The Harman Clarity Direct Vent 929DV Gas Heater is a
listed gas-red direct vent room heater tested by Inchcape
Testing/Warnock Hersey to standard ANSI Z21.88-2002CSA 2.33-2002, and CAN/CGA-2.17-M91.
The installation of the Clarity Direct Vent Gas Heater must
conform with local codes, or in the absence of local codes,
with National Fuel Gas Code, ANSI Z223.1 — latest edition
and CAN 1 B1-149.1 and .2 Installation Code.
Also for use in mobile (manufactured) homes after home
is sited.
Mobile (manufactured) home installations must adhere
to the current edition of Title 24 CFR, part 3280, or CSA
Z240.4.
CAUTION: This appliance must be vented to the outside.
Installation and repair of the Clarity Direct Vent Gas
Heater should be done by a qualied service person. The appliance should be inspected before use and at least annually
by a qualied service person. More frequent cleaning may
be required due to excessive lint from carpeting, bedding
material, etc. It is imperative that control compartments,
burners, and circulating air passageways of the Clarity be
kept clean.
When operating your Harman Clarity Gas Heater, respect
basic safety standards. Read these instructions carefully
before you attempt to operate the heater. Failure to do so
may result in damage to property or personal injury and may
void the product warranty.
Consult with your local building code agency and insurance representative before you begin your installation to
ensure compliance with local codes, including the need for
permits and follow-up inspections.
Several issues must be addressed when selecting a suitable
location for your Clarity Gas Heater. Observing required
clearances to combustible materials, the proximity to a safe
chimney or venting system location, and the accessibility
of the gas and electrical supply must all be considered. In
addition, selecting a location that takes advantage of the
building's natural air ow is also desirable to maximize the
heating effectiveness of the heater. In many cases, this is a
central location within the building.

Connecting To An Existing Chimney
The Clarity may be connected to an existing masonry
chimney by using a Simpson Dura-Vent conversion kit
#934.
With this kit and a 4" ex liner in the chimney, the ue
gases exit through the 4" liner, and the outside air comes
down the chimney, in the space between the chimney and
the liner. This method allows you to install the Clarity using
your chimney and still get the added efciency provided by
direct venting.
The use of an existing chimney as an air intake is
not covered under the ANSI Z21.88b-2003. CSA 2.33b2003 test methods and the resulting ITS/WHI product
certcation: The code Authority Having Jurisdiction
must be consulted prior to proceeding.
The Clarity is shipped from the factory with the log set
packed inside the rebox. To prepare the stove for installation; The log set must be unpacked. The appropriate fuel
conversion for natural gas, if desired, installed. Install the
logs as instructed.

CONNECTING THE HEATER TO CORDSET
Connecting the Cordset
The Clarity Direct Vent Gas Heater must be installed
in accordance with local codes or, in the absence of local
codes, with the most recent edition of the National Electrical Code ANSI/NFPA 70, or the current Canadian Electrical
Code C22.1.
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.
WARNING: This heater is equipped with a threepronged grounding plug that should be plugged
directly into a properly grounded receptacle. Do not
cut or remove the grounding prong from the plug.
Connecting the Optional Thermostat
If the optional thermostat is used, it must be plugged
into the terminal strip located in the left rear corner of the
heater.
When installing a millivolt control system, use only
a special low resistance thermostat. Do not use a regular
heating thermostat.

The nal step of the installation is to check the ame
pattern, which should resemble the pattern illustrated in the
right column: The ames should be relatively well-dened
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 heater according to the directions, and allow the
heater to burn for approximately 15 minutes. The ames
will increase in length and become more yellow in color as
the Clarity heats up.
If the ames do not resemble the description above and
the illustration in the right column, the air shutters may
need to be adjusted.
Three separate screws—one for each burner—are used to
adjust the ames for a particular installation. Two of them
are accessible through the side access port on the right side
of the stove. The third is accessible from the front when
the control door is open. The screws 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 screw unchanged from
its factory setting. Turn the other two screws as needed to
increase or decrease the brightness and length of the ame:
turning counterclockwise will decrease the ame; turning
clockwise will increase the ame.
1. To adjust the rear burner, open the right wing door,
reach through the side access port, and turn the rear screw
to adjust ame (see directions above).
2. To adjust the front burner, rst open the control door,
then turn the front screw to adjust ame (see directions
above).
Repeat the procedure as needed until the desired ame
effect is achieved.
Monitoring the Gas Flame
Periodically, the ames of the Clarity Direct Vent Gas
Heater should be checked while it is in operation. The
ames should be relatively well-dened and stable. They
should be bright yellow with a blue base where attached
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 described here,
do not operate the heater. Consult a qualied service person
or your Harman dealer for advice.
The Clarity ame pattern will resemble this when the unit is
burning properly.
The properly-burning pilot will
resemble the illustration to the
right.

