PLANNING YOUR INSTALLATION
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL
A correct installation is critical and imperative for reduc-
ing fire hazards and perilous conditions that can arise
when wood pellet burning appliances are improperly
installed. The installer must follow all of the manufac-
turers’ instructions.
INSTALLATION / MAINTENANCE STANDARDS
National Fire Protection Association – The primary
NFPA standard that refers to installation and mainte-
nance of pellet appliances and venting is NFPA 211 –
Latest Edition: Chimneys, Fireplaces, Vents, and Solid
Fuel appliances.
The installation of this appliance must conform to local
codes and applicable state and federal requirements.
Familiarity with these requirements before installation is
essential. Important considerations to discuss with local
building officials include:
SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A pel-
let stove depends primarily on air circulation (convec-
tion) to disperse its heat, and therefore, a central loca-
tion is often best. There are other practical considera-
tions, which must be considered before a final selection
of locations is made.

Applicable codes (i.e. Uniform Mechanical Code,
State or Regional Codes).

Aesthetic Considerations
Roof Design (rafter locations & roof pitch)
Room Traffic
Proximity to Combustibles
Electrical Wiring
Power Supply Requirements – The power cord must
be plugged into a standard, 115 volt, 60 Hz grounded
electrical outlet. The approximate power requirement is
362 Watts, and will peak up to 736 Watts for approxi-
mately 6 minutes when the self-igniter is operating (it
will turn off 2 minutes after flame detection). The power
cord must be routed to avoid contact with any of the hot
or sharp exterior surface areas of the stove. When in-
stalled into a manufactured (mobile) home, the appli-
ance must be electrically grounded to the steel chassis
(see page 8, Manufactured [Mobile] Home Require-
ments). These requirements must be met unless other-
wise specified by state or local authorities.
The installation of this stove will require some research.
Once your options are determined, consult with your
local building department who will be able to give you
the necessary installation requirements for your area (Is
a building permit required? Rooms where installation
may not be allowed, etc.).
WARNING: CHECK ALL LOCAL BUILDING AND
SAFETY CODES BEFORE INSTALLATION. THE IN-
STALLATION INSTRUCTIONS AND APPROPRIATE
CODE REQUIREMENTS MUST BE FOLLOWED EX-
ACTLY AND WITHOUT COMPROMISE. ALTERA-
TIONS TO THE STOVE ARE NOT ALLOWED. DO
NOT CONNECT THE STOVE TO A CHIMNEY SYS-
TEM SERVING ANOTHER STOVE, APPLIANCE, OR
ANY AIR DISTRIBUTION DUCT. FAILURE TO FOL-
LOW THESE INSTRUCTIONS WILL VOID THE
MANUFACTURERS WARRANTY.
WARNING - ELECTRICAL GROUNDING IN-
STRUCTIONS: THIS APPLIANCE IS EQUIPPED
WITH A THREE-PRONG (GROUNDING) PLUG
FOR YOUR PROTECTION AGAINST SHOCK
HAZARD AND SHOULD BE PLUGGED DI-
RECTLY INTO A PROPERLY GROUNDED
THREE-PRONG RECEPTACLE. DO NOT CUT
OR REMOVE THE GROUNDING PRONG FROM
THIS PLUG. DO NOT ROUTE POWER CORD
UNDER OR IN FRONT OF APPLIANCE.
SMOKE DETECTORS

Local amendments?
Is a permit required - cost?
You may wish to contact your insurance company
to ask if they require this.
Is outside combustion air required?
Rooms where the installation is not allowed?
Since there are always several potential sources of fire
in any home, we recommend installing smoke detec-
tors. If possible, install the smoke detector in a hallway
adjacent to the room (to reduce the possibility of occa-
sional false activation from the heat produced by the
stove). If your local code requires a smoke detector be
installed within the same room, you must follow the re-
quirements of your local code. Check with your local
building department for requirements in your area.

formula or r formula:
Common brick
Cement mortar
Ceramic tile
Marble
Example: Durock Cement is to be used for the floor protec-
tion. How thick must this material be? The following formulas
give the means of determining minimum thickness required.
~.05
Note: To convert inches to millimeters divide by .03937.
TM = minimum thickness required for alternate material
kM = k value per inch of alternate material
TL = minimum thickness of listed material
rM = r value per inch of alternate material
* After minimum thickness is calculated, the thickness can be no
less than 3/8” (.375” / 10mm).
(**) If the floor protector to be used is a noncombustible material and is
NOT listed on the chart above, the manufacturer of the material must
provide either the listed k-value per inch or r-value per inch and the
minimum acceptable thickness will need to be calculated per instruc-
tions on this page.

