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 AND OPERATE YOUR PELLET APPLIANCE 1. Check and fill hopper with pellets. 2. Switch on power by pushing the start up switch once only. 3. Turn the Dial A Fire knob 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. 4. 5. 6 CONVECTION BLOWER SPEED CONTROL Wait until the fire is established, then turn knob “B” to the desired heat output.

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-IIIi Bay pellet stove. 1. CONVECTION FAN CONTROLLER This controller is responsible for varying the speed of the convection blower. The stove does have a fan control over-ride. Should the convection blower be set on low and dial-a-fire set on high, the convection blower will bypass the fan controller and go to high.
. 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. 12. 140°F (60°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 140°F (60°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.
