Product Description

Increasing Flue Adapter 125 Rigid To 150 Flex

Model: 20-125-MR

Increasing Flue Adapter 125mm Rigid to 150mm Flex. A metal connector which connects the flexible chimney liner (one diameter size bigger – ie. 6 inch (150mm)) to single wall pipe at the base of the stack.

Application

Increasing Flue Adapter 125mm Rigid to 150mm Flex connects 150mm (6 inch) flue liner to 125mm (5 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 Check List

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).

Sweep your chimney. 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.

Maintenance

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