INSTALLING SURROUND ASSEMBLY - Advantage II-T
C INS (to be done after venting system is installed)
The surround kit (purchased separately) comes with a set
of metal panels that enclose the fireplace opening when
fitted together. Put the surround assembly together accord-
ing to the following instructions (ref. see illustration below).
attached to the back of the Advantage II-T C INS. Tip: Be
careful to align the notched cutouts in the top surround
panel with the stove side panels. Adjust side to side if nec-
essary to align with the surround side panels.
10. Unwrap the control board carefully without touching
any electrical components. Holding the sides of the
control board, lower the bottom edge into the slot in
the bottom of the control door opening Install the
control board onto the right side panel (with door) us-
ing the #8 hex head screw provided.
1. Remove panels from package.
2. Verify that you have all three panels and a package with
“pop” rivets and #8 self-tapping screws. If you do not have
a “pop” rivet tool, you should arrange to buy or borrow one
for this installation.
3. Set the stove on the hearth so that the rear of the stove is
accessible to complete all pipe connections.
4. Verify that the hopper cover is all the way to the front and
open as high as your fireplace opening will allow. Secure
the hopper cover with at least two #8 screws on all three
sides. Tip: Spreading the side panels slightly may be nec-
essary to complete this step.
5. Place four rivets and your “pop” rivet tool beside the stove
and line up the right side panel (with control door) with the
holes in the side of the stove. (When the side panel is
properly installed, the hinge flange will be to the rear of the
stove.) Attach the panel to the stove with four “pop” rivets.
6. Secure the left side surround panel to the stove using the
procedure described in step #5.
11. Connect the wiring harness from the Advantage II-T C INS
into corresponding connector on control board.
12. Check the Advantage II-T C INS placement in the
fireplace. To reposition, open the door and make any
needed adjustment by pulling forward and then push-
ing sideways. Once the unit has been centered to
your satisfaction, close the door and push the Advan-
tage II-T C INS back into place so the surround is
flush with the face of the hearth. Tip: Before com-
pleting this step, verify that the control board will not
hit the edge of the fireplace opening.
If using the optional gold surround trim, remove the trim
from its packaging and place the piece with the two mi-
tered ends along the top panel. Place the two remaining
side pieces on the surround so that the mitered ends

scissors, if necessary.
7. Before proceeding further, check pipe connections to en-
sure that all joints are sealed with high-temperature RTV
silicone and properly secured. Refer to detailed venting in-
structions on pages 16, 19 and 20.
8. The stove may now be pushed into the fireplace cavity to
within 1 1/2” of the face of the fireplace.
In factory built and masonry fireplaces, a means
must be provided to prevent room air passage to the
chimney cavity of the fireplace. This may be accom-
plished by sealing the damper area around the chim-
ney liner or pipe.

INSTALLATION
VENTING REQUIREMENTS
Horizontal Runs - The maximum total horizontal run
It is recommended that only an authorized dealer install
your pellet stove. The specified installation requirements
must be followed to ensure conformity with both the
safety listing of the appliance and local building codes.
All clearances, installation instructions and precautions
specified by the vent manufacturer must be followed.
must not exceed 10 feet (3.1 meters).
Horizontal run of pipe requires 1/4” (7 mm) rise per foot.
Pipe Clearances / Requirements - See pipe manufac-
turers instructions for installation of venting components
and clearances. Follow pipe manufacturers installation
precautions for passing pipe through a combustible wall
or ceiling (i.e. use an approved thimble). Note: Pellet
vent pipe requires 3” (75mm) clearance from outside of
pipe unless otherwise specified by vent manufacturer -
all diameters: 3” (75mm) and 4” (100mm). A support
bracket must be installed every 4’ (1.2m) of pellet vent
pipe on the exterior wall of the house unless otherwise
specified by vent manufacturer.
Selecting a Location (Freestanding Models) - Review
the appliance clearance requirements before installing
the venting system (see page 6). Position the appliance
far enough away from walls to allow adequate room for
servicing. Choose the appliance location with the least
amount of interference with the house framing, plumbing,
wiring, etc.
Preferred Vent Configuration - For the best perform-
ance, we recommend a vent run design which runs verti-
cally and terminates above the roofline. This design will
allow natural draft to improve the flow of flue gases and
will aid in combustion and stove performance.
Pipe / Liner Joint Requirements - All pipe joints must
be secured with a minimum of 3 screws. ALL horizontal
joints must be sealed gas tight (air tight, sealed connec-
tion). Use RTV high temperature silicone or Interam to
provide a complete seal at the flue collar and on all
joints.
Type of Pipe - This stove requires type “PL” vent pipe
(pellet vent pipe, sometimes referred to as “L-Vent pellet
vent”), listed to UL 641 or ULC S609. Connect the pellet
vent pipe or the “tee” to the flue collar using a minimum
of three screws and seal as specified in “Pipe / Liner
Joint Requirements” on this page. Do not use class B gas
chimney or single wall chimney as a substitute.
Connection to Masonry Chimney through a Wall
(Freestanding Models) - Be sure to verify the construc-
tion of a masonry chimney, as it may have combustible
framing.
Approved liner when relining Masonry or Factory
Built Fireplaces is 2100HT (degree F.) liner listed to
UL 1777 or ULC S635.
Size of Pipe - These pellet appliances are approved for
use with the following vent sizes: 3” (75mm) standard, or
4” (100mm), see page 15 - for determining correct size
vent). When 4” pipe is used: for horizontal vent installa-
tions use a 3” (75mm) to 4” (100mm) adapter - available
from vent manufacturer. For vertical installations use a
3” (75mm) to 4” (100mm) “tee” - available from vent
manufacturer.
Connection to an Existing Class A Chimney (Free-
standing Models) - A chimney adapter can be used to
make the connection from 3” (75mm) or 4” (100mm) pel-
let vent pipe (listed to UL 641 or ULC S609) to existing
UL chimney system. Verify with the pipe manufacturer
that your pipe brands will interconnect.
Note: If installation requires in excess of 11 feet (3 1/3
meter) of pipe, it is recommended that 4” (100 mm) pipe
be used.
Horizontal-Vent Installations - On all horizontal-vent
installations (short, horizontal runs with no vertical pipe);
care should be taken when choosing a location for termi-
nating the vent. It is not recommended to directly vent
the exhaust on the prevailing wind side of the house. It is
recommended that when an appliance is vented directly
through a wall, a minimum of 8’ (2.5m) of vertical pipe
should be installed to create some natural draft. This will
reduce the possibility of smoke or odor entering the
dwelling during appliance shutdown or loss of power.
Offsets - In every installation, a single or double clean-
out “tee” is recommended for every ninety-degree offset
(this tee will help collect ash residue and will allow for
routine cleaning without the need to disconnect sections
of pipe). Note: Offsets and horizontal runs accumulate
fly ash and soot which reduces the exhaust flow and per-
formance of the stove.
Total Offsets in venting system should not exceed 270°
total in direction change.

