• In cold climate regions, required measures should be
taken to prevent boiler and condenser tank water
temperature dropping to freezing temperature.
• Except before firing, the boiler should not be fed cold
water. It is recommended not to drop below 70
o
C in any
case. To be used in processes where condenser return is
low or nil and at times when condenser water
temperature is low; heating of the condenser tank
should be ensured by connecting the condenser tank to
steam heater line.
• The boiler water level should be checked continuously. If
the water level cannot be seen properly or the gage is
defective, the burner should immediately be stopped
and the gage glass should be cleaned or the gage error
should be investigated and corrected. It should be
frequently checked that the gage valve and connection
pipes are not blocked internally.
• Boiler feed devices should always be in working
condition and at least once in each shift the device
discharge valve should be opened to discharge possible
deposits and pipe clearance should be inspected. Once a
month, the feeding device body should be opened,
checked, any existing deposits should be cleaned, the
connection pipes and valves should be checked with a
wire for blockage. Measures should be taken to prevent
use of hard water that causes deposits or for more
regular utilization of the Water Softener Device.
• In abnormal situations, for example when water level is
rapidly dropping, steam pressure is rapidly rising, when
redness/bending at some parts of the boiler is observed
or any leakage or drain is seen, the burner should be
stopped immediately. The steam should be let off from
the discharge and the authorized services should be
notified. During this time, the boiler should not be fed
with fresh water.
• If the burner does not run, do not press the computer’s
reset button more than twice and call authorized burner
service.
• If leaks and drains are observed on burner fuel
connections and transfer lines, the burner should be
immediately stopped and line valves should be closed.
In the case of natural gas or LPG usage, utilize a

leakage detector device in the boiler room and an
automatic fuel cut-off system on the main inlet.
• In the case of LPG usage, when you observe icing and
dew on fuel pipes due to liquidizing of residual gas in
fuel pipes, especially on cold days, do not absolutely
operate the burner. The LPG should be safely discharged
from the drain tap. (Liquidizing may also form at normal
times due to gasification level control or line regulator
problem.)
• The boiler door should absolutely not be opened before
the burner is stopped and electric power is cut.
PREPARATION OF THE BOILER FOR OPERATION AND
FIRST FIRING
Initial preparations
Before a boiler that is to be newly put in operation or on which
maintenance-repair work has been performed is fired, both the
water side and the gas side (such as furnace inside, chamber,
chimney gas channels, air channels, air heater, burner
combustion chamber) should be inspected thoroughly; should be
cleaned of tools sets, pieces of cloth, iron pieces, oakum etc.
Residues such as dust, soot, slag should be removed by washing
or sweeping.
Any existing loose places in boiler internal parts and all other
loose places such as holders, clamps and similar, should be
tightened. After this, all inlets should be closed and manholes
should be tightened using appropriate gaskets.
It should be ensured that all hardware in the fuel equipment and
chimney draught system function correctly, any existing flaps
should be controlled for ease of opening and closing. If automatic
combustion controls or other automatic controls exist, all
adjustments, tests and all calibrations related to these should
Have the vapor system installed by
authorized personnel!
