7. BOILER INSTALLATION INSTRUCTIONS
7.1. BOILER INSTALLATION – OVERAL INFORMATION
The hot water boilers from series BiSolid Comfort 03/04/05 must be initianted into operation by
authorized servicing technicians. The existing network of authorized servicing organizations
which comply with this condition is able to take responsibility for all boiler installations, their
initialization in operation and warranty repairs.
The boiler is designed to supply heating systems with pressure up to 400 kPa by using water,
which must compy to the standard requirements (under no circumstances the water can be
acidic, i.e. it must have hydrogen exponent pH>7 and minimum carbon hardness). The heating
system must be designed in such way that the hot water circulates at least through some of
the radiators at all times.
We do not recommend the usage of antifreeze liquids because of their unsuitable properties.
Such liquids have decreased heat-exchanging capabilities, high volume expansion and
harmfull components.
Before final installation, the distribution pipelines of the heating system must be rinsed several
times with water under pressure. In old, already used systems, the rinsing has to be performed
in opposite direction to the heated water circulation. In new systems all radiators have to be
cleaned from erosive materials and rinsed with warm water under pressure.
We recommend installation of precipitant on the boiler entrance (i.e. on the boiler’s hot water
return pipeline). The precipitant should be designed with availability for emptying on regular
intervals, without necessity of draining too much hot water. The precipitant can be combined
with filter, but the filter itself is not enough to secure adequate protection.
Warning
The system must be connected to open type expansion tank, for safety
reasons.
Any of the stopping fittings must not be connected to the inlet or the safety
outlet pipelines.
For increasing the system safety a bypass line must be installed on the inlet
and outlet line of the circulations pump, as presented on the diagrams.
The bypass line valve must be closed when the boiler operates normally.
The bypass line valve can be used when there are problems with the power
supply and must be opened if there is any risk of heating system water
overheating, caused by power supply failure or another problem.
The pipelines diameter installed in the bypass line must be at least equal of the
water supply pipeline.
UPS (uninterruptible power supply) can be used for prevention of power supply
failures.
Warning
All problems (faults) with the boiler caused by clogging with dirt from the heating
system or faults caused by clogging are not covered by the product warranty.
