Remove the chimney cap if one exists so that the
flue may be cleaned and the venting installed.
Remove any existing hearth accessories such as
glass doors, spark screens, andirons, and grates.
Clean the chimney thoroughly to remove ash, soot,
and any obstructions, and then clean ash, soot, dust,
and debris from the fireplace.
The damper must be locked open to allow the 4"
venting to pass through. If it is necessary to modify
the damper area to allow passage of the venting, the
modifications should be allowed under local codes.
Confirm any planned changes with local building
officials.
VENTING
Use Only Approved Venting
The Clarity 828I Vented Gas Fireplace Insert is
tested and listed for connection to a 4" (100 mm)
listed Class B venting system.
If the unit is installed to vent through an approved
masonry chimney or a factory-built chimney system,
a listed lining system approved for use with gas-fired
appliances must be used.
Observe local codes when venting the Clarity. If
no local codes exist, follow the current edition of ANSI
Z223.1 and CAN1- B149 installation codes.
Do not connect the venting to the flue of a chim-
ney that serves a separate solid-fuel burning appli-
ance.
The venting manufacturer's installation instructions
must be followed exactly.
IMPORTANT: Because of the high efficiency and
low flue gas temperatures of this appliance, it is
important that it be connected to a well-sealed and
efficient venting system which is capable of regis-
tering a negative pressure while the stove is in op-
eration.
The most efficient venting systems are those that
have a minimum number of bends and minimal hori-
zontal runs.
The Clarity Fireplace Insert is equipped witha ther-
mally activated vent safety switch which will shut
down the main burner if the heater is not properly
venting. The safety switch will automatically reset
after the heater has cooled down.
The switch will continue to cycle off and on until
the venting problem is corrected. If you are unable
to correct the venting problem, seek expert advice
from your Harman dealer or installer.
DO NOT DISCONNECT OR BYPASS THE
VENT SAFETY SWITCH.
WARNING: Operation of this heater when not
connected to a properly installed and maintained
venting system or tampering with the vent safety
shutoff system can result in carbon monoxide (CO)
poisoning and possible death.
The Clarity Fireplace Insert is equipped with its own
integral draft hood so no additional draft hood is
required. The heater should be installed so that the
draft hood is in the same atmospheric pressure zone
as the air inlets to the heater.
TEST FOR FLUE SPILLAGE
A spillage test should always be made at the
completion of the installation, and at least annually
thereafter.
1. Start all exhaust fans in the home and then close
all doors and windows in the room containing the
heater.
2. Light the heater and allow it to run for 5 min-
utes on the high output setting. The convection air
blower should be turned off for the test.
3. Remove the left trim panel, which is held in place
by a clip at the bottom and a magnet at the top, and
place a source of smoke (such as a match, lighter, or
a cigarette) in front of the flue spillage test tube.
The smoke should be drawn into the tube. If it is
not, let the heater run for 5 more minutes and repeat
the test.
4. If the smoke is not drawn into the tube, turn off
the heater and determine why there is no draft. If
necessary, seek expert advice.
For sites with swirling or turbulent wind condi-
tions, a wind cap may solve the problem.

