Instruct ons for the nstaller
4.1.4
CLEARENCES
The gas and water connect ons are located on the bottom of
the bo ler wh lst the a r ntake and flue outlet s located on the
top of the bo ler. The bo ler s suppl ed as standard w th p pe-
work ta ls to allow connect ons fac ng downwards. For nstallat on,
serv c ng and nspect on m n. 600 mm n front of the bo ler s
requ red. If th s free space s obta ned by open ng a door or
remov ng a panel, the bo ler may be nstalled for nstance n a
closed cupboard. For ease of
clearances of 0.5 cm at the s de so that the un t s easy to open,
w th a free space of 25 cm under the appl ance and 25 cm above
the appl ance, as the m n mum requ rement.

WATER QUALITY AND TREATMENT
The pH value of the water must fall w th n the follow ng l m ts:
7 < pH < 9 n non-treated water. Th s pH value s ach evable
after steady cond t ons when after fill ng the ma ns network
water ( pH around 7 ) ns de the nstallat on and the a r
el m nat on operat on has been done.Treated water hardness
must w th n l m ts 7 < pH < 8,5
If the water m ght conta n alum n um part cles, th s should
be max mum 8,5 ppm. If there s any doubt of the water
stay ng free of any k nd of debr s/contam nat on n the per od
after nstall ng, one should nstall a plate heat exchanger
to separate the bo ler c rcu t from the heat ng c rcu t. To
avo d to the max mum any presence of oxygen n the
system, we recommend to prevent as much as poss ble
a r ntake and water leakage dur ng nstallat on. Power flush
the p pes and rad ators thoroughly to remove all fluxes and
debr s before connect ng the bo ler to the central heat ng
system

CAUTION:
Bo ler damage due to corros on.
NOTE:
Damage to the nstallat on due to nsuffic ent or mproper
clean ng and ma ntenance.
Inspect and clean the heat ng system as requ red once a
year.
Carry out ma ntenance as requ red.
Immed ately remedy faults. Th s w ll avo d further damage
to the system!
DO NOT treat the water w th ant freeze.
Su table chem cals and the r use should be d scussed w th a
spec al st water treatment company pr or to carry ng out any
work (env ronmental aspects, health aspects). The spec ficat on
of the system and manufacturers recommendat ons must
be taken nto account, along w th the age and cond t on of
the system. New systems should be flushed thoroughly to
regulat ons to remove all traces of flux, debr s, grease
and metal swarf generated dur ng nstallat on. Care to be
taken w th old systems to ensure any black metall c ron ox de
sludge and other corros ve res dues are removed, aga n by
power flush ng, ensur ng that the system s dra ned completely
from all low po nts. It s mportant to check the nh b tor
concentrat on after nstallat on, system mod ficat ons, fill ng the
system and every serv ce n accordance w th these nstruct ons.
For the correct dosage and the su tab l ty of nh b tors for use
w th our bo lers and for further nformat on on water treatment
or system clean ng we adv se d rect contact w th Gassero
serv ce.
The manufacturer decl nes any l ab l ty for damage caused to
the bo ler by fa lure to nstall or nadequate nstallat on of
th s filter. Before sw tch on the bo ler, water must be c rculate at
least 2 hours for el m nat on the mpur t es from the system
trough the m cro mpur ty seperator. In the end of the operat on,
safety dra n valve must be opened for remov ng the mpur t es.
It s also poss ble to use plate heat exchangers accord ng the
system character st cs. In any case, m cro mpur ty seperators
must be used n the system n the bo ler. Before nstallat on,
carefully wash all the p pes of the system to remove any
res duals or mpur t es that could affect proper operat on of the
un t. F lter must also be nstalled on the system return p p ng to
prevent mpur t es or sludge from the system clogg ng and
damag ng the bo ler.
The plumb ng system must be cleaned us ng w th su table -
reg stered produts before start ng the nstallat on of the bo ler.
Neutral, non-ac d c and non-alkal cleaners( SENTINEL X300,
X400, FERNOX ) must be used for prevent ng the metal,
plast c and rubber parts n the nstallat on system. Please obey
the nstruct ons of the manufacturer, when us ng these type of
cleaners.
Note: Rust part cles and mpur t es n the heat ng system can
caused problems.( overheat ng, un-effic ent and no sy work)
Problems and damages due to wrong nstallat ons and wrong
plumb ng systems s out of warranty.
