Commissioning the system

Details provided by the burner
manufacturer and regarding
accessories
01. Check that the turbulators (if instal-
led) are fully pushed into the hot gas
flues (open the boiler doors).
02. Check that the boiler doors and
cleaning apertures at the back of the
boiler are closed.
03. Check that the installation room
ventilation is unobstructed.
04. Check the function of the water
treatment system.
05. Fill the steam boiler with treated
water higher than the low water indi-
cator level.
Note
In accordance with the TRD 611,
only suitable water must be used
with the steam boiler.
For water quality guidelines,
see from page 22.
06. Check all fitted components, such
as pipework, valves, controllers,
pumps etc. for function and tight-
ness.
07. Check the fuel pressure.
08. Open the flue gas damper (if instal-
led).
Commissioning, inspection, maintenance
09. Open the shut-off valves in the oil or
gas line.
10. Switch ON the mains isolator, the
switch for the equipment required
for the boiler system and the burner
control switch in this order (observe
the burner manufacturer's operating
instructions).
11. Start the boiler at a low heating out-
put and gradually heat up to a pres-
sure of approx. 3 bar below operat-
ing pressure.
Version with integral economiser:
To prevent steam hammer during
heat-up, initiate a feedwater flow
through the economiser several
times, for example by manually acti-
vating the blow-down valve.
12. Vent the boiler at the air vent valve
during heat-up until steam is expel-
led. Then close the valve.
Danger
Expelled medium can lead to
scalding.
Ensure the medium is
drained off safely.
13. Slowly open the steam valve after
the required steam pressure has
been reached, otherwise there is a
risk of steam hammer.
14. While the system heats up, check
the correct function of all control and
safety equipment.
