Immergas Victrix fault 29

What it means

The board detects an anomaly on the flue gas probe.

Likely causes

1. Fault on flue gas probe
2. Obstructed intake grids or exhaust terminals
3. Poor terminal placement causing recirculation
4. Obstructed or poorly positioned intake/exhaust terminals causing recirculation of flue gases into intake air
5. Poor flue termination positioning causing recirculation
6. Combustion air contaminated with chlorine, sulphur or powders
7. Chemical substances stored in the installation area
8. Installation in beauty salons, paint workshops, carpenter's shops, cleaning companies without a separated combustion air supply
9. Combustion air fed through chimneys previously used with liquid or solid fuel boilers causing soot accumulation
10. Drain trap not yet filled with condensate on first start-up
11. Sprays, solvents, chlorine-based detergents, paints, glue, ammonium compounds, powders in combustion air supply
12. Poor terminal positioning causing recirculation

Where to start

1. Access Information menu parameter d1.6 to verify flue probe temperature reading
2. Measure flue ∆P signal during flue test
3. Activate flue test (Par. 3.15)
