Understanding Pack 706

- Pot Hanging Cowl with Mesh: Ensures that the flue liner is properly supported while maintaining the aesthetics of your chimney.

Key Features and Their Benefits
Versatility and Compliance
One of the standout features of Pack 706 is its compatibility with MI-FLEX 316 and 904 flexible flue liners. This dual compatibility ensures that whether you are upgrading your current system or installing a new one, the kit is up to the task. It complies with the rigorous demands of Building Regulations Document J, offering peace of mind regarding safety and efficiency.
Multi-Fuel Application
The kit’s ability to handle various types of fuel sources, such as wood (with less than 20% moisture), smokeless coal, gas, and oil, makes it an ideal solution for a wide range of applications. This flexibility means you won’t need to worry about whether your current heating system is compatible; Pack 706 has you covered.
Durability and Reliability
Manufactured from 316L stainless steel, Pack 706 promises durability in even the most demanding environments. This material resists corrosion and withstands high temperatures, which are crucial properties for any component that will be exposed to the harsh conditions of a chimney system.
The Installation Process
Pre-Installation Checks
Before beginning the installation, verify that your chimney structure is in compliance with current building codes. It is essential to inspect the chimney for any signs of wear or damage, and to confirm that the installation kit is the correct size and specification for your flue liner system.
Step-by-Step Installation
1. Prepare Your Work Area: Ensure that all safety measures are in place and that you have access to the necessary tools.
2. Install the Pot Hanging Cowl with Mesh: Secure the cowl in the designated space, making sure it is firmly attached to support the weight of the flue liner.
3. Attach the Nose Cone: Fit the nose cone to create a smooth, efficient transition from the liner to the chimney pot.
4. Use the Increasing Adaptor: Connect the adaptor to your Black Pipe or Single Wall Flue, ensuring a tight and secure fit.
5. Position the Chimney Notice Plate: Place the notice plate where it can be easily seen. This aids any future maintenance or inspection work.
Post-Installation and Maintenance
Once installed, regular maintenance is key to keeping your chimney system safe and efficient. It is recommended to have your chimney inspected at least once a year, with more frequent cleaning if you are using solid fuels. This not only ensures compliance with safety standards but also prolongs the life of the system.
Exploring Optional Accessories
While Pack 706 is a complete kit, National Flues offers a range of optional accessories to further enhance your installation. These accessories can include additional supports, specialised adaptors, or custom finishes that cater to specific installation scenarios. If your project demands extra features or you wish to personalise your installation, it's worth exploring these additional options.
