PLANNING YOUR INSTALLATION QUESTIONS TO ASK LOCAL BUILDING OFFICIAL A correct installation is critical and imperative for reducing fire hazards and perilous conditions that can arise when wood pellet burning appliances are improperly installed. The installer must follow all of the manufacturers’ instructions. The installation of this appliance must conform to local codes and applicable state and federal requirements. Familiarity with these requirements before installation is essential.
PLANNING YOUR INSTALLATION Top View of Model: Optima 2 FS FLOOR PROTECTION - Optima 2 FS This appliance requires noncombustible floor protection. If the floor protection is to be stone, tile, brick, etc., it must be mortared or grouted to form a continuous non-combustible surface. If a chimney connector extends horizontally over the floor, the protection must cover the floor under the connector and at least 2" to either side.
PLANNING YOUR INSTALLATION FLOOR PROTECTION - Optima 3 FS The floor protector must Top View meet or exceed the *Up to 6” minimum thermal re1 53 mm minimum quirements as defined on this page (see Floor Protection/Hearth Extension Using Alternate Material As Floor Protector). If the floor pro- 6”/ 6”/ 153mm tection is to be stone, 153mm min. tile, brick, etc., it must min. be mortared or grouted to form a continuous noncombustible surface.
PLANNING YOUR INSTALLATION Clearances to combustibles are determined from testing to applicable standards for allowable heat transfer. The clearances allowed as shown here, do not take into account operation or serviceability requirements. CLEARANCES Optima 2 FS and Optima 3 FS - Standard residential or manufactured (mobile) home installation.
PLANNING YOUR INSTALLATION MASONRY AND FACTORY BUILT FIREPLACES The model Optima 3 INS is approved for installation into a solid fuel burning fireplace, either a masonry fireplace (built to UBC 37 or ULC S628 standards) or an approved factory-built / zero clearance fireplace (built to UL 127 or ULC S610 standards). See pages 20 and 21 for additional information on venting.
PLANNING YOUR INSTALLATION MANUFACTURED (MOBILE) HOME INSTALLATION Freestanding Models – Optima 2 FS and Optima 3 FS In addition to the standard installation instructions, the following instructions may be required by local, state or federal building codes: • Stove must be permanently bolted to the floor. • An outside air inlet must be provided for combustion and be unrestricted while unit is in use. Use a galvanized or stainless steel pipe for the duct (the outside air inlet on the stove is 2" diameter).
INSTALLATION REMOVING APPLIANCE FROM PALLET 1. After removing the packaging from the stove, lift the hopper lid, and remove all pre-packaged items that were shipped in the hopper. Next, open the stove door and remove all pre-packaged items. 2. Using a socket or open end wrench (7/16" for freestanding units and 3/8" for the insert), remove the pallet bolts which secure the unit to the pallet (located on each side of back corners and at the front under ash pan). See following pictures.
INSTALLATION INSTALLING SURROUND ASSEMBLY - Optima 3 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. There is also a trim assembly that frames the surround assembly to give it an attractive finished appearance. Put the surround assembly together according to the following instructions. 1. Remove panels from package. 2.
INSTALLATION Optima 3 INS (Only) – Install damper rod knob as explained on page 11. Damper Adjustment It is very important to preset your damper prior to burning your pellet stove. Damper - Air Control Handle – Freestanding Units Damper is factory set to a gap as specified below. Follow Damper Adjustment Guidelines on page 26. Left Surround Panel For less air, slide damper knob to the right (or) for more air, slide knob to the left.
INSTALLATION THERMOSTAT INSTALLATION: NOTE: Always Disconnect Power Before Performing The Thermostat Installation. A 24 volt wall thermostat and 20 feet of 18-gage thermostat wire is included in your stoves accessory package. It is recommended that the thermostat and thermostat wire be installed by an authorized Lennox Hearth Products dealer. Installation Steps: 1. Unplug stove power cord from the wall outlet. 2. Locate the thermostat terminal block (see illustrations below). 3.
INSTALLTION VENTING REQUIREMENTS 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. Selecting a Location (Freestanding Models)- Review the appliance clearance requirements before installing the venting system (see page 7).
INSTALLTION VENT TERMINATION 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. Vent surfaces can get hot enough to cause burns if touched. Adults should supervise children when they are in the area of a hot stove. Non-combustible shielding or guards may be required.
INSTALLATION DETERMINING SIZE OF PIPE TO INSTALL To determine what diameter pipe to use in an installation (3” or 4”), first find the “equivalent pipe length” using the following guidelines, then plot this figure and the altitude on the chart. Fill out the installation chart, and calculate your total equivalent pipe length. After you have the total equivalent pipe length, use the Pipe Selection Chart below to determine if your installation requires 3” or 4” exhaust pipe.
INSTALLATION INSTALLING YOUR FREESTANDING PELLET STOVE Standard Horizontal Vent Installation 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 accommodate 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.
INSTALLATION Standard Horizontal Installation Configurations Optima 3 FS Corner Through the Wall 3” (75 mm) Minimum clearance between wall and pipe. If you vent to the furthest wall, the vent pipe must maintain a 3” clearance parallel to the other wall. Optima 2 FS Corner Through the Wall 3” (75 mm) Minimum clearance between wall and pipe. If you vent to the furthest wall, the vent pipe must maintain a 3” clearance parallel to the other wall.
INSTALLATION Standard Vertical Installation Configurations Models: Optima 2 FS and Optima 3 FS These freestanding models may be connected to an existing flue or by installing listed type “PL” vent pipe. If a liner is run all the way to the top of the existing chimney, the existing flue should be sealed with a steel plate. Start a vertical run with a Tee at the back of the stove. Other options are illustrated below.

Failure to do so may result in the transfer of soot into the room by way of the room air blower.
