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 OPERATING YOUR PELLET STOVE: 1. Check and fill hopper with pellets. 2. Make sure unit is plugged into a working outlet. 3. Switch the power “ON” by pushing the start-up switch once only. 4. Turn knob “B” to the 12 o’clock position. (Lower grade pellets may need a higher setting on the feed rate). NOTES: It will take longer to light if the hopper has been completely emptied or is the first fire up. The flashing green light corresponds to the auger feed rate. 5.
Routine Cleaning and Maintenance NOTE: Do not use abrasive cleaners to clean the surface or any part of the stove.
Routine Cleaning and Maintenance ASH PAN AND DOOR GASKETS (weekly) After excessive use the gasket may come loose. To repair this, glue the gasket on, using high-temperature fiberglass gasket glue available from your local ENVIRO dealer. This is important to maintain an airtight assembly. ASH PAN (weekly) Monitor the ash level every week. Remember that different pellet fuels will have different ash contents. Ash content is a good indication of fuel efficiency and quality.
Routine Cleaning and Maintenance Installation of firebox backing: • Insert center panel. • Place the side panels in the firebox and re-install the two (2) lower screws. Install top baffles. • Replace the firebrick liner. • Replace the burn pot and burn pot liner. • Close the glass door and secure. EXHAUST VENT (season) The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases.
Installation DECIDING WHERE TO LOCATE YOUR PELLET APPLIANCE: 1. Check clearances to combustibles. 2. Do not obtain combustion air from an attic, garage or any unventilated space. Combustion air may be obtained from a ventilated crawlspace. 3. Do not install the stove in a bedroom. 4.

Troubleshooting DO NOT: - Hold the start-up switch down; 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. Only qualified technicians should deal with possible internal electrical failures. - Remove any screws in the firebox without first lubricating them with penetrating oil. What to do if: 1. The stove will not start. 2.
Troubleshooting √ Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum in the fire box. Visual Check – is the blower motor turning? √ Check Vacuum levels in the exhaust channel by bypassing the Vacuum Switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic Gauge (readings must be above 0.10” W.C. on low fire). Note: If the motor fails to reach a 0.10” W.C.
Troubleshooting 5. Ignitor- Everything else in the stove operates but the ignitor will not light the pellets √ Make sure the burn pot liner is up tight and square to the ignitor tube. √ Check to see if the exhaust blower is operating. √ Check all the electrical connections on the 120°F (49°C) temperature sensor located on the exhaust channel. √ Check the connections at the ignitor socket. √ Place a jumper wire between the two (2) leads on the 120°F (49°C) temperature sensor.
Troubleshooting 7. The dial-a-fire has no effect on the fire Make sure all connections to the timer control module are secure. Perform a resistance test to the dial-a-fire potentiometer by placing the two (2) test leads from a multimeter into the leads of the potentiometer. The potentiometer should have a range of 34 KΩ to 900 KΩ (± 10%).
