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.
