Ideal Flowswitch 18 Section 171160

The Ideal 171160 is a flowswitch designed for 18 section Ideal Commercial boiler installations. It monitors water movement through the appliance and signals the control circuit that flow is present, allowing the boiler to proceed through its firing sequence. It is a serviceable component within the Ideal Commercial range and is listed against the Viscount GTE and Nuway appliance families.

• The boiler runs the pump but does not move on to ignition, with no burner firing on a call for heat.
• Intermittent lockouts that clear on reset and return shortly afterwards.
• The appliance fails to register a demand even though water is circulating through the system.
• Fault codes or lockout indications relating to water flow or flow proving appear on the controls.
• The flowswitch paddle or body shows wear, debris build-up or mechanical damage on inspection.

• Confirm the appliance model and, where available, the GC number against the compatibility list before ordering.
• Check the number marked on the existing flowswitch; earlier units may carry 88024752 rather than 171160.
• Have the appliance isolated and drained as required before removal, and check the condition of any seals disturbed during the swap.
