The part
Fit a new 3-bar PRV on Ideal Vogue Gen2 32 when water dribbles constantly from the outside discharge pipe.
Isolate safely
Drain below the PRV, unscrew the old valve and fit new PTFE tape (10 turns clockwise).
Fit and commission
On Ideal Vogue Gen2 32 the PRV sits on the hydraulic block — torque to 25 Nm to avoid cracking the plastic manifold.
Recommission checklist
Refill the Ideal Vogue Gen2 32 to 1.2 bar cold. Bleed high-point radiators and the internal AAV.
Run a full flue-gas analysis after 15 minutes. Log the reading against the OEM commissioning envelope in the Benchmark book.
