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). NOTE: Unit will take longer to light if the hopper has been completely emptied or is the first fire up. 5. Wait until the fire is established, then turn “Knob B” to the desired heat output.
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 (2-3 days) 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. Refer to “Warnings and Recommendations” for disposal of ashes. DO NOT PLACE UNBURNED OR RAW PELLET FUEL IN ASH PAN. Dump the ashes into a metal container stored away from combustibles. Monitor the ash level every week. Remember that different pellet fuels will have different ash contents.
Routine Cleaning and Maintenance Installation of firebox backing: • Install the side panels in place. Insert center panel, hold the panels in place • Install the top rod by sliding it into one side panel then across into the other panel. Screw rod in place. • Re-install steel brick liner and screw in place. • Replace top baffle EXHAUST VENT (season) The products of combustion will contain small particles of flyash.
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.

C 12 in (30 cm) Above any door or window that may be opened. (9” (23 cm) if outside fresh air installed.
Installation Outside Fresh-Air Connection: A Fresh-air intake is strongly recommended for all installations. Failure to install intake air may result in improper combustion as well as the unit smoking during power failures. Outside Wall The inlet to the intake must be below and a minimum of 12” (30cm) away from the unit exhaust outlet. Outside fresh air is mandatory when installing this unit in airtight homes and mobile homes.
Installation Mobile Home Installation - Freestanding: ● Secure the heater to the floor using the two (2) holes in the pedestal. ● Ensure the unit is electrically grounded to the chassis of your home (permanently). ● Do not install in a room people sleep in. ● Outside fresh air is mandatory. Secure outside air connections directly to fresh air intake pipe and secure with three (3) screws evenly spaced.
Installation Horizontal Exhaust Through Wall Installation - Freestanding: Vent installation: install vent at clearances specified by the vent manufacturer. A chimney connector shall not pass through an attic or roof space, closet or similar concealed spaces, or a floor, or ceiling. Where passage through a wall or partition of combustible construction is desired, the installation shall conform to CAN/CSA-B365 Installation Code for Solid-Fuel-Burning Appliances and Equipment.
Installation 10. The pipe must extend at least 12” (30 cm) away from the building. If necessary, bring another length of pipe (PL type) to the outside of the home to connect to the first section. Do not forget to place high temperature silicone around the pipe that passes through the thimble. 11. Install a vertical pipe, or if all requirements for direct venting are met, install vent termination. The stainless steel cap termination manufactured by the vent manufacturer is recommended.

Installation 4. Plug the wiring harness into the control panel (see Figure 33). 5. Loosen the front hopper lid screws and center the top surround panel under the hopper lid., tighten screws. 6. Insert each side panel anchor bolt through the top panel into the corresponding side panel holes and tighten using a 7/16” wench or socket (refer to Figure 38). Surround Panel 7. Place assembled trim over the surround assembly.
Installation The Tube Scraper Rod: Put the stainless steel rod through the hole in the heat exchanger located behind the top louvers. Thread the rod into the scraper plate, which is visible from inside the firebox by removing the top baffle. Figure 40: Tube scrapper rod placement. Slider/Damper Installation: This is used to regulate the airflow through the pellet stove. 1. Remove the slider rod (short rod with knob and nuts) from their package and open the left side panel. 2.
Troubleshooting DO NOT: ● 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. The stove will not operate when hot. 3. The exhaust blower will not function normally. 4. The convection blower will not function normally. 5.
Troubleshooting ● 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 Magnehelic Gauge (readings must be above 0.10” W.C. on low fire). Note: If the motor fails to reach a 0.10” W.C. reading, then replace the Combustion Blower. ● Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational.
Troubleshooting 6. The auger motor will not function normally. ● If the Auger gear box does not turn but the motor’s armature does try to spin then the auger is jammed. – Try to break apart jam by poking at the jam through the drop tube. If this fails then empty the hopper and remove the Auger Cover **Remember to re-seal the cover after installation** ● Make sure the exhaust blower is operating. ● Check the condition of the vacuum hose (located on the left side of the stove).
Troubleshooting 8. The 200°F (93°C) high limit temperature sensor has tripped. ● Reset the sensor and determine the cause - was it convection blower or 160°F (71°C) temperature sensor failure? Bypass the 160°F (71°C) sensor. Does the convection blower come on high? If no, replace the blower. 9. The stove will not shut off. ● 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).
