1. CONVECTION BLOWER SPEED CONTROL (KNOB A): By adjusting the knob you will vary the

rate of airflow into the room by varying the speed of the convection blower. When you first start the stove, it should be placed in the “OFF” position in order to heat the unit as quickly as possible. Once the room has come up to temperature, the control may be set to a comfortable level.

2. AUGER LIGHT: For the EF3/4/5 the flashing green light corresponds to the auger feed rate. For the EF2 it indicates unit is hot – switch unit to auto

3. START-UP SWITCH: For the EF3/4/5 it switches the power “ON” by pushing the start-up switch once only. For the EF2 manually start the unit – then switch to auto when green light comes on. This allows the unit to shut off when the re goes out.

4. Dial-a-fire HEAT OUTPUT (KNOB B): This knob controls the amount of heat output. The dial has a scale with the blue zone representing the coolest setting of the stove, and the red zone representing the hottest setting. The scale on knob “B” represents a range, not exact at times or fuel quantities. Wood pellets of differing quality may affect the performance of the stove. If the stove has trouble operating at either end of its range, turn the heat output knob turn heat output knob up or down slightly. SPECIAL NOTES: The scale on the Dial-a-fire knob represents a range, not exact times.

ConTrol Board FunCTions - omega:

1. ON/OFF BUTTON: To turn on the stove, press the On/Off button. A start up sequence will begin where one of the fuel type indicator lights will turn on. This light will remain on until a proper fire is established.

Changing the heat level settings will move the heat level indictor light but will have no effect on the

feed rate until the proper fire is established.

When the stove has established a proper fire the fuel type indicator light will flash in sequence with

the fuel feed. The stove will operate on the last feed setting selected.

To turn off the stove, press the On/Off button and the stove will start its shut down sequence. You will

not be able to alter any of the stoves operations during this shut down sequence. When the stove is cold it will turn off. This may take 10 to 15 minutes.

2. FUEL TYPE BUTTON: Used to switch between fuel type modes; Pellet (for all qualities of wood pellets) and Multifuel (for all fuels including wood pellets). When set on Multifuel it will run at a reduced High Feed Rate with wood pellets.

Switching to the Multi-fuel setting. The Omega must be completely off to switch between the pellet feed and the multi-fuel feed. If you

have been running the Omega and want to change from one fuel type to another you must turn the stove off and allow it to go through a full shut down cycle. Then you can change the fuel type by pressing the fuel type button. The Omega will switch between the pellet setting and the multi-fuel setting. An indicator light will show which setting is chosen, green for pellet and yellow for multi-fuel.

Trimming the multi-fuel settings.

You can increase or reduce the feed rates in

the multi-fuel setting. Follow the procedures in Stove ControlS; Control Board FunCtionS - omega item number 7.

Why change feed rates?

There are a wide variety of fuels available today.

We give the operator the ability to trim the feed rates to allow the Omega to burn a wide variety of fuel types and sizes. In general the volume of fuel being fed through the auger is determined by the average size of the fuel. The smaller the average size the more fuel will be fed. Good wood pellets tend to be larger in size, averaging from ½” to 1 ¾” long. Lower quality pellets or alternate fuels like corn have smaller particle sizes ranging from ¼” to ½”.

Burning pellets in the alternate feed

setting.

You can reduce the feed rate for pellets, lower

than the lowest trimmed rate setting if desired. To do this, you can burn wood pellets on the multi-fuel feed setting. This will reduce the pellet feed by approximately 12%. You can then use the feed trim button to further alter the feed rate. This process allows the feed rate to be

Figure 8: Omega Circuit Board Control Panel.

Stove Controls

altered by approximately 30% from its highest to its lowest setting giving the consumer tremendous control over their Omega.

Burning alternate fuels in the pellet setting. It is not recommended to burn alternate fuels, or pellets with small particle sizes, on the pellet setting.

Doing this may cause the Omega to run dirty. If you notice your glass getting black more quickly or the exhaust coming from the end of the flue pipe being dirty, then we recommend trimming the feed rate down or switching to the alternate fuel setting. This will reduce the feed rate and increase the air to fuel ratio. This will allow the Omega to run more efficiently and the stove will stay cleaner longer.

