Ideal Fan Assembly 30 40 60 kW 176272

The Ideal fan assembly 176272 is the combustion fan fitted to Ideal commercial Evomax 2 boilers in 30 kW, 40 kW and 60 kW ratings. It pushes fresh air into the combustion chamber so the gas can burn correctly, then clears the burnt gases from the appliance once combustion is complete. The boiler's safety interlock is arranged so that gas cannot reach the main burner while the fan is not running, which makes the fan a critical part of the combustion circuit rather than a simple ventilation component.

• The boiler locks out or fails to reach ignition, with a fan or airflow fault indicated on the controls
• The fan becomes noisy in use, with rumbling, scraping or whining that points to worn bearings
• The appliance fires briefly and then shuts down because airflow cannot be proved
• Repeated overheat or flue-related lockouts that clear on reset but return on the next demand
• The impeller feels stiff, gritty or damaged when the fan is turned by hand with the power isolated

• Check the GC number on the appliance data badge against the compatibility list, as the same assembly covers 30 kW, 40 kW and 60 kW Evomax 2 models on both natural gas and LPG.
• Compare the number on the fan being removed: 1782184 and N0175-D are also used to identify this assembly.
