Introduction

The Traditions line is a metal firebox housed within a cast body.

There are three-baked porcelain enamel styles. They are Mojave Sand, Hunter Green, and Ebony Black. A fourth model is painted black cast.

There are two motors for air movement, the combustion motor and convection motor.

The upper Hob, or top of the appliance, directs convection air down to the hearth.

These all come with legs and are fully automatic, standard equipped with thermostat and wire.

There are ash slides and an ash drawer. A damper control handle is located behind the ash drawer on the right side facing the appliance.

The Profile 20 & 30 product lines, as well as the Cascade model, are sheet metal in construction. The Profile 20 & 30 models contain a separate motor for combustion and convection air movement. The Cascade has one motor that drives two fans on a single shaft. All models are top feed, negative pressure combustion units. The Cascade has legs, while the Profile 20 & 30 freestanding models are on a pedestal. Each model contains ash slides and an ash drawer. The Profile 20 & 30 models are fully automatic and come standard with a thermostat and wire.

The Auger motor is rated at 120 V.A.C. 60 Hz. Its speed rating is 1 RPM with 87 in-Lbs. Starting torque is 118 in-Lbs minimum with a 126 in-Lb average. The minimum breakdown torque is 200 in-Lbs. with a continuous duty cycle. The coil is impedance protected. The motor has an Ohms resistance rating of 17.99 Ohms and Amperage of .55 maximum.

All pellet appliances use the patented Ultra Grate. This design allows maximum air delivery to the fuel load for combustion through a series of stainless steel bars at the bottom of the grate. Secondary air holes located on the front and rear face direct flame vertical. A single large hole is provided for the Igniter airflow during start-up.

NOTE: The Cascade model does not have an igniter yet the Large hole is present in the grate. This permits common part usage in pellet products.

Feed System / Operation

FUEL DELIVERY RATES: The power ON/OFF Time is determined by the selected feed setting on the control board. The auger motor is supplied shots of electricity and the auger shaft moves fuel toward the grate for combustion.

* Lbs per hour shown is based on factory settings. Calibrations will vary rates.

** BTUs vary with pellet type *** The burn time will vary with size and type of fuel being used.

All fuel differs in make up because of the raw stock available to each fuel manufacturer. Soft woods and hardwoods not only have various burn characteristics, but they feed through the stoves with slightly different traits. Feed trim adjustments are incorporated on all control boards to compensate for these traits in fuel types.

The chart below depicts the average feed rate for base fuel of each model at each predetermined setting of the control board. The operator when different fuels do not fall within these ratings can supplement Trim. Remember, as a rule of thumb, Long fuel feed slowly while short fuel feeds fast and heavy fuel feeds fast while light fuel feeds slowly.

Pellet Fuel

PELLET FUEL INSTITUTE Standards for Pellet Fuel: Heat Content: 8200 BTU/Lb. Min. Bulk Density: 40 Lb. per Cubic Ft. Min. Moisture Content: 8% Max. Ash Content: 1% Max. (PREMIUM)

3% Max. (STANDARD) Size: 0.23 to 0.35 in diameter

1.5 inches long Maximum Fines: .5% Max. (Passed through 1/8th in screen)

The Cascade, Profile series, and Traditions Pellet Stoves can burn most pellets that meet the PFI Premium or Standard Fuel criteria. Ash fusion, or clinkering, is also an important fuel parameter. This is not addressed in the PFI Standards. Clinkering is a low-grade glass making process whereby the silica in the ash softens at temperature and then solidifies on cooling as a clinker and blocks off the primary combustion air holes in the grate. The fire will then burn very rich and soot up the firebox and window rapidly. A clinker can be easily removed using the grate scraper tool. Lift the clinker up and out of the grate and deposit it in the ash pan when cleaning the stove. The clinkering characteristics of the fuel depend on the silica content of the non-combustible ash and the quantities of the trace elements of sodium and potassium (salts), which significantly reduce the melting point of the silica. A fuel that meets the PFI Standard may possibly have poor clinkering characteristics, which would make it an unsuitable fuel for this stove. Care must be taken in recommending suitable fuels to customers, or advising customers of how and when to remove the clinkers.

All stove models are equipped with the Ultra Grate system and may burn Standard grade fuel with up to 3% ash content. Although the Ultra Grate allows the burning of such lower grade/high ash fuels; such as paper, cardboard, corn and other agricultural fuels, their use should be avoided. LENNOX Hearth Products recommends Premium Grade.

(The use of low grade fuel will void the stove warranty)

Each model appliance is equipped with a damper control to adjust for ash build-up during long-term operation. This is a temporary fix. Proper air to fuel ratio is electronically controlled by the software within the control panel. Still adjustments, both electronically and manually may be required to dial in combustion air. Refer to Owners manual for proper damper settings. Remember to close ash slides during appliance operation as well. A leak in this area severely depletes combustion air from being matched with fuel delivery. Heavy ash deposit on the glass is a tell-tale sign of improper air to fuel ratio.