INSTALLATION INSTALLING OPTIMA 3 INS (CONTINUED) IMPORTANT- Make sure the chimney and firebox are clean and free of soot and ashes before installation begins. Failure to do so may result in the transfer of soot into the room by way of the room air blower. Do not block opening at front of insert (below door). Full Chimney Reline (Recommended for ALL chimney installations) Horizontal Vent (Direct Vent) IN CANADA – Installing as a Horizontal Vent is not allowed. The fireplace chimney must be fully lined.
CARE AND OPERATION CONTROL BOARD OPERATION Stove On / Off Button – This button will turn your stove on or off while in Manual or Automatic mode (see page 25 for details). The green on / off light at the top of control board will indicate the on / off status. Heat Output Button – The heat output button has three selection settings, Low, Medium and High. Pressing the button will scroll the red indicator lights from Low to High. The button controls the pellet feed and combustion airflow simultaneously.
CARE AND OPERATION Note: The control board is equipped with an internal memory which will recall the last setting and mode the stove was in prior to loss of power. Because we individually check each stove prior to packaging, one of the two scenarios will appear when you first plug in your stove. 1). The Green LED at the top of the control board will illuminate and the blowers will be running. This is a standard cool down mode and will last no longer than five minutes.
CARE AND OPERATION Combustion Voltage Trim Steps: 1. Push button “twice” for access voltage calibration mode. 2. Identify the current calibration setting indicated by one YELLOW LED bar. 3. Push the “HEAT” control button to adjust setting UP. Each push raises the YELLOW LED bar & increases voltage 5%. 4. Push the “BLOWER” control button to adjust setting DOWN. Each push lowers YELLOW LED bar decreasing voltage 5%. 5. Push the calibration button once to lock in selected results.
CARE AND OPERATION MANUAL OPERATION Pressing the stove on / off button initiates the start-up cycle. The green on / off light, near the top of the control board, will light up to indicate the “on” status. The fan speeds and pellet feeds are fixed during this time to provide appropriate ignition. The Fast-Fire igniter system will light the pellets feeding to the UltraGrate, after about 3 minutes. The start-up cycle is in effect for approximately 2 minutes after flame is detected in the UltraGrate.
CARE AND OPERATION DAMPER OPERATION (All models) The damper is a plate that helps control the amount of airflow supplied for combustion. With the damper pushed all the way in the airflow is at its minimum. As the damper is pulled out, more air is allowed to flow. It will be necessary to monitor the appearance of the flame during the first 4-8 bags of pellets.
CARE AND OPERATION FUEL 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 passages in the grate. Even P.F.I. approved pellet fuel may tend to clinker.
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 variables). Unplug and Ensure Stove is Cold Before Performing Any Maintenance Work. Include routine maintenance with annual maintenance.
ROUTINE MAINTENANCE 3. Release both ash pan latches and pull forward. Models Optima 2 FS and Optima 3 FS 4. Remove the ash pan. Place ashes into a noncombustible container. When finished, close the glass door and slide the ash pan back into the stove and close the ash pan door. Reinstall ash pan cover panel. * (Minimum Frequency of 2 days – 2 weeks) HEAT EXCHANGER TUBES (All Models) Only Clean Heat Exchanger Tubes When Stove is Cool.
ROUTINE MAINTENANCE Pull Scraper Rod out & in several times Mirror Feed Tube Scraper Rod pulled out a. Using a long soft bristled brush (i.e. artists brush), extend it deep into the feed chute and sweep away any pellet fines (on right side). b. Canned compressed air can also be used to remove pellet debris from the photoeye filter (use only canned compressed air such as what can be commonly purchased at a computer or office supply store and some drug stores).
ROUTINE MAINTENANCE Clean Photoeye Lens Clean-Out Tee Clean PhotoEye Lens Remove cover, then remove ash Remove Filter and Wipe Clean * (Minimum Frequency of 1-2 months) Filter ASH CLEAN-OUT PORTS Make sure stove is cold. Ash clean-out ports must be cleaned as part of routine maintenance. Accessing Clean-out Ports Optima 3 Series (Firebrick panels must be removed to access): IMPORTANT: Clean-out cover plates must be installed when operating unit.
ROUTINE MAINTENANCE 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.
ROUTINE MAINTENANCE SMALL AREA PAINT TOUCH-UP The stove body is painted with a quality high-temperature stove paint. Use only model TSPK-B Stove Paint, Catalog # 70K99. Do not touch-up your stove with any other paint.

TROUBLESHOOTING Qualified Technicians Only Unplug Appliance Before Performing Any Troubleshooting or Maintenance PROBLEM 1. Fire burns with a lazy orange flame. Pellets build up in the grate and there is excessive glass soot that is difficult to remove (Ash and soot are a product of combustion with any wood products, so some build-up on the glass is normal). CAUSE(S) There is insufficient combustion air.
TROUBLESHOOTING Qualified Technicians Only Unplug Appliance Before Performing Any Troubleshooting or Maintenance PROBLEM 4. Blowers will not operate when the start button is depressed. CAUSE(S) There is no power to the stove. SOLUTIONS Check that the stove is plugged in to the wall outlet. There is no power to the control board. Check to see if your circuit breaker has tripped. 5. There is soot or fly ash in the house. The window is being cleaned when the stove is operating.
TROUBLESHOOTING Qualified Technicians Only Unplug Appliance Before Performing Any Troubleshooting or Maintenance Troubleshooting Notes for Qualified Technicians only: 1.) If a ‘tri-ac’ (switching device within the controls) is blown for a particular component, it is possible for that component to run continuously. The ‘tri-ac’ can be blown due to excessive heat or a voltage spike in excess of the specified +/10% of line voltage (120v). 2.
