Ideal Burner Assembly Evo HE 173752

The Ideal 173752 is a burner assembly supplied as a burner kit for the Evo HE family of domestic gas boilers. It carries the gas and air mixture to the burner head, where combustion takes place inside the heat exchanger. The assembly is a serviceable item, so it is replaced as a complete unit rather than rebuilt on site.

• The boiler locks out repeatedly or fails to establish a stable flame on start-up.
• The flame burns yellow or lazy instead of a crisp blue, or lifts away from the burner head.
• Soot deposits, blackening or heat discolouration around the burner and combustion chamber.
• Visible corrosion, cracking, distortion or blocked ports on the burner surface.
• Combustion readings drift outside the expected range and cannot be corrected by servicing alone.

• Check the GC number and model plate on the appliance against the compatibility list before ordering, as the Evo HE range uses several burner variants.
• Confirm the alternative number 1179606 if you are working from an older parts reference.
• Inspect the burner gasket and seal during strip-down and replace them at the same time if they are disturbed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
