Troubleshooting - Enviro Mini 2 Operator's Manual

DO NOT:
● 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 from the firebox without penetrating oil lubrication.
WHAT TO DO IF:
1. The stove will not start.
2. E2 on LED Display.
3. E3 on LED Display.
4. E4 on LED Display.
5. The Exhaust Blower will not function normally.
6. The Auger is not feeding pellets.
7. The Convection Blower will not function normally.
8. The Igniter not working.
9. Control settings (Heat Level) has no effect on the fire.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or installers.
1. The stove will not start.
• Make sure the stove is plugged in and the wall outlet is supplying 115-120V AC power.
• If the Control Board has been is set to Thermostat mode, turn the thermostat up to call for heat.
Check the LED display for error codes. - If Display reads E2,E3, or E4 use Troubleshoot sections.
•
• Check the fuses on the circuit board.
• If the unit still does not start, contact your local service dealer for service.
2. E2 on LED Display (The Vacuum Switch contacts have opened for more than 1:00 min)
• Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as
required. Blow out Vacuum Hose with compressed air.
• Blocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum Hose
from the Vacuum Switch and blow into the hose to remove blockage.
• Blocked exhaust / venting system - Have stove and venting cleaned and inspected.
• Air Damper is closed or set to low - open damper slightly.
• Severe negative pressure in area where unit is installed - Check the operation by opening a window, does this
solve the problem? If it does, install fresh air intake to unit or room. Venting system may require vertical section
to move termination into a low pressure zone.
• Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before
replacing the Vacuum Switch.
• Damage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
• Combustion Blower failure - If the Combustion Blower is not turning fast enough to generate the proper vacuum
in the Exhaust Channel. Visually Check if the blower motor is turning, check the Exhaust Blower voltage across
the blower wires (>=115V on #5 setting and >= 82V on #1 setting). – Replace the Circuit Board if the Voltage
reading is less than 82 V. with a line voltage >115 V AC.
• Check Vacuum levels in the exhaust channel by bypassing the vacuum switch, then remove the Vacuum hose
from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a
Magnehelic Gauge. (readings must be above .09" WC on low fire).
• If the motor fails to reach a 0.09" WC readings, then replace the Combustion Blower
To reset Circuit Board after a trouble code - press Power button.
