Product Description

125mm Vitreous Enamel Flue Pipe 250mm Long – 67-125-012

The 125mm Vitreous Enamel Flue Pipe 250mm Long provides a strong and neat connection between a compatible heating appliance and an approved chimney, flue liner or twin-wall system.

This rigid VIT-Smooth pipe has an overall length of 250mm and an effective installed length of approximately 195mm. Therefore, it is ideal for short connecting sections within a compatible 125mm flue system.

The pipe uses strong 1.2mm steel with a smooth vitreous enamel coating inside and outside. As a result, it offers excellent resistance to heat, combustion gases and corrosion. Its matt-black finish also complements most traditional and modern stoves.

Why Choose VIT-Smooth?

VIT-Smooth uses carefully finished welds to create a clean appearance. In addition, the welds on compatible bends are ground down to produce a smooth surface.

The deep matt-black finish complements many wood-burning, multi-fuel, gas and oil appliances. Therefore, the visible pipe can blend neatly with the stove and fireplace.

Furthermore, the vitreous enamel covers both the inside and outside of the pipe. This coating helps protect the steel against high temperatures, combustion gases and normal corrosion.

What Is This Flue Pipe Used For?

This pipe connects a compatible appliance to an approved chimney system. For example, an installer may use it between a stove outlet and a chimney liner adaptor or twin-wall flue adaptor.

However, this product is a single-wall connecting pipe. Therefore, it must only form part of the visible connecting section within the room containing the appliance.

Suitable Appliances and Fuels

• Compatible wood-burning stoves
• Compatible multi-fuel stoves
• Suitable solid-fuel heating appliances
• Suitable oil-fired appliances
• Suitable gas appliances
• Domestic appliances with a compatible 125mm outlet

The appliance manufacturer must allow the use of a 125mm connecting flue. In addition, the complete chimney system must suit the fuel, appliance output and flue-gas temperature.

Important Installation Restrictions

Do not use this single-wall stove pipe to pass through a wall, ceiling, roof, loft or concealed area. Instead, the installer must change to a suitable insulated chimney system before reaching these areas.

The pipe requires a minimum clearance of 375mm from combustible materials under its G375 classification. These materials may include timber, furniture and some wall or ceiling finishes.

However, the complete installation must also follow the appliance instructions and current Building Regulations. If those instructions require a greater clearance, the installer must use the greater measurement.

Correct Installation Direction

The installer should fit the pipe with its smaller male end pointing downwards towards the appliance. This direction helps keep soot and condensate inside the flue system.

Before joining the sections, the installer must check that every component belongs to a compatible 125mm system. They should also follow the manufacturer’s instructions for fire cement or high-temperature joint sealant.

Can the Pipe Be Cut to Length?

A competent installer may cut the plain end when a shorter length is required. However, they must measure carefully because the section cannot be made longer again.

After cutting, the installer should remove sharp edges and protect any exposed steel with suitable high-temperature paint. Otherwise, moisture could reach the bare steel and cause corrosion.

Inspection and Cleaning

The flue system must allow safe inspection and cleaning. Therefore, the installation may require an access door, especially near bends or changes in direction.

Solid-fuel chimneys need regular sweeping to remove soot and deposits. The required frequency depends on the appliance, fuel and level of use. Therefore, follow the appliance instructions and use a competent chimney sweep.

Installation Requirements

A competent installer should design and fit the flue system. For solid-fuel appliances, use a HETAS-registered installer or notify the work to Local Authority Building Control where required.

The installer must follow the appliance instructions, flue manufacturer’s guidance and current Building Regulations. They must also check the chimney route, ventilation, clearances, termination and access for sweeping.

A carbon monoxide alarm must be installed where current regulations require one. However, an alarm does not replace correct installation, maintenance or chimney sweeping.

What diameter is this stove pipe?

This pipe has a nominal diameter of 125mm, which is equivalent to approximately 5 inches.

What is the effective installed length?

The overall pipe measures 250mm. However, the joint overlaps the next component. Therefore, its effective installed length is approximately 195mm.

Can I use it with a wood-burning stove?

Yes, it can suit compatible wood-burning and multi-fuel appliances. However, the stove must have a suitable 125mm outlet, and the complete flue system must meet current rules.

What is the maximum temperature rating?

The product has a T600 classification. Therefore, its maximum continuous operating temperature class is 600°C.

Can this pipe pass through a wall or ceiling?

No. This single-wall pipe must not pass through walls, ceilings, roofs or concealed areas. A suitable insulated chimney system must serve those parts of the installation.

The product’s G375 classification requires a minimum clearance of 375mm. However, always follow any greater clearance stated in the appliance or installation instructions.

Which way up should the pipe be installed?

The smaller male end should point downwards towards the appliance. This direction helps keep soot and condensate inside the flue system.

Can this flue pipe be cut?

A competent installer can cut the plain end if required. However, they must remove sharp edges and protect all exposed steel with suitable high-temperature paint.
