Increasing Adaptor 100 Rigid to 125mm Flex

A metal connector which connects the flexible chimney liner (one diameter size bigger - IE. 5 inch (125mm)) to single wall pipe at the base of the stack.

APPLICATION
Connects 125mm (5 inch) Flue Liner to 100mm (4 inch) Black Pipe / Vitreous Enamel / 1mm Stainless / Single Wall flue at the bottom of the chimney stack.
HETAS recommend that if you are burning wood then you should increase the size of the flue liner by 25mm from the appliances spigot size.
This is due to the amount of condensates that can be produced from burning unseasoned wood.

CONSTRUCTION
Made from 316 grade stainless steel, it has integral drain hole to let the condensates flow back into the flue.

INSTALLATION
1.Connect the bottom of the Flue Liner to the adapters twin wall section, using self tapping screws and seal with either Fire Cement or High Temperature Silicone Sealant.
You can now connect the Adapter using Fire Cement or High Temperature Silicone Sealant to either your appliance (if the appliance is a solid fuel appliance then you must have a least 600mm of flue pipe before this connection) or Black Pipe / Vitreous Enamel / Single Wall Stove Pipe. If the gap is large between the Adapter and the pipe you can seal using a combination of Fire Cement / Silicone and Fire Rope.

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

INSTALLATION - CHECK LIST
1.Make sure the 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. 

INSTALLATION
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.
