Product Description

150mm Vitreous Enamel Flue Pipe with Door – 1000mm

Model: 67-150-015

Connect your stove to a suitable chimney system while keeping the flue easy to inspect and clean. This VIT-Smooth 150mm vitreous enamel flue pipe with access door has an overall length of 1000mm and an effective installed length of 945mm.

The built-in access door gives your installer or chimney sweep a practical entry point for routine inspection and sweeping. As a result, this pipe works well where other parts of the flue route offer limited cleaning access.

Furthermore, the smooth matt-black finish complements both traditional and contemporary stoves. The pipe forms part of the VIT-Smooth single-wall connecting flue range.

Why Choose a Flue Pipe with an Access Door?

A connecting flue needs regular inspection and cleaning. However, some installations do not provide easy access through the stove or another flue component. Therefore, this pipe includes a built-in door that gives a chimney sweep direct access to the flue passage.

The door can help with:

• Routine chimney sweeping
• Inspection of soot and tar deposits
• Removal of loose combustion debris
• Checking the internal condition of the pipe
• Maintaining a clear flue route

Position the access door where it remains easy to reach after installation. In addition, make sure nearby walls, stove chambers or other components do not block the door.

Only open the access door when the appliance and flue are completely cold. Before using the stove again, check that the door sits correctly and closes securely.

Overall Length and Installed Length

Measurement	Length
Overall pipe length	1000mm
Effective installed length	945mm
Approximate joint overlap	55mm

The connecting joint uses approximately 55mm of the pipe’s overall length. Consequently, the pipe adds approximately 945mm to the completed flue route.

Use the effective installed length when planning your system. Also, allow for adaptors, bends, supports and the connection into the chimney or twin-wall flue.

Why Choose VIT-Smooth?

VIT-Smooth combines strong steel construction with a carefully finished enamel surface. The manufacturer smooths the welded areas before applying the enamel. Therefore, the finished pipe has a cleaner and more consistent appearance than many basic welded stove pipes.

The deep matt-black finish suits most UK stoves. In addition, the internal and external vitreous enamel coating helps protect the steel from heat and corrosive combustion products.

VIT-Smooth uses 1.2mm zero-carbon steel and an enamel layer of approximately 0.2mm. Together, they create a total finished thickness of approximately 1.4mm.

Suitable Applications

This 150mm vitreous enamel pipe connects a compatible heating appliance to a suitable chimney system. For example, it may connect the appliance to:

• A suitable chimney stack
• An approved flexible flue liner
• An insulated twin-wall chimney system
• Another compatible 150mm VIT-Smooth component

The pipe suits compatible gas, oil and solid-fuel appliances. However, always check the appliance manufacturer’s instructions before selecting the flue diameter and system type.

Single-wall vitreous enamel stove pipe must not pass through walls, ceilings, floors, roofs or concealed spaces. Use a suitable insulated chimney system whenever the flue passes through the building structure.

Temperature Classification

This product carries a T600 temperature classification. Therefore, it has a nominal continuous operating-temperature class of up to 600°C when installed as part of a suitable system.

The complete installation must still meet the requirements of the appliance manufacturer, the flue manufacturer and current Building Regulations.

Installation Direction

Install the pipe with the smaller male end pointing down towards the appliance. This direction helps keep condensates and combustion deposits inside the flue system.

Before fitting the pipe, check that the access door faces a safe and practical working area. The door must remain accessible for future inspection and sweeping.

Also, support the flue correctly. Do not allow the full weight of the chimney system to rest on the stove outlet or this pipe section.

Jointing and Sealing

VIT-Smooth components use friction-fit joints, so they do not require fire clay. Push each compatible component fully into the next joint and follow the manufacturer’s fitting instructions.

Where the instructions specify a sealant or jointing compound, use only a product that suits the appliance and its operating temperature. In addition, fit any required clamps or mechanical supports.

Do not assume that sealant can correct a loose, damaged or incompatible connection. Instead, replace any component that cannot form a secure joint.

Distance from Combustible Materials

Maintain at least 450mm between this 150mm single-wall flue pipe and combustible materials. This distance matches the product’s G450 classification.

Combustible materials may include:

• Timber frames and beams
• Wooden shelves and mantels
• Furniture and curtains
• Decorative wall coverings
• Materials hidden behind plasterboard

Plasterboard alone does not always make a wall non-combustible. For example, the board may cover timber studs. Therefore, confirm the full wall construction before deciding that the installation meets the required clearance.

The stove or another part of the flue system may need a larger clearance. If so, always follow the greatest stated distance.

Can You Cut This Flue Pipe?

Avoid cutting vitreous enamel pipe whenever possible. Cutting can chip the enamel and expose the steel beneath it. Consequently, the damaged area may become more vulnerable to corrosion.

Instead, use a compatible adjustable pipe or a suitable combination of standard VIT-Smooth components to reach the required height.

If the manufacturer allows an alteration and cutting proves unavoidable, protect every exposed steel edge with suitable high-temperature paint. The modification must also preserve the correct joint direction and create a secure connection.

Cleaning and Maintenance

Check the pipe, access door and joints regularly. Look for loose connections, damaged enamel, corrosion, distortion or signs of escaping combustion products.

Arrange chimney sweeping at intervals that suit the appliance, fuel and frequency of use. Solid-fuel appliances may need more frequent sweeping because soot and tar can build up inside the flue.

During maintenance:

• Allow the stove and flue to cool fully
• Open the access door carefully
• Protect the surrounding area from soot
• Clean the flue with suitable equipment
• Check the door and its seal before closing it
• Make sure the door closes firmly before lighting the appliance

Replace the pipe if the access door becomes damaged or cannot close securely.

Important Safety Information

• Use this product only as a single-wall connecting flue component.
• Do not pass it through walls, ceilings, floors, roofs or concealed spaces.
• Keep it at least 450mm from combustible materials.
• Install the smaller male end towards the appliance.
• Keep the access door available for inspection and cleaning.
• Do not open the access door while the appliance or flue is hot.
• Follow the stove and flue manufacturers’ instructions.
• Comply with current Building Regulations and relevant standards.
• Use a suitably competent installer.

The pipe measures 1000mm overall. However, the joint uses approximately 55mm. Therefore, the pipe adds approximately 945mm to the completed flue route.

What does the access door do?

The built-in door provides access for flue inspection and sweeping. It can make maintenance easier where the stove or another component does not provide a suitable cleaning point.

Where should I position the access door?

Position the door where a chimney sweep can reach and open it safely. Also, make sure walls and other flue components will not block it.

Can I open the door while the stove is running?

No. Allow the appliance and flue to cool completely before opening the access door. Afterwards, close and check the door before using the stove again.

What diameter is the pipe?

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