Introduction
The Harman Clarity 929BV Vented Gas Heater is a
listed gas-red vented room heater tested by Intertek
Testing/Warnock Hersey to ANSI standard Z21.88-
2002, CSA 2.33-M02, and CAN/CGA-2.17-M91.
The installation of the Clarity Vented Gas Heater
must conform with local codes, or in the absence of
local codes, with the current edition of National Fuel
Gas Code, ANSI Z223.1 — latest edition and CAN
1-B1-149.1 and .2 Installation Code.
The Clarity 929BV is not for use in mobile homes.
CAUTION: This appliance must be vented to the
outside.
Installation and repair of the Clarity Vented Gas
Heater should be done by a qualied service person.
The appliance should be inspected before use and at
least annually by a qualied service person. More fre-
quent 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 instal-
lation 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. Observ-
ing required clearances to combustible materials, the
proximity to a safe chimney or venting system,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.
Adequate combustion and ventilation air must be
provided.

4
In addition to these clearances, adequate accessibil-
ity clearance for servicing and proper operation must be
maintained.
Do not in any way obstruct the combustion air inlets
that are located under the heater.
If this appliance is installed directly on carpeting, tile
or other combustible material other than wood ooring the
appliance shall be installed on a metal or wood panel ex-
tending at least the full width and depth of the appliance.
INSTALLATION
CLEARANCES
The following clearances to combustibles must be
observed:
Unit to left sidewall 9" (230 mm)
Unit to right sidewall 9" (230 mm)
Unit corner to walls 4" (100 mm)
Rear of unit to back wall 3" (75 mm)
(measured from rear of draft hood to wall)
Unit to alcove ceiling 18" (460 mm)
Maximum alcove depth 14" (355 mm)
Due to high temperatures, the Clarity Vented Gas
Heater should be located out of trafc and away
from furniture and draperies.
Children and adults should be alerted to the haz-
ards of high surface temperatures and should stay
away to avoid burns or clothing ignition.
Young children should be carefully supervised
when they are in the same room as the Clarity
Vented Gas Heater.
Clothing or other ammable materials should
not be placed on or near the Clarity Vented Gas
Heater.

VENTING
Use Only Approved Venting
The Clarity gas heater 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, an approved
Class B chimney liner 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 instructions 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 horizontal runs.
The Clarity gas heater is equipped with a thermally acti-
vated vent safety switch that 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 con-
nected to a properly installed and maintained venting
system or tampering with the vent safey shutoff system
can result in carbon monoxide (CO) poisoning and pos-
sible death.
The Clarity gas heater is equipped with its own internal
draft hood so no additional external 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.
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. If the convection air blower is installed,
it should be turned off for the test.
3. Hold a match or other source of smoke near the draft
hood outlet on the upper back of the stove.
4. If the smoke is not drawn in, turn off the heater and
determine the cause of the lack of draft. If necessary, seek
expert advice.
For sites with swirling or turbulent wind conditions, a
wind cap may solve the problem.

ASSEMBLY
The Clarity is shipped from the factory with the log set
packed inside the rebox. To prepare the stove for installa-
tion, the log set must be unpacked, the appropriate burner
system module for either natural gas or propane installed,
and the logs installed.
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 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 oper-
ate the Clarity Vented 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 substi-
tute materials. Replacement of the panel should be done
by a licensed or qualied service person.
Remove and Unwrap the Log Set
As shown in the photo above right, 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 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 as they may be damaged easily.

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.
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.

CONNECTING THE HEATER
TO A GAS SUPPLY
Burn Only the Fuel for which the Heater is Equipped
The Clarity B-Vent will burn either natural gas or pro-
pane, 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.Asecond label, located near
the rating plate, also indicates the fuel type.
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 B-Vent Gas Heater 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 position
during any pressure testing of the gas supply system at pres-
sures 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 rst two threads.
CAUTION: TESTALL JOINTS FOR LEAKS BEFORE
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.

