The Mi-Pellet 250mm Pipe - Ø 80 is crafted meticulously for connecting your appliance to your Flue Liner, Chimney Stack, or Twin Wall Flue System. Constructed from zero carbon steel and adorned with a matte black vitreous enamel coating, this single-skin pipe can handle temperatures up to 600°C. Ideal for gas, oil, and solid fuel appliances, it's a dependable element in any flue system setup.

Remember, it's designed for use only within visible sections and should not pass through combustible walls or ceilings. Its friction-fit design means no sealing is required under high temperatures, and for pellet installations with positive pressure, seals must be added. Ensure no piece of the pipe is less than 375mm from combustible materials and always install the smaller diameter downwards to keep condensates inside the flue.

Regular maintenance and chimney sweeping are crucial, particularly for solid fuel systems.

• Install the Mi-Pellet pipe with the smaller diameter segment pointing downwards to ensure that condensates remain safely within the flue. • Ensure that every segment maintains a minimum clearance of 375mm from any combustible material. • Use the friction-fit design to your advantage: most installations do not require additional sealing. However, for pellet installations with positive pressure, apply seals at each joint. • Avoid routing the pipe through combustible walls or ceilings and keep it within the intended visible section. • Always wear the appropriate personal protective equipment (PPE) during installation and ensure that all installation guidelines and safety protocols are followed. • Schedule regular maintenance and chimney sweeping, especially for installations using solid fuel appliances. • If any pipe section is cut, immediately cover exposed steel with high-temperature paint to prevent rusting.

Yes, the Mi-Pellet pipe is suitable for gas, oil, and solid fuel appliances, handling temperatures up to 600°C.

When installing the Mi-Pellet pipe, the smaller diameter should always be pointing downward to ensure condensates remain within the flue system.

No, the Mi-Pellet pipe should not be used to pass through ceilings or combustible walls. It's designed only as a connecting pipe.

For T600 high temperature installations, sealing is not required due to the friction fit of the joints. However, for pellet installations with positive pressure (P1 applications), seals must be placed on every joint.

Regular inspections and chimney sweeping are essential, especially for solid fuel appliances. Install access doors at directional changes for ease of maintenance.

After cutting, any exposed steel should be covered with high-temperature paint to prevent rusting over time.

Appropriate personal protective equipment (PPE) should be worn at all times during installation to ensure safety.
