ring correctly and operation fully explained to
customer.
This includes:
1) Clocking the appliance to ensure the correct
ring rate (rate noted on label) after burning
appliance for 15 minutes.
2) If required, adjusting the primary air to ensure
that the ame does not carbon. First allow
the unit to burn for 15-20 min. to stabilize.
CAUTION: Any alteration to the product that
causes sooting or carboning or that results in
damage is not the responsibility of the manu-
facturer.
The clearances listed below are MINIMUM
distances. Measure the clearance to both
the appliance and the chimney connector.
(The farthest distance is correct if the two
clearances do not coincide.) For example,
if the appliance is set as indicated in one of
the gures but the connector is too close,
move the stove until the correct clearance
to the connector is obtained.
This unit can be installed on a solid com-
bustible surface like a wood oor. This unit
can also be installed directly on carpeting or
vinyl when the bottom pedestal cover plate
(provided with unit) is installed.
This appliance may be installed only with
the clearances as shown in the situations
pictured. Do not combine clearances from
one type of installation with another in order

side doors to the unit.
2) Attach the long side doors to the stove body
using the screws provided (4 per door).
OPTIONAL OUTSIDE
AIR
Outside air for combustion can be brought in
either through the bottom of the pedestal or
through the rear plate of the pedestal. Rear View
DRAFT HOOD
This heater has a draft hood built in. It must
not be altered, obstructed, or blocked in any
way, and the unit must be installed so that the
draft hood is in the same atmospheric pressure
zone as the combustion air inlet to the burner.
This heater must be properly connected to a
venting system. This heater is equipped with a
vent safety shuto󰀨 system.
For both bottom and rear "outside air" the Ped-
estal Cover Plate must be installed. Loosen the
4 screws on the rear of the pedestal and slide
the cover plate over them. Slide the plate to the
left to center it and tighten down the 4 screws.
Outside Air Through
Pedestal Bottom
Once you have properly marked the position of
your unit as outlined in "General Information"
and "Clearances to Combustibles", cut a prop-
erly sized hole though the oor directly under
your pedestal base to the outside. Pipe fresh
air into the pedestal area by using appropriate
metallic duct pipe with a mesh grill at the outside
termination. Do not remove the knockout.
WARNING: Operation of this heater when
not connected to a properly installed and
maintained venting system or tampering
with the vent safety shut-o󰀨 system can
result in carbon monoxide (CO) poisoning
and possible death.
HIGH ELEVATION
The U43 is approved in Canada for altitude
2000 ft. to 4500 ft. (CAN/CGA-2.17-M91) with
the orice kit (Part # 591-975). For Natural
Gas installations above 4500 ft. follow current
CAN/CGA-B149.1.
In U.S.A., for installations above 2000 ft. refer
to current ANSI Z223.1 Sc8-8.1.2a appendix F,
for resizing orice.
U28: OPTIONAL
LONG SIDE DOOR
INSTALLATION
INSTALLATION
VENTING
This heater is a vented appliance and must be
connected to a chimney/ue in accordance with
the installation codes.
Note: The rear pedestal cover plate is
only required when outside air is
being used. If using room air for
combustion, remove this plate from
the back of the pedestal.
For your safety this heater is equipped with a
vent safety switch designed to sense incorrect
venting and react by shutting down the gas
supply. This thermally actuated switch is located
within the draft hood and will detect either a
blocked chimney or backdraft condition where
the chimney ow has reversed. If this switch
shuts the unit down, it indicates a drafting
problem that must be identied and rectied
without delay - the thermally activated switch
must never be bypassed or disconnected as
a hazardous or deadly condition can result.
Venting Requirements
A four inch diameter vent is required. B-Vent,
Class A or Masonry with an approved liner
are all acceptable. For cosmetic or aesthetic
purposes 6" outer vent can be used as long as
an approved inner vent is installed. Fasten but
do not penetrate the inner sleeve of the B-Vent
when tightening the screw.
Follow all venting manufacturer’s requirements
and local building codes. In cold climates,
we recommend the use of insulated B-vent,
chase, and liners. For altitudes above 2000
ft. we recommend that a minimum ue height
of 12 ft. is used.
Flue Mounting Bracket
Attach the ue mounting bracket with the en-
closed screw as shown in the diagram.
Outside Air Through
Rear of Pedestal
Remove the blanking plate from the rear of the
pedestal cover plate and bend the two tabs out
90 degrees. Pipe fresh air into the pedestal
area by using duct pipe with a mesh grill at
the outside termination. Attach the pipe to the
tabs with screws.

GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-o󰀨 valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig. (3.45
kPa). Disconnect piping from valve at pressures
over 1/2 psig (14" w.c.).
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 be checked using the valve
pressure ports on the valve.

TEST FOR FLUE
SPILLAGE
A "spillage" test must be made before the
installed unit is left with the customer. Follow
the procedure below:
1) Start all exhaust fans in the home and any
other gas appliances. Then close all doors
and windows.
2) Light the unit and set controls to maximum.
3) After ve minutes, test that there is a "pull"
on the ue by placing a smoke match,
cigarette or similar device which gives o󰀨
smoke, on the edge of the draft hood. See
diagrams.
The thermally activated safety
switch must be manually reset
before rst startup.
U28: LOUVER
INSTALLATION
1) Attach the top & bottom louvers to the side
stove panel using 2 screws per side.
Diagram 1
FRONT DOOR
INSTALLATION
(packaged separately)
1) Open the two side panels.
2) Slide the door onto the two hinge pins making
sure the two pieces are ush together. See
diagram 1.
3) Close the door. The latch plate must be
centered around the alignment pin. See
diagram 2. If the latch plate interferes with
the corner of the stove you may want to
angle the plate slightly so the door closes
easier.
4) The latches should already be at the proper
setting. If they are too hard or too easy
to close, you may want to adjust them by
loosening the latch catch. See diagram 3.
Diagram 2 - U43

INSTALLATION
5) Remove the blue plastic protective coating
from the glass.
6) Test the seal around the door by placing
a piece of paper between the unit and the
door, close the door and try to pull the paper
out. If it slips out easily, then the door is not
properly sealed. Tighten or loosen the latch.
See diagram 3.
Note: The door latch may require adjust-
ment as the door gasket material
compresses after a few res and
after glass replacement. Turn the
latch catch inward or outward to
loosen or tighten.
The smoke should
be drawn into the
draft hood. If the
smoke is not drawn
into the draft hood,
turn the unit o󰀨 and
check for the cause
of lack of draft.
Note: If the ue is blocked or has a strong
reverse ow, the thermally actuated safety
switch mounted in the draft hood will auto-
matically shut o󰀨 the gas supply within about
10 minutes. If the heater turns o󰀨 because
of this during the spillage test, check for the
cause of the lack of draft.

paint curing process. To ensure that the paint
is properly cured, it is recommended that you
burn your replace for at least four (4) hours the
rst time you use it with the fan on. When rst
operated, the unit will release an odour caused
by the curing of the paint and the burning o󰀨 of
any oils remaining from manufacturing. Smoke
detectors in the house may go o󰀨 at this time.
Open a few windows to ventilate the room for a
couple of hours. The glass may require cleaning.

OPERATING INSTRUCTIONS

Regency U28-2/U43-3 ULTIMATE Freestanding Gas Heater 17
NORMAL OPERATING
SOUNDS OF
GAS APPLIANCES
It is possible that you will hear some sounds
from your gas appliance. This is perfectly normal
due to the fact that there are various gauges
and types of 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.
Blower:
Regency gas appliances use high tech blowers
to push heated air farther into the room. It is not
unusual for the fan to make a "whirring" sound
when ON. This sound will increase or decrease
in volume depending on the speed setting of
your fan speed control.
Burner Tray:
The burner tray is positioned directly under the
burner tube(s) and logs and is made of a di󰀨er-
ent gauge material from the rest of the rebox
and body. Therefore, the varying thicknesses of
steel will expand and contract at slightly di󰀨erent
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 reboxes.
Blower Thermodisc:
When this thermally activated switch turns ON
it will create a small "clicking" sound. This is the
switch contacts closing and is normal.
Pilot Flame:
While the pilot ame is on it can make a very
slight "whisper" sound.
Gas Control Valve:
As the gas control valve turns ON and OFF, a
dull clicking sound may be audible, this is normal
operation of a gas regulator or valve.
Unit Body/Firebox:
Di󰀨erent types and thicknesses of steel will
expand and contract at di󰀨erent rates resulting
in some "cracking" and "ticking" sounds will be
heard throughout the cycling process.
AERATION
ADJUSTMENT
The burner aeration is factory set but may need
adjusting due to either the local gas supply or
altitude.
U43-NG3 Natural Gas: 3/16" open
U43-LP3 Propane: 1/2" open
U28-NG2 Natural Gas 1/8" open
U28-LP2 Propane 3/8" open
The aeration adjustment gears are located on the
right side of the burner box and can be accessed
from the side or from the front when the louvers
are removed.
To adjust the aeration: use the allen key to turn
the turning gear which will adjust the air shutter.
Open the air shutter for a blue ame or close it for
a yellower ame. This adjustment is performed
by a qualied installer. The factory setting should
be su󰀩cient for most installations.

