DAILY OPERATION
The Luno is easily operated by the homeowner once it
is installed and adjusted by qualified service personnel.
The unit can be controlled automatically via the
programmable remote control, or manually by placing
the Remote Control Receiver switch in the ‘ON’ position
during the heating season. When using the remote T-
stat transmitter (switch in the ‘REMOTE’ position), set
it to the desired room temperature and the unit will
cycle on and off as required. If you select the ‘ON’
position the unit will run (burn) regardless of room
temperature. You can vary the rate of heat output by
adjusting the variable output control located on the
gas control valve to meet the heating requirements of
the season. Choosing a low flame setting will result in
longer burn cycles at a reduced output, while choosing
a high flame setting will result in a shorter, hotter burn
cycle. Through trial and error, the homeowner can
select the optimum flame size for their setting and
application.
During the summer non-heating season, switch the
remote receiver to “OFF”, and turn off the pilot. This
will improve the overall efficiency of the unit as the
fuel used by the pilot is wasted. When putting the unit
back into service, follow the lighting instructions
described on page 17.
When the unit is first lit, especially when cool, it is
normal to experience some condensation on the inside
of the window glass. This condensation will evaporate
within the first few minutes of operation. If you note
continuous condensation on the window glass or
dripping water from any part of the unit or venting
system (chimney), immediately discontinue operation
of the unit and contact qualified service personnel.
Clean the area around, under, and behind the unit on
a regular basis to prevent the accumulation of dust
and lint.
The Luno requires minimal routine maintenance and
care. Ensure the Luno is cool and off while cleaning,
or servicing. Have qualified service personnel inspect
the unit, and venting system once a year to insure that
they are clean, free of obstructions, safe, and in good
working order. If service or maintenance is required,
ensure qualified service personnel perform it.
SERVICE CAUTION
If you believe your Luno is in any way, not performing
properly, immediately discontinue operation until the
unit is inspected and approved by qualified service
personnel. Prior to servicing the unit, turn the valve
control knob clockwise to “OFF”. The unit should be
cool prior to servicing and cleaning. Use of any
components not supplied by Hearthstone on the stove
voids all warranties. Do not substitute
components.
CAUTION: REPLACE ANY SHIELD, DOOR, OR
SAFETY SCREEN COMPONENT REMOVED FOR
SERVICING, PRIOR TO OPERATING THE UNIT.
WARNING: Failure to position the parts
in accordance with these diagrams or failure
to use only the parts specifically approved
with this appliance may result in property
damage or personal injury.
Conditionally approved for purchased mobile home
installation. This appliance may be installed in an aftermarket
permanently located, manufactured (mobile) home, where
permitted by local codes.
This appliance is only for use with the types of gas indicated
on the rating plate (NG and LP). This appliance is factory set
to burn Natural Gas (NG), but is easily converted for use with

UNPACKING AND INSPECTION
Unpack and Inspect for Damage -
The Luno is packaged to withstand shipment without
damage. However, damage can still occur during
transit; so take care to inspect for damage when
unpacking and installing the unit. If any damage or
missing parts are detected, immediately contact your
dealer.
Do not install, or put into service, a
damaged or incomplete heater.
The Luno requires a pilot shield. This shield is
shipped with the unit. Ensure the shield is
installed over the pilot with the open end to the
left (when you are facing the front of the unit).
Inspect the Luno for visible or concealed damage. The
unit should appear to be square and true. The metal
parts should be smooth and free of bends and dents.
The painted surfaces should be free of scratches
flaking, or blemishes. If visible or concealed damage is
found or suspected, contact your dealer for
instructions.
Always use great care when handling the decorative
fire logs, as they are fragile and will break if handled
roughly. If a broken log is encountered, contact your
dealer for replacement logs. Otherwise, set the logs
aside until called for during the installation.

HearthStone Quality Home Heating Products, Inc. Luno Model #8160
INSTALLING THE LUNO
HEARTH REQUIREMENT/FLOOR PROTECTION
The Luno may be placed directly on a non-combustible
surface or wood floor. When installing the Luno on
carpet, vinyl, or any other combustible floor other than
wood flooring, it must be installed on any non-
combustible or wood panel extending the full width
and depth of the stove.
