heating system, isolate the mains
electrical supply (e.g. by removing a
separate mains fuse or by means of
a mains electrical isolator) an
safeguar against unauthorise
reconnection.
Close the main gas shut-off valve
an safeguar against unauthorise
reopening.
Work on gas equipment
This must only be carrie out by an
approve contractor.
Please observe all commissioning
work for gas installations specifie
acc. to TRGI or TRF, or local
regulations.
epair work
It is not permitte to carry out repairs
on parts that fulfil a safety function.
Use only original Viessmann spare
parts, or equivalent parts that have
been approve by Viessmann.
Initial start-up

Leak test
1. Close the gas shut-off valve.
2. Loosen the screw in test nipple A
but o not remove.
3. Connect the pressure test
equipment to test nipple A.
4. By gently activating the manual
pump, create a test pressure of
approx. 100 mbar.
5. Wait approx. 5 minutes for the
temperature to level out, then
observe the pressure gauge isplay:
The test area is free from leaks, if
the isplay pressure oes not fall
by more than 1 mbar within a
further five minutes.
¨ĂSafety instruction
Check the test nipple for gas leaks.
6. Purge the gas supply pipe.
Please note:
ent the gas supply pipe and the
gas float before initial start-up.
To do this, route the vent pipe
outdoors. Check with a test
burner, whether the gas:air
mixture is combustible.
7. Leave the leak test equipment
connecte .

Further details regarding the individual steps (cont.)
Function test without gas supply
HCheck the function sequence (see
function iagram on page 25).
HSwitch ON the mains electrical
isolator (outsi e the boiler room).
HStart the burner. To o this, switch
ON the ON/OFF switch at the
control unit.
HWith the leak test equipment still
connecte , buil the pressure to
approx. 20Ămbar (gas shut-off valve
close ).
The following program must now
run (see also the function iagram
on page 25):
If a heat eman is present
(Ă" eman " lamp at the plug-in
terminal block lights up), the air
amper actuator goes from the
"close " position to stage 2 an
reverts back to air amper position
stage 1 (ST0Ă-ĂST2Ă-ĂST1).
The burner control unit sequence is
starte with the following functions:
- Burner motor starts, an
combustion chamber is purge
(approx. 30 s).
- Electric ignition is switche ON
(pre-ignition time approx. 2 s).
- Gas solenoi valve for stage 1
opens.
- Valve pressure rops.
- Gas governor switches burner OFF
(not a fault shut own).
After a safety time of 2Ăs, the
burner control unit enters a fault
shut own state, if the gas governor
oes not switch the burner OFF.
Remove the leak test equipment
an close test nipple A.

Initial start-up, inspection an maintenance
Further details regarding the individual steps (cont.)
To obtain the optimum combustion values, it is essential to adjust the burner
with the boiler heated to operating temperature (min. 60ĂºC).
Also carry out measurements at base load.
System start-up
Service instructions
Boiler control unit.
1. Check the heating system
pressure.
2. Open the gas shut-off valve.
3. Check the supply pressure (see
page 11).
4. Switch ON the mains electrical
isolator (outsi e the boiler room).
5. Switch ON system ON/OFF
switchĂB on the control unit.
If fault in icator lampĂA on the
control unit lights up, press reset
buttonĂC on the burner control
unit.
Please note:
Function sequence during initial
start-up, see pages 25 and 37.
During the initial start-up, the
equipment can enter a fault state if it
has insufficient gas in the supply line
(fault lamp on the control unit
illuminates).
entilate the gas supply line again
and reset the burner control unit.

Further details regarding the individual steps (cont.)
Checking adjustment of air damper actuator
The burner is equippe with an air
amper actuator motor with
a justable switching cams for setting
the air amper position an for
switching the solenoi valves.
During a regular shut own, the
burner air amper will rive into the
"close " position. This re uces
cool own losses.
The switching cams are locate
below the air amper actuator motor
cover. A scaling ring is locate
a jacent to each switching cam,
which enables the set angle of the air
amper to be checke .
The switching cams have the
following function:
STĂ0 Air amper close (0º)
Never alter the STĂ0 setting.
STĂ1 Air amper setting stageĂ1
STĂ2 Air amper setting stageĂ2
MV Solenoi valve stageĂ2
The switching cams for stageĂ1 an 2
are set up at the factory.
For factory settings, see the
following table.
The switching cams are a juste via
the slotte screws on the cams.

Checking static and supply pressure
Check the type of gas with your local gas supplier.
The burner is factory-set to natural gas E.
Adjust the nozzle pressure for operation with natural gas LL according to the
table on pageĂ47.
Record the gas type in the service report on page 50.
Static pressure
1. Close the gas shut-off valve.
2. Loosen the screw in test nippleĂA
but o not remove.
3. Connect the U-shape pressure
gauge.
4. Open the gas shut-off valve.
5. Measure the static pressure (max.
50Ămbar).
6. Recor the actual values in the
commissioning report on page 50.
