These appliances must be properly installed and operated in order to prevent the possibility of a house fire. Please read this entire owner's manual before installing and using your pellet stove. Failure to follow these instructions could result in property damage, bodily injury or even death.
Sincerely, All of us at Lennox Hearth Products PACKAGING LIST The assembled pellet stove model Optima 2 FS, Optima 3 FS and Optima 3 INS are packaged with an accessory package, which contains the following: One - Installation and operation instructions manual.
SELECTING A LOCATION The design of your home and where you place your stove will determine its value as a source of heat. This type of appliance depends primarily on air circulation (convection) to disperse its heat, and therefore, a cen- tral location is often best.

FLOOR PROTECTION - Optima 2 FS This appliance requires noncombustible floor protec- tion. 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 ex- tends horizontally over the floor, the protection must cover the floor under the connector and at least 2"...

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.
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.
(located on each side of the in- sert back). Side View of Optima 2 FS & Optima 3 FS (Removing Back Pallet Bolts) Remove 1 bolt on each side of stove back Note: The pallet bolt at the front of appliance is located un- der the ash pan (this will require removing the ash pan.

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 fin- ished appearance.

Make sure the wires are firmly con- nected to the thermostat. 5. Plug in the stove and you are ready to operate with your thermostat! IMPORTANT: IF THE WALL THERMOSTAT PROVIDED IS NOT USED, THE JUMPER IS REQUIRED FOR THE STOVE TO OPERATE.
Type of Pipe - This stove requires type “PL” (pellet vent pipe, sometimes referred to as “L-Vent pellet vent”), which conforms to UL standard 641. Connect the pellet vent pipe or the “tee”...
Non-combustible shielding or guards may be required. Termination Cap: The termination of the outside chim- ney of the pellet stove shall be located in accordance with the following: A. Higher than 3’ (.92m) above any forced air inlet (air conditioner, etc.) located within 10’...
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 follow- ing guidelines, then plot this figure and the altitude on the chart. Fill out the installation chart, and calculate your total equivalent pipe length.

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 chim- ney, the existing flue should be sealed with a steel plate.

INSTALLING OPTIMA 3 INS (CONTINUED) IMPORTANT- Make sure the chimney and firebox are clean and free of soot and ashes before installation begins. Fail- ure 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).
Fault Mode – The control system automatically moni- tors the flame using a photoeye. If the stove runs out of pellets the control board automatically goes into a “fault” status. The control board will initiate the shut down cycle and safely shut down the stove leaving it in the “fault”...

If your stove follows that described in number 2 above, simply press the ON / OFF button once to turn the stove off, this will initiate the cool down mode. The stove can be restarted at any time during the cool down mode by pressing the ON / OFF button once.

When first starting your pellet stove, it will be nec- essary to prime the auger tube. To prime the auger tube you need to first fill the hopper with pellets, and press the ON button on the control board.
2 minutes after flame is detected in the Ul- traGrate. A photoeye, monitors the existence of flame. After the start-up cycle your stove will be in the run mode. At this point the stove will operate in the heat output and blower settings selected.
Overheating: A high temperature disc (thermal switch) will automati- cally shut down the stove if it overheats. Allow up to 45 minutes cooling time before re-lighting. Keep enough convection air (from the room air blower) going through stove to keep it cooling properly, this will ensure long life of the stove.

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 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 mainte- nance with annual maintenance.

AIR WASH 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 burn grate.
Refill hopper. See (Pellets will not feed) this page. Allow stove to cool for 1 hour and re-light. If the stove has been operating at a medium to high burn rate and the room air blower has been turned down low then the fan should be turned up higher. If this problem persists (particularly at lower burn rates) then the high limit disc should be replaced by your authorized dealer.

10% of line voltage (120v). 2.) Many nuisance ‘faults’ can be avoided by properly ‘breaking-in’ the stove. It is strongly recommended that the stove be run on the ‘high’ setting until 4 – 8 bags of fuel have been consumed. The auger / feed system will loosen up during this period and begin to feed at a slightly faster rate which may have an impact during the ‘start-up’...