Assembly
The Clarity 828I Fireplace Insert comes with the
log set packed inside the firebox. The three trim
panels and two wing brackets are packed together
in a separate carton. NOTE: The wing brackets
must go on before the door.
A second shipping carton contains the wing
panels. Two different size wing panel sets are
available for the Clarity Insert: large (32-1/2" X
44"), and small (30" X 40"). The set that will work
best with the fireplace opening should be used.
The wing panels may be trimmed to fit inside the
fireplace opening if a flush look is desired.
Before the unit is installed, all components
should be unpacked. The cross log must be re-
moved, the packing material taken out, and then
re-installed.
The Clarity 828I is shipped from the factory
equipped to burn either natural gas or propane. If
the alternate fuel is to be used, the appropriate
burner system module must be installed at this
time as well. See the fuel conversion instructions in
Appendix A on page 15.
Removing the Glass door
NOTE: The glass door is heavy. Be prepared for
its weight when lifting it to avoid damage during
removal.
Locate latches on each side of the glass door.
Then, grasp each latch handle and pull forward
until the front is disengaged. Lift the glass door
slightly and remove it
from the stove. Set the
glass door aside in a
safe place where it
will not be damaged.
WARNING: Do not
abuse the glass on the
Clarity Fireplace
Insert front by strik-
ing, slamming, or
similar trauma. Do
not operate this
Fireplace Insert with
the glass panel re-
moved, cracked or
broken. Use only glass
supplied by Harman and approved for use with
this heater. Do not use substitute materials. Re-
placement of the panel should be done by a li-
censed or qualified service person.
Removing and Replacing logs
The log set consists of a back log (1), a center log
that has a pilot-viewing port in the left end (2),
ember strip (3), and a cross log that rests on top
(4).
Remove the cross log, the center log, and the
ember strips, in that order. To remove the rear log,
first pull the fuel system module forward about an
inch to create clearance, then lift the log out.
Re-install the logs in the same order that they
were removed. Place the rear log in position first,
centered and pushed snugly against the back wall,
and slide the fuel system module back into posi-
tion.
Re-install the ember strips so that they rest
against the front of the firebox. Guide them to-
ward you and to the outside until they fit snugly.
Check the air slot in the inside of the ember strips
to confirm that they do not obstruct it.

INSERT TO A GAS SUPPLY
Burn Only the Fuel for Which the Heater is Equipped
The Clarity Fireplace Insert will burn either
natural gas or propane, but requires a dedicated
burner system module for either fuel. The label on
the burner system module indicates the fuel for
which it is equipped.
Making The Connection
The gas inlet is located at the bottom right rear of
the Insert. The inlet fitting
is a 1/4" male pipe
thread.
A separate gas shut-off
valve and a 1/8" N.P.T.
plugged tapping should
be installed immediately
upstream of the connec-
tion to the appliance.
The ClarityFireplace
Insert must be discon-
nected from the gas supply piping during any
pressure testing of that system at pressures in
excess of 1/2 psig (3.5 kPa).
The Clarity gas control valve must be in the OFF
position during any pressure testing of the gas
supply system at pressures equal to or less than
1/2 psig (3.5 kPa).
WARNING: To avoid pipe compounds from
entering into the gas train, apply compounds
only to the male pipe threads and only to the first
two threads.
CAUTION: TEST ALL JOINTS FOR LEAKS
PROPANE
NATURAL
Inlet
Log Positions When Assembled
Install the center log so that it goes all the way to
the back and is centered. When properly posi-
tioned, there should be an even gap along the front
of the center burner in the cavity in the log. A
small portion of the log support frame will be
revealed. The center log has a round viewing port
in the left end through which the pilot can be
observed.
Install the cross log, making sure that it is ori-
ented with the forked end toward the left rear of
the stove, and slip it over the front locator pin and
position as shown below.
Re-install and Secure the Glass door
NOTE: The glass door is heavy. Lift it carefully to
prevent damage. Center the glass on the opening
and suspend it in place by placing the tab hooks
over the top edge of the opening. Press the glass
slightly against the stove to confirm that it seats
properly, then press it firmly against the front
while pushing the levers to the rear to engage
them.

The Clarity Fireplace Insert, when installed, must
be electrically grounded in accordance with local
codes or, in the absence of local codes, with the the
current edition of the National Electrical Code,
ANSI/NFPA 70 in the United States or the current
Canadian Electrical Code CSA 22.1 in Canada.
This appliance is equipped with a three-prong
(grounding) plug for protection against shock haz-
ard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or re-
move the grounding prong from the plug.
NOTE: The convection fan requires a 120 VAC
supply for operation, but the heater can be operated
without the fan as in the case of a power outage.
Plug the 3-prong grounded electrical cord plug
into the wall outlet.
CONNECTING THE
OPTIONAL THERMOSTAT
If the optional thermostat is used, it must be
plugged into the terminal strip located behind the
right side air inlet grill. It can be accessed by first
opening the control access door and then pulling up
and forward on the air grill. The terminal block will
then be visible.
When installing a millivolt control system, use
only a special low resistance thermostat. Do not use
a regular heating thermostat.
Be sure that all electrical connections are clean,
free from corrosion, and tight. Inspect connections
periodically to confirm that no corrosion has built
up over time.
When properly installed and maintained, a mil-
livolt control system should give many years of
trouble-free service.
It is important to use wire of a gauge proper for
the length of the wire:

