Safety Warnings & Recommendations * This manual is designed for the technician in conjunction with the owner’s manual. * Please read this entire Technical Manual before installing or operating your Enviro Pellet Stove. Failure to follow these instructions may result in property damage, bodily injury or even death. Any unauthorized modification of the appliance or use of replacement parts not recommended by the manufacturer is prohibited.
Safety Warnings & Recommendations ELECTRICAL: The use of a surge protected power bar is recommended. The unit must be grounded. The grounded electrical cord should be connected to a standard 110-120 volts (3.6 Amps), 60 hertz electrical outlet and also must be accessible. If this power cord should become damaged, a replacement power cord must be purchased from the manufacturer or a qualified Enviro dealer.
Installation Rating Label Location: The rating label is located on the inside of the hopper lid. Deciding Where to Locate your Pellet Appliance: 1. Do not install the stove in a bedroom or room where people sleep in. 2. Locate the stove in a large and open room that is centrally located in the house. This will optimize heat circulation. 3. Check clearances to combustibles and for the least amount of interference to house framing, plumbing, wiring, etc. 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: This Heater must have adequate air for proper combustion in the room that it is installed. 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. The inlet to the intake must be below and a minimum of 12” (30cm) away from the unit exhaust outlet.
Installation Mobile Home Installation: ● Secure the heater to the floor using the four (4) 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. CAUTION: THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL AND CEILING/ROOF MUST BE MAINTAINED.
Installation Horizontal Exhaust Through Wall Installation: 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.
Installation 7. Push the stove straight back, leaving a minimum of 4” (10 cm) clearance from the back of the stove to the wall. Seal the vent pipe to the thimble with high temperature silicone. 8. The pipe must extend at least 12” (30 cm) away from the building. If necessary, bring another length of pipe 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. 9.
Installation RECOMMENDED - Through Wall With Vertical Rise and Horizontal Termination Installation: Termination cap 90°elbow Wall framing A 45° down elbow with a rodent screen may be used in place of the termination cap (or stainless steel termination hood). Vertical section of vent pipe Wall strap Horizontal frame for thimble Clean out tee Wall thimble Figure 13: Venting horizontally with rise.
Installation Outside Vertical Installations: To accomplish an outside vertical pipe installation, follow the “Horizontal Exhaust Through Wall Installations” section and then finish it by performing the following (refer to Figure 15). 1. Install a tee with clean out on the outside of the house. 2. Install PL vent upward from the tee. Make sure that you install support brackets to keep the vent straight and secure. 3. Install ceiling thimble and secure the flashing as you go through the roof. 4.
Installation Inside Vertical Installations: 1. Place the unit on the hearth pad if a hearth pad is to be used (or on solid material if installed on a carpeted surface) and space the unit in a manner so when the pellet vent is installed vertically, it will be 3” (7.6 cm) away from a combustible wall. 2. Install the tee with clean out. 3. Install the pellet vent upward from there. When you reach the ceiling, make sure that the vent goes through the ceiling fire stop. Maintain a 3” (7.
Installation Hearth Mount Installation: Damper Removed or Fastened Open Mantel Minimum 200mm (8") from top of stove Clean-out Min 150mm (6") Fresh-air intake should com from chimney.

The stove will not start. 2. The stove will not operate when hot. 3. The exhaust blower will not function normally. 4. Light # 3 on Heat output bar flashing. 5.
Troubleshooting • • Exhaust Temperature Sensor failure. Bypass sensor located on Exhaust Blower, if stove now operates properly, the unit may require cleaning or a new sensor. Contact your local dealer for service. Check the agitator to make sure it is turning properly 3. The exhaust motor will not function normally. • Open the access panels; check all connections against the wiring diagram. • Check the Exhaust Blower voltage across the blower motor wires (>=115V on #5 setting and >= 75V on #1 setting).
Troubleshooting 8. Ignitor - the pellets will not light. NOTE: The ignitor should be bright orange in color. • Everything else in the stove operates but the ignitor will not light the pellets. • Make sure the burn pot liner is up tight and square to the ignitor tube by pulling the ignitor tube out towards the liner. • Check to see if the exhaust blower is operating. If not, contact your local dealer for service. 9. Control settings (Heat Level) has no effect on the fire.
