Safetv Valves

Drill and plug the wall and secure the hanging bracket using

the screws provided (refer to the paper template drawings).

Remove the boiler from its packaging as shown in (fig. 8) and

remove the outer case as shown in (fig. 9).

Please note: If the pre-piping jig has been used it must be

removed before attempting to hang the boiler.

Place the boiler on the wall on the hanging bracket.

Connecting the boiler to the system

- Push in the tabs P (fig 10) on either side of the boiler and

pivot the electrical box forward to gain access to the valve

connections.

- Remove the yellow caps and connect the boiler to the taps

using washers provided in the plastic bag.

3 x fibre washers for the C/H flow and return and hot water

outlet connections

1 x fibre washer and mesh filter “F” for the cold water inlet.

1 x rubber washer “R” for gas connection.

Using (fig. 10) for reference, connect the gas and water pipes

to the valves located at the base of the appliance using the

tails provided. There is a 190 mm space between the valves

and the wall to make these connections.

Provision must be made to fill and recharge the system

pressure. This can be achieved using a filling loop or other

methods approved by the local water authority.

There are two pressure relief valves fitted to the CALYDRA.

The DHW pressure relief valve connecting pipe is supplied

attached to.the valve and the CH pressure relief valve tube is

clear silicone and is packed with the boiler. They should

terminate together below the boiler over a tundish or a 28 mm

to 22 mm reducer (see P 17, fig 10) which should in turn

discharge safely outside the premises. Care should be taken
