Introduction PELLET QUALITY: Pellet quality is important, please read the following: Your enviro pellet stove has been designed to burn wood pellets only. Do not use any other type of fuel, as this will void any warranties stated in this manual. The performance of your pellet stove is greatly affected by the type and quality of wood pellets being burned. As the heat output of various quality wood pellets differs, so will the performance and heat output of the pellet stove.
Introduction IMPORTANT SAFETY DATA: Please read this entire Owner’s Manual before installing or operating your ENVIRO Pellet Stove. Failure to follow these instructions may result in property damage, bodily injury or even death. Contact your local building or fire official to obtain a permit and any information on installation restrictions and inspection requirements for your area.
Introduction ASHES: Disposed ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be on a non-combustible floor on the ground, well away from all combustible materials pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispensed, they should be retained in the closed container until all cinders have been thoroughly cooled. ELECTRICAL: The use of a surge protected power bar is recommended.
Operating Instructions AUTOMATIC SAFETY FEATURES: Your pellet Stove has the following safety features: A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120°F (49°C). B. The stove has a high temperature safety switch. If the temperature on the hopper reaches 200°F (93°C), the auger will automatically stop and the stove will shut down when the exhaust temperature cools. If this happens, call your local dealer to reset the 200°F (93°C) high limit switch.
Operating Instructions STOVE CONTROLS - CIRCUIT BOARD: 1. AUGER TRIM: The Auger Trim Button is used to increase or decrease the feed rate on LOW, ONLY. Push the Auger Trim button until the number 1 and 5 lights appear on the Heat Level Indicator. This will increase the feed rate to 4 seconds ON time Auger pulse. This is done only on LOW to allow the burning of poor quality fuels. Push the button until the number 1 and 4 lights appear, this will reduce the Auger On time to 2 second.
Operating Instructions OPERATING YOUR PELLET STOVE - CIRCUIT BOARD: PRE-BURN INSTRUCTIONS: The burn pot liner holes must be clear and the liner installed properly against the ignitor tube for proper operation.

Troubleshooting This troubleshooting is for both Timer Control and Circuit Board style EF3. It will be stated if the troubleshooting relates only to one model. DO NOT: ● Hold the ON / OFF BUTTON down for circuit board model or hold the start-up switch down for timer control. This is a momentary contact switch and can be damaged if held down too long. ● Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard if handled improperly.
Troubleshooting Caution: Installation of a new start-up timer without checking the ignitor resistance may cause another failure to the new start-up timer due to a short in the ignitor. The proper resistance through the ignitor should be 30Ω to 50Ω ± 3Ω. 2. The stove will not operate when hot. General: ● Check the hopper for fuel. ● Incorrect air damper setting - Excessive air may consume the fire too quickly before the next drop of fuel, leaving completely unburned fuel in the burn pot liner.
Troubleshooting ● Check all the connections between the controller, switch, and the convection blower against the wiring diagram. ● If the convection motor will not run, apply 115 V AC to the motor directly. If the motor runs, replace the fan controller. If the motor does not run, the convection blower has failed. Replace the blower.
Troubleshooting ● To test the exhaust vacuum, place a magnehelic gauge in the sensor end of the vacuum tube. It should read 0.5” W.C. If the reading is good, replace the vacuum sensor. ● If none of the below work contact your local dealer for service. Circuit Board □ Check the fuses on the circuit board (see “Troubleshooting - Fuses”). Timer Control: ◊ Make sure the dial-a-fire is turned on. ◊ Unplug the stove and open the side and back panels.
Troubleshooting 10. The stove will not shut off. General: ● If the unit will not shut off, ensure that the thermostat (if equipped) is turned down below the room temperature (thermostat mode in the ON / OFF position). ● Disconnect one of the brown wires from the exhaust temperature sensor. If the unit continues to operate, contact your local dealer for service. Circuit Board: □ If the unit is in the HI/LOW mode the unit will not shut off but will go to an idle setting (LOW).
Troubleshooting If the stove goes out and there are no pellets in the liner, the auger is stopping. General: ● See “The auger motor will not function normally” and “The exhaust blower will not function normally.” 12. Light # 2 on Heat output bar flashing (Circuit Board Only). (The Vacuum Switch contacts have opened for more than 15 sec.) □ Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as required.
