Product Description

MI-FLUES MI-Flash No. 9 EPDM Roof Flashing 254mm to 467mm Black

Part Number: 12-9LT

Seal a large roof penetration with the MI-FLUES MI-Flash No. 9 EPDM Roof Flashing. This heavy-duty flashing suits large pipes and has a generous 630mm x 630mm base. Therefore, it provides plenty of coverage around compatible flue, chimney and ventilation pipes.

The flexible black EPDM material offers strong resistance to outdoor weather, ozone and ultraviolet light. In addition, you can shape the base to follow the profile of a suitable roof.

The No. 9 flashing suits roof pitches from 0° to 45° and has a maximum service temperature of 100°C. As a result, you must check the roof angle and expected external pipe temperature before installation.

Size information: This product is listed as covering 254mm to 467mm. However, the supplied technical specification states an external pipe range of 304mm to 457mm. Therefore, please confirm your exact pipe diameter with SNH Tradecentre before ordering.

Suitable Applications

The MI-Flash No. 9 helps create a weather-resistant seal where a large compatible pipe passes through a suitable roof. For example, it can form part of a correctly designed chimney, flue, ventilation or service-pipe installation.

However, this flashing does not replace any firestop, support or clearance required by the pipe or chimney manufacturer. Always follow the instructions supplied with the complete system.

Check the Pipe Diameter Before Ordering

Measure the external diameter of the pipe before choosing the flashing. Do not use the internal flue diameter because insulated pipes can have a much larger outside measurement.

As the listed size and supplied external pipe specification differ, please contact SNH Tradecentre before ordering if your measurement falls outside 304mm to 457mm.

How to Install the MI-Flash No. 9

1. First, measure the external pipe diameter and confirm that this flashing suits it.
2. Select the marked opening that best matches the pipe size.
3. Carefully trim the EPDM cone with a suitable knife or scissors.
4. Slide the flashing over the pipe. If required, use a suitable lubricant to help it move into position.
5. Press and shape the large base so it follows the roof profile.
6. Apply the correct sealant beneath the full edge of the base.
7. Secure the base with suitable screws and weatherproof fixing caps.
8. Finally, inspect the complete edge and make sure the base forms a secure seal against the roof.

Take care when using cutting tools and working at height. A suitably competent installer should complete the work when the flashing forms part of a chimney or flue installation.

Important Installation Checks

• Measure the external pipe diameter before ordering
• Confirm the correct cutting line before trimming the cone
• Check that the roof pitch falls between 0° and 45°
• Make sure the temperature at the flashing will not exceed 100°C
• Confirm that EPDM suits the roof covering and pipe installation
• Maintain all required distances from combustible materials
• Follow the pipe, chimney and appliance manufacturer’s instructions
• Order three fixing kits if you do not already have the required sealant and fixings
