Important Installation Information: • The Mi-Pellet Increaser is designed exclusively as a connecting pipe and is not intended for passing through ceilings or combustible walls. • In positive pressure (P1) installations, ensure a seal is correctly fitted on every joint to meet safety standards. • Always install with the smaller diameter pointing downward to facilitate the proper flow of condensates within the flue system. • Regular inspections and cleaning are recommended, especially for solid fuel applications; consider installing access doors at directional changes for easier maintenance. • During installation, wear appropriate personal protective equipment (PPE) and if cutting the pipe, immediately cover any exposed steel with high-temperature paint to prevent corrosion.

The Mi-Pellet Increaser is suitable for gas, oil, and solid fuel appliances with temperatures up to 600°C.

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

Regular inspections and cleaning are essential, particularly for solid fuel applications. Install access doors at changes of direction to facilitate this.

Ensure the smaller diameter is pointing downward to keep condensates within the flue system. Maintain a distance of at least 375mm from combustible materials.

Wear appropriate PPE during installation. If the pipe is cut, cover any exposed steel with high-temperature paint to prevent rust.

No sealing is required for T600 high-temperature installations. However, seals are necessary for positive pressure (P1) installations.

When fitted with a seal, it can achieve a P1 pressure rating up to a working temperature of 200°C (T200).