CLEARANCE TO COMBUSTIBLES
Due to high surface temperatures, install the unit out
of traffic and away from furniture and draperies. Do
not place clothing and other flammable material on or
near the heater. When positioning the unit always
maintain adequate clearances around air openings into
the combustion chamber and allow for adequate
ventilation. You must maintain minimum clearances to
combustibles as shown in the illustrations of this
section.
Ensure you consider the need for access to the gas
control valve access door on the front of the unit as
well as full access for periodic cleaning and servicing.
Caution: These clearances represent
minimum distances in all cases, which, through
testing in an independent laboratory to ANSI and
CSA standards, will prevent fire or spontaneous
combustion. We do not control the combustible
materials exposed to heat by this product;
therefore, an assessment must be made by the
installer to prevent consequential damage of
walls and flooring.
OPENING THE FRONT DOOR
In order to gain access to the firebox you must open
the front door. The door is held closed with two
machine screws, one on the top above the door, and
one below the lower right corner of the door. To
access these screws you must remove both the top
stone and open the lower control access door located
just below the front door. Do not remove the stone
leveling screw containing the brass lock nut. Use the
provided tool to release the pressure on the screws
before removal. Remove the mounting screw using a
4mm or 5/32” Allen wrench. Replace these screws
when the door is closed for operation; the door
will not seal without them. Use the provided tool to
apply pressure on the door seal before installing the
screws (see Figure 2).
Figure 2 – Door Assist Tool
INSTALLING THE DECORATIVE TOP STONE
Remove the top stone from the packaging carefully.
Despite the mass of the piece of soapstone, it will
break if dropped. Locate the hole drilled in the bottom
of the stone. This hole will determine the bottom and
front of the stone. Place the stone on the platform
above the door accordingly. Adjust the stone so it has
an even gap all around the back against the stove wall.

VENTING INFORMATION
VENT CONNECTION
1. The Luno Direct Vent is approved for
installation only with the vent connecting
components listed; Simpson Dura-Vent Direct
Vent GS, AmeriVent Direct, Selkirk Direct
Temp™ or Secure Vent systems. Use the
following instructions along with the pipe
manufacturer’s instructions to complete the
installation.
2. Install the vent system according to the
manufacturer’s instructions.
RESTRICTION PLATE
There is a vent restriction plate that adjusts the
flow rate of exhaust gases. This ensures proper
flame characteristics and efficiency for the wide
variety of vent configurations. Controlling the draft
also changes the aesthetics of the flame. The
restriction plate consists of a rotating shutter in the
flue connector. This shutter is attached to a rod
that protrudes through the back of the pipe. This
rod has a lock nut attached. On the very end of the
rod is an indicator slot. This slot shows the relative
position of the restrictor shutter. If the slot is
pointing up and down (12+ 6 o’clock position) the
restrictor is open. If it is pointing left and right (9+3
o’clock, the restrictor is in the closed position.
The restriction plate has unlimited settings.
Depending on the vent configuration, you may be
required to adjust the restriction plate position.
Once the desired position is reached, use a 7/16”
wrench to lock down the hex nut.

INSTALLATION INSTRUCTIONS FOR THE
STANDARD HORIZONTAL TERMINATION
MINIMUM VENTING KIT
1. Install the 24” straight section on top of the vent
connector.
2. Place the 90-degree elbow on the 24” section. Facing
the direction expected to penetrate the wall.
3. Attach the 12” straight section to the 90-degree elbow.
Move the stove and pipe assembly backwards until the
12” straight is flush against the wall. Pull up on the pipe
to ensure that there is a ¼” per foot rise coming out of
the stove to the wall.
4. Draw a circle around the pipe. Use the center of this
circle as the center point of the 10” x 10” square wall
pass through. Cut and frame the wall pass through
opening.
5. Place the interior wall thimble into the 10” x 10” wall
pass through. Secure it with 4 screws (not provided).
Install the exterior portion of the thimble in similar
fashion, overlapping the 2 sections.
Caution: For buildings with vinyl siding,
install a vinyl siding standoff between the vent
cap and the exterior wall.
