2.3 LOCATION OF THE APPLIANCE
As a type C gas appliance (room sealed), this water
heater can be installed in a room, without any
restrictions for air supply and for room volume. Where
the appliance is installed in a compartment the
following ventilation is required.
When the unit is installed as a single wall fan assisted
model (not room sealed), ventilation is required for
combustion and cooling air as listed below.
The flue pipe, in passing through the wall, must not be
cemented, in order to permit subsequent maintenance
of it. For this purpose the proper rosettes, issued in the
packaging of the appliance, can be used.
To prevent ingress of water during storms, it is
recommended that the air intake and flue pipe should
have a slight gradient downwards.
Models ATI SP 80 & 120
are for wall hung
installations. For this purpose the unit is to be mounted
using the two brackets at the back of the appliance,
towards the top (wall fixings not supplied).
Models ATI SP 220, 300 & 400
are for floor standing
installation. The water heater must stand on a level
non combustible base, suitable to support the weight
of the appliance, water content and any ancillary
equipment.
ATI SP 80, 120, 220, 300 & 400
Leave a space above the water heater of not less than
200 mm, in order to allow maintenance to the flue
hood and unit.
When locating the water heater there must be
consideration to the maximum permissible length of
the flue system chosen. Where the flue pipe passes
out through a side wall, guidance on siting the terminal
is given on page
