205mm pepper pot flue terminal sizing — what should I measure?
Correctly measuring the existing chimney pot opening is the most important step before ordering.
- Measure the internal diameter of the opening at the top of your existing chimney pot.
- Confirm that the opening can accommodate an approximately 205 mm outside-diameter spigot.
- If the chimney pot is tapered, irregular or weathered, measure the opening in more than one direction.
- Do not rely solely on nominal inch sizes. Clay chimney pots can vary in wall thickness, taper and actual internal dimensions.

How to install the KYL13 pepper pot
Straightforward fitting principles for installation into a suitable redundant chimney pot.
Ensure the chimney is not serving a working combustion appliance.
Measure the internal diameter and confirm that the approximately 205 mm external spigot can be accommodated.
Check that the chimney pot, flaunching, stack and surrounding masonry are secure and suitable for installation.
Position the lower section of the terminal inside the opening of the existing chimney pot.
Secure using suitable external-grade mortar and finish neatly around the junction.
Ensure the terminal openings remain unobstructed and retain suitable low-level ventilation to the redundant flue where required.
For redundant stacks, controlled ventilation is generally preferable to completely sealing the flue. A chimney serving a working combustion appliance requires a terminal appropriate to the appliance, fuel and chimney system.
General UK guidance relating to chimneys, flues and combustion appliances can be found in Approved Document J . Listed buildings and properties in conservation areas may also require chimney terminals and external alterations that are sympathetic to the character of the building.
Chimney-level work involves significant work-at-height risks and should only be undertaken using appropriate access and safety arrangements.
205mm pepper pot FAQs
Common questions about KYL13 sizing, suitability and installation.
What does the 205 mm measurement refer to?
The 205 mm measurement is the approximate outside diameter of the lower spigot. This is the section designed to insert inside the opening of the existing chimney pot.
What is the internal diameter of the KYL13?
The KYL13 has an approximately 175 mm internal base diameter and an approximately 205 mm external spigot diameter.
Is 205 mm the size of the chimney pot or the flue?
Neither. The 205 mm dimension describes the outside diameter of the lower insert spigot. Measure the internal diameter of your existing chimney pot opening to determine whether the terminal will fit.
Should I measure the inside or outside of my chimney pot?
Measure the inside diameter of the opening at the top of the existing chimney pot. This is the opening into which the approximately 205 mm external spigot is inserted.
How large is the KYL13 pepper pot?
The KYL13 has an approximately 300 mm top diameter, 205 mm external spigot diameter, 175 mm internal base diameter and an approximately 200 mm overall height.
Can this terminal be used on a working fire or wood-burning stove?
No. The KYL13 pepper pot is intended for redundant or disused flues. A working stove, open fire or other combustion appliance requires a terminal or chimney cowl suitable for the particular appliance, fuel and flue system.
Does a redundant chimney need ventilation?
In many situations it is beneficial to retain controlled ventilation through a redundant flue rather than completely sealing it. Ventilation can help disperse moisture, condensation and stale air within the chimney.
Will the pepper pot keep all rain out?
The covered profile helps reduce direct rainfall entering the chimney while retaining ventilation. It should not be regarded as creating a completely watertight seal.
What if my chimney pot opening is only slightly larger than 205 mm?
Measure carefully before ordering. The existing opening must be sufficiently large for the approximately 205 mm outside-diameter spigot to enter and for the terminal to be installed securely.