6. Install the horizontal vent termination on the outside of
the wall. Ensure both of the retaining straps extend
through interior wall thimble. Before attaching the vent
termination to the outside of the house, run a bead of
non-hardening mastic around its’ outside edges to
ensure a good seal between it and the wall. Ensure the
arrow on the end cap points up. Secure the cap to
the wall with appropriate screws.
7. Move the stove and vent pipe into position. Make sure
the 12” vent pipe extends into the horizontal vent cap a
minimum of 1-1/4”. Secure the vent using the straps
from the horizontal vent termination to the interior 6”
pipe with 2 sheet metal screws, keeping the screws as
close to the wall thimble as possible. Bend or cut any
excess strapping, so that it is not visible after the
installation is complete.

ELECTRICAL CONNECTIONS
NOTE: Open the valve compartment door on the
lower front of the unit to access electrical and gas
connections.
REMOTE CONTROL THERMOSTAT
The Luno 8160 comes equipped with a programmable
ON/OFF/Thermostat remote control. We recommend
the use of the thermostatic remote for more
comfortable performance, however you may still
override the thermostat by setting the switch to “ON”.
The thermostat controls the unit by “calling for heat.”
The thermostat turns the unit on when the room is
cold, and turns the unit off once the room is warmed
sufficiently. If desired, you can use any wired wall
thermostat in place of the remote. You cannot use
both the remote and a wall thermostat
simultaneously.
REMOTE THERMOSTAT PLACEMENT
Place the thermostat transmitter in the same room or
living space as the unit. Since the transmitter is the
device measuring the temperature, you will want to
keep it off the floor and away from any influences that
may cause the temperature in the vicinity of the
thermostat to be unrepresentative of the room
temperature in general. Such influences might include
strong lighting, a heater vent from the central heating
system, or a nearby sunny or drafty window.
Do not place the thermostat transmitter directly
behind or too close to the unit, otherwise heat from
the unit will immediately satisfy the thermostat and
turn the unit off.
WIRING INSTRUCTIONS
CAUTION: Label all wires prior to
disconnection when servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify proper operation after servicing.
(
Attention: Au moment de l’entretien des
commandes, étiquetez tous les fils avant le
débranchement. Des erreurs de câblage peuvent
entraîun fonctionnement inadequate et
dangereux.

Figure 6: Gas Control Valve
GAS SUPPLY &CONNECTIONS
NOTICE: A qualified technician must connect the
heater to the gas supply and leak test the unit before
it is approved for use. Consult all codes.
WARNING: THE UNIT MUST BE INSTALLED
AND CONNECTED IN ACCORDANCE WITH LOCAL
CODES, OR IN THE ABSENCE OF LOCAL CODES,
WITH THE MOST CURRENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1 (NFPA
54) OR CAN/CGA B149 INSTALLATION CODE.
NFPA Code and Hearthstone require the use of a
dedicated sediment trap just upstream of the unit.
Damage to the valve or other components, due to the
lack of a sediment trap
(figure 10) , are not covered by
warranty.
GAS CONNECTIONS
The gas supply connection is made to the Luno’s gas control
valve at the middle, lower rear of the stove, using a 3/8”
male NPT fitting. The supply line should be ½” diameter, or
appropriately sized to provide a sufficient gas supply to
meet the maximum demand of the unit without undue loss
of pressure. We recommend a flexible line to avoid undue
mechanical load on the valve and to ease thread alignment,
but refer to local codes.
CAUTION: Check Gas Type!
GAS SUPPLY
Isolate the Luno from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or greater than ½ psig. Disconnect the
Luno and its individual shut-off valve from the piping system
when testing the valve and connections at pressures equal
to, or greater than ½ psig.
GAS PRESSURE ADJUSTMENT
NOTE: A QUALIFIED TECHNICIAN MUST
PERFORM THIS PROCEDURE!
Once connected to the gas supply, the supply line and
manifold gas pressures must be tested. The supply line
pressure is tested, to ensure it meets the minimum gas
supply pressure as listed in the Specifications for the type of
fuel in use (natural gas or LP), by connecting a manometer
to the supply line and adjusting the incoming pressure if
necessary to meet the required supply line pressure as listed
in specifications. The manifold pressure tap on the gas
control valve, refer to
Figure 8 for location.

FIRE LOG PLACEMENT
CAUTION: Fragile! Handle log set with care.
Always wear gloves and safety goggles while
handling the log set.
