Ideal Case Sensing Nipple Kit Mex HE 174141

The Ideal 174141 is a case sensing nipple kit for the Mexico HE range of domestic gas boilers. The nipple forms part of the case sensing circuit, the pressure-sensing path that allows the appliance to confirm the combustion case is correctly sealed and the flue is drawing as intended. It is supplied by Ideal as a kit rather than a single loose fitting.

• The boiler locks out or fails to fire, with the case sensing or pressure circuit implicated in the fault
• Repeated nuisance lockouts that clear on reset but return during normal running
• Visible corrosion, cracking or deformation of the nipple or its seating
• A leaking or blocked sensing path at the case sensing connection
• Fault finding points to a loss of pressure signal at the case sensing point rather than the switch or tubing

• Confirm the appliance GC number matches one of those listed, as the Mexico HE models use different GC references
• Have the boiler model and serial details to hand so the correct variant is identified
• Inspect the surrounding sensing tubing and connections at the same time, as faults in this circuit are often found together