3. THERMOSTAT SWITCH: The thermostat switch allows the consumer to operate the stove in 3 different control modes known as the “Tri-Mode Operating System”; AUTO/OFF or HIGH/LOW (when using a Thermostat or Timer) or MANUAL.

You can switch between the 3 settings while the stove is running. The operations are as follows: -

Manual Mode - To increase or decrease the feed rate, simply press the heat level button up or down.

There are 5 settings. A green indicator light will move to highlight the desired heat output.

Hi/Lo Mode - This mode is used when the stove is connected to a thermostat (not supplied). Turn

the stove on as per the instructions above. When the stove has established a proper fire it will transfer some of the control of the stove to the thermostat.

When the thermostat is calling for heat the stove will cycle to the last heat output setting selected i.e.

if the stove is set at #3 heat output setting the stove will operate on the 3# setting.

When the thermostat does not call for heat, the stove will cycle down to the #1 heat output setting.

It will remain at the #1 setting until the thermostat calls for heat again.

To turn off the stove, press the On/Off button and the stove will start its shut down sequence. You will

not be able to alter any of the stoves operations during this shut down sequence.

Auto / Off Mode - This mode is used when the stove is connected to a thermostat (not supplied).

The stove will operate similarly to the Hi/Lo mode with one exception. If the stove cycles to the low setting and stays there for more than 30 minutes, the stove will automatically go into a shut down sequence. Any alteration to the heat settings during the shut down sequence will have no effect on the stoves operation.

When the shut down sequence is complete the stove hands control back to the thermostat. The stove

will restart automatically if the thermostat calls for heat. Any alteration to the heat settings during the 30 minute start up sequence will have no effect on the stoves operation.

4. FUEL TYPE LIGHTS: Shows the present Fuel Type selected; Pellet is green and Multifuel is yellow. The light flashes during start-up and stops flashing when the 49°C (120°F) exhaust temperature sensor switch closes.

5. HEAT OUTPUT INDICATOR: Shows the present Heat Level output setting and the Feed Trim while it is being adjusted.

6. HEAT LEVEL ADJUSTMENT BUTTONS: When pressed, they will change the heat setting of the unit from low to high. Press the up arrow button to increase heat or the down arrow to decrease the heat.

7. FEED TRIM BUTTON: Used in conjunction with the Heat Level adjustment buttons to adjust the Feed Trim.

• The Feed Trim can only be adjusted one setting at a time. This button can also be used to “prime

the auger system”.

• If you use the auger trim button it will affect all feed rate on all settings, 1 through 5 equally.

• The auger trim button only affects the feed rate and not the combustion airflow. Therefore this will increase or decrease the air to fuel ratio.

• You can increase or decrease all feed rates by two increments or steps. Each feed rate change will increase or decrease the feed rate by approximately 5% for all settings 1 through 5.

Increasing the feed rate

a) To increase the feed rate, push the auger trim button and the up button at the same time. b) The heat indicator light will flash at the current setting (e.g. if you are set on #3, that light will

flash). c) Then push the auger trim up button again, the #4 light will flash. Then the light will return to #3. d) If you push the auger trim again, together with the up button, the #5 light will flash, then return to

#3. e) If you have your heat indicator light set on #5 and you increase the feed rate, then only the #5 light

will flash. The feed rates will increase.

Decreasing the feed rate To decrease the feed rates, follow the above procedure a to c but use the down button. If you have your heat indicator light set on #1 and decrease the feed rate, then only the #1 light will

flash. The feed rates will decrease.

the auger.

3. HEAT OUTPUT INDICATOR: Shows the present heat output setting.

4. HEAT LEVEL ADJUSTMENT: When pressed, will change the heat setting of the unit from low to high. The fan runs up and down with the heat setting.

Notes:

• The convection blower speed will vary automatically with the feed

rate.

• Due to varying fuel qualities this pellet stove may not operate on

lower Heat Level settings. If your unit goes out when on a low setting move the heat level up to a higher setting.

• The lowest and highest heat levels on this pellet stove are used

for adjusting and accommodating for different pellet sizes and the varying energy produced by the fuels. The size of the pellets will change the volume of fuel being fed.

• The unit should be run at a setting where the least amount of

cleaning of the burn pot is needed.

