Enviro EF-119 Operating Instructions, The Reasons Why The Unit Overheated, Special Notes

Operating Instructions

AUTOMATIC SAFETY FEATURES:

Your pellet Stove has the following safety features:

A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120°F (49°C).

B. The stove has a high temperature safety switch. If the temperature on the hopper reaches 200°F (93°C), the auger will automatically stop and the stove will shut down when the exhaust temperature cools. If this happens, call your local dealer to reset the 200°F (93°C) high limit switch. ALSO FIND

THE REASONS WHY THE UNIT OVERHEATED.

C. The unit has a convection fan control over-ride. This function causes the convection fan to reach its full speed when the temperature at the back of the firebox reaches 160°F (71°C). This is a normal safety feature of your unit. To compensate for the fan cycling action that may occur, turn up the blower control proportionately to the heat output.

D. If the power goes out, the unit will stop running. When the power comes back on, the stove will not restart unless the exhaust temperature is still above 120°F (49 °C).

SLIDER/DAMPER SETTING:

This is used to regulate the airflow through the pellet stove.

A Qualified Service Technician or Installer should mark the slider rod in the current settings.

SPECIAL NOTES:

Pellet quality is a major factor in how the Pellet stove will operate. If the pellets have a high moisture content or ash content the fire will be less efficient and has a higher possibility of the fire building up and creating clinkers (hard ash build-up).

If the fire should happen to go out and the Dial-A-Fire has been set on the lowest setting, the Slider Damper should be pushed in slightly, decreasing the air in the firebox or the Dial-A-Fire can be turned up slightly.

If, after long periods of burning, the fire builds up and overflows the burn pot or there is a build up of clinkers, this would be a sign that the pellet quality is poor, this requires more primary air, the slider damper must be pulled out to compensate. Pulling the slider damper out gives the fire more air.

The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of the fire.

•A tall, lazy flame with dark orange tips, requires more air – Open slider (pull out) slightly.

•A short, brisk flame, like a blowtorch, has too much air – Close slider (push in) slightly.

•If the flame is in the middle of these two characteristics with a bright yellow/orange, active flame with no black tips then the air is set for proper operation.

Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge can be used to set the slider for best combustion. The best settings are a reading of 0.12 to 0.13 inches of water column (30 Pa) on the high fire setting. Some fuels may require higher or lower settings. The reading can be taken from the 1⁄8” (3 mm) hole located on the front of the unit below the door and behind the magnetic ash lip.
