INSTALLATION
Gas Supply
The gas installation and tightness testing must be in accordance
with the requirements of BS6891. Ensure that the pipe size is
adequate for demand including other gas appliances on the same
supply.
Electrical Supply
The appliance requires an earthed 230V - 50 Hz supply and must
be in accordance with current I.E.E. regulations. It must also be
possible to be able to completely isolate the appliance electrically.
Connection should be via a 3 amp double pole fused isolating
switch with contact separation of at least 3mm on both poles.
Alternatively, a fused 3 amp, 3 pin plug and unswitched socket
may be used, provided it is not used in a room containing a bath or
shower, it. It should only supply the appliance.
Automatic by pass
Ariston recommend that an automatic by pass is installed a minimum
of 1.5 metres away from the boiler to ensure the minimum required
flow rate is achieved at all times. Additionally the design of the
system and its controls must ensure that an adequate temperature
diff erential is met, and should be such to prevent boiler cycling.
Feed and vent pipework
The feed and vent pipework from the boiler to the F & E (Feed &
Expansion) tank should be configured as shown in the fig. below.

Note:
The distance between the cold feed and the open vent pipe shall
be no more than 150mm.
The cold feed must be inverted as shown.
The open vent pipe must be a minimum of 22mm diameter.
The cold feed pipe must be a minimum of 15mm diameter.
The cold feed and open vent pipes must rise continuously and be
unrestricted.
• The minimum distance from the top of the boiler to the bottom
of the F & E tank shall be no less than 2m. Whilst the maximum
distance shall be not more than 27m.
The distance between the bottom of the F & E tank and the
highest point of the open vent must be no less than 500mm.
The flow and return pipes from the boiler must rise continuously
and be unrestricted.
The supply of water to the F & E tank should be taken from the
mains water supply via a suitable float operated valve. While the
supply from the F & E tank to the boiler/heating circuit (via the
cold feed) shall be unrestricted.
The F & E tank must be adequately supported and installed in
accordance with relevant Building Regulations.
Pump specification
The pump should be fitted on the flow pipe from the boiler and have
isolating valves each side. A variable duty pump should be set to
give a temperature differential of no greater than 20ºC.
Draining tap
A draining tap must be provided at all the lowest points of the
system which will allow the entire system to be drained. A drain tap
must also be installed on the flow and return pipes immediately
above the boiler to ensure complete draining of the primary flow
and return is possible.
Drain taps shall be to the current standard of BS 2879.
Sealed water systems
A sealed system kit is available from Ariston. Installation instructions
are supplied with the kit.