VENT TERMINATION
Site Built Residential Home
Do not terminate vent in an enclosed or semi-enclosed
area such as: carports, garage, attic, crawl space, under
a deck, porch, narrow walkway, closely fenced area, or
any location that can build up a concentration of fumes
such as a stairwell, covered breezeway etc.
Chimney Height Requirements
The vent termination height required is - USA, 1-foot
minimum; Canada 3-feet minimum above the roof pene-
tration point as illustrated below (Ref. USA - National
Standard, NFPA 211, Clause 7-4.1 and Canada National
Standard CSA B365-01, Clause 5.6). Check with your
local building official for additional requirements for your

C. Not less than 2’ (.6m) from combustible materials
such as an adjacent buildings, fences, protruding
parts of the structure, roof overhang, plants and
shrubs, etc. and not less than 7’ (2.1m) above grade
when located adjacent to the public sidewalks (ac-
cess). The final termination of the exhaust system
must be configured so that flue gases do not jeop-
ardize the safety of people passing by, overheat
combustible portions of nearby structures or enter
the dwelling.
D. Not less than 3’ (.92m) below an eave (maximum
overhang of 3’ (.92m) or any construction that pro-
jects more than 2” (51mm) from the plane of the wall.
E. The distance from the bottom of termination to grade
is 12” (305mm) minimum. This is conditional upon
plants and nature of grade surface: Be careful to
choose a location for the vent termination which
does not expose people or shrubs to high heat from
the exhaust gases. The exhaust gases are not hot
enough to ignite grass, plants and shrubs located in
the vicinity of the termination although they should
be a minimum of 3’ (.92m) away. The grade surface
under the termination must not be a lawn.

F. Since sparks may escape from the exhaust pipe of
any stove, use caution when positioning the vent
pipe. Refer to pipe manufacturer’s instructions when
installing and terminating the exhaust. The vent pipe
should be horizontal and never run the pipe in a
downward direction (recommend a 1/4” (7mm) rise
per foot horizontal).
To pass inspection in nearly any jurisdiction, the chimney
must meet both safety and exhaust flow requirements.
The (3’ by) 2’ by 10’ rule applies to both masonry and
factory built chimneys.
Notes:
•
It is not recommended to terminate exhaust vent on
the prevailing wind side of the house.
* Ref. NFPA 211 Clause 7 – 4.1.2, Vents installed with a
listed cap shall terminate in accordance with the terms
of the cap’s listings.

4. Install listed type “PL” 45 degree elbow with optional
rodent screen or cap (recommended) on outside end
of pipe. The rodent screen should be no less than
1/2” (13 mm) mesh and may clog with soot and ash if
left unattended during the burn season.
INSTALLING YOUR FREESTANDING PELLET STOVE
Standard Horizontal Vent Installation
All PL Venting Components must be listed to UL 641
or ULC S609
1. Locate the proper position for the listed type “PL” wall
thimble. Avoid cutting wall studs when installing your
pipe. Use a saber saw or keyhole saw to cut the
proper diameter hole through the wall to accommo-
date the wall thimble. Use extreme caution to avoid
cutting into power lines within the wall of the home.
The hole size will depend on the brand of pellet vent
that you are using. Install the wall thimble in the hole.
2. ALL INTERLOCKING PIPE CONNECTIONS WITH-IN
THE ROOM MUST BE SEALED WITH HIGH TEM-
PERATURE RTV AND SECURED WITH A MINIMUM
OF 3 FASTENERS PER CONNECTION. Position the
stove approximately 12” (305 mm) from the wall on
the floor pad. Push the “PL” pipe through the wall
thimble. Squeeze a bead of high temperature silicone
(RTV) sealer around the end of the machined portion
of the 3” (76mm) pipe connector on the back of the
stove. Firmly push on a section of “PL” pipe until in-
ner pipe liner pushes into the bead of RTV sealer.
3. Push the stove with pipe attached towards the wall
(the pipe will go through the wall thimble). Do not
position the back of the stove closer than 2” (51mm)
from the wall (see clearances, page 6). Note:
Greater back wall clearance will improve the ease of
serviceability of the stove.
NOTE: The end of the exhaust pipe must extend a
minimum of 12” (305 mm) from the outside of the
building.
5. If the installation includes a source of outside com-
bustion air; cut a separate hole through the wall for
the fresh air tube. Use a galvanized or stainless steel
pipe for the duct. The minimum size for the duct
shall be not less than 50% of the cross sectional flue
area. Connect outside air pipe to air inlet on stove.
This tube must be terminated with a 45 degree elbow
or hood.
NOTES:
Combustion air may also be drawn from a vented crawl
space under the home.
All joints for connector pipe are required to be fastened
with at least three screws. If vented horizontally, joints
shall be made gas-tight (air tight, sealed connection) in a
manner as specified on this page (see instruction #2).
Install vent at clearances specified by the vent manufac-
turer.

