Gas Chimney Flue Liner - 175mm Diameter (4Z-180)

A single skin stainless steel flexible flue liner which, when installed into a masonry chimney produces a continuous and unbroken flue from appliance to outlet. This prevents flue gasses escaping though disintegrating brickwork and provides the optimum flue diameter for the appliance.

Suitable for use on appliances fired by gas (as specified by the fire manufacturer), and oils up to 28 second.

Installation Guide
1. Make sure the flue liner will go down the chimney (this can be done by pulling down a small section of the diameter liner you will be using).
2. Sweep your chimney.
3. Check you pot is in good condition, if you are NOT using a suspended cowl then remove the pot from the stack.
4. Flue liner should always be fitted from the top. Secure a piece of string (at least the same length as the flue liner to the nose cone (available separately). Now attach the nose cone onto the end of the flue liner
5. Pull the flue liner down the chimney using the string and at the same time have someone at the top of the chimney feeding the flue liner down. Once the flue liner is fitted, remove the nose cone.
6. If necessary cut the flue liner to length, and secure the liner at the top using the clamp plate. Ensure 75mm of the flue liner projects above the clamp plate so that the terminal can be located and secured.
7. Secure and seal the flue liner to a register plate, which closes off the appliance recess. Alternatively the end of the flue liner can be sealed into flue pipe or a flue gas collector or flue box.
8. Terminate the flue liner by securley fitting the terminal to the projecting section of flue liner. Apply a suitable cement as a seal and weather proof render.

Maintenance
It is recommended that chimneys serving gas and oil appliances be swept and maintained as frequently as necessary but at least once a year.
