ASSEMBLY
The Clarity 828I Fireplace Insert comes with the
log set packed inside the rebox. The three trim
panels and two wing brackets are packed together in
a separate carton.
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.
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
replace opening should be used. The wing panels
may be trimmed to t inside the replace opening if
a ush look is desired.
Before the unit is installed, all components should
be unpacked. The cross log must be removed, the
packing material taken out, and then re-installed.
The Clarity 828I is shipped from the factory
equipped to burn propane. If Natural Gas is to be
used, conversion kit # 1-00-09009 must be installed
at this time as well. See the fuel conversion instruc-
tions in Appendix A on page 16.

Re-install the ember strips so that they rest against
the front of the rebox. Guide them toward you and
to the outside until they t snugly. Check the air slot
inside from the ember strips to conrm that they do
not obstruct it.
Install the center log so that it goes all the way to
the back and is centered. When properly positioned,
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 oriented
with the forked end toward the left rear of the stove,
and slip it over the front locator pin.
Re-install and Secure the Glass door
NOTE: The glass door is heavy. Lift it care-
fully 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 conrm
that it seats properly, then press it rmly against
the front while pushing the levers to the rear to
engage them.
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),
2-piece ember strip (3), and a cross log that rests on
top (4).
Remove the cross log, the center log, and the em-
ber strips, in that order. To remove the rear log, rst
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 rst, centered
and pushed snugly against the back wall, and slide
the fuel system module back into position.

Installation INSTALLATION
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-red
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 ue of a chimney
that serves a separate solid-fuel burning appliance.
The venting manufacturer's installation instruc-
tions must be followed exactly.
IMPORTANT: Because of the high efciency
and low ue gas temperatures of this appliance, it
is important that it be connected to a well-sealed
and efcient venting system which is capable of
registering a negative pressure while the stove is
in operation.
The most efcient venting systems are those that
have a minimum number of bends and minimal hori-
zontal runs.
The Clarity Fireplace Insert is equipped with a
thermally activated vent safety switch which will
shut down the main burner if the heater is not venting
properly. 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.
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.
DO NOT DISCONNECT OR BYPASS THE
VENT SAFETY SWITCH.
WARNING: Operation of this heater when
not connected to a properly installed and main-
tained venting system or tampering with the
vent safety shutoff system can result in carbon
monoxide (CO) poisoning and possible death.
PRELIMINARY STEPS TO PREPARE FOR
THE INSTALLATION OF THE CLARITY FIRE-
PLACE INSERT
Remove the chimney cap if one exists so that the ue
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 replace.
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
modications should be allowed under local codes.
Conrm any planned changes with local building of-
cials.

8
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 minutes
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 ue 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.

sert 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 conversion if
Natural Gas is to be burned. The label on the burner
system module indicates the fuel for which it is
equipped. The Prpoer box must be marked upon
installation or conversion.

Making The Connection
The gas inlet is located at the bottom right rear of the
Insert. The inlet tting is a 1/2" 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
connection to the appliance.
The Clarity Fireplace Insert must be disconnected 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 posi-
tion 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 not to the
rst two threads.

ASSEMBLY
Gas Pressure Requirements
Correct gas pressure and the use of a properly
sized gas supply line are essential for the safe and
efcient 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, ame color, or cause pilot outage.
DO NOT USE THIS HEATER IF ANY PART
HAS BEEN UNDER WATER OR EXPOSED TO
MOISTURE CORROSION. IMMEDIATELY
CALL A QUALlFlED SERVICE TECHNICIAN
TO INSPECT THE HEATER AND REPLACE
ANY PART OF THE CONTROL SYSTEM AND
ANY GAS CONTROL WHICH HAS BEEN UN-
DER WATER.
Connecting the Cord Set
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
remove the grounding prong from the plug.
NOTE: The convection fan requires a 120 VAC
supply for operation, but the heater can be op-
erated without the fan as in the case of a power
outage.
Plug the 3-prong grounded electrical cord plug into
the wall outlet.
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)
Minimum inlet pressure 11" w.c. (2.74 kPa)
Gas manifold pressure 10" w.c. (2.49 kPa)
Connecting the Optional Thermostat
If the optional thermostat is used, it must be
plugged into the terminal strip located behind the
right side of the air inlet grill. It can be accessed by
sliding open the control access drawer.
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 conrm that no corrosion has oc-
curred 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:

