To prevent the main exchanger pipes from getting clogged with any material accumulated in the system it is
necessary to install a filter which can be inspected (Y-shaped type) with Ø 0.4mm-mesh span, on the heating return
pipe, before the boiler.
When connecting the boiler to gas supply network, install an appropriately sized and made gasket (fig. 11).
The boiler gas inlet thread configuration is not appropriate for hemp, plastic tape or similarly made gaskets.
4.5.4.
Hydraulic connections
Prior to installing the boiler, the hydraulic system is to be cleaned in order to remove impurities; they could be present in system components
and damage the pump and the heat exchanger (refer to 4.5.2 paragraph).
CENTRAL HEATING
CH flow and CH return pipes must be connected to the relevant 3/4”
f and
R
couplings on the boiler (fig. 4).
When calculating the cross section of CH system pipes, bear in mind load losses induced by radiators, thermostatic valves, radiator gate valves,
and the configuration of the system itself.
The discharge pipe from the safety valve must terminate is a safe position to atmosphere
. Should the above
precaution not be implemented and the safety valve be activated, boiler room flooding may occur.
Manufacturer shall not be held responsible for any damage resulting as failure in observing the above mentioned technical
precaution.
DOMESTIC HOT WATER
DHW flow and water mains inlet pipes are to be connected to the relevant 1/2”
CWI
and
DHW
couplings on the boiler (fig. 4).
Hardness of water supplied to the boiler may increase the plate heat exchanger cleaning/replacement frequency.
All DHW circuits, connections, fittings, etc. should be fully in accordance with relevant standards and water supply regulations.
Depending on hardness level of the water supplied, it might be necessary installing a suitable water treatment
device for domestic use and in compliance with applicable laws and standards.
Water treatment is always advisable when water supplied to the boiler is more than 20°f hard.
Water treated by commonly marketed water softeners, due to PH level induced in water, may not be compatible
with some components in system.
CONDENSATE DRAIN
Comply with condensate drain laws and standards applicable in the country of installation and which are considered herein integrally
transcribed.
When the law is not stating differently, the condensate produced by combustion, is to be routed (via the condensate drain S in fig. 4) through a
discharge system connected to the domestic sewer, which due to its basicity, counteracts flue gas condensate acidity.
In order to avoid domestic sewer odour to reach the premises, it is advisable to install an appropriate device between the discharge system and
the domestic sewer.
The condensate drain system and the domestic discharge system is to be made of adequate condensate resistant material.
Manufacturer shall not be held responsible for any damage to people, animals or objects, resulting as failure in observing the above mentioned
technical precaution.
