radiators are heating up evenly and a required
temperature differential of 20ºC is present between
the boiler's heating flow and return connections.
The required water flow rate through the appliance
is 0·8 m³/h and 1·2 m³/h for the Atmos Multi 24 and
32 models respectively. The maximum permis sible
system resistance to enable the boiler pump to
achieve these flow rates is 3·1m and 2·1m
respectively. (fig 30)

9. System shutdown.
9.1 Central heating circuit.
q
Leave the appliance connected to the main
electrical supply.
q
Turn the room thermostat to its minimum
setting. The domestic water heater will remain
at its set temperature setting.
Note! On shutting down the central heating system
it is recommended not to set the room thermostat
lower than 15ºC during the winter months. To
prevent the installation from freezing it is
recommended leave all radiator valves fully or
partially open.
9.2 Domestic hot water.
q
Leave the appliance connected to the main
electrical supply.
q
Switch off the domestic hot water by pressing
the 'Hot water' button. The ‘on’ indication light
will go out. (The stored water is protected
against freezing in winter months by an
automatic frost protection that activates on a
water temperature of 15ºC).
Note! The heating and domestic hot water
installation must be independently protected from
frost. The boiler's built-in frost protection facility
will only safeguard the appliance itself.
9.3 Draining the boiler
Hot water tank
q
Turn off the cold water mains stop tap and
open the domestic hot taps.
q
Connect a flexible hose from the black drain tap
on the UV3 manifold, into the tundish. The
water from the hot water tank will now flow into
the waste pipe via the funnel of the Safety
Valve group.
Alternatively, the tank may be drained via the safety
valve on the UV3 manifold. The valve head should
be rotated through 90º and held open until water
stops flowing.
Central heating circuit.
q
Switch off the boiler electrical supply.
q
Set the three-way valve (fig 27) at the middle
position by pressing in the black button until it
locks
q
Allow the installation to drain using the
purpose fitted drain cocks.
9.5 Disposal of the appliance
The Atmos Multi is made of a number of primary
materials, especially copper, aluminium and steel.
These materials can easily be separated and
recycled at the end of the life span of the appliance.
Therefore do not throw away the appliance, but
make enquiries at your local council or a scrap
dealer.
10. Routine Inspection and Servicing.
To ensure continued efficient operation of the
Atmos Multi it must be checked and serviced as
necessary at regular intervals. The frequency of
servicing depends upon the individual installation
conditions and usage, but must be a minimum of
once per year.
The extent of the servicing required is determined
by the operating condition of the appliance when
