INTRODUCTION
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 Z21.88-2002-
CSA 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 out-
side.
Installation and repair of the Clarity Direct Vent Gas
Heater should be done by a qualied service person. The ap-
pliance should be inspected before use and at least annually
by a qualied 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 insur-
ance 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 efciency provided by
direct venting.
The Clarity is shipped from the factory with the log set
packed inside the rebox. To prepare the stove for instal-
lation; The log set must be unpacked. The appropriate fuel
conversion for natural gas, if desired, installed. Install the
logs as instructed.
Removing the Glass Front
NOTE: The glass front is heavy. Be prepared for its
weight when lifting it to avoid damage during removal.
The wing doors on each side are held closed by magnets.
Push on each door to open it. Loosen the wing nut on each
of the two spring-loaded levers. Grasp each lever and push
to the rear to disengage the front. To keep the levers in the
disengaged position, tighten the wing nuts. Lift the glass
front slightly and remove it from the stove. Set the glass
aside in a safe place where it will not be damaged.
WARNING: Do not abuse the Clarity's glass by
striking, slamming, or similar trauma. Do not op-
erate the Clarity Gas Heater with the glass panel
removed, cracked or broken. Use only glass supplied
by Harman and approved for use with this heater.
Do not use substitute materials. Replacement of
the panel should be done by a licensed or qualied
service person.
The use of an existing chimney as an air intake is
not covered under theANSI Z21.88b-2003. CSA2.33b-
2003 test methods and the resulting ITS/WHI product
certcation: The code Authority Having Jurisdiction
must be consulted prior to proceeding.
ASSEMBLY
Remove and Unwrap the Log Set
As shown in the photo below, the log set consists of a
back log (1), a center log that has a pilot-viewing port in
the left end (2), two ember strips (3), and a branch that rests
on top (4).
In addition, there are two side brick panels and a back
brick panel.
The log set components are shipped from the factory
individually wrapped and packed inside the stove. Take
them out of the stove, then carefully remove the wrapping.
Handle the logs gently to prevent damage.

The front is released
when spring-loaded
levers on the left and
right sides are pushed
to the rear
Install the Back Log and Back Brick Panel
These two components are installed as a single piece.
Rest the back brick panel on the shelf located on the back
side of the back log, and center it. Holding the two pieces
as a single unit, tilt the top forward slightly and manuever
it over the top of the rear burner—taking care that the top
corners clear the front opening. Place it snugly against the
back wall and center it.
Install the Side Brick Panels
These slide into place along each side and are held by
friction. The notch in each panel faces the back. Install one
side, and then the other.
Install the Ember Strips
The ember strips rest against the front of the rebox and
should t snugly. Guide them toward you and to the outside
until they t snugly. Check the air slot in the inside of the
ember strips to conrm that they do not obstruct it.
Optional Ember Screen
There is an optional ember kit available which replaces
the two-piece ember strips with a screen for over the front
burner and some rock-wool and nuggets to give a more
realistic re appearance. If choosing this option, install it
now.

16
Install the Center Log
The center log goes all the way to the back and should
be 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 Branch
Orient the branch with the forked end toward the left rear
of the stove and slip it over the two locator pins, one on top
of the back log and the other on the top of the center log.
Secure the Glass Front
NOTE: The glass front is heavy. Lift it carefully to pre-
vent damage. Center the glass on the opening and suspend
it in place by placing the the tab hooks over the top edge
of the opening. Loosen the wing nuts that hold the spring-
loaded levers in place. Press the glass slightly against the
stove to conrm that it seats properly, then press it rmly
against the front while pulling the levers forward to engage
them. Tighten the wing nuts.
The complete log set with all logs in the correct position.
ASSEMBLY
Any safety screen or guard removed for servicing an
appliance must be replaced prior to operating the ap-
pliance.

17
Burn Only the Fuel for which the Heater is Equipped
The Clarity Direct Vent is built for use with Propane
but can be converted to burn Natural Gas.The label on the
burner system module indicates the fuel for which it is
equipped, and must be marked upon installation of the stove
or conversion kit. A second label, located near the rating
plate, also indicates the fuel type.
For fuel conversion information, see APPENDIX A
(page 28)
Making The Connection
The gas inlet is located at
the bottom right rear of the
stove. The inlet tting is a 1/2"
female are exible pipe.
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 Direct Vent Gas Heater 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 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 enter-
ing into the gas train, apply compounds only to male
pipe threads and do not apply compound to the rst
two threads.
CAUTION: TEST ALL JOINTS FOR LEAKS BE-
FORE OPERATING
Gas Pressure Requirements
Correct gas pressure and the use of a properly sized
gas supply line are essential for the safe and efcient per-
formance of this appliance. Make sure that the plumber or
gas supplier checks the gas supply line and gas pressure at
installation.
NOTE: Improper gas pressure can affect heater perfor-
mance, ame color, or cause pilot outage.
WARNING: This product must be installed by a li-
censed plumber or gas tter when installed within the
Commonwealth of Massachusetts.
Natural Gas:
Maximum inlet pressure 7.0" w.c. (1.74 kPa)

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.
Be sure that all electrical connections are clean, free
from corrosion, and tight. Inspect connections periodically
to conrm that no corrosion has built up over time.
When properly installed and maintained, a millivolt
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:
RECOMMENDED WIRE GAUGES

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 Electri-
cal CodeANSI/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 three-
pronged grounding plug that should be plugged
directly into a properly grounded receptacle. Do not
cut or remove the grounding prong from the plug.

AIR SHUTTER ADJUSTMENT
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-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 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-dened 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 qualied service person
or your Harman dealer for advice.

about one (1) minute after the pilot is lit. Release the knob
and it will pop back up. Pilot should remain lit. If it goes
out, repeat steps 5 through 9.
•If the knob does not pop up when released, stop and
immediately call your service technician or gas supplier.
•If the pilot will not stay lit after several tries, turn the
gas control knob to "OFF" and call your service technician
or gas supplier.
11. Turn the gas control knob counterclockwise to
"ON."
