Note regarding internal air-flue systems.

It is recommended that the boiler is sited on or next to an external wall so as to

negate the need to use a void or enclosure as a route for the flue system. Where

this is not possible the following applies:

CORGI have issued a Guidance Document on the safe installation of flue

systems within a dwelling. This is a Technical Bulletin reference TB200, and can

be downloaded from the internet. In brief this requires the air-flue system to be

*accessible for visual inspection* by a service engineer. Particular concern

focuses on the joints, supports, material and correct slope of the flue installation,

which should all be in accord with the instructions given in this document and with

good practice. We recommend that the guidance given in this document is

adhered to, especially in the case of twin pipe flue systems.

5.6 Flue discharge and air supply

A number of different flue systems are available from Atmos for use with this

appliance:-

• 60/100mm concentric system, comprising a standard through the wall flue

kit or an extended system.

• 80/125mm concentric system.

• 80mm aluminium twin pipe system

• 80mm PPS plastic twin pipe system.

The twin pipe systems enable separate air intake and flue pipes to be fitted to

the appliance.

Maximum lengths are specified in § 5.6.2, § 5.6.4 and § 5.6.6, and must not be

exceeded.

Other special flue arrangements covering Prefabricated Chimneys and Multi

Storey flue systems are included in § 5.7 to 5.9.

5.6.1 60/100mm Concentric Standard through the wall Horizontal

IMPORTANT!

Using the concentric adapter set (see photo), the standard two-pipe

connection can be changed into a concentric connection.

1. Seal the open air supply connections in the appliance with the sealing

cap delivered with the set (item C in photo).

2. Remove the sealing ring around the flue discharge in the appliance, as

shown below.

3. In its place, fit the sealing ring ø 116 x 110 mm (item B in photo).
