2. General Information.
2.1 The Atmos Multi is a wall mounted, fully
automatic gas fired condensing combination boiler
designed to provide 'unvented' domestic hot water at
mains pressure via an integral hot water storage
cylinder.
2.2 Classified as an 'Unvented hot water system', the
installation of the Atmos Multi falls within the scope
of the Building Regulations 1995 (Part G.). These
require that a competent person as defined in the
Approved Document G3 must only undertake the
installation of an unvented system.
2.3 For central heating applications the Atmos Multi is
suitable only for use on a fully pumped, pressurised,
sealed primary system with a design (cold) pressure of
between 0.5 and 2.5 bar.
2.4 The boiler may be installed in any room or internal
space without the need for purpose made ventilation,
although attention is drawn to the current IEE Wiring
Regulations with respect to installation in a room
containing a bath or shower. In such installations, it
must not be possible for a person using the bath or
shower to touch any mains electricity fed switch or
boiler control.

Where appropriate and always in areas
of Hard Water (hardness in excess of 200ppm), an
approved water conditioner device must be fitted in

can supply a suitable conditioner for fitting to the

2.6 The Atmos Multi is suitable to accept pre-heated
water such as that supplied from solar panel
installations.
2.7 Where the boiler is intended for use on Propane
gas, the boiler must not be installed in a room or
internal space below ground level.