ASSEMBLY
Installing the Insert Into the replace
The Clarity Fireplace Insert has an integrated draft
hood. Therefore, a separate draft hood is not re-
quired.
Some replace openings may be large enough to
connect the draft hood to the venting after the unit
has been moved to its nal position. Some openings
will be too small and will require that the draft hood
rst be connected to the venting, and then guided
into position on the top of the insert as the unit is
pushed back into the replace.
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.
The right side trim panel installs in the same fash-
ion 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 rst.
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.
8. Install the top wing cover, which is also held in
place by the magnets.
9. Install the gold wing trim by sliding the side
pieces down from the top over each clip, one at a
time.
Install the top wing panel last using two 1/4-20 fas-
teners. 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 panels. Brass edge trim is added as the
last step of installing the wing panels.
7. Mount the side trim panel, each is held in place
by two magnets. Install the left side trim panel rst
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.
2. Line up the two draft hood guides with the
fourth heat exchanger tube from each side, as shown
above.
3. With assistance, push the insert back into the
replace, while at the same time guiding the draft
hood 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 pan-
els rst, using two 1/4-20 fasteners for each panel.
Their mounting locations are near the top and bottom
of the panel.

11
ASSEMBLY
Air Shutter Adjustment
The nal step of the installation is to check the
ame pattern, which should resemble the pattern il-
lustrated in the drawing in the next column.
The ames should be relatively well-dened 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 re according to the directions on page
12, and allow the heater to burn for approximately
15 minutes. The ames will increase in length and
become more yellow in color as the unit heats up.
Monitoring the Gas Flame
Periodically, the ames of the Clarity Fireplace
Insert should be checked while it is in operation.
The ames should be well-dened and stable. They
should be bright yellow with a blue base where at-
tached to the burner ports. The ames should not
look orange or sooty. Portions of the logs will glow
red when the ames are properly adjusted.
If you nd the ames to be other than that de-
scribed here, do not operate the heater. Consult a
qualied service person or your Harman dealer for
advice.
Three adjustment levers, one for each burner, are
used to adjust the ames for each particular instal-
lation. They are accessible when the front control
access drawer is opened. The levers may become hot
to the touch after prolonged operation. Use a glove
to avoid contact if hot. For best results, when ne-
tuning the ame picture, initially leave the middle
lever unchanged from its factory setting. Move the
other two levers as needed to increase or decrease
the brightness and length of the ame: moving left
will increase the ame; moving right will decrease
the ame.

MAINTENANCE
Maintenance
A qualied service person recommended by your
Harman dealer should conduct an annual inspection
and maintenance of your Clarity, its venting, and the
installation to keep it running safely and efciently.
These procedures should be performed only by a
qualied 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,
rst 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 rst by pulling the
top slightly away from the unit, and then litng.
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 bottom.
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 discon-
nect the wiring (Two Amp Mate-N-Lok connectors).
The trim panel will then come away from the unit.
Inspecting the Venting
An inspection of the venting system should be
made during the annual service appointment to con-
rm that there is no blockage and that the system is
in good repair. Directions for conducting a ue spill-
age test may be found on page 8. The vent manufac-
turer's instructions may provide specic 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 household
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.
Replacing the Gasket
The Clarity has 5/8" diameter berglass 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 sufcient
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 tempera-
ture silicone.
6. Close the door and apply rm pressure to seat
the gasket evenly.
CAUTION: If the door is opened or removed for

MAINTENANCE
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 rebox area. An extra-soft brush should be used
on the logs as they are extremely fragile; a vacuum
cleaner may be used on the rebox. 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 13.
2. Remove the glass door according to the direc-
tions on page 13.
3. Remove, clean, and re-install the log set, ob-
serving the directions on log handling and placement
found on page 6.
Convection Blower Service Access
The blower is located behind a panel that can be
accessed by rst removing the fuel module. See page
22. 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.