INSTALLING THE INSERT
BEFORE OPERATING
Gas Pressure Requirements
Correct gas pressure and the use of a properly
sized gas supply line are essential for the safe and
efficient performance of this appliance. Make sure
that the plumber or gas supplier checks the gas sup-
ply line and gas pressure at installation.
NOTE: Improper gas pressure can affect heater
performance, flame color, or cause pilot outage.
Natural Gas:
Maximum inlet pressure 7.0" w.c. (1.74 kPa)
Minimum inlet pressure 5.0" w.c. (1.25 kPa)
Gas manifold pressure 3.5" w.c. (0.87 kPa)
LPG Gas:
Maximum inlet pressure 13" w.c. (3.24 kPa)

panels first, using two 1/4-20 fasteners for each
panel. Their mounting locations are near the top
and bottom of the panel.
Install the top wing panel last using two 1/4-20
fasteners. The mounting holes are near the inside
edge of the side wing panels.
Before tightening, make sure the outer edges of
the top panel align with the edge of the side pan-
els.
Brass edge trim is added as the last step of install-
ing the wing panels.
7. Mount the side trim panel—each is held in
place by two magnets.
Install the left side trim panel first by placing the
bottom close to where it goes, then align the top
and move it close to the insert body until it is held
snugly by the two magnets.
The right side trim panel installs in the same
fashion as the left, but the wiring (Two Amp Mate-
N-Lok connectors) that serves the On-Off switch at
the top of the panel and the blower speed control
switch on the bottom must be connected first.
Move the right panel close enough to make the
connection. Align the three wire male connector
with the latch to the bottom. Push into the three
wire female connector on the stove until it clicks.
Do the same with the two wire connector with the
latch turned to the top. move panel into place
while routing the switch wires into the opening of
the wing bracket. Secure the panel.
AIR SHUTTER ADJUSTMENT
The final step of the installation is to check the
flame pattern, which should resemble the pattern
illustrated in the right column.
The flames should be relatively well-defined and
stable. They should be bright yellow with a blue
base where attached to the burner ports, and
should not look orange or sooty.
Start the fire according to the directions on page
11 and allow the heater to burn for approximately
15 minutes. The flames will increase in length and
become more yellow in color as the unit heats up.
Three adjustment levers—one for each burner—
are used to adjust the flames for a particular
installation. They are accessible when the front
control access door is opened. The levers may
become hot to the touch after prolonged operation.
INTO THE FIREPLACE
The Clarity Fireplace Insert has an integrated
draft hood, so a separate draft hood is not re-
quired.
Some fireplace openings may be large enough to
connect the draft hood to the venting after the unit
has been moved to its final position. Some openings
will be too small and will require that the draft
hood first be connected to the venting, and then
guided into position on the top of the insert as the
unit is pushed back into the fireplace.
Particularly in installations with tight clearances,
the procedure will be most easily accomplished if
the trim and wing panels are installed as the last
step.
Follow these steps:
1. Connect the Clarity Insert's detachable draft
hood to the end of the venting by sliding it inside
the venting, then secure it with three sheet metal
screws.
2. Line up the two draft hood guides with the
fourth heat exchanger tube in on each side on the
back of the stove as shown above.
3. With assistance, push the insert back into the
fireplace, while at the same time pulling on the
draft hood to coax it into position. Continue until
both guides are far enough forward that the
retainer clamps and nuts can be installed on the
threaded guide bolts.
4. Tighten the nuts to secure the draft hood.
5. Adjust the rear levelling bolts until the unit is
level.
6. Install the wing panels; they attach to brackets
on each side of the Clarity. Install the side wing