CirCuiT Board seT-uP - dHC 2000:

The 2000 series boards are most recognizable by the 2 fuses and no slide switch. HI / LOW OPERATION (Factory Setting): One pin is covered, as shown as ‘A’ in Figure 10. When the jumper J9 is not jumped then the control board is in a HI / LOW mode operation. If the unit has been placed in the HI / LOW mode, the unit will be taken to a low or idle setting when the thermostat is not calling for heat. When the thermostat calls for heat, the unit will go to the setting that is displayed on the control board Heat Indicator. If the heating load is not great enough when the stove is on low, the exhaust temperature switch will turn the stove off.

ON / OFF OPERATION: Both pins are covered, as shown as ‘B’ in Figure 10. If the control board is placed with J9 jumped then the control board is in a ON / OFF mode of operation. In the ON /OFF thermostat mode, when the thermostat calls for heat, the unit will go through an ignition sequence and light the stove. Once lit the unit will operate at the selected setting displayed on the control board Heat Output Indicator. Once the thermostat stops calling for heat, the unit will stop feeding pellets and begin its shut down sequence until cold then turn off.

A) HI / LOW: When the jumper is placed on only one of the J9 pins, then the control board is in a HI / LOW mode of thermostat operation (factory setting).

1. Install the Low Voltage Thermostat (maximum 24V) in a location that is not to close too the unit but will effectively monitor the desired area to be heated.

B) ON / OFF: If both pins of J9 are jumped (covered), the control board is in an ON / OFF mode of thermostat operation.

Stove Operation - Timer Control

sTarT-uP sequenCe:

1. Switch the power “ON” by pushing the start-up switch once only.

2. Turn the dial-a-fire knob to the 12 o’clock position. (Lower grade pellets may need a higher setting on the feed rate). NOTE: Unit will take longer to light if the hopper has been completely emptied or is the first fire up.

3. Wait until the fire is established, then turn dial-a-fire knob to the desired heat output. The stove may not be able to stay burning in the BLUE ZONE if poor quality wood pellets are being used. Adjust the slider-damper to the appropriate setting.

4. If the stove should shut off after fifteen (15) minutes and there is still a fire in the firebox – press the start-up switch once more. If the fire went out, return to step 2 and re-light the stove.

SPECIAL NOTES:

The convection blower may cycle to high automatically depending on the setting of knobs “A” and “B”. This is a normal safety feature of the unit.

Wood pellets of differing quality may affect the performance of the stove. If the stove has trouble operating at either end of its range, turn the heat output knob forward or back slightly.

sHuT down:

To turn your stove off, simply turn the HEAT OUTPUT knob (“Knob B”) counter-clockwise until the knob clicks to the “OFF” position. This will stop the feed of pellets.

The blowers will continue to run and cool the stove. When cool enough, the stove will shut down.

DO NOT unplug unit while combustion fan is operating; this may lead to smoke escaping from the stove.

Flame Characteristics

A magnahelic pressure gauge should used when setting the slider/damper the stove.

With the slider damper set in the correct location the flame will be brisk, but not too blowing. The flame will also have a yellow to bright orange appearance. There should also be some small embers or sparks exiting the flame and burn pot liner. This is an efficient flame and is the best for proper operation.

A small blow torch like flame is a result of too much oxygen being supplied to the fire. This causes the flame to become very short and brisk with a bright yellow, almost white, flame appearance. There will also be a lot of embers or sparks exiting the flame and burn pot liner.

To fix this condition, close the slider damper until an efficient flame is achieved.

If a tall lazy orange flame with black tips is present, generally this could be a result of not enough oxygen to the fireplace or the pellet fuel being used has very high moisture content. Also a trial of smoke will leave the flame and will end up sooting the appliance.

Figure 38: Example of a good fire.

To fix this condition, open the slider damper to let more air to the fire, also make sure the pellet fuel being used is dry.

Figure 39: Example of a fire with too much

air.

Figure 40: Example of a fire with not enough

air.

Components Of A Pellet Stove

120°F (49°C) N/C Ignitor Temperature Sensor: This sensor (mounted on the exhaust channel) will

turn the ignitor OFF when the exhaust temperature reaches 120°F (49°C). This is a normally closed sensor that open when it is heated to 120°F (49°C).

160°F (71°C) Convection Fan Sensor: When this sensor mounted on the left side firewall reaches

160°F (71°C) the convection blower will go to high cooling the unit before it overheats.