OPERATING INSTRUCTIONS
PILOT ADJUSTMENT
Periodically check the pilot ames. Correct
ame pattern has three strong blue ames: 1
owing around the thermopile and 1 around the
thermocouple, and 1 owing across the rear of
the burner (it does not have to be touching the
burner).
Note: If you have an incorrect ame pat-
tern, contact your Regency dealer
for further instructions.
Incorrect ame pattern will have small, probably
yellow ames, not coming into proper contact
with the rear of the burner or thermopile.
Clockwise to open,
counter-clockwise to close.
Caution: Carbon will be produced if the air
shutter is closed too much.
Note: Any damage due to carboning re-
sulting from improperly setting the
aeration controls is NOT covered
under warranty.

MAINTENANCE
INSTRUCTIONS
1) Always shut the valve o󰀨 before cleaning.
For relighting, refer to lighting instructions.
Keep the burner and control compartment
clean by brushing and vacuuming at least
once a year. When cleaning the logs, use
a soft clean brush as the logs are fragile
and easily damaged.
2) Clean glass (never when unit is hot), appli-
ance, louvers, and door with a damp cloth.
Never use an abrasive cleaner. The gold
louvers (and optional gold door) may be
scratched if abrasives are used to clean
them.
The heater is nished in a heat resistant
paint and should only be renished with
heat resistant paint (not with wall paint).
Regency uses StoveBright Paint - Metallic
Black #6309.
3) Make a periodic check of burner for proper
position and condition. Visually check the
ame of the burner periodically, making sure
the ames are steady; not lifting or oating.
If there is a problem, call a qualied service
person.
4) The appliance and venting system must be
inspected before use, and at least annually,
by a qualied eld service person, to ensure
that the ow of combustion and ventilation
air is not obstructed.
During the annual service call, the burners
should be removed from the burner tray
and cleaned. Replace the embers - do not
block the pilot or burner ports.
5) Keep the area near the appliance clear and
free from combustible materials, gasoline
and other ammable
vapours and liquids.
6) Verify proper operation after servicing.
LOG REPLACEMENT
The unit should never be used with broken logs.
Turn o󰀨 the gas valve and allow the unit to cool
before opening door to carefully remove the logs.
The pilot light generates enough heat to burn
someone. If for any reason a log should need
replacement, you must use the proper replace-
ment log. The position of these logs must be as
shown in the diagram under Log Installation.
Note: Improper positioning of logs may
create carbon build-up and will alter
the unit’s performance which is not
covered under warranty.
DOOR AND GLASS
GASKET
If the door gasket requires replacement use 7/8"
diameter oval door gasket (Part # 650-920). The
glass requires 5/8" at glass gasket. See your
Regency dealer.
GOLD-PLATED DOORS
The 24 carat gold plated nish on the door
requires little maintenance, and need only be
cleaned with a damp cloth. DO NOT use abrasive
materials or chemical cleaners, as they may
harm the nish and will void the warranty. Clean
any ngerprints o󰀨 before turning the unit on.
GLASS
REPLACEMENT
Your Regency stove is supplied with high tem-
perature, 5 mm Neoceram ceramic glass that
will withstand the highest heat that your unit will
produce. In the event that you break your glass,
purchase your replacement from an authorized
Regency dealer only, and follow the step-by-step
instructions for replacement. Never operate
your unit with broken glass.
WARNING: Do not operate appliance with
the glass front removed, cracked or broken.
Replacement of the glass should be done
by a licensed or qualied service person.