Use a glove to avoid contact if hot. For best results
when fine-tuning the flame picture, initially leave
the middle lever unchanged from its factory set-
ting. Move the other two levers as needed to
increase or decrease the brightness and length of
the flame: moving left will increase the flame;
moving right will decrease the flame.
MONITORING THE GAS FLAME
Periodically, the flames of the Clarity Fireplace
Insert should be checked while it is in operation.
The flames should be well-defined and stable. They
should be bright yellow with a blue base where
attached to the burner ports. The flames should not
look orange or sooty. Portions of the logs will glow
red when the flames are properly adjusted.
If you find the flames to be other than that
described here, do not operate the heater. Consult
a qualified service person or your Harman dealer
for advice.
Operation
HOW TO LIGHT THE FIRE
1. STOP! Read the safety information on the
lighting instructions label on the stove.

during the first fire, and in most cases will disap-
pear after an hour
or two.
HOW TO TURN
OFF THE FIRE
1. If using an
optional thermostat,
set thermostat to the lowest
position.
2. Turn off the electric power to the appliance.
3. Turn the ON-OFF/THERMOSTAT switch to
the OFF position.
4. Push in the gas control knob slightly and turn
it clockwise to “OFF.”
NOTE: The knob cannot be turned from “PI-
LOT” to “OFF” unless it is pushed in slightly.
Do not force it.
Maintenance
A qualified service person recommended by your
Harman dealer should conduct an annual inspec-
tion and maintenance of your Clarity, its venting,
and the installation to keep it running safely and
efficiently. These procedures should be performed
only by a qualified service person. The gas supply
should be turned off whenever a maintenance
procedure is performed.
Any access panels that are removed for servicing
must be replaced prior to operating the Clarity
828I Vented Gas Fireplace Insert.
REMOVING THE GLASS DOOR
AND TRIM PANELS
To gain access to the latches that secure the door,
frist remove the two side trim panels. Each is held
in place by a magnet at the bottom and a magnet
at the top.
Remove the left side trim panel first by pulling
the top slightly away from the unit, and then
lifitng.
The right side trim panel is removed in the same
fashion as the left, but is tethered to the Insert by
the wiring that serves the On-Off switch at the top
and the blower speed control switch on the bot-
tom.
Disengage the right side panel, then pull gently
on it to create enough space so that you can reach
the latch that holds the door. If more space is
needed to gain access to the latches, reach inside
and disconnect the wiring (Two Amp Mate-N-Lok
connectors). The trim panel will then come away
from the unit.
REPLACING THE GASKET
The Clarity has 5/8" diameter fiberglass gasket
around the glass door. Should it ever need replace-
ment, use only the proper replacement gasket that
is available from your Harman dealer. To replace
the gasket, follow this procedure.
1. Remove the front according to directions
above.
2. Remove the existing gasket and clean its
channel with a scraper or wire brush.
3. Lay a thin bead of high temperature silicone
the entire length of the channel.
4. Place the gasket in the channel with sufficient
pressure that it stays in place.
5. Trim the excess from the end of the gasket so
that it butts snugly against the other end without
leaving a gap. Seal the end joint with high tem-
perature silicone.
6. Close the door and apply firm pressure to seat

confirm that there is no blockage and that the
system is in good repair. Directions for conducting
a flue spillage test may be found on page 6. The
vent manufacturer's instructions may provide
specific suggestions or details on vent inspection.
Any sections that are taken apart for the inspection
must be reassembled and sealed as required.
CLEANING THE GLASS
The glass may be cleaned with ordinary house-
hold glass cleaner and a soft cloth or paper towel.
WARNING: Never clean the glass when it is
hot. Do not use abrasive cleaners on the glass.
CLEANING THE LOG SET AND FIREBOX
During the annual inspection and maintenance
appointment, the service person should clean dust,
lint, and any light accumulation from the logs and
the firebox area. An extra-soft brush should be
used on the logs as they are extremely fragile; a
vacuum cleaner may be used on the firebox. If at
any time the logs cannot be removed or installed
without forcing, the cause must be found. The logs
must never be forced. Follow this sequence:
1. Remove the side trim panels according to the
directions on page 12.
2. Remove the glass door according to the direc-
tions on page 12.
3. Remove, clean, and re-install the log set, observ-
ing the directions on log handling and placement
found on pages 7 and 8.
CONVECTION BLOWER SERVICE ACCESS
The blower is located behind a panel that can be
accessed by first removing the fuel module. See
page 15 for instructions. Remove the two fasteners
securing the panel and pull the panel forward. The
blower will come out with the panel. Disconnect
the blower electrical connector to completely
remove the blower from the unit.
CAUTION: If the door is opened or re-
moved for servicing, it must be replaced and
securely closed before operating the appli-
ance. The glass must be securely fixed in the
door when operating the appliance.