Place only the Fire log set supplied with the Luno in the
firebox. Do not place any other logs, wood logs, or other
materials in the firebox. If the log set is damaged or broken
contact your dealer for replacement. Only replace the logs
with the same approved replacement parts. These
components affect the combustion quality and safety of the
heater. The Fire log set is durable; however, they will break
if subjected to rough or improper handling. Exact positioning
of the log set is required in order to obtain a pleasing flame
pattern and efficient combustion. Incorrect log placement
may cause carbon build-up; excess thermal stress on the log
set and stove parts, reduced efficiency, and high levels of
carbon monoxide. If the log set does not fit into the firebox
exactly as outlined, contact your dealer for assistance.
INSTALLATION OF THE FIRE LOG SET
Follow the order of the following photos in order to install the
log set:
1. Install the rear left log in the rear left corner.
2. Locate and install the rear right log.
3. Locate and install the ember pile. This will have two
holes underneath that fit over two posts in the center of
the burner top.
4. Install the Center log. The bottom tip rests in the cradle
of the ember pile.
5. Place the left front ember strip in front of the pilot
assembly.
15

HearthStone Quality Home Heating Products, Inc. LUNO 8160 Gas-Fired Direct-Vent
6. Slide the Right front ember strip next to the Left ember
strip. The two fit together to hide the seam.
7. Sprinkle the charcoal embers over the burner ports.
Ensure that you leave the ports open over the pilot and
where the main burner ignites.
8. Place the twig as shown.
9. Place Platinum Bright embers randomly and sparingly
over the logs and burner.
REMOVAL OF LOG SET
CAUTION: THE FIRE LOG SET RETAINS HEAT AND
CAN BE VERY HOT! ALLOW 2 TO 3 HOURS AFTER
PILOT LIGHT IS TURNED OFF BEFORE HANDLING.
To remove the Fire log set, follow the Installation of Log Set
instructions in the reverse order.
LIGHTING THE UNIT FOR THE FIRST TIME
WARNING: If you do not follow these
instructions exactly, a fire or explosion may result
causing property damage, personal injury or loss
of life.
CAUTION: Lighting the Luno for the first time
and adjustments to the unit should be performed
by qualified service personnel.
This appliance is designed only for use with the type(s) of
fuel gas indicated on the rating plate. This appliance is not
convertible for use with other gases, unless a certified kit is
used.
Cet appareil doit être atilisé uniquement avec les types de
gas indiqués sur la plaque signalétique. Ne pas l’utiliser avec
d’autres gas sauf si un kited conversion certifié est installé. )
SMOKE AND FUMES WARNING
When lit for the first time, the Luno will emit some smoke
and fumes. This is normal “off-gassing” of the paints and
oils used in the manufacturing and assembly of the unit.
Open windows to vent the room if necessary. The off gassing
and fumes will subside after the first 10 to 20 minutes of
operation.
ODORS AND IMPURITIES
A heater of this type may produce other odors during heater
operation due to impurities that may exist in the immediate
area. Sources of impurities can be cleaning solvents, paint
solvents, cigarettes, candles, smoke, pet hair, dust,
adhesives, new carpet, and/or textiles. Such odors usually
dissipate. However, opening a window or otherwise providing
additional ventilation to the area can alleviate the condition
quickly. If any odor persists, remove potential sources, or
contact your dealer or an authorized service technician.
PILOT LIGHT
The Luno has a piezoelectric spark igniter (the black push
button located next to the gas control valve behind the valve
access door), which ignites the pilot light by means of a
spark at the pilot light assembly.
DO NOT LIGHT PILOT OR BURNER BY HAND
Never attempt to light the pilot or main burner by hand with
a match or lighter. If, after repeated attempts, the pilot light
fails to light using the piezoelectric igniter, discontinue
operation; turn off the gas at the gas control valve, and
immediately contact qualified service personnel for
assistance.
PREPARE FOR LIGHTING
Prepare for the lighting procedure by adjusting the
thermostat (if equipped) to its lowest setting or OFF position.
If the gas control knob is not in the OFF position, turn the
knob fully clockwise to OFF. Locate the variable output
control knob and turn it fully clockwise to the highest setting.
