Installation Instructions
Boiler installation - General information
S.MAX boilers must be put into service by an authorized services. A network of authorized service
organisations which meet these conditions is available for all boiler installations, putting them into service
and for warranty repairs. These networks are organised by Önmetal's agreed distributors outside of Turkey.
The boiler is designed to supply heating systems with gauge pressure up to 400 kPa which use water that
meets the requirements of related standarts ( under no circumstances may the water be acidic, i.e. it must
have
p
H>7
,
and it should have minimum carbon hardness
)
.
have
pH>7
,
and

.
The heating system must be designed in such a way that hot water can circulate all the time through at least
some of the radiators.
Antifreeze fluids – because of their unsuitable properties, we do not recommend to use them.They have a
reduced ability to transfer heat, have large volumetric expansion, age and damage rubber components. If
under concrete circumstances there is no other option how to reliable prevent .

Before final installation, the heating system distribution piping must be flushed several times with pressurise
d
water. In old,already used systems,the flushing must be done in opposite direction to the hot water circulation.
In new systems, all radiators must be cleaned from conservation material. and rinsed with warm water under
pressure.
We recommend installing a sludge trap upstream of the boiler (i.e. on hot water return pipe ). The sludge trap
design should allow emptying in regular intervals, without the need to drain a lot of hotwater. The sludge trap
may be combined with a filter; however, a filter alone will not provide an adequate protection.
