Take complete control of your gas-fired appliance’s chimney system with the Exodraft EFC21 – a reliable, user-friendly control unit designed to ensure both efficiency and safety.
At the heart of the EFC21 is a simple one-button operation: press to start or stop your chimney fan instantly. Once activated, the fan runs at full speed to establish proper draught, and the system intelligently adjusts to a preset operating speed once ignition is achieved.
A failsafe monitoring function continuously oversees chimney pressure; if insufficient draught is detected, the gas supply is automatically shut off to prevent any risk.
The EFC21 features two intuitive LEDs – one indicating operational readiness and one signaling any faults or alarms. A convenient 3-minute post-shutdown overrun function ensures that all combustion gases are safely evacuated after the appliance is turned off.
Key Features:
- Simple Operation: Single-button control with visual LED indicators for status and alerts.
- Failsafe Monitoring: Integrated pressure sensor ensures the chimney draught is sufficient before ignition and during operation.
- Safety First: Automatic gas shut-off in case of draught failure.
- After-run Function: Optional 3-minute fan overrun after shutdown for maximum safety.
- Universal Compatibility: Works with all Exodraft gas-fired chimney fans.
- Compact Design: Streamlined, durable casing (85 x 126 x 32 mm) blends easily into any installation environment.