Prior to lighting the unit for the first time, wait 5 minutes to
allow any residual gas within the unit to dissipate. Smell all
16

HearthStone Quality Home Heating Products, Inc. LUNO 8160 Gas-Fired Direct-Vent
around the appliance area for gas. Be sure to smell next to
the floor because some gases (LP) are heavier than air and
will settle on the floor. If you do not smell gas after this five-
minute period, proceed with the lighting procedure. If you do
smell gas, DO NOT proceed with the lighting procedure.
Instead, immediately refer to the ‘What to Do If You
Smell Gas!’ warning on the cover of this manual.
NOTE: The valve control has an interlock device.
After shutting off all gas flow, the pilot burner cannot be
relit until the thermocouple has cooled, releasing the
electromagnet (approx. 60 seconds). The gas control
knob is designed to operate by hand. Do not use any
tools during this operation. Damaged knobs may result
in serious injury.
INITIAL ADJUSTMENTS
Once the Luno is set in place, connected and assembled as
described in the “Clearances To Combustibles”, “Venting
Components & Configurations,” “Electrical Connections”, and
“Gas Supply and Connections” sections of this manual, the
unit is almost ready to light for the first time. The
manufacturer tests each unit prior to shipment, so ignition
should take place without failure. However, a number of
small adjustments may be necessary to compensate for
variations in gas pressure, altitude, and other factors
particular to each installation.
VARIABLE OUTPUT CONTROL
The gas control valve is equipped with a variable output
control. This control varies the rate of heat produced by the
unit by varying the gas pressure to the TEK Burner. A
combination of heat output and the thermostat setting affect
the length of the burn cycle. If your stove cycles on and off
too often, first try reducing the burn cycle by turning the
HI/LOW knob, on the control valve, to a lower setting. Using
the variable output control, the heat output of the unit can
be reduced for mild fall and spring months, or maximized for
the colder winter months. This adjustment can be made by
the homeowner as necessary by turning the variable output
control knob to “HI”, “LO” or any setting in between.
LIGHTING INSTRUCTIONS
NOTE: The gas control knobs and the piezo igniter are
located behind the control valve access door, under the front
of the unit.
1. STOP! Read the What To Do If You Smell Gas!
Warning (on the cover of this manual). Ensure the
front door is closed, and the lock screws are in
place.
2. Set the on/off/remote switch or thermostat to the “OFF”
position.
3. Push in and turn the gas control knob clockwise to
“OFF”.
(If not previously lit, the knob should be in this
position.)
4. Wait (5) five minutes to clear out any gas. If you then
smell gas, STOP!
Smell all around the appliance area for
gas. Be sure to smell next to the floor because some
gases are heavier than air and will settle on the floor. If
you smell gas immediately follow the ‘What To Do
If You Smell Gas!’ warning on the cover of this
Manual. If you do not smell gas, proceed to the next
step.
5. Turn gas control knob counter-clockwise to “PILOT”.
6. Push in the control knob all the way and hold in.
Immediately light the pilot with the gas lighter (push in
and “click” the piezoelectric spark igniter button several
times until lit). Continue to hold the control knob in for
about 20 seconds after the pilot is lit. Release the knob
and it will pop back out. The pilot should remain lit. If
the pilot goes out, repeat the operation.
If knob does not pop out when released, stop,
shut off the gas supply to the heater and
immediately call a qualified service technician or
gas supplier.
If the pilot will not stay lit after several tries,
turn the gas control knob “OFF” and call a
qualified service technician or gas supplier.
7. After the pilot lights, turn the gas control knob counter-
clockwise to “ON”.
8. If the ON/OFF/remote switch is set to “ON”, the stove
should now light. If the remote (or thermostat) is
installed, set the ON/OFF/ remote switch to “remote”
and program the remote to “ON”. Then set the desired
temperature.
9. Shut the gas control valve access door.
10. If “Remote” was selected, set remote to “ON” and set
desired temperature setting. Normally, if Remote
position was selected, the main burner is cycled on and
off by the thermostat or the “on/off” switch located on
the bottom of the thermostat body.
NOTE: When pressing/clicking the piezoelectric spark
ignition button to light the pilot, watch through the glass
(front) of the unit. Click the igniter button until a flame is
visible at the pilot. Once the pilot is lit, continue to press on
the gas control knob for another 20 seconds, then release.
