Ideal Helmholtz Assembly 60kW Kit 176342

The Helmholtz Assembly 60kW Kit is a combustion-related component supplied by Ideal for its commercial boiler range. It forms part of the burner and combustion chamber arrangement on 60kW output appliances, where the Helmholtz geometry is used to damp combustion resonance and stabilise the flame pattern across the firing range.

The assembly is listed by Ideal under part number 176342 and is also referenced as 1782250. It is intended for the Evomax and Instinct Heat commercial families in their 60kW variants.

• Combustion noise or resonance from the appliance that does not clear after servicing and combustion analysis
• Unstable or erratic flame signal readings during commissioning or routine checks
• Repeated lockouts or flame failure faults on a 60kW Evomax or Instinct Heat unit
• Visible heat damage, distortion or corrosion on the assembly when the combustion chamber is opened
• Combustion readings that cannot be brought within tolerance despite correct gas inlet pressure and clean burner

• Confirm the appliance model and GC number against the compatibility list, as the 60kW kit is not shared with other output sizes
• Check the existing part number on the appliance before ordering, and note that 1782250 is also used to reference this assembly
• Inspect the burner gasket and seals while the combustion chamber is open and replace them if they show signs of deterioration
