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. If you must clean the glass, use a soft cotton cloth and mild window cleaner. D. Do not use abrasive cleaners to clean the surface or any part of the stove. E. It is recommended that the unit be secured into its position in order to avoid any displacement. F.
HOW TO START YOUR PELLET APPLIANCE 1. Fill hopper with pellets. 2. Switch the power on by pushing the rocker switch to the manual position. FAN CONTROLLER 3. Turn Dial A Fire knob to the 12 o’clock position. (The lower grade pellets may need a higher setting on the feed rate.) 4. Approximately 15 minutes after the fire was lit, the green light should come on. WHEN THE GREEN LIGHT COMES ON, PUSH THE ROCKER SWITCH TO THE AUTO POSITION. Now the stove will shut off automatically if the fire goes out.
SLIDER/DAMPER INSTALLATION /OPERATIONS INSTRUCTIONS This is used to regulate the airflow through the pellet stove. INSTALLATION: 1. Remove the slider rod (short rod with knob and nuts) and the two nuts from their package and open the left side panel. This is the smaller of the two rods. Remove the knob from the knob. 2. Remove the knob and the outer nut from the rod. Push the rod through the hole in the slider.
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 Door Glass Heat exchanger tubes Ash pan and Door gaskets SEASONALLY or 2 TONS OF FUEL Exhaust Vent and Fresh Air Intake Tube Blower Mechanisms Heat exchanger tubes Latch Mechanism of ash pan Door Latch All Hinges Post Season Clean-up TOOLS REQUIRED TO CLEAN UN
DOOR GLASS (It is recommended that your dealer replace the glass if broken.) The door glass is made of 5 mm thick, high temperature PYROCERAMIC The center panel is 229 mm x 330 mm. To replace the glass, unscrew and remove the four glass retainers. Remove the glass and any broken pieces. High temperature fiberglass tape should be used around the glass. Replace the glass, center the glass assembly in the frame, then screw the glass retainers back to the frame. The use of substitute materials is prohibited.
ELECTRICAL COMPONENT FUNCTIONS The following is a list of electrical components and their functions on the ENVIROFIRE EF-IIi pellet stove. 1. CONVECTION FAN CONTROLLER This controller is responsible for varying the speed of the convection blower. The stove has a fan control-override. Should the convection blower be set on low and the Dial-A-Fire set on high, the convection blower will bypass the fan controller and go to high. This will cool the stove until control is given back to the fan controller.
10. 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, cooling the unit. 11.
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 less than 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.
