The Mi-Pellet Ø 80 Seal is specifically designed for use in low-temperature pellet biomass installations (T200), providing an essential joint seal in P1 pressure scenarios (200 pa). Constructed with zero carbon steel and featuring a vitreous enamel coating in a sleek matt black finish, the Mi-Pellet pipe is suitable for gas, oil, and solid fuel appliances with temperatures up to 600°C. However, when equipped with this seal, it can achieve a P1 pressure rating up to a working temperature of 200°C.

Note that the Mi-Pellet should not be used for high-temperature (T600) applications or pass through ceilings and combustible walls.

• Ensure the Mi-Pellet system is installed in the correct orientation, with the smaller diameter facing downwards to efficiently manage condensate formation. • Strictly use the seal for low-temperature (T200) applications – it is unsuitable for high-temperature (T600) operations or installations that pass through ceilings or combustible walls. • During installations requiring pipe modifications, any exposed steel must be treated with high-temperature paint to prevent premature rusting. • Follow manufacturer guidelines carefully to guarantee that the seal performs optimally while maintaining safety standards. • Regular inspection and professional maintenance are recommended to verify that all components of your flue system are in secure working condition.

The Mi-Pellet Ø 80 Seal is used to ensure secure joints in low-temperature pellet biomass installations, specifically where P1 pressure (200 pascals) is required.

Yes, the Mi-Pellet Ø 80 Seal is suitable for use with gas, oil, and solid fuel appliances operating at temperatures up to 600°C.

No, the Mi-Pellet Ø 80 Seal is designed for low-temperature (T200) applications and should not be used in high-temperature (T600) situations.

When installing, ensure that the Mi-Pellet pipe is oriented with the smaller diameter pointing downward to keep condensates within the flue system.

No, Mi-Pellet pipes should not be used to pass through ceilings or walls made of combustible materials such as wood or plasterboards.

For chimneys serving solid fuel appliances, it is recommended that they be swept and maintained at least once a year, but more frequently if necessary.

If Mi-Pellet pipes need to be cut, ensure that any exposed steel is covered with high-temperature paint to prevent rusting over time.