Power Supply

The LENNOX Hearth Products pellet appliance line will not operate using natural draft, or without a source of power for the blower and fuel feed systems. These appliances are rated for 120 V.A.C. at 60 Hz. An 8 Ft. UL approved power cord is provided with each product. Extension cords should be avoided. The appliance amperage draw will differ between models. Having the appliance on its own house circuit insures proper power delivery at all times power is available. Testing has proven the use of supplemental power to be acceptable. All models are generator and inverter capable. The amount of wattage required will depend on the amperage draw of each model. When using an inverter, the reserve battery size will determine the length of power supply available. When using a generator, a secondary power draw attached to the generator will stabilize the power output to the appliance and prevent unforeseen problems.

In the Profile and Traditions models when power is applied to the stove, for example, when it is plugged into the wall socket, or after a power outage, the control board will start a 3-second timer. During this time, no visual indication that the stove has been powered up will show!

This allows the power source to stabilize.

The Cascade will properly respond to power when the Heat control is positioned to High or Low. If it does not, check for a bad fuse or plug connection.

If the Cascade fans start when unit is plugged in, check for a bad low limit switch.

The Profile and Traditions control boards contain a memory. These appliances will resume operation in whatever state they were in before power was removed.

The simplified SSAC control board that is used with the Cascade model only contains a three position Slide Switch and a fuel trim pot. There is an 8 AMP fast blow fuse located on the rear of the circuit board. With the slide switch in the OFF position the stove will not operate. The LOW position sets the auger duty cycle and blower speed to low. On HIGH both systems advance to high. The trim adjustment compensates for fuel differences. Factory set ON time is 1.9 sec. The trim range is 1.6 to 4.5 sec. Factory OFF time for low is fixed at 4.2 sec and for high its fixed at 1.15 sec. The LED is energized whenever the auger motor circuit has power.

Power will remain on with a hot stove when the slide switch is set to OFF for 25 min (+/- 5 min)

Pictured with Quick Disconnect

The Profile 20 & 30 series, along with the Traditions models, house a thermally protected Class B insulated combustion fan motor. It connects to the wiring harness via a two pin white Molex plug connection. The wire leads are 18 ga. as well as the as the green motor ground wire.

A 12 blade self-cleaning radial impeller draws air from upstream (the firebox) creating negative firebox pressure. Down stream, out the exhaust, the flue system is pressurized by the displaced air (exhaust). Typical performance of free air is rated at 95 CFM at 66 watts. The Ohms range is 9-14 (+/- 4 Ohms).

Motor lubrication not required.

The Cascade model houses a FASCO blower assembly, which is made up of one 115 VAC, 60 Hz, 2.10 AMP, and 1400-200 RPM, Class B thermally protected motor. For combustion, the fan operates at 1680 RPM on low with 90CFM free air and at 2300 RPM on high with 109 CFM. The combustion fan housing, attached by 5 nuts, contains an 11-blade self-cleaning radial fan blade. When removal is required, the blower assembly access is from the rear of appliance. Disconnect the Molex plug; remove the 5 nuts on the combustion fan housing, and the 4 nutsmounting the convection fan housing.

The blower assembly is then

dropped out the bottom of the appliance. Some panel removal may be required for ease of access. No motor lubrication is required for this assembly.

The squirrel cage collects house hold dust deposits, dust bunnies, and care should be given to perform routine maintenance in this area. As the room air passes through the convection jacket and the heat exchanger, it cools the firebox by displacing the heated air into the room. Restricted air ways will cause harmonic noise, uneven air flow and could lead to high temperature shutdown conditions detected by High Limit switch. Motor lubrication is not required for this sealed fan motor.

The Profile 20 & 30 series, and the Traditions model, house a thermally protected Class B insulated convection fan motor. It connects to the wiring harness via a two pin white Molex plug connection. The wire leads are 18 Ga. as well as the as the green motor ground wire.

A plastic squirrel cage, attached to the motor shaft by a compression ring, draws room air into the fan housing in the rear of the appliance chassis.

Any exhaust leak will be drawn toward this fan intake.

The Cascade convection fan, part of the blower kit assembly, has a plastic squirrel cage impeller. It draws ambient air from the room into the convection jacket through the heat exchanger. This cools the firebox and provides convection heat to the room. Exhaust leaks from the flue system can be drawn into this fan. Smells and/or ash within the room are reason for flue seal inspection.

Question & Answers

WHAT ARE THE REASONS FOR FAULT DETECTED SHUTDOWN? If the start sequence ends without a flame being detected If Flame Detect is lost for 45 seconds continuous during start up/ Flame Detect mode If the flame is lost during the demand mode for 5 minutes continuous

RESULTS No Flame Detected = Power LED flashes 10 flashes per second Same as the Normal Shutdown previously described EXCEPT

3941 Control Board will shut off at 24 minutes 15 seconds after Start-up sequence with no flame detected.

WHAT INITATES A NORMAL SHUTDOWN? Power is switched off Thermostat indicates no need for heat

RESULTS Combustion Fan goes to mid range voltage for 15 minutes than turns OFF Convection Fan goes to mid range voltage to cool down

One minute after shut down sequence is initiated 15 minutes after shutdown sequence is initiated

All circuits will be turned OFF

Combustion Fan Operation extends to 5 minutes 15 seconds past Flame Detect before allowing panel setting to take control. Convection Fan Operation extends to 2 minutes past Flame Detect before allowing panel setting to take control. At 2 minutes past Flame Detect Fuel Feed drops to 20% rate for 4 minutes 15 seconds before allowing panel setting to take control. NOTE: The first minute after Flame Detect, NO

If a Flame is detected near the end of the Start-up Sequence, the 14 minutes 15 seconds sequence is extended to allow flame settling and ember bed to build.

