Specifications SAFETY DEVICES: Air Bleeder Valve: Located under unit top of the unit. To remove the top follow these steps (refer to Figure 4): 1. Open hopper lid and remove the two (2) screws at the front. 2. Loosen the two (2) screws at the back of the top. 3. Remove top. 4. Replace the top by using the reverse of the method used to remove it. ��� ������� ����� Figure 3 Refer to Figure 5 and 6 for the following safety devices. See next page to remove cabinet sides.
Specifications To remove the cabinet sides, follow these steps: 1. Loosen the three (3) screws from both sides on the back of the appliance (see Figure 7). 2. Remove the ash drawer cover (see Figure 8). 3. Remove the four (4) screws, two on each side, under the ash drawer holding the cabinet sides on (see Figure 9). 4. Slide cabinet side forward and out. 5. Replace cabinet sides by using the reverse of the method used to remove them. 6. Replace the ash pan cover.
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. 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).
Installation VENT TERMINATION REQUIREMENTS: 1. Do not terminate the vent in any enclosed or semi-enclosed areas such as a carport, garage, attic, crawlspace, narrow walkway, closely fenced area, under a sundeck or porch, or any location that can build up a concentration of fumes such as stairwells, covered breezeway, etc. 2. Vent surfaces can become hot enough to cause burns if touched by children. Non-combustible shielding or guards may be required. 3. Termination must exhaust above the inlet elevation.
Installation CLEARANCES TO COMBUSTIBLES: This unit can be installed on a combustible floor due to the built in pedestal hearth pad (for example linoleum, hardwood flooring). If combustible flooring is underneath the unit 6 inches (153 mm) on either side and to the front must be protected by non-combustible material. If this unit is to be installed onto a carpeted surface, a hearth pad must be used for stability. C B A Floor Protection Figure 12 Maintain these clearances to combustibles.
Installation THERMOSTAT INSTALLED: This control board can be placed into two different modes: When the jumper J2 is not jumped then the control board is in a HI / LOW mode operation. If the control board is placed with J2 jumped (factory setting) then the control board is in a ON / OFF mode of operation. A) HI / LOW: When the jumper is placed on only one of the J2 pins, then the control board is in a HI / LOW mode of thermostat operation.

Installation HORIZONTAL THROUGH WALL INSTALLATION: The ENVIRO EF THERMO can be vented by a couple of different methods. 1. NOTE: Use only listed type “PL” or “L” pellet venting products. Failure to use listed components may cause damage or personal injury or death. 2. Choose a location for your stove that meets the requirements stated in this manual and allows installation with the least amount of interference to house framing, plumbing, wiring, etc. 3.

Installation INSIDE VERTICAL INSTALLATION: 1. Choose a stove location that is ideal. See the section Deciding Where to Locate Your Pellet Appliance. 2. Place a non-combustible hearth pad where necessary. 3. Place the unit on the hearth pad and space it in a manner so when the pellet vent is installed vertically, it will be 3” (76 mm) away from a combustible wall. 4. Locate the center of the fresh air intake pipe on the unit.
Installation OUTSIDE VERTICAL INSTALLATION: To accomplish an outside vertical installation, follow steps 1 through 9 in the Inside Vertical Installation section and then finish it by performing the following: 10. Install a tee with clean out on the outside of the house. 11. Install PL vent upward from the tee. Make sure that you install support brackets to keep the vent straight and secure. 12. Secure the flashing as you go through the roof. 13.
Installation MOBILE HOME INSTALLATION: •Secure the heater to the floor using the two bolt holes supplied in the pedestal. CAUTION: THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED. •Ensure the unit is electrically grounded to the chassis of your home (permanently). •Do not install in a room where people sleep. •Outside fresh air is mandatory when installing into airtight homes or manufactured homes.
Troubleshooting DO NOT: Hold the ON / OFF BUTTON; 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. Do not remove any screws in the firebox without first lubricating them with penetrating oil. WHAT TO DO IF: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. The stove will not start.
Troubleshooting «Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational. «Exhaust Temperature Sensor failure – Bypass sensor located on Exhaust Channel. If stove now operates properly, the unit may require cleaning or a new sensor. Contact your local dealer for service. «The unit may require cleaning. Contact your local dealer for service.
Troubleshooting 8. 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). «If the unit is in the HI/LOW mode the unit will not shut off but will go to an idle setting (LOW). Press the ON/OFF button to turn the unit off. «Disconnect one of the brown wires from the exhaust temperature sensor. If the unit continues to operate, contact your local dealer for service. 9.