CONNECTING THE CORDSET
The Clarity B-Vent Gas Heater must be installed in ac-
cordance 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.
CONNECTING THE
OPTIONAL THERMOSTAT
If connecting the optional thermostat, it must be plugged
into the terminal strip located on the left side near the bot-
tom of the stove.
When installing a millivolt control sys-
tem, 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:

MONITORING THE GAS FLAME
Periodically, the ames of the Clarity B-Vent Gas Heater
should be checked while it is 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.
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 on page 11 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 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 3/16" Allen wrench
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 increase the ame; turning
clockwise will decrease 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 procedure as needed until desired ame effect is
achieved.

•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."
12. Place the ON-OFF/THERMOSTAT switch in the ON
position or in the THERMOSTAT position if the optional
thermostat is used.
13. Turn on the electric power to the heater.
14. Set the optional thermostat to the desired room tem-
perature.
15. Set the High-Low Regulator to desired setting: turn
fully counterclockwise for High and fully clockwise for
Low.
NOTE: An odor resulting from the initial heating of new
materials in your heater is not unusual during the rst re,
and in most cases will disappear after an hour or two.
HOW TO TURN OFF THE FIRE
1. If using optional thermostat, set thermostat to the low-
est 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 clock-
wise to “OFF.”
NOTE: The knob cannot be turned from “PILOT” to
“OFF” unless it is pushed in slightly. Do not force it.
Operation
HOW TO LIGHT THE FIRE
1. STOP! Read the safety information on the left side
of the panel below.
2. If using the optional thermostat, set thermostat to the
lowest setting.
3. Turn off electric power to the appliance.
4. Turn the ON-OFF/THERMOSTAT switch to the OFF
position.
5. Push in the gas con-
trol knob slightly and turn
it clockwise to "OFF."
NOTE: The knob cannot be
turned from "PILOT" to "OFF"
unless it is pushed in slightly. Do
not force it.
6. Wait ve (5) minutes to clear out any gas. If you then

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 installa-
tion to keep it running safely and efciently. These pro-
cedures should be performed only by a qualied service
person. The gas supply should be turned off whenever a
maintenance procedure is performed.
If the front panel, side doors, or front access door are
removed for servicing, they must be replaced prior to
operating the Clarity.
REMOVING THE GLASS FRONT
FOR REPLACEMENT
Refer to page 6 for directions on removing the glass
front. Use only authorized Harman replacement glass
components available from your 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 proce-
dure.
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 sufcient 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 the venting system should be made
during the annual service appointment. The system must
have no blockage and must be in good repair. The vent
manufacturer's instructions may provide specic sugges-
tions 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 6.
Removal and Re-installation of the Log Set for Cleaning
CAUTION: The ceramic logs are durable when
handled and installed properly. However, they are deli-
cate 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 re-
move 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
Carefully remove rst one side panel, and then the
other. Clean and place to side.
Remove the Back Log and Back Brick Panel
Finally, carefully remove these two components as a sin-
gle piece. Brush them gently and place them to the side.
Finish the procedure by vacuuming the interior of the
rebox, then re-install the logs and secure the glass front
following the procedures on page 7.

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 NATIONALFUELGAS
CODE, ANSI Z223.1 or the CAN/CGA-B149 INSTAL-
LATION 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 lift-
ing 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 orice. Install the
new Natural Gas orice from the kit. Tighten the pilot
hood and assure proper alignment of the directional open-
ings.
Step 2: Using a 1/2 in. deep-well socket, remove the
three main burner orices. Install the new orices accord-
ingly; 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
orices prior to installing.
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: 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
using a permanent marker.
Step 6: Afx the Installer Fuel Label in place of the exist-
ing one.
Important: Perform a leak test upon completion
of the fuel conversion.

Appendix B
DE-RATING FOR HIGH ALTITUDE
For U.S. installations, the Clarity B-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 B-Vent is ap-
proved for elevations up to 610 meters (2000 feet). For
installations from 610-1370 meters (2000-4500 ft.) the
orice sizes (DMS) for natural and propane gas are as
shown in the chart below.

For high altitude installations consult the local gas dis-
tributor 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 below must be
lled out and afxed to the appliance at the time of conver-
sion.
THE CONVERSION SHALL BE CARRIED OUT