ure to do so may result in the transfer of soot into the room by way of the Room Air Blower.
(USA Only) Venting Into an Existing Chimney
This pellet insert may be installed into a ma-
sonry fireplace (built to UBC 37 or ULC S628
standards) or a factory built fireplace (built to
UL 127 or ULC S610 standards) as illus-
trated on this page. When installing into a
masonry chimney, it is recommended that
the exhaust vent be extended to the top of
the chimney as shown on the following page.
However, if the vent pipe does not extend to
the top of the chimney, the vent must extend
a minimum of 18” above the damper. You
must seal the damper area so that the air /
exhaust in the chimney cannot communicate
with the air in the fireplace firebox (this is a
positive flue connection. See the following
instructions for one method of sealing flue).

CARE AND OPERATION
CONTROL BOARD OPERATION
Control Board
Start Button – The push button Start Button activates
the room air and the exhaust blowers. If the exhaust
temperature does not reach operating temperature within
30 minutes, the stove will automatically shut down. The
blowers can be restarted by pushing the Start Button
again.
Auger On/Off Button – The Auger On/Off Button acti-
vates the fuel feed (auger motor) only. The light located
just above the button will blink when the auger is turning.
The Start Button has to be activated to give power to the
Auger On/Off Button. When the Auger On/Off Button is
pressed a second time, the pellet feed will stop and the
blowers will continue to operate until the stove has
cooled sufficiently.
Heat Output Button – When not using a wall thermo-
stat, the Heat Output Button provides the ability to burn
at five separate settings. The Heat Output Button regu-
lates the fuel feed setting and the combustion air supply
simultaneously.
Blower Speed Button – The Blower Speed Button con-
trols the speed of the Room Air Blower. Pressing this
button will increase or decrease the amount of heat exit-
ing the stove. THE BLOWER SPEED MUST BE AT THE
MAXIMUM #5 SETTING WHEN THE HEAT OUTPUT
BUTTON IS ON THE #5 POSITION.
Combustion Air Trim – The Combustion Air (exhaust
blower) Trim is located just above the Heat Output Se-
lector button. Turning the Trim Control counterclockwise
will decrease the amount of combustion air entering the
UltraGrate. The Trim Control is factory set at the (0)
position.
Auger Trim Control – The Pellet Feed (Auger Trim)
Control is located just above the Auger On/Off Button.
Turning the Trim Control counterclockwise will decrease
the amount of fuel delivered to the UltraGrateTM. Turning
the control clockwise will increase the amount of fuel de-
livered to the UltraGrateTM. The trim control is factory set
at the (0) position.
NOTE: The trim controls should be adjusted for the
proper flame as a last resort. Always adjust the
damper control first. See Damper Operation, on
page 23.

CARE AND OPERATION
Fuel Delivery Rate
The Heat output button manages the fuel delivery rate by
controlling the amount of time the auger motor will run (Set-
tings:
1 = Low, 2 Medium Low, 3 Medium, 4 Medium High, 5
High).
GENERAL OPERATING CONSIDERATIONS
Proper Burn Characteristics: Your flame should be
bright yellow under normal operation. If your flame be-
comes reddish/orange, your stove probably needs rou-
tine maintenance. Excessive amounts of fly ash build-up
in the UltraGrateTM, clinkers in the UltraGrateTM, or leak-
age of air if the UltraGrateTM is not properly seated, will
starve the fire for air. (See ROUTINE MAINTENANCE
for information on cleaning the stove). If the problem
persists, review the trouble-shooting section at the end of
this manual.
PRE-LIGHTING INSTRUCTIONS
During an initial start-up, or in the case where the hopper
has run out of fuel, it will be necessary to prime the au-
ger feed system.
To prime the auger feed tube:
1. Fill the hopper with recommended pellet fuel and
plug the stove into the wall outlet.
Pellet Feed: The pellet feed system is designed to han-
dle a wide range of pellet sizes. Different pellets can
feed at considerably different rates. If the stove will not
stay lit at the minimum fuel feed setting, those particular
pellets may not be feeding fast enough. If this happens,
adjust the damper rod (on the side of the stove) in or out
to achieve a proper burn.
2. Press the START button on the control board to turn
on both blowers (the room air blower and exhaust
blower will run at start up settings or position #3).
Press the AUGER ON/OFF button on the control
board to start the fuel feed. Next, press the Heat out-
put button to position #5 (maximum feed rate).
3. Look through the combustion chamber door and
when you see the first pellets dropping into the Ul-
traGrateTM, the auger is then fully primed. It will take
10 to 15 minutes to prime the auger.
Pellet Size: You may notice a difference in the burn if
you change pellet fuel sizes. The bigger the pellet, the
slower it will feed and vice versa.
4. Once the auger is primed, press the AUGER
ON/OFF button to turn off auger.
STARTING YOUR PELLET STOVE
Long Burn Time: The stove may be safely operated on
a continuous basis, but it is recommended that it be
turned down overnight or when the room is vacated for
long periods of time.
1.
Make sure the auger is primed (see Pre-Lighting
Instructions above), then simply push the Start but-
ton on the control board to activate the igniter.
Press the AUGER ON/OFF button to the “ON” posi-
tion.
While the pellets will ignite on any heat output set-
ting, it is recommended that the Heat Output be set
to position #3. Pellets will start feeding into the Ul-
traGrateTM and should begin to ignite in approxi-
mately seven minutes. The self-igniter will auto-
matically shut off after fifteen minutes.
2.
3.
TURNING OFF YOUR PELLET STOVE
Press the AUGER ON/OFF button to the “OFF” position.
This will turn the auger motor off and pellets will stop feed-
ing. Both blowers will continue to operate for a period of
time (up to 45 minutes) until the exhaust temperature cools
sufficiently. The blowers will automatically turn off at that
point.
4.
After the pellets are burning well, press the HEAT
OUTPUT selector to the desired setting. Combus-
tion air and the pellet fuel feed rate will adjust auto-
matically as the HEAT OUTPUT selector button is
pressed. The flame should be bright yellow in color
and there should be no evidence of soot formation
at the top of the flame. Press the BLOWER
SPEED control to increase or decrease the desired
amount of room air from your stove.
Lighting Procedure Without Igniter: Start-up procedure
when Fastfire igniter has failed or been removed and
not replaced.
If your automatic ignition system should ever need trouble-
shooting, repair or replacement, please contact your au-
thorized Lennox Hearth Products dealer. Your stove can
be lit manually without using the automatic igniter in such
cases by following the procedure below.
5.
If operating your stove with the wall thermostat,
adjust the HEAT OUTPUT selector button to the
desired demand mode (#2 through #5 on the HEAT
OUTPUT selector button). Next, adjust the wall
mounted thermostat to the desired heat and your
stove will automatically switch between a demand
mode and a pilot mode.

