Product Overview
The Glowworm Boiler Flue Duct Top Assembly (Part Number: 0020020716) is a component of the combustion and flue system used in selected Glowworm Flexicom HX boilers.

Correct installation and condition of this component are important for maintaining the integrity of the flue gas pathway and supporting safe boiler operation.
ℹ️ Product Condition Options:
This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished flue components should be professionally inspected to confirm their condition, structural integrity and suitability for installation.
Technical Insight & Common Failure Symptoms
The flue duct top assembly forms part of the boiler's internal combustion gas discharge arrangement. It helps maintain the intended route for combustion products as they pass through the appliance's flue system.
Damage, deterioration, corrosion or incorrectly fitted connections may compromise the integrity of the flue duct arrangement and require professional inspection.
Possible symptoms or conditions that may indicate a flue duct or associated component problem include:
-
Visible cracks, corrosion or deterioration affecting the flue duct assembly.
-
Damage to the upper flue duct section.
-
Loose or incorrectly fitted flue duct connections.
-
Signs of deterioration around adjoining flue components.
-
Evidence of combustion gas leakage identified during professional testing.
-
Flue system integrity issues identified during servicing.
-
Abnormal combustion or flue-related faults requiring further investigation.
These conditions do not necessarily confirm a faulty flue duct top assembly, as similar issues may result from damaged seals, incorrectly fitted components or other parts of the combustion and flue system. A qualified engineer should establish the cause before replacing any component.
Safety Advice
Boiler flue duct assemblies are safety-critical components within the combustion and flue system. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.
Always isolate the appliance and allow it to cool before carrying out any work. Follow the manufacturer's installation and servicing instructions, ensuring that the correct component and any required seals or fixings are installed. Appropriate flue integrity, combustion and operational safety checks must be completed before returning the boiler to service.
If combustion gas leakage or flue system damage is suspected, the appliance must not be operated until it has been professionally inspected and made safe.
