What it is
The Biasi BI1563500 is a gas restrictor intended for natural gas operation. It fits within the gas train of the listed Biasi Advance, Inovia and Basica COND appliance families, where it sets and limits the gas flow reaching the burner. Correct fitment of the restrictor is essential to achieving the appliance's specified gas rate and combustion readings.
Signs this part needs replacing
- Gas rate at the meter falls outside the appliance's specified range and cannot be corrected by adjustment
- Combustion analyser readings drift from the expected CO2 or CO figures for the appliance
- Unstable flame, flame lift or poor ignition that persists after servicing the gas train
- Visible damage, blockage or distortion at the restrictor orifice
- Whistling or unusual noise from the gas valve or burner area under demand
Before you order
- Confirm the appliance model and GC number against the fitment list above
- Check whether the appliance is set for natural gas or LPG, as the restrictor differs by gas type
- Compare the marking on the existing restrictor with the part number before removal
- Verify the correct restrictor position and orientation in the manufacturer's service documentation