CARE AND OPERATION
Continued from last page…
Damper Out (more air)
1. Place a recommended fire starter (see your dealer for
appropriate fire starter in your area) in the UltraGrateTM
and put a handful of pellets on top of the starter. DO
NOT USE FLAMMABLE LIQUIDS TO START YOUR
STOVE.
2 1/4”
Standard
2. Light the fire starter in the UltraGrateTM with a match
and close the door. Press the heat output selector but-
ton to position 3.
3. After approximately 10 seconds, press the START but-
ton. You will notice that the fire will become active and
there will be air coming from the heat exchanger tubes.
4. After the pellets in the UltraGrateTM are burning suffi-
ciently (red hot coals), press the AUGER ON/OFF but-
ton: this will activate the auger motor and pellets will
begin to feed into the UltraGrateTM. our blower motors
will continue to operate.
5. After the pellets are burning well, press the HEAT
OUTPUT selector to the desired setting. Combustion
air and the pellet fuel feed rate will adjust automatically
as the HEAT OUTPUT selector button is pressed. The
flame should be bright yellow in color and there should
be no evidence of soot formation at the top of the
flame. Press the BLOWER SPEED control knob to in-
crease or decrease the desired amount of convection
air from your stove.
The damper rod located on the lower left-hand side of
the stove will not need to be manually adjusted every
time you turn the fuel feed rate up or down. However, the
damper allows the air-to-fuel ratio to be “fine tuned.” The
proper air setting will vary from stove to stove depending
on installation configuration, altitude and type of fuels
being burned.
There is a “break-in” period for all Advantage II-T C
stoves. It is important to understand and make note of
the following items when you first light your stove:
•
During the first day or two of operation, it may ap-
pear that the flame pattern is somewhat short and
vigorous. This is due to the “break-in” period of the
auger motor.
If operating your stove with a wall thermostat, adjust the
heat output selector button to the desired demand mode
(#2 through #5 on the HEAT OUTPUT selector button).
Next, adjust the wall mounted thermostat to the desired
heat and your stove will automatically switch between a
demand mode and a pilot mode.
•
During this period, the auger motor will gradually
speed up its rotation cycle as the gearbox wears in.
This will correspondingly increase the fuel feed rate.
The flame pattern will grow accordingly, and the
damper rod may need to be pulled out slightly to
compensate.
DAMPER OPERATION
The Damper Rod is preset at 2 1/4” which is proper for the
average installation. In some cases the damper may need to
be adjusted from the standard setting.
•
DO NOT ADJUST THE CONTROL BOARD INTER-
NAL SETTINGS AT THE TIME OF INSTALLATION!
All adjustments to compensate for burn characteris-
tics should be done with the damper on the left-hand
side of the stove by moving it in or out slightly 1/4” at
a time.
Adjustment Procedure: Loosen setscrew on set collar
(see illustrations on this page), then adjust in 1/4" incre-
ments until optimum combustion air flow is achieved. For
less air push in and for more air pull out. After adjust-
ment, position set collar against side panel and tighten
setscrew.
When your new stove is installed; the exhaust should be
hooked up, the stove plugged in and the fire started.
Check for proper operation at all heat output settings (#1
- #5). Look for a brisk yellow flame with no black tips.