Appendix A: Fuel Conversion
Natural Gas conversion kit # 1-00-09009, available
only from the Harman Stove Company, is necessary
to complete the fuel conversion. This kit includes,
NG regulator knob assembly, Pilot orice, three
burner orices, Instructions, and a conversion label,
which must be afxed to the valve upon completion
NOTE: THE CONVERSION SHALL BE CAR-
RIED OUT IN ACCORDANCE WITH THE RE-
QUIREMENTS OF THE PROVINCIAL OR LOCAL
AUTHORITIES HAVING JURISDICTION AND IN
ACCORDANCE WITH REQUIREMENTS OF THE
CURRENT EDITION OF THE NATIONAL FUEL
GAS CODE, ANSI Z223.1 or the CAN/CGA-B149
INSTALLATION CODES.
Steps for completing the fuel conversion:
Prior to installing the fuel conversion, remove
the Glass door and the log set, to gain access to the
burner module. Remove the burner tubes by sliding
to the left while lifting upward. Remove the burner
cover plate and the tube box top as shown.
Step 1: Remove pilot hood with a 7/16" wrench.
Inside, you will nd and discard the Propane ori-
ce. Install the new Natural Gas orice from the kit.
Tighten the pilot hood and assure proper alignment
of the directional openings.
Step 2: Using a 1/2 in. deep-well socket, remove
the three main burner orices. Install the new ori-
ces accordingly; Front = #47, Middle = #56, Rear =
#44. Apply a thread sealer such as teon tape, to the
orices prior to installing. (See Appendix C)
Step 3: Using a small at-blade screwdriver, re-
move the three screw that hold the LP knob module
in place. Remove the module and replace it with the
Natural Gas module from the kit. See kit instruc-
tions.
Step 4: Afx the conversion label to the valve so
that any future service tech etc... can plainly see that
the valve was converted.
Step 5: Mark the appropriate fuel box on the unit
label, pictured at left, using a permanent marker.
THE HARMAN CLARITY GAS INSERT IS
BUILT FOR USE WITH PROPANE.
IMPORTANT: Perform a leak test upon com-
pletion of the fuel conversion.
CAUTION: LABEL ALL WIRES PRIOR
TO DISCONNECTION WHEN SERVIC-
ING CONTROLS. WIRING ERRORS CAN
CAUSE IMPROPER AND DANGEROUS
OPERATION. VERIFY PROPER OPERA-
TION AFTER SERVICING.

Appendix B: De-rating for High Altitude
For high altitude installations above 1370 meters
(4500 feet), consult the local gas distributor or the
authority having jurisdiction for proper rating meth-
ods.
NOTE: The difference in altitude derating require-
ments for the U.S. and Canada is simply a result
of differences in testing standards between the two
countries.
If the installer must convert the unit to adjust for
varying altitudes, an information sticker like the one
below must be lled out and afxed to the appliance
at the time of conversion.
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 numbers
the appropriate injectors for both LP and natural gas
at various altitudes.
For Canadian installations, the Clarity Fireplace
Insert is approved for elevations up to 1370 meters
(4500 feet).
THE CONVERSION SHALL BE CAR-
RIED OUT BY A MANUFACTURER'S
AUTHORIZED REPRESENTATIVE IN
ACCORDANCE WITH THE REQUIRE-
MENTS OF THE MANUFACTURER,
PROVINCIAL OR TERRITORIAL
AUTHORITIES HAVING JURISDIC-
TION AND IN ACCORDANCE WITH

gas line tting from the fuel module.
3. Remove the cross log, the front logs, and the
two ember strips following the directions on page 6.
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.
6. Pull the top tray forward so that it disengages;
lift the front edge up, then remove it.
8. Remove the center burner.
9. Remove the front burner.
10. Remove the 1/4-20 fasteners and retainer clip
that secure the rear burner, then remove the rear
burner.
11. Lift the rear air deector straight up, and rock it
forward.
12. Remove the orice compartment cover; (before
it can be removed, it may be necessary to use pli-
ers to straighten the tab that goes through the T-slot,
which holds the cover in place. Pull the cover to the
left and lift it out. The orices will now be visible).
13. Lift the orice compartment dividers straight
up to remove them for better access. When you re-
install the dividers, make sure they are seated all the
way in to prevent air leakage from one compartment
to another.
