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.
PLANNING YOUR INSTALLATION FLOOR PROTECTION 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 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 Standard residential or manufactured (mobile) home installation.
INSTALLATION MANUFACTURED (MOBILE) HOME INSTALLATION Model –T300P Series 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. • Stove must be permanently electrically grounded to the steel chassis of the home.
INSTALLATION DAMPER ROD INSTALLATION 1. Locate rectangular cutout on bottom stove panel behind ash pan. Fig. A For initial setup, push the damper all the way in (when facing the front of the stove, “in” is to the left, and “out” is to the right) and slowly pull back three notches (see Fig. B). 2. Screw damper rod into threaded hole. Pulled Back 3 Notches DAMPER ADJUSTMENT The damper rod is located under the bottom plate, on the right hand side of the stove, just behind the ash pan.
INSTALLATION Model T300P Series (viewed from stove back) 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.
INSTALLATION 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 - Review the appliance clearance requirements before installing the venting system (see Clearances, page 6).
INSTALLATION 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. Chimney Height Requirements The vent termination height required is 12” minimum above the roof penetration point as illustrated below (Ref. National Standard, NFPA 7-4.1).
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 PELLET STOVE Standard Horizontal Exhaust Installation (Direct Vent) 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 INSTALLATION CONFIGURATIONS – Standard Horizontal Installations If you vent to the furthest wall, the vent pipe must maintain a 3” clearance parallel to the other wall. Note: Horizontal run of pipe requires 1/4” / 7 mm rise per foot.
INSTALLATION Installation Configurations / Standard Venting Options This appliance 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. Note: See page 11 for Vent Termination Requirements. Preferred Installation – Vertical Vent Through the Roof.
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 19 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 switch 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 The damper is a plate that helps control the amount of airflow supplied for combustion. With the damper pushed in all the way, 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 REQUIREMENTS Using the UltraGrate burn system, 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. 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.
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). ROUTINE CLEANING Note: Stove will need to be shut off and cooled enough to handle before routine cleaning is performed. Always disconnect power before doing any routine cleaning.
ROUTINE MAINTENANCE PHOTOEYE The photoeye is positioned to view the flame from the top of the auger feed tube.
