FAQs

The primary purpose is to connect a rigid single wall flue system to a flexible MI-FLEX flue liner, ensuring a smooth transition and an increased flue size of 25mm.

Yes, it is suitable for wood with less than 20% moisture, smokeless coal, gas, and oil, accommodating temperatures up to 600°C.

Yes, according to Building Regulations Document J, the flexible flue liner must be fully enclosed within a masonry chimney, and not enclosed in non-masonry materials like timber or plasterboard.

For a gas-tight seal, it is advisable to use fire cement, ceramic rope, or high-temperature sealant to secure the bottom fixing into the connecting flue below and the flexible liner above.

The chimney should be designed for easy sweeping and maintenance. It is recommended to sweep solid fuel appliances at least twice a year and inspect the system annually.

No, chemical cleaners or mild steel tools should not be used to sweep stainless steel chimneys. Engage a HETAS registered sweep for solid fuel applications.

Provisions must be made to ensure the bottom fixing is securely fastened inside the masonry chimney and all connecting points are gas-tight, without any flexible flue liner exposed.