CARE AND OPERATION
Continued from last page…
Excessive Combustion Air: By closing the damper, this
will reduce combustion air delivery. Symptoms of exces-
sive air include; fuel burns too quickly (results in smoking
or smoldering pellets), white to yellow flame, etc. If the
damper is open too much, the burning pellets will lift off
the UltraGrateTM and fly up into the air much like popping
corn does.
Any adjustments for combustion air should be made at
the damper by varying the spacing between the side of
the stove and the inside of the damper set collar. The
factory setting on the damper, as noted above, should
correspond with the model you have.
Contributing factor:
If the fire goes out on the #1 setting, you will want to de-
crease the combustion airflow. Loosen the set collar and
push the damper in by 1/4” intervals. Tighten the collar
at its new position (2 1/2” – 2 3/4”).
•
Venting system providing excessive draft.
Correct Combustion Air / Proper Burn Characteris-
tics: When the damper is correctly set, the burning pel-
lets should move (wiggle) around slightly and the flame
should be bright yellow.
If the fuel is building up in the UltraGrateTM at the higher
heat output settings, you will want to increase the
amount of available combustion air. Loosen the set col-
lar on the damper rod and pull the damper out. Do this
1/4” at a time. Tighten the collar at its new position
(1 3/4” – 2”).
AUTOMATIC SAFETY FEATURES
Power Outage:
During a power outage, the stove will shut down safely. It
will not automatically restart when power is resumed un-
less the exhaust temperature is still hot enough. A small
amount of smoke may leak from the top of the window
glass, the hopper and from the exhaust air intake, if the
stove is vented horizontally with no vertical pipe. This will
not persist for more than 3 to 5 minutes and will not be a
safety hazard. It may set off your smoke alarm.
To re-light the stove, follow the normal procedure for
starting your stove.
After making any adjustment to the damper set collar,
pull the damper rod out fully and re-check the dimension
between the stove side panel and the inside of the set
collar.
NOTE: If the proper flame cannot be achieved with
the damper control, adjustment of the trim controls
may be necessary. See Control Board Operation on
Page 21 for information.
Note: If the area in which you live is prone to frequent
power outages, it is recommended that a minimum of 8
feet (2 1/2 meters) of vertical vent pipe be included in a
freestanding installation to induce a natural draft in the
event of a power failure.
DAMPER ADJUSTMENT GUIDELINE
Lack of Combustion Air: By opening the damper, this
will increase combustion air delivery. Symptoms of insuf-
ficient combustion air include; unburned fuel, lazy smoky
or red / orange flame, excessive ash or soot, excessive
buildup on glass.
Overheating:
A high temperature switch will automatically shut down
the stove if it overheats. The stove will need to be manu-
ally re-lit. Allow up to 45 minutes cooling time before re-
lighting. Keep enough convection air (room air blower)
going through stove to keep it cooling properly, this will
ensure long life of the stove. If the overheating continues,
contact your authorized Lennox Hearth Products dealer
for more information.
Contributing factors:
•
•
High Altitude – Lack of oxygen
Restrictive Venting (elbows, horizontal runs,
cold external chimneys, etc.).
Dirty / Poor Quality Fuel.
•
Note: Excessive amounts of fly ash built-up in the Ultra-
GrateTM, clinkers in the UltraGrateTM or leakage of air (if
the UltraGrateTM is not properly seated) will starve the
fire for air. See Routine Maintenance, on pages 26
through 30 for information on cleaning the stove.

CARE AND OPERATION
FUEL
Fuel Specifications - Using the UltraGrateTM burn sys-
tem, this appliance has been designed to burn wood
residue pellets with up to 3% ash content. Agricultural
pellets (i.e.… Corn, alfalfa etc.) are not permitted to be
burned in the stove. Dirty fuel will adversely affect the
performance of the stove.
Clinkering - Silica (or sand) in the fuel, along with other
impurities, can cause clinkering. A clinker is a hard mass
of silica formed in the burning process. Clinkering is a
function of the fuel, (not the stove), but adversely affects
the performance of the stove by blocking off the air pas-
sages in the UltraGrateTM. Even a P.F.I. approved pellet
fuel may tend to clinker. A clinker can be removed from
the UltraGrateTM and placed in the ash pan with the use
of the grate scraper / ash pan tool furnished with your
stove. See Routine Maintenance (on pages 26 through
30) for more information on cleaning.
Caution: The use of unapproved, dirty, wet and / or high
salt content fuel will void the warranty!
Wood pellets manufactured to the pellet fuels institute
(P.F.I.) certification standard are available in two grades,
Standard and Premium. The primary difference between
the two is the ash content of the pellets.
UltraGrateTM
The P.F.I., specification for standard grade & premium
grade residential pellet fuel is as follows:
•
•
•
•
CHLORIDES (Salt): Less than 300 p.p.m.
BULK DENSITY: 40 lb. / Cu. Ft. minimum
MOISTURE CONTENT: 8% maximum
ASH CONTENT: < 3% maximum (standard
grade) < 1% maximum (premium grade)
FINES: 0.5% maximum through a 1/8” screen
BTU CONTENT: Minimum 8200 BTU per pound.
•
•
Pellet Feed / Pellet Size - The pellet feed system is de-
signed to handle a wide range of pellet from .23” to .35”
in diameter and up to 1.5” in length. Different pellets may
feed at considerably different rates. You may notice a
difference in the burn if you change pellet fuel sizes. The
longer the pellet, the slower it will feed and vice versa. If
the stove will not stay burning at the minimum fuel feed
setting, those particular pellets may not be feeding fast
enough. If this happens, reduce the amount of combus-
tion air by adjusting the damper. See page 23 and 24.
Ash - The frequency of removal of the ash and mainte-
nance performed on the stove is directly proportional to
the ash content of the fuel and the operation duration of
your pellet stove. Low ash fuel may allow longer intervals
between cleaning, however, a stove burning high ash
fuel may need to be cleaned as often as everyday.
PLEASE NOTE: Lennox Hearth Products has no control
over the manufacturing of pellet fuel and will not be held
responsible for poor stove performance or any damage
caused by poor quality pellet fuels.
Long Burn Time - When operated correctly, this appli-
ance cannot be overfired. Continuous operation at a
maximum burn can, however, shorten the life of the elec-
trical components (blowers, motors, and electronic con-
trols), and is not recommended. Typical approved opera-
tion would include running at the low to mid range setting
with occasional running on the maximum setting during
the coldest periods of the winter. The blower speed con-
trol should be turned to high when operating the stove on
the high heat setting. A lower heat setting is recom-
mended for overnight operation or when the room is va-
cated for long periods of time.
Fuel Feed Rates - Different brands of pellets will feed at
varying rates due to their size and density (length and
diameter). This may require a slight adjustment in the
damper control (see pages 23 through 24).