200°F (93°C) Manual Reset High Limit Temperature Sensor: This sensor (located on the right

hand side of the firewall) has a red push button in the center of the sensor. This is a safety device. In the event that the convection blower fails, this sensor will detect the stove might overheat and will shut the power OFF to the auger motor.

Auger And Auger Motor: The 1 rpm auger motor is responsible for turning the auger shaft, which in

turn transports pellets to be dropped into the burn pot. The timing control module and the dial-afire control the auger motor. This can be checked using 110V AC direct power.

Auto/Manual Switch (EF2 only): This starts the stove in the manual position, when the green light

comes on push the switch to the auto position.

Control Board: This device controls the operation of the unit. This device has been designed to fully

operate the unit; the control board can change the amount of fuel that delivered to the burn pot as well as room air blower (convection blower) functions. This device is also responsible for turning the unit ON and OFF. This control board can be operated manually or a wall thermostat can be installed on this unit as well.

Convection Blower: This blower mounted on the right hand side of the stove draws room air from the

back of the stove and passes the air through the heat exchanger tubes and back into the room. The sealed system keeps the room air separate from the combustion air. The fan controller controls this fan. This can be checked using 110V AC direct power.

Convection Fan Controller: This controller is responsible for varying the speed of the convection

blower. The stove does have a fan control override. Should the convection blower be set on low and the dial-a-fire set on high, the convection blower will by-pass the fan controller and go to high speed. This will cool the stove until control is given back to the fan controller. To eliminate the possibility of the fan cycling the fan controller and the dial-a-fire should be set proportionately to one and other. The controller can cause the fan to have low speed rumble if the output voltage is too low.

Combustion/Exhaust Blower: This fan mounted on the left hand side of the stove is responsible for

drawing outside fresh air into the combustion chamber for burning. The hot air then continues to be drawn over the heat exchanger tubes and then into the exhaust channel. It is then pushed out through the exhaust system. This can be checked using 110V AC direct power.

Dial-a-fire (Heat Output Control): This unit is responsible for controlling the timing of the auger

motor. When turned clockwise it will cause the OFF time between auger pulses to shorten, resulting in more heat output and pellet consumption. Turn the counter-clockwise and the reverse will happen. When it is turned fully counter-clockwise until it clicks the auger will stop. This can be checked using an ohm meter.

Components Of A Pellet Stove

Exhaust Temperature Sensor: This sensor is anormally open, is mounted on the exhaust blower

housing, and has two functions:

1. Should the fire go out, this sensor will shut the stove off when the exhaust temperature drops below its set point.

2. When the auger is turned OFF via the dial-a-fire, the exhaust temperature will drop, when the exhaust temperature drops below set point the sensor will shut the stove OFF.

Green Light: For EF 3 & 4 this light will flash in conjunction with the pulses of the auger. For the EF2

the light signals you to put the stove into the auto position.

Ignitor: A heating element used to ignite the pelletized fuel when the start-up switch is activated; the

ignitor is activated by the start-up timer. Air passes through the ignitor tube, which the air becomes super heated drying the fuel and then igniting the fuel through convection.

Phase Controller (EF4): The EF 4 has a phase controller which is responsible for reducing the speed

of the combustion/exhaust blower as the dial-a-fire is turn down to a lower flame setting, this will decrease the air flow through the appliance helping the stove run more efficiently.

Start-Up Switch (EF 3 & 4): When this switch is pressed it will initiate a start-up timer including the

ignitor if installed in the unit.

Start-Up Timer (EF 3 & 4): This start-up timer bypasses the exhaust temperature sensor allowing the

stove to operate when the unit is cold. The timing cycle is initiated by pressing the start-up switch. The start-up timer is located right under the timing control module on the right hand side rear pillar. This is also responsible for turning the ignitor ON.

Timing Control Module: The timing control module is mounted above the start-up timer located on

the right rear support pillar. This module controls the switching of power to the auger. The timing

control modules switching duty is controlled by the dial-a-fire.

Vacuum Switch: This safety device (located on the

left rear support pillar) detects vacuum in the exhaust system. If the blower fails or the vent pipe becomes plugged, this switch will sense that there is no air flow through the exhaust vent and will stop the auger from feeding pellets and then finally shutting the stove OFF.
