Heating systems with an open expansion tank enable direct contact of heating water with the atmosphere. Within the heating period,
expanding water in the tank absorbs oxygen that increases corrosion effects and at the same time water is being significantly evaporated.
Only water prepared to the valued according to ČSN 07 7401 may be used for addition.
12.
Deaerate the heating system.
13.
The boiler must be properly earthed.
An external protective clamp serving for earthing is installed on the rear part of the boiler.
14.
Fill up the heater with water
(provided it is connected). In case of a long water distribution, it is necessary to insulate the pipeline to
reduce heat losses.
15.
After filling-up the system with water,
switch-over the control lever of the Honeywell V 4044F three-way valve from the MAN-OPEN
position to the AUTO position
, see fig. No. 26 (as far as the hot water preparation is installed)
16.
Connect the outdoor thermostat of 950 01 type
(only for boilers equipped with a two-stage gas valve). The outdoor thermostat has to
be placed on the north or north-east side of the facility. At mounting and connection, proceed according to instructions specified in the
manual for the thermostat. The switch-
off temperature of the thermostat is set to 0 °C and, as necessary, it is possible to change its
settings in the range of 0
8 °C.
17.
Connect the selected type of regulation
according to the attached manual.
18.
After boiler unpacking, put plastic foil, a wooden pallet and cardboard package into corresponding waste containers.
During the heating season it is necessary to maintain the constant volume of heating water in the heating system and be particular in the
heating system is deaerated.
Water from the boiler and the heating system mustn't be discharged or withdrawn for using, except the
necessarily needed cases, such as repairs and so on. Emptying heating water and filling-up of new water increases a danger of corrosion and
creation of water stone. If it is necessary to
add water into the heating system, please only add it to the cooled boiler
, in order to prevent
bursting the section.

Commissioning - instructions for contractual service organizations
The boiler commissioning, heat output setting and any interference with boiler electric part or connection of additional control
elements can only be done by a contractual service organization authorized to do these activities.
11.1
Verification activities before commissioning
Before the boiler commissioning it is necessary to check:
1.
Filling the heating system with water (check the manometer).
2.
Thermostat settings:
-
boiler thermostat 45
– 85 °C (in case of any superior regulation, it is recommended to set temperature to 85 °C );
-
heater thermostat (if connected) 0
– 90 °C; for a sufficiently fast hot water heating the TK boiler thermostat must be set to 85 °C.
3.
Gas input pressure before entering the boiler and deaeration of the gas connection.
4.
Connection to electric network and switching of the control thermostats ČSN 33 2180 Art. 6.2.2. The sockets are to be connected in a
way making sure that the protective plug is upwards and the phase are connected to the left hand side socket when looking on it from the
front. The same applies to the double sockets.
5.
Release the air-relief screw of the automatic air-relief valve.
6.
Connect it to the chimney or to the flue gas ducting in case of the forced flue-gases exhaust.
7.
Sparkling (perform it at the closed gas supply into the boiler):
-
check by listening whether there is any sparkling on the ignition electrode of the ignition pilot burner;
-
sparkling time depends on the used automatics;
-
with regards to the closed gas supply, failure has to be signalized;
-
carry out unblocking of the automatics by pushing the
„RESET“ button on the network module.
11.2
Commissioning
A boiler equipped with only a network module or a room thermostat (works without a superior regulation):
1.
Open the gas seal and the water "shut-offs" in the heating system.
-
switch-on the main switch;
-
switch-over the power switch to the position I in case of the use of an outdoor sensor; otherwise select the power depending on your
needs.
2.
Provided all is OK, the ignition pilot burner will be ignited. The main burner will then ignited from the ignition pilot burner. If the igniting
cycle has run over but the burner is not ignited, a failure signalling on the electric panel will light up. As far as no ignition is repeatedly
performed, ) and it is necessary to switch-off the main switch, find out and remove the failure (see chapter 15) and afterwards repeat the
procedure.
3.
Check absence of gas escape.
4.
Perform setting and adjustment of the thermal power of the boiler.
5.
Carry out a heating test.
The boiler equipped with superior regulation
1.
Open the gas seal and the water "shut-offs" in the heating system.
2.
Switch-on the main switch on the electric panel of the boiler. Connect the boiler to the electric supply network is signaled by a green lamp
lightening
3.
Switch-over the main switch to the position I (automatic operation).
4.
As far as all is OK, automatic ignition of the low power is performed; in case of requirement of the superior regulation for higher
temperature, the nominal power will be ignited. If the igniting cycle has run over but the burner is not ignited, a failure signalling on the
automatics will light up. As far as no ignition is repeatedly performed, ) and it is necessary to switch-off the main switch and remove the
failure (see chapter 15) and afterwards repeat the procedure.
5.
Check absence of gas escape.
