IMPORTANT SAFETY DATA To prevent the possibility of a fire, ensure that the appliance is properly installed by adhering to the installation instructions. An ENVIROFIRE dealer will be happy to assist you in obtaining information with regards to your local building codes and installation restrictions. The stove’s exhaust system works with negative combustion chamber pressure and a slightly positive chimney pressure, it is very important to ensure that the exhaust system be sealed and airtight.
PELLET QUALITY IS IMPORTANT, PLEASE READ THE FOLLOWING PAGE Your pellet stove has been designed to burn wood pellets only. Since there are many manufacturers of wood pellets it is important to select pellets that are free of dirt or any impurities. The Pellet Fuel Industries (P.F.I.) has established standards for wood pellet manufactures. We recommend the use of pellets that meet or exceed these standards. Ask your dealer for a recommended pellet type.
WARNINGS AND RECOMMENDATIONS A. Do not abuse the glass by striking or slamming the door shut. B. Do not attempt to operate the stove with broken glass. C. Do not attempt to open the door and clean the glass while the unit is in operation. To clean the glass, use a soft cotton cloth and mild window cleaner, gas or wood stove glass cleaner or take a damp paper towel and dip into the fly ash, this is a very mild abrasive and will not damage the glass. D.
HOW TO START AND OPERATE YOUR PELLET APPLIANCE 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. 5. 6.
SLIDER/DAMPER INSTALLATION INSTRUCTIONS This is used to regulate the airflow through the pellet stove. A Qualified Service Technician or Installer should set the Slider Damper. The Slider Damper is pre set from the factory. The slider damper will be set and held in place with a 5/16” hex head screw. This screw will be tightened in the middle of the slot located in the slider damper plate. The slider damper is located behind the left side panel.
AREAS FOR ROUTINE INSPECTION The following should be inspected periodically to ensure that the appliance is operating at its optimum and giving you excellent heat value: 2 3 DAYS/WEEKLY Burn Pot and Liner Ash Pan Inside Firebox Behind Firebox Liners Burn Pot and Liner Door Glass Heat exchanger tubes Ash pan and Door gaskets SEASON or 2 TONS OF FUEL Exhaust Vent Fresh air Intake Tube Blower Mechanisms Heat exchanger tubes Latch Mechanism of ash pan Door Latch All Hinges Post Season Clean-up TOOLS REQUIRED
have different ash contents. Ash content is a good indication of fuel efficiency and quality. Refer to “Warnings and Recommendations” for disposal of ashes. BLOWER MECHANISMS ( # 2 SEE PAGE 10) Unplug the stove then open the right/left side panels to access the two blowers. Only the convection blower motor (on the right side of the stove) will require lubrication. The convection motor has two lubrication holes on it. Use two drops of SAE 20, light oil to lubricate every six months.
Once you are finished using the pellet appliance for the season, unplug the stove for added electrical protection. It is very important that the stove be cleaned and serviced as stated above. (See Section Areas of Routine Inspection) 5 4 2 3 1 ELECTRICAL COMPONENT FUNCTIONS The following is a list of electrical components and their functions on the ENVIROFIRE EF-IVi pellet stove. 1. CONVECTION FAN CONTROLLER This controller is responsible for varying the speed of the convection blower.
8 7 9 5 10 14 6. EXHAUST/COMBUSTION BLOWER This variable speed fan (mounted on the left side of the stove) is responsible for drawing the outside fresh air into the combustion chamber for burning. The hot air then continues to be drawn over the heat exchanger tubes and into the exhaust channel. It is then pushed out through the exhaust system. A motor speed controller tied in with the Dial-A-Fire controls the speed of the blower. 7.
. 160°F (71°C) TEMPERATURE SENSOR When this sensor (located on the left side firewall) reaches 160°F (71°C), the convection blower will go to high, bypassing the fan controller and removing excess heat from the unit. 13. 120°F (49°C) N/O TEMPERATURE SENSOR (SHUT-DOWN SENSOR) This sensor (mounted on the exhaust blower housing) has two functions: Should the fire go out, this sensor will shut the stove off when the exhaust temperature drops below 120°F (49°C).
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. You can vent the stove through an exterior wall behind the unit or connect it to an existing masonry or metal chimney (must be lined if the chimney is over 6” in diameter, or over 28 sq. inches cross sectional area).
REMOVING YOUR NEW STOVE FROM IT’S PALLET To remove your new stove from its pallet, open the left and right side panels. There are two wood screws that are holding the bottom of the stove to the pallet. Remove the screws. Close the side panels. See PAGE 18 how to install the pedestal.

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.
The stove will not operate when hot - 2. The exhaust motor will not function normally - 3. Open the left side panel, check all connections against the wiring diagram. Thoroughly check for broken wires or connections. If all the connections are verified and the exhaust blower does not function at all, tap lightly on the exhaust blower’s motor end cap, this may loosen a tight motor. Apply 115 V directly to the exhaust blower. If the motor does not run, replace the blower.
6. The auger motor will not function normally - - 7. Make sure the exhaust blower is operating. Make sure the dial-a-fire is turned on. Unplug the stove and open the side and back panels. Check all the connections to the auger motor, auger dial-a-fire, vacuum sensor, 200°F (93°C) temperature sensor and the timing control module against the wiring diagram in this manual. Check the condition of the vacuum hose (located on the left side of the stove).
8. The stove will not shut down - 9. Check the connections to the 120°F (49°C) exhaust temperature sensor, start-up switch and the start-up timer against the wiring diagram. Check the 120°F (49°C) temperature sensor by removing one of the brown wires from the sensor. The unit should shut down right away as long as the start button was not pressed within 15 minutes of this test. If the stove shuts down within 15 minutes, replace the 120°F (49°C) sensor.