Ascertain that the pilot is still lit by looking through the front
door. If lit, then turn the gas control knob fully counter-
clockwise to the “ON” position. If the pilot fails to light, or if
it went out due to a premature release of the gas control
knob while depressed in the “PILOT” position, wait 60
seconds for the Interlock to release. Then repeat the lighting
process as described in this section of the manual.
Once the pilot is lit, the gas control knob is been turned to
the “ON” position, and the ON/OFF/Remote switch is turned
to “ON”, the main burner should light immediately. If you
would like to use the thermostat and it is installed, switch the
ON/OFF/Remote switch to thermostat. Turn the remote
transmitter to "ON" and set it to a higher position so that it
"calls" for heat in order to light the main burner (i.e. turns
the unit on). Note that the remote thermostat controls the
on/off cycling of the main burner, but the pilot remains lit
regardless of the remote thermostat setting. The only way to
turn the pilot off is to turn the gas control knob fully
clockwise to the “OFF” position.
17

HearthStone Quality Home Heating Products, Inc. LUNO 8160 Gas-Fired Direct-Vent
TO TURN OFF GAS TO APPLIANCE
1. Set the Remote thermostat to the “OFF” position or turn
the ON/OFF/REMOTE switch to the “OFF” position.
2. If shutting the unit off for the non-heating season, turn
the gas control knob fully clockwise to the “OFF”
position. Do not force the knob to turn.
AIR SHUTTER
The air shutter is used to regulate the air-to-gas combustion
mixture, which in turn influences the size and color of the
flames. The air shutter is factory set in the general location
needed for Natural Gas (NG), however, if the unit is not
burning as well as it should, then the air shutter may need
adjusting. The air shutter may need adjustment once the
unit has been installed to compensate for variations in supply
line pressure, restriction plate position, altitude, fuel gas type
conversions, and other variables.
To determine if the air shutter needs adjustment, it is
necessary to view the flame pattern with the variable output
control knob at its highest setting. Allow the unit to operate
for at least 10 minutes to allow the entire unit to reach
temperature, and for the flame pattern to stabilize.
Generally, the more air (open shutter) in the mixture, the
bluer the flame. Less air (closed shutter) results in a more
yellow flame, but too little air will result in incomplete
combustion, low efficiency and a dirty burn. There are two
simple guidelines to aid in determining the correct flame
pattern:
If the flame at the base of the logs is completely
blue, the air shutter is possibly open too far;
If the flame is dirty (sooty) or licks the top of the
stove, the air shutter is possibly closed too far.
Some conditions cannot be corrected through air shutter
adjustment; an adjustment must be made to the gas supply
pressure or by changing the restriction plate location.
Qualified service personnel must perform supply
line/manifold gas line pressure adjustments and restrictor
plate adjustments. Do not attempt to complete any part of
the installation or adjustment of this unit unless technically
qualified to do so.
AIR SHUTTER ADJUSTMENTS
The air shutter adjuster, located under the valve access door,
at the lower front of the unit, is adjustable while the stove is
burning. Under the burner assembly, but above the valve is
the air shutter handle. It is a steel handle bent down for you
to grasp. It uses a thumbscrew to lock the position of the
shutter in place. This handle and screw will get very hot
during operation. Loosen the thumbscrew and slide the
shutter back and forth a couple of times to understand the
“throw” of the shutter. Push the handle forward to close the
air shutter. Pull it towards you to open the air to the unit.
When the flame pattern is correct, tighten the locking nut
without turning the screw. The air shutter is factory set and
only a qualified gas technician should make adjustments.
Note: Very little movement is needed to substantially
change the burn and flame patterns. Some conditions cannot
be corrected through air shutter adjustment; an adjustment
must be made to the gas supply pressure. Supply
line/manifold gas line pressure adjustments must be
performed by qualified service personnel. Do not attempt to
complete any part of the installation or adjustment of this
unit unless technically qualified to do so.
