Product Description

150mm Adjustable One Piece Stove Offset – Vitreous Enamel

Model: 67-150-047

Create a neat and flexible connection between your stove and chimney system with the VIT-Smooth 150mm Adjustable One Piece Stove Offset. This component combines a fixed lateral offset of approximately 100mm with a lower adjustable pipe section.

The adjustable section provides up to 200mm of vertical adjustment. Therefore, it helps you align the offset with another compatible pipe or fitting while reducing the number of separate components.

Furthermore, the one-piece design creates a cleaner appearance than an offset made from several bends and short pipe sections. Its smooth matt-black finish also complements most traditional and modern stoves.

Create a Neat and Flexible Flue Offset

A stove outlet does not always sit directly below the chimney, flue liner or twin-wall connection. In this situation, the built-in 100mm offset moves the flue route sideways to help correct the alignment.

In addition, the lower telescopic section provides up to 200mm of vertical adjustment. As a result, the installer can fine-tune the connection height without adding several short pipe sections.

The component may help when:

• The stove outlet sits slightly to one side of the chimney opening
• The flue route needs a fixed 100mm sideways movement
• The connection height needs extra adjustment
• Several separate bends would create too many visible joints
• The installation needs a cleaner and less cluttered appearance

Always check the full dimensions and available space before ordering. Although the lower section adjusts vertically, the built-in lateral offset remains fixed at approximately 100mm.

How the Adjustable Section Works

The adjustable male-ended section slides inside another compatible VIT-Smooth pipe or fitting. You can then move the section to achieve the required connection height.

The pipe provides up to 200mm of adjustment. However, you must maintain enough overlap to form a safe and secure connection. Therefore, do not extend the section beyond the manufacturer’s permitted range.

Once you achieve the correct height, follow the manufacturer’s instructions for securing the joint. Also, support the complete flue route so the stove outlet does not carry its weight.

Why Choose VIT-Smooth?

VIT-Smooth offers a high-quality alternative to standard welded black stove pipe. The manufacturer carefully finishes the welded areas before applying the enamel. Consequently, the finished component has smooth joints and an even appearance.

The deep matt-black surface suits most UK stoves. Moreover, 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 with an enamel coating of approximately 0.2mm. Together, these layers create a total finished thickness of approximately 1.4mm.

Application

This 150mm adjustable vitreous enamel offset forms part of a single-wall connecting flue. It connects a compatible heating appliance to a suitable chimney system.

For example, it may form part of a connection to:

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

The component suits compatible gas, oil and solid-fuel appliances. However, always check the appliance manufacturer’s instructions before choosing 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 part of the building structure.

Temperature Classification

This component 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, current Building Regulations and all relevant standards.

Installation Direction

Install the smaller male end downwards towards the appliance. This direction helps keep condensates and combustion deposits inside the flue system.

Before fitting the offset, rotate it into the required position. Next, check that the fixed 100mm offset lines up with the rest of the flue route. You can then adjust the lower section to achieve the required connection height.

Do not allow the offset to place sideways pressure on the stove outlet. Instead, use suitable brackets and supports to carry the weight of the complete flue system.

Jointing and Sealing

VIT-Smooth components use friction-fit joints, so they do not require fire clay. Push each compatible connection together fully and maintain the required overlap.

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

A jointing compound cannot correct a loose or incompatible connection. Therefore, replace any component that cannot form a safe and secure joint.

Distance from Combustible Materials

Maintain at least 450mm between this 150mm single-wall flue component and combustible materials. This clearance 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 does not automatically make a wall non-combustible. For example, it may cover timber studs. Therefore, check the complete wall construction before confirming the clearance.

The stove or another flue component may require a greater distance. If so, always follow the largest stated clearance.

Can You Cut the Adjustable Pipe?

Avoid cutting the adjustable section whenever possible. Instead, use its built-in adjustment to achieve the required connection height.

If the manufacturer permits cutting and no suitable alternative exists, protect every exposed steel edge with high-temperature paint. This step helps reduce the risk of corrosion where cutting removes the enamel.

Any alteration must preserve the correct joint direction and provide enough overlap for a secure connection. If you are unsure, ask a competent installer or contact SNH Tradecentre before cutting the product.

Cleaning and Maintenance

An offset changes the direction of the flue route. Therefore, the complete system must provide suitable access for inspection and sweeping.

Consider adding a compatible component with an access door if the appliance or another fitting does not provide enough cleaning access.

Inspect the offset and its joints regularly. Check for:

• Loose or insecure connections
• Movement in the adjustable section
• Chipped or damaged enamel
• Corrosion or distortion
• Soot and tar deposits
• Signs of escaping combustion products

Arrange chimney sweeping at intervals that suit the appliance, fuel and frequency of use. Replace any component that becomes badly damaged, corroded, distorted or insecure.

No. This is a single-wall connecting flue component. Use a suitable insulated chimney system for walls, ceilings, floors, roofs and concealed spaces.

How far must it remain from combustible materials?

Keep the component at least 450mm from combustible materials. If another part of the installation requires a greater distance, follow the larger clearance.

Does it need fire clay?

No. VIT-Smooth components use friction-fit joints and do not require fire clay. Nevertheless, follow the manufacturer’s instructions for any approved sealant or fixing.

Can I cut the adjustable section?

Avoid cutting whenever possible. If the manufacturer allows it, protect every exposed steel edge with suitable high-temperature paint and maintain enough overlap for a secure joint.

Does this offset include a sweeping door?

No. This model does not include an access door. Therefore, make sure the complete flue system provides another suitable point for inspection and sweeping.

What is the temperature classification?

The component carries a T600 classification, which gives it a nominal continuous operating-temperature class of up to 600°C.
