Ideal Combustion Chamber Closure 177992

The Ideal 177992 is a combustion chamber closure, listed by the manufacturer as a fumes chamber closure under reference 4035801. It forms the sealing cover over the combustion chamber on Ideal Commercial Evojet appliances, closing the chamber so that combustion products are contained and routed correctly through the heat exchanger and flue path. It is a gas-carrying component and is supplied as a direct replacement for the original closure on the Evojet range.

• Combustion readings that fall outside the expected range and cannot be corrected by adjustment
• Visible corrosion, distortion or heat damage on the closure or its sealing face
• Staining, sooting or tracking around the chamber joint suggesting combustion products are escaping
• A degraded or hardened gasket face where the closure seats against the chamber
• Cracks or mechanical damage found during a service or strip-down

• Confirm the appliance model and, where available, the serial number before ordering, as the closure is specific to the Evojet range.
• Check the existing part against reference 177992 and the alternative number 4035801 to make sure the correct closure is being replaced.
• Assess the condition of any gasket or seal that seats against the chamber and replace it where the joint has been disturbed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
