Fit a new fan on the Vaillant Ecotec Plus 832. UK part number, isolation and torque steps.
Vaillant
Part number
The Vaillant Ecotec Plus 832 uses the fan 0020219516. Check the GC serial number sticker inside the case — Vaillant revised the fan at least once during production.
Isolate
Turn off the gas at the isolation cock. Switch off 230 V at the fused spur. Drain to just below the fan: on the Vaillant Ecotec Plus 832, the drain-off is on the return pipe.
Fit
Unclip the fan. Transfer the O-rings if OEM includes new ones — always fit the new seals supplied. Torque any brass unions to 25 Nm. Refill to 1.2 bar, bleed and fire for a wet check.
