Ideal Boiler Chip Card Evomax Nitrogen Gas 120 176425

The Ideal 176425 is a boiler chip card supplied as a BCC kit for Ideal commercial heating appliances. It is a printed circuit board (PCB) component that forms part of the boiler's electronic control assembly, carrying the control data the appliance needs to run its sequence correctly. The part is listed against the Evomax and Instinct commercial ranges, including the Evomax 120 and Instinct Heat 120 models.

• The boiler locks out or fails to complete its ignition sequence, with the fault returning after a reset.
• Error or fault codes appear on the appliance display that point to the control board or chip card.
• The boiler runs intermittently, dropping out mid-cycle without an obvious mechanical or gas-side cause.
• No display, blank screen or unresponsive controls on the appliance fascia.
• A previously working board shows signs of heat damage, corrosion or moisture ingress around the chip card.

• Confirm the appliance model and GC number against the compatibility table above before ordering, as the same part number is not used across every Ideal commercial range.
• Check the existing chip card and board for the part number printed on the component, and compare it with 176425.
• Note the alternative number 1781902 when cross-referencing stock or older paperwork.
• Work on the boiler's control assembly should be carried out by a competent engineer, with the appliance isolated electrically before the board is disturbed.
