What it is
The Ideal 170856 is a pilot pipe assembly for Ideal commercial gas boilers. It forms part of the pilot circuit, carrying gas to the pilot injector so the pilot flame can establish and then light the main burner through the gas valve. The pilot assembly it belongs to typically comprises a pilot bracket, injector, electrode and thermocouple, working alongside the printed circuit board to give secure, repeatable ignition.
Signs this part needs replacing
- The pilot fails to light or will not stay lit once the burner demand starts
- A weak, unstable or discoloured pilot flame that will not hold steady
- Repeated boiler lockouts or ignition faults traced to the pilot circuit
- Visible damage, corrosion, cracking or a blocked pilot pipe on inspection
- Soot or debris build-up around the pilot injector restricting gas flow
Before you order
- Check the boiler's GC number and model plate against the compatibility list before ordering
- Confirm the part number 170856 or the alternative number 1177908 matches the item being replaced
- Inspect the pilot injector, electrode and thermocouple at the same time, as these are commonly replaced together
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