ROUTINE MAINTENANCE
Inspect your stove or insert at minimum frequency stated until you establish a minimum frequency required for your
installation (frequency will vary depending upon fuel BTU value / ash content, usage, and misc. installation vari-
ables).
ROUTINE CLEANING
ASH PAN (Advantage II-T C FS)
Stove will need to be shut off and cooled enough to han-
dle before routine cleaning is performed. All ash removal
and cleaning should be done while stove is cold. Always
disconnect power before doing any routine cleaning.
The ash pan will have to be emptied periodically, de-
pending on the amount of fuel consumed. To access fol-
low steps one through four:
1. Open the glass door, then, using the ash pan / grate
scraper tool, lift the UltraGrateTM out and sweep the
top ash into the pan below.
Proper Disposal of Ashes
2. Remove the ash pan cover located below the door
by pulling forward until magnets release.
3. Pull the ash pan door knob and swing open.
4. Remove the ash pan using the ash pan / grate
scraper tool. (See picture below)
5. Place ashes into a non-combustible container. When
finished, close the glass door and slide the ash pan
back into the stove and close the ash pan door. Re-
install ash pan trim piece.
Ashes should be placed in a metal container with a tight fit-
ting lid. The closed container of ashes should be placed on a
non-combustible floor or on the ground well away from all
combustible materials pending final disposal. If the ashes
are disposed of by burial in soil or otherwise locally dis-
persed, they should be retained in the closed container until
all cinders have thoroughly cooled.
The following areas need to be inspected during Routine
Cleaning:
•
•
•
•
•
UltraGrateTM
Ash Pan
Ash Trap and Baffles
Heat Exchange Tubes
Exhaust Passages and Vent Pipe
UltraGrateTM
The UltraGrateTM should be inspected periodically to assure
that the air holes have not become clogged with ash or
clinkers. The UltraGrateTM can easily be cleaned with the
grate scraper tool, or it can be removed for cleaning. It is
very important to monitor the ash build up under the Ultra-
GrateTM, as excessive amounts of ash will block combus-
tion air from entering the UltraGrateTM, causing pellets to
pile-up in the UltraGrateTM. The ash build-up under the Ul-
traGrateTM is easily dumped into the ash pan by pulling out
the ash slide weekly as shown below. The UltraGrateTM
cleaning procedure is the same for all models.
Pull Forward To Remove Ash Pan Cover

ROUTINE MAINTENANCE
ASH TRAP AND BAFFLES
HEAT EXCHANGER TUBES
Access to the ash trap baffles (behind the two side fire-
bricks) is obtained by loosening the screws that hold the
Brick Retention Plates in place and lifting the clips away
from the stove. After the clips have been removed, re-
move the side bricks first, then the center firebrick. Thor-
oughly clean out the areas where ash has collected be-
hind the firebrick. The amount of time between clean-
ings will be directly related to the ash content of the pellet
fuel being burned. Excessive ash build up in the baffle
area behind the brick panels will restrict the exhaust pas-
sages and cause less combustion air to enter the firebox,
which can lead to poor performance and a "dirty burn".
ONLY CLEAN HEAT EXCHANGER TUBES AFTER
STOVE HAS COOLED DOWN.
A rod located above the combustion chamber door is
used for cleaning the tubes. Use the ash pan / grate
scraper tool to grab this rod and pull out and in several
times (see picture below). This will clean the fly ash off
the heat exchanger tubes. If your stove was recently
turned off, the rod may still be hot.
Use Ash Pan / Grate Scraper Tool To Pull And
Push Rod For Ash Removal From Heat Ex-
changer Tubes
Handy Hint: After the first 10-20 bags of fuel, you may
want to remove the firebrick and determine the rate at
which the fly ash is building build up within the Stove.
Contact your dealer for more information.