Appendix A: Fuel Conversion
CONVERTING THE CLARITY FIREPLACE
INSERT FROM ONE GAS TO ANOTHER IN
THE FIELD
NOTE: THE CONVERSION SHALL BE CAR-
RIED OUT IN ACCORDANCE WITH THE RE-
QUIREMENTS OF THE PROVINCIAL OR LO-
CAL AUTHORITIES HAVING JURISDICTION
AND IN ACCORDANCE WITH REQUIRE-
MENTS OF THE CURRENT EDITION OF THE
NATIONAL FUEL GAS CODE, ANSI Z223.1 or
the CAN/CGA-B149 INSTALLATION CODES.
CONVERSION KIT COMPONENTS
• Burner system module
• Conversion label
The Clarity Fireplace Insert is designed to burn
either natural gas or propane, but requires a dedi-
cated burner system module for either fuel. Conver-
sion to the alternate fuel is a simple matter of replac-
ing one burner system module with another. A label
on the burner system module will specify for which
fuel it is intended.
To accomplish the conversion procedure, follow
these steps.
1. Remove the trim panels and the glass door ac-
cording to the directions on page 12.
2. Disconnect the electrical connections and the gas
line fitting from the module.
3. Remove the cross log, the front logs, and the two
ember strips following the directions on page 7.
4. Pull the module out an inch or so so that there is
enough room to remove the rear log.
5. Remove the Burner System Module
The module can be removed as an integrated unit
by simply pulling the module forward.
6. Install the replacement module, re-install the logs,
re-connect the wiring connections and gas line fit-
ting, secure the glass door, and replace the trim pan-
els.
After completing the fuel conversion, an installer
fuel label—supplied with the burner system mod-
ule—must be filled out by the installer and attached
to the stove.
SEE WIRING DIAGRAM ON PAGE 18
The above label on the Clarity's burnersystem module indicates
that the unit is equipped to burn natural gas. Asimilar label is
used for Propane.
CAUTION: LABEL ALL WIRES PRIOR TO DISCONNEC-
TION WHEN SERVICING CONTROLS. WIRING ER-
RORS CAN CAUSE IMPROPER AND DANGEROUS
OPERATION. VERIFY PROPER OPERATION AFTER
SERVICING.

Appendix B: De-rating for High Altitude
For U.S. installations, the Clarity Fireplace Insert
is approved for elevations up to 2000 feet using the
factory-installed burner injectors. At elevations
above 2000 feet, U.S. codes require a decrease in
the input rating by changing the burner injectors to
a smaller size. The chart below lists by part num-
bers the appropriate injectors for both LP and natu-
ral gas at various altitudes.
For Canadian installations, the Clarity Fireplace
Insert is approved for elevations up to 1370 meters
(4500 feet).
For highaltitude installations above 1370 meters (4500
feet), consult the local gas distributor or the authority
having jurisdiction for proper rating methods.
NOTE: The difference in altitude derating require-
ments for the U.S. and Canada is simply a result of dif-
ferences in testing standards between the two coun-
tries.
If the installer must convert the unit to adjust for vary-
ing altitudes, an information sticker like the one below
must be filled out and affixed to the appliance at the
time of conversion.
THE CONVERSION SHALL BE CARRIED OUT
BY A MANUFACTURER'S AUTHORIZED REP-
RESENTATIVE IN ACCORDANCE WITH THE
REQUIREMENTS OF THE MANUFACTURER,
PROVINCIAL OR TERRITORIAL AUTHORI-
TIES HAVING JURISDICTION AND IN AC-
CORDANCE WITH THE CURRENT EDITION
OF THE REQUIREMENTS OF THE CAN/CGA-
