Preparing and starting up the boiler
Before actually starting up the boiler, the
following basic tasks have to be carried
out:
a) Fill up the heating system with water.
Check the water pressure on the boiler’s
pressure gauge.
b) Check the boiler’s connection to the fu-
mes exhaust system,
c) Open the gas isolation valve and let
gas into the boiler. Measure the supply
pressure. Bleed the gas connection
pipe.
d) Set the thermostats:
– emergency thermostat (open systems
to 97°C – factory setting, closed sys-
tems with expansion vessel may have
the temperature set to 105°C),
– fumes thermostat to 70°C (can be set
within the range 70-110°C. Setting
change must be approved by the manu-
facturer),
– operating heating water and UHW ther-
mostat (when auxiliary reservoir is used)
is set to approximately ¾ of their respe-
ctive full ranges. The operating heating
water thermostat can be set within the
range 0-85°C.
e) Press the power mains switch. When
using an RVA 43.222 control unit, set
the mode to WINTER. The boiler ignites
and starts heating the UHW. After rea-
ching the set temperature, it starts hea-
ting the heating system water. With the
boiler running, check the entire gas rou-
te joints for leaks, e.g. using a foam-for-
ming solution. Any leaks (caused by the
boiler’s transportation) must be repaired
and the inspection repeated.
f) At the end before starting the boiler up,
check and if necessary adjust the gas
supply pressure at the outlet from the
gas shutting-valve.
The adjustment is done using the regula-
tion elements on the gas shutting-valve.
Putting the boiler into operation
1. Open the gas supply valve and the
heating system water supply valve.
Set the I/II switch to the II position – man-
ual operation. Set the boiler thermostat to
the maximum temperature.
2. Turn on the main switch on the boiler’s
control panel. Connection to power supply
is indicated by the green light.
3. If everything is OK, the ignition burner
is ignited. The burner’s ignition electrode
sparks for 25 seconds by default. The igni-
tion burner starts up the boiler in reduced
output. If the burner does not ignite within
the ignition cycle, a control light on the pow-
er mains modules will light up, signalling a
fault (see Fig. 29). If repeated attempts to
ignite the burner fail, the main switch must
be turned off and the fault diagnosed and
repaired (refer to Chapter 11), and then
the whole process repeated.
4. The boiler’s thermal output can be set
and adjusted as described in Chapter
7.3.
5. Perform a heating test:
– set the I/II switch to the I position,
– on the Albatros control unit enable func-
tion “Chimneysweep”,
– carry out the heating test.

First live heating test
The first live heating test is performed by
running the boiler for a short while after its
final connection to the heating system.
Set the boiler’s controls (operating con-
trols, room control unit) so that you reach
as high heating water temperature as pos-
sible with as few boiler shutdowns (switch
offs) as possible. Keep the entire system
(the boiler as well as the heating system)
in these conditions until it stabilises itself
(i.e. until the temperature even in the point
furthest away from the boiler stabilises),
and then let it run for at least an hour.
Shut the boiler down. Write down the boil-
er pressure. Once more carefully bleed
the system and then pressurise it to the
value you have written down.
Let the boiler cool off. Monitor whether
with the dropping temperature the pres-
sure does not drop down significantly. If
the pressure does drop, look for leaks, re-
pair them and repeat the live heating test.
Specialist Maintenance
Part of maintenance (servicing) are also
repairs. These are one-off specialised
works performed immediately whenever
a reason for them occurs (defect, error).
Errors are repaired by replacement, using
correct, exclusively manufacturer’s origi-
nal or by the manufacturer recommended
parts and components.
Whenever a defect occurs, it is forbidden
to continue running the boiler on a perma-
nent basis for the purpose for which it is
designed!!!
When maintaining and repairing the boiler
(or its parts), measures must be taken to
prevent injuries, particularly by electricity,
by fall (movement) of objects and by burn-
ing.
If mechanical maintenance is performed
by people without electrician qualification,
it is absolutely essential before works on
the equipment are commenced to discon-
nect it from all power supplies, and this not
only with a switch (main, power mains),
but also by disconnecting the supplies
(e.g. with circuit breakers, etc.)!!!
Apart from Operating Instructions, the
tasks performed as part of specialist pre-
ventative maintenance are detailed in the
Boiler Service Book.
Converting to Different Fuel Type
Converting to a different type of fuel (natu-
ral gas, propane gas) is possible only in
models 65 and 85 KLO / KLO EKO. The
conversion to a different fuel can be done
by the following procedure.
Important:
This conversion must be done
exclusively by an authorised service.
The procedure converting to a different
type of fuel:
1. Shut the power supply before the boil-
er.
2. Disconnect the boiler from power sup-
ply.
3. Fold the boiler’s front panel.
4. Remove the jets from the burner con-
sole and replace them with jets of appro-
priate diameter depending on the boiler
type and kind of fuel (refer to the table
provided).
5. Replace the pre-ignition burner jet. Use
jets for the given type of fuel (see Table
X).
6. Honeywell gas valves have in the bot-
tom right corner a black plug. Underneath
the plug is an adjusting valve for the start
up gas supply. Insert into the indented ar-
