Ideal Upper Baffle Commercial 170303

The Ideal Commercial upper baffle is a heat-exchanger baffle supplied under part number 170303, previously listed as 82290023. It sits in the upper flueway of the appliance, where it slows and redirects the passage of hot combustion gases so more heat is transferred to the water circuit instead of escaping up the flue. It is used across a large number of Ideal Commercial boiler variants, including the Viceroy GT range.

• Combustion readings drift from the values recorded at commissioning, with flue gas temperature rising above the expected figure.
• The appliance takes longer to reach temperature or struggles to hold it under load.
• Visible distortion, burning, cracking or heavy soot deposits on the baffle when the flueway is inspected.
• Debris or fragments of baffle material found in the flueway or collecting on the heat exchanger surfaces.
• Rattle or movement from the baffle in its location, indicating it is no longer seated correctly.

• Confirm the appliance model and serial number against the compatibility list, as several Viceroy GT variants use different baffle arrangements.
• Check the existing baffle against the previous number 82290023 to confirm the correct item is being replaced.
• Inspect the flueway and any associated seals or gaskets while access is open, and replace them if they are disturbed or degraded.
