Ideal Central Baffle Short 6-7 Section 174692

The Ideal 174692 is a short central baffle for Ideal Commercial appliances built with 6-7 section heat exchangers. It sits in the heat exchanger flueways, slowing and redirecting combustion gases so more heat passes into the water circuit instead of going straight up the flue. Because it lives in the hottest part of the appliance, it is subject to continuous heat cycling and flue gas attack, and will distort, corrode or burn away over its service life.

• Heat output drops or the appliance takes noticeably longer to reach temperature
• Overheat thermostat trips or the appliance locks out on high limit
• Combustion readings drift outside the expected range at the flue test point
• Rattling, rumbling or uneven noise from the heat exchanger
• Distortion, heavy corrosion or missing baffle sections found during a strip-down

• Confirm the appliance model and that the heat exchanger is a 6-7 section casting before ordering
• Check the baffle position and length against the short variant — section count determines which baffle is correct
• Cross-reference the alternative number 1780200 against older service documentation
