Ideal Baffle Short Right 6/7 Section 174694

The Ideal 174694 is a short right-hand baffle produced for 6 and 7 section Ideal Commercial boilers. It is listed under the Caradon part numbering system and carries the alternative number 1780216.

Baffles sit inside the flueways of the heat exchanger, where they slow the passage of hot flue gases and deflect them across the cast iron surfaces. That turbulence and dwell time raises heat transfer into the water circuit, so a baffle that has corroded, distorted or dropped out of position shows up as reduced efficiency and higher flue temperatures rather than an obvious breakdown.

• Flue gas temperature noticeably higher than the commissioning readings, with efficiency dropping off
• Overheating, kettling or repeated high limit trips on the appliance
• Soot, scale or debris collecting in the flueway around the heat exchanger
• Visible corrosion, erosion, cracking or distortion of the baffle plate
• The baffle loose, rattling or sitting out of its location in the flueway

• Confirm the appliance is a 6 or 7 section model, as the baffle is sized for that section count
• Check the data plate and serial number against the compatibility list before ordering
• Cross-reference the alternative number 1780216 if you are working from older Caradon documentation
• Inspect the remaining baffles and any seals in the flueway while access is available, as they are usually disturbed at the same time
