How It Works - Field Controls SWG-3 Product Manual

HOW IT WORKS

1. When the thermostat calls for heat, the vent damper begins to open.
2. Within five seconds, the damper opens completely.
3. Two safety switches prove the damper is completely open before allowing the burner to fire.
4. When the oil appliance thermostat is satisfied, the vent damper remains open for approximately three minutes before closing.
This allows the remaining products of combustion to safely vent up the chimney.
5. The vent damper remains closed until the next call for heat, preventing drafts, improving comfort, and reducing heat loss.