PILOT ADJUSTMENT
The pilot light is preset by the manufacturer and should not
need adjustment. However, you should perform a periodic
visual check of the pilot flame. The pilot light flame should be
large enough to engulf the thermopile and thermocouple
located next to the pilot, but not so large as to create
excessive noise or consume excessive gas
(Refer to figure
10)
. If needed, the pilot flame is adjustable by means of the
pilot light adjustment screw located on the gas control valve
(see figure 8) . Open the valve door to access the pilot
adjustment screw. Note that the pilot flame must engulf the
thermopile so that the thermopile can generate sufficient
milli-voltage (325 to 500-mv) to power the gas control valve.
The flame on the pilot should look like
Figure 10 . Controlling
the Luno by the remote or wall-mounted thermostat may
become erratic, nonexistent, or the unit may go out, if the
pilot flame is too small or misdirected away from the
thermopile.

WARNING
The control has an interlock device. If the stove was lit,
then turned off, it will not relight immediately. After
shutting off all gas flow, the pilot burner cannot be relit until
the thermocouple has cooled, releasing the electromagnet
(Approx. 60 sec.) . The gas control knob is designed to
operate by hand. Do not use any tools during this operation.
BURNER FLAME APPEARANCE
Once the unit is lit, observe the flame pattern and adjust as
necessary. You should perform a periodic visual check of the
burner flame. The burner flames can be adjusted by means
of the air shutter. To determine if the burner flame needs
adjustment, it is necessary to view the flame pattern with the
variable output control knob at its highest setting (turn fully
clockwise). Allow the unit to operate for 10 minutes enabling
18

HearthStone Quality Home Heating Products, Inc. LUNO 8160 Gas-Fired Direct-Vent
the entire unit to reach temperature and for the flame
pattern to stabilize. The flame pattern should be similar to
the one shown in
Figure 11 . There are several guidelines to
aid in determining if the flame pattern is correct:
1. The flame should not be dirty, smoky, sooty, or lick the
top of the stove.
2. The flame should not rise off the burner; this is called
“lifting”.
3. Flames should not impinge heavily on the log set. They
should “fit” through the pre-formed spaces designed in
the log set.

ROUTINE MAINTENANCE AND CARE
The Luno requires minimal routine maintenance and care.
Ensure the Luno is cool and off when being cleaned, or
serviced. Once a year, the unit, and venting system should
be inspected by qualified service personnel to insure that
they are clean, free of obstruction, safe, and in good working
order. If service or maintenance is required, qualified service
personnel should perform it.
WARNING: Do not substitute materials. For
replacement parts, or for information about parts or service,
contact your local Hearthstone dealer.
CLEANING
WARNING: Do not clean the unit when hot.
The unit should receive regular cleaning on, under, and
around the stove to prevent the buildup of dust and lint. The
exterior surfaces of the unit can be cleaned using soap,
water, and a soft cloth. Do not use abrasive or chemical
cleaners and take care not to scratch the glass or enamel
finish (if so equipped) when cleaning the unit. The use of
chemical wax based cleaners or polishes are not
recommended due to the potential for discoloration of the
stones, castings or enamel when the residues of the cleaners
or polishes are exposed to heat. Excessive buildup of dust,
spider webs, or room air contamination may cause odors
when the stove is hot.
FIREBOX,PILOT,&BURNER ASSEMBLY
The firebox requires periodic cleaning to prevent the
accumulation of dust, lint, and other debris. To clean the
firebox, set the ON/OFF/REMOTE switch to the “OFF”
position, and turn off the gas at the gas control valve. When
the unit is cool, open the front door. Carefully remove the
decorative log set, taking care not to damage the logs or
chip the enamel cast iron. Clean the firebox and burner, and
carefully vacuum the entire surface of the log set.
Thoroughly vacuum the ports (holes) along the top of the
burner, and the pilot assembly.
With the decorative logs out of the firebox; briefly light the
unit. Check to insure a proper flame is burning from each
burner port. The pilot flame should be large enough to engulf
the thermopile and thermocouple as shown in
Figure 10.
NOTE: Do not operate the unit for more than 1-2
minutes without the log set in place. Turn the unit off
by setting the thermostat to “OFF”, and turning the gas
control valve off. Allow the unit to cool.
Check and clean any burner ports that are not burning, or
not burning properly. Clean burner ports using a soft brush
or vacuum cleaner. If the pilot flame height needs
adjustment, it should be adjusted by qualified service
personnel as described on
page 18 .
