What Is a 250mm Vitreous Enamel Flue Pipe?

This product is a short, rigid section of single-wall connecting flue pipe. It carries combustion gases from a compatible heating appliance towards a suitable chimney or insulated flue system.

The pipe works well where space is limited. For instance, a 500mm or 1000mm pipe may make the flue route too tall. In that case, this 250mm section can help you create the required height with less cutting.

However, this pipe does not form a complete chimney system on its own. You must connect it to a suitable chimney, flue liner or insulated twin-wall system.

Overall Length and Effective Installed Length

The pipe measures 250mm from end to end. However, part of the pipe enters the next component when you assemble the joint. As a result, the pipe adds approximately 195mm to the completed flue route.

Measurement	Approximate Length
Overall component length	250mm
Joint overlap	55mm
Effective installed length	195mm

Therefore, use the 195mm effective length when you calculate the finished height of your installation. Also, allow for the socket depth of adaptors, bends and other components in the complete system.

Why Choose VIT-Smooth?

VIT-Smooth provides a high-quality alternative to basic welded black stove pipe. The production process creates neat joints and an even finish. Consequently, the pipe looks clean when fitted in a visible stove installation.

The manufacturer forms the pipe from 1.2mm zero-carbon steel. It then adds approximately 0.2mm of powder vitreous enamel. Together, these layers create a total finished thickness of approximately 1.4mm.

Furthermore, the enamel covers both the inside and outside of the pipe. The internal coating helps resist heat and corrosive combustion products. Meanwhile, the external coating provides a deep matt-black surface that matches most UK stoves.

Suitable Appliances and Flue Systems

You can use this pipe with compatible gas, oil and solid-fuel appliances. These may include wood-burning stoves, multifuel stoves and other domestic heating appliances.

However, always check the appliance instructions before ordering. The appliance manufacturer will state the required flue diameter, temperature class and installation conditions.

This component can form part of a connection between an appliance and:

• A suitable masonry chimney
• An approved flexible flue liner
• A compatible chimney adaptor
• An insulated twin-wall flue system
• Other matching 150mm VIT-Smooth components

Application

This 150mm vitreous enamel pipe is suitable for use as a visible connecting flue component. It connects a compatible appliance to an appropriate chimney or insulated flue system.

The product carries a T600 temperature classification. Therefore, its classified maximum continuous flue-gas temperature is 600°C.

Do not use single-wall vitreous enamel stove pipe to pass through walls, ceilings, floors, roofs, cupboards or concealed spaces. Instead, use a suitable tested and insulated chimney system wherever the flue passes through the building structure.

Planning the Installation

First, measure the distance between the appliance outlet and the next flue component. Next, calculate the length that each component will add after the joints overlap.

This pipe adds approximately 195mm to the assembled flue route. Therefore, do not base your calculation on its full 250mm overall length.

In addition, check that the completed route provides suitable access for inspection and sweeping. Straight pipe has no built-in access door. Consequently, you may need an access-door pipe, inspection elbow or tee elsewhere in the system.

Correct Installation Direction

Fit the pipe with the male or smaller-diameter end pointing downwards towards the appliance. The female end should face upwards towards the chimney.

This direction keeps condensates and combustion deposits inside the flue. As a result, they can travel back towards the appliance instead of leaking onto the outside of the pipe.

Finally, make sure every joint enters fully and remains properly aligned. The completed flue should not place excessive weight or sideways pressure on the appliance outlet.

Jointing and Sealing

VIT-Smooth uses a friction-fit connection system. Therefore, the joints do not normally require fire clay.

However, follow the instructions supplied with the appliance and complete flue system. If those instructions require a jointing compound, use only a suitable fire cement or high-temperature sealant approved for the application.

Do not use ordinary household sealant. It may not withstand the temperature or combustion products inside a flue.

Can You Cut This Flue Pipe?

Avoid cutting wherever possible. Cutting can chip the vitreous enamel and expose the steel beneath it. It can also remove a formed connection end.

Instead, consider using a shorter fixed pipe or a compatible adjustable component. This approach usually keeps the enamel coating and joint system intact.

If the manufacturer permits cutting and alteration is unavoidable, protect every exposed steel edge with suitable high-temperature paint. Also, make sure the altered pipe still forms a safe and secure connection.

Clearance from Combustible Materials

The product classification states a minimum distance of 450mm from combustible materials. Combustible materials can include timber, furniture, curtains and heat-sensitive building products.

In addition, do not automatically treat plasterboard as non-combustible. It may cover timber studs or form part of a combustible wall structure.

The appliance or another component may require a greater clearance. If requirements differ, always follow the greatest stated distance.

Inspection and Maintenance

Check the pipe and joints regularly. Look for movement, damaged enamel, corrosion, staining or signs of leakage.

In addition, arrange regular chimney sweeping. The correct sweeping schedule will depend on the appliance, fuel and frequency of use.

Clean the external enamel with a soft, dry or slightly damp cloth after the pipe has cooled fully. Avoid abrasive pads and harsh chemicals because they may mark the matt-black finish.

Replace the pipe if it becomes badly damaged, distorted, corroded or insecure.

Frequently Asked Questions

What diameter is this flue pipe?

The pipe has a nominal internal diameter of 150mm, which equals approximately 6 inches.

Is the pipe 250mm long after installation?

No. It measures 250mm overall. However, the joint uses approximately 55mm of that length. Therefore, the pipe adds approximately 195mm to the assembled flue route.

Why is the installed length shorter?

One end enters the next compatible pipe or fitting. This overlap creates the joint and reduces the visible installed length.

Which way up should I install the pipe?

Point the male or smaller-diameter end downwards towards the appliance. Then position the female end towards the chimney.

Can I use this pipe with a wood-burning stove?

Yes, you can use it with compatible solid-fuel appliances, including many wood-burning and multifuel stoves. However, check the appliance instructions for the correct diameter and flue classification.

Can the pipe pass through a wall or ceiling?

No. This is a single-wall connecting flue pipe. It must not pass through walls, ceilings, floors, roofs or concealed areas. Use an appropriate insulated chimney system for building penetrations.

How far must the pipe remain from combustible materials?

The declared minimum distance is 450mm. However, follow a greater distance if the appliance or another system component requires it.

Does the joint need fire clay?

No. VIT-Smooth uses friction-fit joints, so fire clay is not normally required. However, follow the appliance and flue-system instructions regarding any approved sealant or jointing compound.

What does T600 mean?

T600 means the product carries a nominal continuous operating-temperature classification of up to 600°C.

Can I cut the pipe?

Avoid cutting if possible because it can damage the enamel and expose the steel. Instead, use a suitable shorter or adjustable component. If the manufacturer permits cutting, protect every exposed edge with high-temperature paint.

Does this pipe include a sweeping door?

No. This model is a plain fixed pipe. Therefore, make sure the complete flue system includes suitable inspection and sweeping access elsewhere.

What warranty does the pipe have?

The manufacturer lists a 12-year warranty, subject to its installation, use and warranty conditions.
