Ø135 · Ø160 · Ø200
Three catalogue internal diameters for straight fireclay liners.
Chimney systems
VULCO fireclay chimney liners. A system, not just a pipe.
VULCO UNIVERSAL combines a fireclay liner, insulation and an outer structural block. Catalogue sections are Ø135, Ø160 and Ø200 mm, with straight, connecting and clean-out elements.
Short answer
A fireclay chimney liner is the refractory inner passage of the system. The Volcano catalogue lists VS liners in Ø135, Ø160 and Ø200 mm, 330 mm high with a 25 mm wall, VST 90° connecting tees, VSB clean-out elements and VSJ jointing compound. Final selection depends on the appliance, fuel, temperature, condensate, height and chimney route.

VULCO UNIVERSAL
Three layers. One controlled flue-gas path.
The VULCO system in the Volcano catalogue combines a refractory fireclay liner, thermal insulation and a load-bearing outer casing. It is intended for naturally draughted appliances, with the section selected to suit the appliance and project.

Diameter is not selected from the opening alone. Appliance output, fuel, height, route, condensate and draught must be checked as one system.
VS
Straight fireclay liner
330 mm high, 25 mm wall; half-groove connection with jointing material.
VST
90° connecting tee
660 mm high; the connection matches the liner internal diameter.
VSB + VSJ
Clean-out and correct joint
The clean-out element has a 130 × 260 mm opening. VSJ jointing compound seals the half-groove between liners.

How is a chimney pipe selected?
Diameter matters, but it is not the only criterion. A poorly matched pipe can contribute to weak draught, condensation, smoke spillage and unstable appliance operation.
- appliance type: stove, boiler, fireplace or industrial furnace
- fuel and operating regime
- outlet diameter, length, height and route
- flue-gas temperature and potential condensate
- condition and geometry of the existing chimney passage
Chimney pipe, flue pipe or refractory liner?
These terms are often used interchangeably, but they do not always describe the same part of the system. We match the proposal to the actual use rather than only the search term.
- flue pipes connect a combustion appliance to the chimney
- chimney pipes form part of the vertical flue-gas passage
- refractory elements are used where thermal conditions require them
- existing chimneys should be assessed before relining or alteration
A whole-system approach
A chimney is more than a pipe. Connections, lining, insulation, combustion chamber and operating conditions all affect safety and durability.
- linking the chimney solution to the appliance and refractory lining
- assessing existing conditions before intervention
- a practical next step based on available facts

FAQ
Chimney pipe questions
Clear answers to the questions customers ask most often.
How do I determine the required chimney pipe diameter?
Diameter should not be selected only by the available opening. The appliance outlet, capacity, fuel, chimney height and route, temperature and appliance manufacturer guidance all matter.
Can the same pipe be used for wood, pellets, gas and coal?
Not necessarily. Fuels create different flue-gas temperatures, compositions and condensate levels, so the material and system design must match the actual conditions.
Can a new pipe be installed inside an existing chimney?
Relining may be possible, but it depends on the existing passage, height, route and condition. An inspection or good photo documentation is the first step.
Can I receive an initial quote from photos?
Photos and basic measurements are often enough for an initial assessment. If safe and accurate selection requires more data or a site visit, we will state that clearly.
