Installing The Boiler - Ariston Type C Installation, Servicing And Operating Instructions

11. Installing the boiler

Please check that you are familiar with the installation requirements before commencing work (Section 10).
The installation accessories described in the following list are included in the boiler packaging:
- Hanging bracket
- A paper template (showing the dimensions of the boiler with 5 mm side clearances)
- Connection tails and valves
- Screws and washers
- Connection washers
- Installation, Servicing and Operating Instructions
Method of positioning the boiler on the wall.
The paper template can be used to ensure the correct positioning of kitchen cabinets etc. It also details the commissioning
instructions.
The paper template has to be fixed to the wall and used to locate the position of the hanging bracket and the centre for the flue
hole.
Drill and plug the wall and secure the hanging bracket using the screws provided. Remove the boiler from its packaging as
shown in Fig. 16 and unscrew the two clamp locking bolts A and remove the casing (Fig. 13).
Place the boiler on the wall on the hanging bracket (Fig. 14).

Connecting the boiler to the system
- Remove the boiler casing as described in Section 18.
- Push in the tabs "P" (Fig. 14) on either side of the boiler and pivot the electrical box forward to gain access to the valve
connections
- Remove the caps and connect the boiler to the taps using the washers provided in the plastic bag.
4 x fibre washers for the C/H flow and return, hot water outlet and cold water inlet connections
1 x rubber washer for gas connection
Safety valve discharge
The pressure relief valve tube is made of copper. It should terminate below the boiler safely outside the premises. Care should
be taken that it does not terminate over an entrance or window or where a discharge of heated water could endanger
occupants or passers by.
Fill the Central Heating and DHW system and bleed air from the system as described in Section 14.
The system should be carefully checked for leaks, as frequent refilling could cause premature system corrosion or
unnecessary scaling of the heat exchanger. The pipe from the condense trap (11 Fig. 5) should be connected to a drain as
described in the relevant British regulations.
Pay special attention to not bend the condensate silicone drain pipe such as the flow will be interrupted. Please use exclusively
drain pipe material compatible with condensate products. (refer to BS 6798 : 2000)
The condensate flow can reach 2 litres / hour; because of the acidity of the condensate products (Ph close to 2), take care
before operation.
Fitting the Horizontal Flue
Attention ! Before starting the boiler, the condensate trap (11 Fig. 5) must be filled with water. Before fitting the flue l
onto the boiler, pour 1/4 litre of water in the exhaust pipe as shown in Fig. 16.
Instructions on fitting the flue can be found in Section 12.
