Ideal Shutter Pack 545kW 178199

The Ideal 178199 shutter pack is a replacement air shutter assembly for Ideal commercial boilers. It is rated at 545kW and is listed against the Ideal Commercial Imax Xtra EL range. The shutter sits in the combustion air path and controls how much air reaches the burner, so its condition and setting have a direct effect on flame stability and on the combustion readings taken at commissioning and service.

• Combustion readings that will not settle within specification during commissioning or servicing
• An unstable, lifting or drifting flame pattern at the burner
• Visible distortion, corrosion or sticking in the shutter blades or their linkage
• Rattling or vibration from the air intake area when the appliance is running under load
• Repeated lockouts or flame-failure faults traced back to the air settings

• Confirm the appliance model and its rating — this pack is listed for the 545kW Imax Xtra EL.
• Check the part number on the existing component against 178199 before ordering.
• Inspect the seals and gaskets around the air intake while the appliance is open and renew any that are perished.
• Work on the combustion side of a commercial appliance should be carried out by a suitably qualified engineer.