WHAT ELECTRICALY TAKES PLACE AFTER A DELAYED IGNITION START-UP?

Question & Answers

DEMAND Mode State: If the thermostat is closed when power is restored there is a need for the unit to

produce heat. If flame is present the unit will enter the Demand Mode and run the loads at

panel settings. If the flame is not present the unit will initiate the Start-up Sequence.

If the thermostat is open when the power is restored there is no need for the unit to produce heat.

The unit will enter the shutdown sequence to prevent the possibility of any smoldering pellets from producing smoke that will possibly escape the firebox into the living space.

If the control board is in shutdown when power is lost the control board will initiate the shutdown sequence when power to the control board is restored.

SHUT DOWN Mode State

START-UP Mode State

If the thermostat does indicate a need for heat when power is restored to the control board and if a flame is detected the control board will enter the demand mode of operation. If a flame is not detected the control board will initiate the start-up mode of operation. If the thermostat does not indicate a need for heat when power is restored to the control board the shutdown sequence will be initiated.

Recovery from power loss situation is dependent on the state the stove was in when power was lost.

Maintenance Requirements

Ash Slides: Profile 20 and 30 freestanding models have ash slides that close with the closing of the appliances door. The Profile 30 insert contains NO ASH SLIDES. The Cascade and Traditions ash slides require the operator to ensure closure. If during appliance burn operation, an ash slide is open or loose seal, combustion air is lost and poor performance can be expected. Test the tightness of seal by placing a finger on the closed slide and press down. If there is any sponginess, the ash slide guides need to be tightened. Access to the guides is through the ash drawer compartment. Tighten the lock nuts on the guide studs (4 each)

Ash Drawers: Each model has an ash drawer. The Profile 30 insert is inside the firebox under the grate. Both the Profile 20 and 30 freestanding models have high capacity ash drawers. These models can withstand long burn usage before needing the ash drawer to be emptied. The Cascade and Tradition models, as well as the Profile 30 insert, need attention to ash build up in the ash drawer below the grate. Heavy ash accumulation here will reduce combustion air availability to the grate. Care must be given when empting ash drawers. Hot embers may be present and ash will escape into the room if exposed to air currents from the convection blower while handling the drawer.

Ash Trap Areas: Ash trap area is defined as any location ash will collect in volume and cause air flow or heat transfer problems. In the Profile 30 there are two access panels, one on either side of the grate that should be checked during routine maintenance. (Shown in the top picture to the left.) Heat exchange tubes have cleaning rods that should be operated, pulled up and down, daily. When ash is allowed to collect on the tubes, it insulates the tubes and reduces heat transfer. (Traditions tubes shown to left, handle inside firebox) Heavy ash build-up around the tubes will restrict the cleaning rods movement and could affect proper closure of the hopper lid.


23

Maintenance Requirements

Gaskets: Door gasket seals are common leak areas. A paper seal test should be performed periodically to ensure proper door seal. Remember any excessive leak in the combustion chamber, firebox, takes away from the proper air to fuel ratio. Gaskets are held in place with RTV. When replacing a gasket, use the proper replacement size and clean area of old RTV to ensure a good seat on the new gasket. Gaskets should last, with proper care, two to three seasons.

Ash Removal: Ash is the residue of pellet combustion. The term soot is often misused to describe ash. This dust collects in the exhaust air flow chambers of the appliance. If left unattended, it restricts air flow. In the firebox, ash builds to the sides of the grate. By opening the ash slides, the majority of it will drop into the ash drawer. REMEMBER to close the slides fully when stove is operating in the all models. Excessive ash build-up in the firebox will affect the air wash performance. Always ensure there are no hot embers when dumping ash drawer. Never use a paper bag to deposit ash into.

Flue vent systems should be cleaned at least once a burn season. This may become more frequent depending on fuel and appliance use. All vent pipeswithin the home shall be sealed air tight to prevent ash leakage. The flue vent system on all LENNOX Hearth Products is under positive pressure when the appliance is operating. Leaks in the flue vent system contribute to ash being found throughout the home but the main cause for this is the use of a regular shop vacuum. The filter system of such equipment is not able to handle the collection and containment of pellet ash. Photo-eye Slot: Fines may build up in front of the photo-eye slot in the feed tube. Clean this area with a small bottle brush or toothbrush periodically. The failure of fuel feed during operational modes could be the result of a blinded photo-eye.
