BOILER INSTALLATION
• Install the boiler in the boiler room at the installation site on a
foundation elevated from the floor.
• Make the boiler mechanical connections as per the installation circuit
diagram.
• Boiler installation site should comply with the related standards and
procedures. It must have a door opening towards the outside, a fresh air
inlet duct at floor level and a polluted air discharge chimney duct at ceiling
level (apart from the boiler chimney). The door and the window frames
must be of non-flammable material.
• The burner, the boiler control panel (if any) and the pre-heater
connections should be performed by eligible technical personnel in
compliance with the burner user manual and vendor installation diagram.
• The boiler must be used with the boiler control panel. (We also
recommend a thermometer to be placed on the ½” sleeve located on the
boiler return pipe.)
A hydrometer (open expansion) or manometer (closed expansion) should
be placed on the boiler outlet pipe or collector.
• The boiler may be used in an open or closed expansion system. In case
it is used in a closed expansion system; a closed expansion tank suitable
for the total boiler and central heating water volume should be used at
building static water level pressure and with adjusted gas side pressure.
The closed expansion tank should be connected to the expansion nozzle
directly on the boiler or to the boiler main outlet or return pipe provided
that there is no stop gate valve. A pressure relief valve with opening
pressure of 1,05 bars over the boiler operating pressure should be used.
• More than one boiler should not be connected to the same chimney.
• The boiler must be provided with a chimney and smoke channel in
compliance with the regulations and standards of the authorized
institutions regarding the fuel and smoke gas debit used.
• Our boiler has been designed for 90-70 C, stabilizing collector and
secondary circulation pump must be used in the system for different
temperature applications.
• The number 12 condensation water sleeve located in the figures of
pages 7 and 8 must be plugged with the boiler room output by attaching a
hose nippel and a hose to it.

In order to prevent battery corrosion, the boiler must be
grounded with,
a) 0.5m
2
, 2mm thick copper sheet,
b) 0.5m
2
, 3mm thick hot dip galvanized sheet
c) Massive copper bar electrodes.
EXPANSION TANK AND SAFETY PIPES
It is essential for the water not to be in direct contact with the air and the
temperature not to rise above 100°C in open expansion hot water heating
system. There should be outflow and return safety pipes between the
boiler and the expansion container fully and independently, without any
valves interrupting it in order to ensure the contact of water with the air
and to ensure that this connection is not cut off by mistake or due to
negligence. The safety valves should be installed without narrowing and
continually rising towards the expansion tank.
Access to the outflow safety pipe and the expansion tank can be either
from top or bottom. However the return safety pipe must be connected
from the bottom. The diameters for both pipes based on tank capacity can
be obtained from the table below. The safety pipes should never be
smaller than 1”.