ROUTINE MAINTENANCE
EXHAUST PASSAGES AND VENT PIPE (All Models)
Inspect frequently and clean when necessary. Fly ash
will accumulate at all bends in the exhaust system. Note:
Large amounts of fly ash build-up will create a lack of
combustion air. Removing the clean out tee cap on verti-
cal installations will allow an inspection of the ash build-
up in the clean out tee and will help you to decide how
frequently more extensive cleaning must be performed.
DOOR ROPE GASKET (All Models)
The condition of the rope gasket around the door and
windows should be checked periodically and replaced or
repaired if necessary. A one-inch strip of paper may be
used to perform a test of the integrity of the door seal.
Close the door on the paper in at least eight points (see
illustration, “Door Rope Gasket”). It is normal to feel only
a slight amount of friction. The door gasket does not
need to be “tight” in all areas, since a small amount of
leakage is not hazardous or detrimental to the perform-
ance of your stove.

Minimum Frequency of 3 months to 1 year
Visually inspect gasket often. If it becomes frayed or
damaged it should be replaced.
CREOSOTE REMOVAL
When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture to
form creosote. The creosote vapors condense in the
relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited this creosote makes an extremely hot fire.
The chimney connector and chimney should be in-
spected at least once every two months during the heat-
ing season to determine if a creosote buildup has oc-
curred.
Minimum Frequency of 1-2 months
If creosote has accumulated it should be removed to re-
duce the risk of a chimney fire.

ROUTINE MAINTENANCE
WINDOW WASH
OPENING SIDE PANELS
Periodically remove four screws which secure the win-
dow wash bracket to the door frame, using a 1/4” socket.
Lift out the widow wash bracket, and set aside. Using a
small brush, sweep out all debris buildup from behind the
window wash bracket. After all debris has been removed
re-attach the window wash bracket.
Advantage II-T C FS – For right hand side panel open
the glass door, locate the 2 screws at front edge and re-
move using a 5/16” nut driver. Repeat procedure for left

REAR STOVE COMPARTMENT (All Models)
Swing Door Open
The rear stove compartment should be cleaned periodi-
cally (a minimum of once a year). DISCONNECT ELEC-
TRICAL CORD PRIOR TO CLEANING STOVE. Any
household dust, pet hair or sawdust should be vacuumed
or wiped out of the rear compartment of the stove, room
air blower, and combustion blower (paying special atten-
tion to vacuuming out the intakes of both blowers). The
electrical components should be wiped clean.

ROUTINE MAINTENANCE
SMALL AREA PAINT TOUCH-UP
MOTOR LUBRICATION
The stove body is painted with a quality high-
temperature stove paint. Use only Stove Paint, Part #
70K99. Do not touch-up your stove with any other paint.
Using one small piece of 320 grit sand paper and lightly
sand the blemish so that the edges are “feathered” or
smooth to the touch between the painted and bare sur-
faces. Do not let the sand paper gum up with paint, as
this will cause scratches on the metal surface. If there
are any scratches, use 600 grit sandpaper instead. Mask
off surfaces you do not want painted. Paint lightly over
the bare surface first as this will act as an undercoat.
Then paint over a larger area in smooth even strokes to
blend.
Room Air Blower: The room air blower is permanently
lubricated by the manufacturer. Do not apply oil to any
part of the blower, doing so may cause damage.
Exhaust Blower: The exhaust blower requires lubrica-
tion every 6 months or yearly, depending on use, with not
more than two drops of 30 weight, SAE, nondetergent oil
at the two lubrication points on blower.

COMPONENT DEFINITIONS
AIR WASH
detect reversed flow. If negative pressure in the
dwelling (i.e. An extremely tight house which may
not supply adequate combustion and ventilation air)
causes the exhaust to pull back from the combus-
tion air inlet, the heat from the exhaust will result in
heat activation of this disc.
To inhibit buildup of soot on the door glass, air is deliv-
ered to the glass through an air wash system located in
the doorframe surrounding the glass.
AUGER
It transfers the fuel down the burner tube into the firepot.
DISC, LOW LIMIT (Ceramic, F140-30F, N / O*)
This disc is designed to shut down the stove (auger mo-
tor and both blowers) if it does not sense the heat of a
fire.
AUGER MOTOR
Motor specifications are: .4 Amp, 1 rpm (revolutions per
minute). It drives the auger to deliver fuel to firepot.
BLOWER, ROOM AIR (CONVECTION)
The blower function is to transfer the heat from the appli-
ance to heat the room air.
HOPPER
The hopper is where the pellets are stored.
HEAT OUTPUT BUTTON
BLOWER, EXHAUST (DRAFT INDUCER/COMBUSTION)
It has a radial impeller to deliver more air to the firepot. It
pulls air into the firepot by creating a negative pressure.
This is done by extracting the exhaust gases out of the
firebox and pushing the exhaust downstream to the flue
exit.
This is the main power button, which controls power to
the feed system auger motor and Exhaust Blower. It has
5 feed rate settings, which controls the burn rate.
PRESSURE SWITCH
The Positive Pressure Switch is located on the Exhaust
housing and is designed to shut down the auger motor in
the event of flue blockage. Some other possible causes
are as follows:
DISCS, INLET & CONVECTION HIGH LIMIT
DISC, HIGH LIMIT (L250-30F, N / C)
There are 2 of these discs on this model. If a tempera-
ture reaches 250° F., the high limit auto reset will “trip”
and stop the flow of electricity to the auger motor. The
discs will not automatically reset until it has cooled below
220° F).
