Flue Kit for Shed or Garden House

Many wood-burning stoves come with the choice of attaching the flue pipe to either a top or rear flue exit. From the stove, you can lead the chimney directly outside, run it upwards first and then outside, or take the chimney all the way through the house.

For the adaptor you have the following options:

Single to twin wall adaptor (also increasing adaptors)

This adaptor can be installed in two ways:

1. Direct connection – push the adaptor into the stove opening so it sits inside the spigot of your stove. From there, connect the twin wall flue pipe above.
2. Connection via stove pipe – install a length of single wall stove pipe first, then push the adaptor into the top of the stove pipe and continue upwards with twin wall flue pipe.

Single to twin wall continental adaptor

A continental twin wall adaptor creates an easy connection of twin wall flue pipe to any European model of stove.

This Continental Stove Adaptor is used if you have a European stove collar, as the sizes are slightly smaller than a standard 5" or 6" stove collar.

• 5" continental adaptor: outside of the adaptor is 115 mm; to twin wall 125 mm (5")
• 6" continental adaptor: outside of the adaptor is 135 mm; to twin wall 150 mm (6")

The choice of the flashing depends upon:

- What kind of material material is covering the roof, and

- The pitch of the roof (0° being a flat roof, 60° a sharp roof)

Automatically we ad a roof support and -when required- a storm collar.

Approved Document J requires a minimum of 4.5m from stove collar to terminal. On low-height buildings such as garden houses this can be difficult to achieve. Shorter systems will work but may have reduced draw, especially during lighting. Most customers go for at least 3m height.

There are two ways to build your flue:

Only twin wall flue pipes

- No dangerous hot pipes in the room.

- Esthetically more pleasant.

- Better draw.

Single wall and twin wall pipes

- A single wall flue radiate warmth into the room ( this does reduce the draw somewhat as well).

- The single wall pipes can be used up till 450mm under a flammable roof (150mm for a non combustable roof).

- Single wall pipes should stay 450mm from flammable walls and other flammable materials (unless sheilded like on picture).

There are 2 types of cap to choose from:

Rain cap
Will keep vertical falling rain out of the flue. In case of side winds, rain will enter the flue. In case of a flue outside this is less of a problem, as it will not floote into the house. 

All weather Cowl
Keeps rain out of the flue. Also blocks downwinds from entering your flue. Downwinds come from higher objects in the vicinity (up to 10mtr), and without this Cowl they will blow the smoke back into your house.