Complete the cleaning procedure by carefully placing the log
set within the firebox. Re-install the glass assembly and front
cast. Turn on the gas, light the unit and check for proper
operation. Flame patterns should look similar to the flames
in
Figure 11 . Regularly check to insure the area around the
Luno is kept free from combustible materials, gasoline, and
other flammable vapors and liquids. Check that the flow of
combustion and ventilation air is not obstructed.
DOOR REMOVAL PROCEDURE:
The door is held closed with two machine screws, one on the
top above the door, and one below the lower right corner of
the door. To access these screws you must remove both the
top stone and open the lower control access door located
just below the front door. Do not remove the stone leveling
screw containing the brass lock nut. Use the provided tool to
release the pressure on the screws before removal. Remove
the mounting screw using a 4mm or 5/32” Allen wrench.
1. Open the door fully, grasp the door securely and support
it, remove the upper hinge pin.
2. Tilt the top of the door outward, and then lift the door
up off the lower pin.
3. Place the door face down on a padded work surface.
Use two rolled up towels, or similar, under the door to
stabilize the curved door during maintenance.
4. Reverse steps 1 and 2 when remounting the door.
Reinstall the securing screws when the door is closed
for operation; the door will not seal without them. Use
the provided tool to apply pressure on the door seal before
installing the screws.

GLASS REPLACEMENT PROCEDURES: GLASS CLEANING
As fuel gas may contain some impurities; it will be necessary
to clean the inside of the glass occasionally. Do not use
abrasive cleaners. Scratching the glass will weaken the
integrity of the glass. Do not clean the glass when hot!
Allow the glass to cool and apply a mild window cleaning
fluid. Special gas appliance window cleaner is available from
your local Hearthstone dealer.
1. Follow the instructions included with the replacement
glass kit.
2. Remove the door (see door removal procedure).
3. Remove the 12 screws from the glass retainer (use
penetrating oil if necessary) – lift the retainer off the
glass. Set aside for reinstallation.
4. Carefully lift the damaged glass out of the door and
discard. WARNING: Do not operate this appliance with
the glass panel removed, cracked, or broken. Do
not subject the door to abuse, such as striking or
slamming shut. Replacement of the glass panel
should be done by a licensed or qualified service
person.
5. Remove any remaining glass and old gasket material.
6. Clean the screw holes and place a small amount of anti-
seize compound in each one.
7. Place the gasketed new glass onto the door.
8. Important! Center the glass and ensure that the
edges of the curved glass are parallel with the edges of
the opening.
VENTING
9. Check glass position again (centered, and parallel), then
screw the glass retainer back on the door using a
crisscross pattern. Tighten the screws no more than
1/8th of a turn after they seat. (The glass will break at
this point if not positioned correctly. If the glass shifts
too much to one side, you may see the gasket from the
outside)
The venting system should receive a periodic examination by
a qualified agency. If the vent-air system is disassembled for
any reason, re-install per the instructions provided in the
venting section of this manual, being sure to reassemble and
reseal the venting properly.
STONE
10. Apply a light film of anti-seize lubricant on the door’s
hinge pins if needed.
Occasional cleaning is all that is necessary to maintain the
natural beauty of your stove’s soapstone top plate. Clean the
soapstone with water, any non-abrasive cleaner and a soft
cloth. Wipe dust from the stone with a clean cloth. Do not
use chemical agents to wash the stone; do not use waxes or
any polishing agents on the stone. Soapstone is porous and
will absorb most liquids, which can leave a stain, change the
appearance, or result in odd odors when warm.
11. Install the door.
12. After 5 or 6 fires, check the glass retainer screws, and
retighten if necessary.
Required Glass Kit: Part Number: 3300-201477 (Glass with
gasket applied).
Take care not to scratch or chip the soapstone. Do not set
items that can scratch or chip the stone on top of your stove.
You can use 240 grit sandpaper to easily repair, or blend in
minor scratches
Often, with use and over time, subtle earth tones of brown,
red, and yellow may appear in the soapstone. This is a
natural reaction in the soapstone. Surface or hairline
fractures may also appear in the stone after a stove is used.
Such changes are normal and do not affect the operation or
the integrity of the stove and do not require replacement. If
you observe a completely broken stone, contact your dealer
for service.
