3.Check you pot is in good condition, if you are NOT using a suspended cowl then remove the pot from the stack.

Flue Liner should always be fitted from the top.
Make sure the arrows are pointing upwards (gas flow).
Secure a piece of string (at least the same length as the Flue Liner to the Nose Cone (order separately).
Now attach the Nose Cone onto the end of the Flue Liner, again making sure the arrows on the Flue Liner are pointing away from the Nose Cone in a upward direction so when the liner is installed the arrows will be pointing to the top of the chimney
Pull the 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.

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