8" flat screwdriver.
Note: Screw should be snug, but do not overtighten.

INSTALLATIONWIRING DIAGRAMThis heater does not require a 120V A.C. supply for operation. In case of a power failure, the burner switch and the optional remote control/thermostat willcontinue to operate. However, a 120V A.C. power supply is needed for the fan/blower operation.
(Do not cut the ground terminal off under any circumstances.)
NOTE: Even if the fan is not purchased with the unit, it is still a good idea to bring power to the receptacle box (provided with the unit) in case thefan is installed at a later date.

Note: 4 AA batteries must be installed to operate
the burner switch.
Do not use a 9 volt battery.
IMPORTANT: If the optional remote control is used, the AA batteries normally installed into the battery holder must be removed. The AA batteries in thereceiver now operate the unit. Having AA batteries in both the battery holder and receiver will damage the gas valve.

OPERATING INSTRUCTIONSOPERATING
INSTRUCTIONSLIGHTING
PROCEDURE

1) Read and understand these instructions
before operating this appliance.

IMPORTANT
To ignite or reignite the pilot, youmust first remove the glass door.

2) Check to see that all wiring is correct andenclosed to prevent possible shock.
3) Check to ensure there are no gas leaks.

1) Press and release on ON/OFF button once
on the remote control or ON/OFF switch.

4) Make sure the glass in the glass door frame
is properly positioned. Never operate theappliance with the glass removed.

2) After approximately 4 seconds the spark
ignition system will spark for 60 seconds tolight the main burner.

5) Verify that the venting and cap areunobstructed.

3) The unit will turn on.

6) The unit should never be turned off, and on
again without a minimum of a 60 second
wait.

FIRST FIRE
The FIRST FIRE in your heater is part of thepaint curing process. To ensure the paint is properly cured, it is recommended you burn yourfireplace for at least four (4) hours the first time.
When first operated, the unit will release anodour caused by the curing of the paint and theburning off of any oils remaining from manufacturing. Smoke detectors in the house may go off
at this time. Open a few windows to ventilate
the room for a couple of hours. The glass may
require cleaning.
NOTE: When the glass is cold and the applianceis lit, it may cause condensation and fog
the glass. This condensation is normal
and will disappear in a few minutes as
the glass heats up.

DO NOT ATTEMPT TO CLEAN THE
GLASS WHILE IT IS STILL HOT!

DO NOT BURN THE UNIT WITHOUT THE
GLASS DOOR IN PLACE.

Note: The first try for ignition will last approximately 60 seconds. If there is no flame ignition(rectification) the board will stop sparking for
approximately 35 seconds. After wait time
, the board will start second try for ignitionby sparking for approximately 60 seconds .
If there is still no positive ignition the board
will go into lock out.
The system will need to be reset as follows:a) Turn the system off using ON/OFF switch
or press ON/OFF button - if using optional
remote.
b) After approximately 2 seconds turn on ON/
OFF switch or press ON/OFF button if using
optional remote.
c) Repeat step 2.

NORMAL OPERATINGSOUNDS OFGAS APPLIANCES
It is possible that you will hear some sounds fromyour gas appliance. This is perfectly normal due tothe fact that there are various gauges and typesof steel used within your appliance. Listed below
are some examples. All are normal operating
sounds and should not be considered as defects
in your appliance.
Burner Tray:
The burner tray is positioned directly under theburner and is made of a different gauge material
from the rest of the firebox and body. Therefore,
the varying thicknesses of steel will expand andcontract at slightly different rates which can cause"ticking" and "cracking" sounds. You should also
be aware that as there are temperature changes
within the unit these sounds will likely re-occur.
Again, this is normal for steel fireboxes.
Pilot Flame:
While the pilot flame is on it can make a veryslight "whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, adull clicking sound may be audible, this is normal
operation of a gas regulator or valve.
Unit Body/Firebox:
Different types and thicknesses of steel will
expand and contract at different rates resulting
in some "cracking" and "ticking" sounds will beheard throughout the cycling process.

SHUTDOWNPROCEDURE
1) Turn the wall mounted switch or remote to
the "OFF" position.
2) Press "OFF" on the remote control.
3) Turn the gas control knob to the "OFF" position to turn off the pilot.

During the first few fires, a white film
may develop on the glass front as part ofthe curing process. The glass should becleaned after the unit has cooled downor the film will bake on and become very
difficult to remove. Use a non-abrasive
cleaner and DO NOT ATTEMPT TO CLEAN
THE GLASS WHILE IT IS HOT.

LIGHTING INSTRUCTIONSs1) Turn on ON/OFF switch
2) After approximately 4 seconds the spark ignition system will spark for 60 seconds to light the mainburner.
3) The unit will turn on.
Note: The first attempt to ignition will last approximately 60 seconds. If there is no flame ignition (rectification) the board will stop sparking for approximately 35 seconds. After this wait time, the board will start a
second try for ignition by sparking for approximately 60 seconds. If there is still no positive ignition after thesecond attempt the board will go into lock out.
The system will need to be reset as follows (after going into lock out mode):a) Wait 5 minutes - turn the system off using ON/OFF switch.
b) After approximately 2 seconds turn on ON/OFF switch or press ON/OFF button if using optional

le brûleur principal.
3) Les flammes s’allumeront.
Remarque : Au premier allumage, le système tente d’allumer les flammes pendant 60 secondes. Si l’essai est
infructueux, le système fait une pause de 35 secondes. C’est ce qu'on appelle l'étape de rectification. Ce délaiécoulé, le système tente à nouveau d'allumer les flammes en produisant des étincelles pendant 60 secondes.
Si les flammes ne s’allument toujours pas, le système se met en mode verrouillage.
Il faut alors le réinitialiser en suivant les étapes ci-dessous (pour le déverrouiller) :a) Attendre 5 minutes et éteindre l’appareil en réglant l’interrupteur à la position « OFF »;b) Attendre 2 secondes et rallumer le système à l’aide de l’interrupteur ou de la télécommande.
