What it is
SIGHT GLASS, manufacturer part number 5142364, is a Potterton Commercial spare for the Sirius 2 and Sirius 3 FS range of commercial boilers. It provides the viewing point used to inspect the flame and combustion chamber during service and commissioning checks.
Signs this part needs replacing
- The glass is cracked, chipped or visibly damaged
- The viewing window is clouded, discoloured or opaque enough to obscure the flame pattern
- Soot or combustion deposits on the glass cannot be cleaned off
- Signs of leakage or staining around the sight glass seating
- The glass is loose or no longer seats correctly in its housing
Before you order
- Confirm the boiler model against the fit list above, as the Sirius 2 and Sirius 3 FS ranges are covered
- Check the existing sight glass for visible damage and confirm the fault is with the glass rather than the surrounding seal or housing
- Have the manufacturer part number 5142364 to hand when ordering
- Isolate the appliance and follow the manufacturer's service instructions before removing or refitting the sight glass