MAINTENANCE
A qualied 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 efciently. The following procedures
should be performed only by a qualied service person. The
gas supply should be turned off whenever a maintenance
procedure is performed.
If the glass front, side doors, or front access door are
removed for servicing, they must be replaced prior to operating the Clarity.
Removing the Glass for Replacement
To remove the glass panel in the door, remove upper and
lower glass clips and lift the glass out. Use only authorized
Harman replacement glass components available from your
Harman dealer.
Replacing the Gasket
The Clarity has 5/8" diameter berglass gasket in the front
door. Should it ever need replacement, use only the proper
replacement gasket that is available from your Harman
dealer. To replace the gasket, follow this procedure.
1. Open the door
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. Lay the gasket in the channel with sufcient pressure
that is 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 temperature silicone.
6. Close the door and apply rm pressure to seat the gasket
evenly throughout.
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.
Inspecting the Venting
An inspection of both the inner and outer pipes of the
venting system should be made during the annual service
appointment. They must have no blockage and be in good
repair. The vent manufacturer's instructions may provide
specic suggestions or details on vent inspection. Any sections that are taken apart for the inspection must be reassembled and sealed as required.
Cleaning the Log Set and Firebox
During the annual inspection and maintenance appoint-
ment, 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.
Removing the Front
See directions on page 15.
Removal & Re-installation of the Log Set for Cleaning
CAUTION: The ceramic logs are durable when handled
and installed properly. However, they are delicate and may
be damaged easily if not handled with care. Handling damage to the ceramic logs is not covered by warranty.
DO NOT HANDLE LOGS WHILE THEY ARE HOT.
ALLOW PLENTY OF TIME FOR THE STOVE TO COOL
COMPLETELY BEFORE HANLDING.
Remove the Branch
Detach the branch from the two locator pins and remove
it. Brush it gently and carefully place it to one side.
Remove the Center Log
Lift the center log and remove it. Brush it gently and
carefully place it to one side with the branch.
Remove the Ember Strips
Carefully remove the ember strips, clean them, and place
them with the other logs.
Remove the Side Brick Panels

Step 3: Using a small at-blade screwdriver, remove
the three screws that hold the LP knob module in place.
Remove the module and replace it with the Natural Gas
module from the kit. See kit instructions.
Step 4: Afx 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
using a permanent marker.
Step 6: Afx the Installer Fuel Label in place of the exist-
ing one.
Important: Perform a leak test upon completion
of the fuel conversion.

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.
Step 1: Remove pilot hood with a 7/16” wrench. Inside,
you will nd and discard the Propane orice. Install the
new Natural Gas orice 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 orices. Install the new orices accordingly; Front = #47, Middle = #56, Rear = #39. Notice
the #56 that you removed from the front will be used in
the middle for Natural Gas. Apply a thread sealer to the
orices prior to installing.
The above label on the Clarity's
burner system module indicates
that the unit is equipped to
burn natural gas.
CAUTION: LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS
CAN CAUSE IMPROPER AND DANGEROUS OPERATION.
VERIFY PROPER OPERATION AFTER SERVICING.
The above label on the Clarity's
burner system module indicates
that the unit is equipped to burn
propane.

De-rating for High Altitude
For U.S. installations, the Clarity Direct Vent 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 Direct Vent is approved for elevations up to 1375 meters (4500 feet). When installing
the Clarity Direct Vent at altitudes above 1375 meters (4500 feet), consult the local gas distributor or the authority having
jurisdiction for proper rating methods.
NOTE: The difference in altitude derating requirements 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 to the right must be
lled out and afxed to the appliance at the time of conversion.
