14. Pipe installation
The installation must be carried out in accordance with current heating and
DHW standards. The product must be connected to an expansion vessel
in an open or closed system. Do not forget to flush the heating circuit
clean before connection. Perform all the installation settings based on the
description in the chapter on “First start”. See the chapter on the EcoZenith’s
functions in the section for the property owner for more information on the
function of the various parts of the system.
This chapter contains the main connections for the EcoZenith, plus additional
installations such as heat pumps, tanks, solar energy, pool, passive cooling,
bedrock recharging, DHW circulation and external gas, oil or pellet boiler.
The instructions for the relevant additional product should be followed.
Refer also to the “Electrical installation” chapter.
Connections, placement and dimensions
See Technical data in the section for the property owner.
Pipe connections on the unit
Connect the pipes as shown in the schematic diagram for pipe connections.
Also refer to Technical data in the section for the property owner for
connection dimensions and placement. If annealed copper pipe is used, fit
support sleeves.
Circulation pumps – heating circuit
The circulation pumps are fitted to the primary flow pipe from the EcoZenith
to the respective radiator systems and receive their power supply from the
EcoZenith (refer to the "Electrical Installation" chapter).
Mixing valve
Install a mixing valve where there is outgoing tap DHW in order to avoid the
risk of scalding at the property’s tap DHW points.
Safety valves
The EcoZenith’s safety valves for the tap water circuit and boiler are
packaged separately. Connect the waste pipes to the waste system
directly to the floor gully or, if the distance is more than two metres, to a
funnel. Water may drip from a connected waste pipe. The waste pipe must
incorporate a fall towards the floor gully, be installed so that there is no risk
of freezing and be left open to the atmosphere/without pressure. The length
of the waste pipe may not exceed two metres, unless in these cases it exits
into a funnel.
Filling valve – heating circuit
Fit a filling valve between the cold water connection and the radiator return
pipe, or between the cold water pipe and the expansion pipe. The filling
valve must be provided with a non-return valve (to prevent backflow).
