ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Any refurbished flue component must be professionally inspected to confirm its condition, structural integrity and suitability before installation.

Technical Insight & Common Failure Symptoms

The vertical flue terminal is designed for installation at the termination point of a suitable vertical concentric flue system.

The 60/100mm concentric configuration uses separate inner and outer passages for combustion gas discharge and combustion air intake.

The terminal must be correctly positioned, secured and installed in accordance with the boiler and flue manufacturer's instructions.

Possible signs that a vertical flue terminal may require inspection or replacement include:

• Visible cracks or physical damage to the terminal.

• Deterioration of the external flue components.

• Damaged or insecure flue connections.

• Incorrectly positioned or loose terminal components.

• Obstructions affecting the air intake or flue outlet.

• Damage identified during boiler or flue servicing.

• Signs of deterioration affecting the integrity of the flue termination.

These signs do not necessarily confirm that the terminal itself is defective. Flue-related problems may also result from incorrect installation, obstructions or damage elsewhere in the flue system. Professional inspection is required before replacement.

Compatibility

This part (MPN: 5118576) is identified as a Baxi Multifit 60/100mm Vertical Flue Terminal for selected Baxi concentric flue installations.

Please verify the exact boiler model, approved flue group, terminal dimensions and installation requirements against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler flue terminals are safety-critical components of the combustion and flue system. Inspection, installation and replacement must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.

Always follow the manufacturer's flue installation instructions and ensure that the terminal is correctly positioned, supported and secured. Any disturbed flue connections or seals must be checked, and all required flue integrity, combustion and operational safety checks must be completed before the boiler is returned to service.
