General information

Safety instructions

Please follow these safety instructions closely to prevent accidents and

material losses.

If you smell gas

HDo not smoke! Do not use naked

flames or cause sparks (e.g. by

switching lights or electrical

appliances ON or OFF)

HOpen windows and doors

HClose gas shut−off valve

HNotify your heating engineer/

installation contractor from outside

the building

HObserve the safety regulations of

your gas supplier (see gas meter)

and of your local heating

contractor (see commissioning/

training report).

In an emergency

HImmediately switch OFF emergency

stop switch (outside boiler room)

(except if you smell gas).

HClose the shut−off valves of the

main fuel lines.

HFor fire, use an appropriate fire

extinguisher.

Work on the equipment

Installation, initial start−up, inspection,

maintenance and repairs must only

be carried out by a competent

person (heating engineer/installation

contractor).

Before working on equipment/ heating

system, isolate its mains electrical

supply (e.g. by removing a separate

mains fuse or by means of a mains

electrical isolator) and safeguard

against unauthorised reconnection.

When using gas as fuel, also close

main gas shut−off valve and safeguard

against unauthorised reopening.

Installation of additional components

which have not been tested together

with the boiler can adversely affect the

boiler function.

Our warranty does not cover and we

accept no liability for damage caused

by the installation of such components.

Boiler room conditions

HDo not use where air is polluted

with halogenated hydrocarbons

(e.g. as in aerosols, paints,

solvents and cleaning agents)

HPrevent very dusty conditions

HAvoid rooms with permanently

high levels of humidity

HRoom should be frost protected

HEnsure good ventilation, and never

close any vents.

Work on gas equipment

This must only be carried out by an

approved contractor.

Please observe all commissioning

work for gas installations specified

according to TRGI or TRF, or local

regulations.

Repair work

It is not permitted to carry out

repairs on parts that fulfil a safety

function.

Use only original Viessmann spare

parts, or equivalent parts that have

been approved by Viessmann.

Initial start−up

Initial start−up must be carried out by

the system installer or a designated

commissioning engineer. All actual

values should be recorded in a

commissioning/service report.

Instructing the system user

The system installer must hand the

operating instructions to the system

user and instruct him/her in the

operation of the system.

Initial start−up, inspection and maintenance

Further details regarding the individual steps

Maintenance instructions

We recommend that your boiler system is maintained regularly by a heating

specialist to ensure fault−free, energy−conscious and environmentally safe

operation of your heating system.

Your boiler must be cleaned at regular intervals, otherwise the flue gas

temperature rises with increasing contamination, which leads to higher

energy losses.

We recommend the use of a flue gas thermometer.

Monitoring the flue gas temperature highlights incorrect burner settings and

the level of boiler contamination.

Excessive flue gas temperatures through boiler contamination or incorrect

burner setting reduces the system efficiency. Where necessary, clean the

boiler or adjust the burner settings.

Adjusting the pressure regulator and pressure limiter

1. Adjust the pressure limiter

response pressure a little higher

than that of the pressure regulator.

2. Secure the protective cap again on

the pressure limiter to prevent any

unauthorised adjustment at a later

time.

3. During commissioning, adjust the

pressure regulator to the required

operating pressure.

Do not alter this setting later.

Adjust the pressure regulator for

stage 1 a little higher and a little

lower for stage 2.

Note

Each pressure regulator is

equipped with a setting screw

each for adjusting the switching

point (e.g. 0.45bar) and for

selecting the switching differential

(e.g. 0.02bar), i.e., the pressure

regulator starts the burner at

0.43bar and switches it OFF at

0.45bar.

5692729 GB

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

According to the [German] Health & Safety at Work Act, steam boilers with a

safety pressure in excess of 0.5bar must be monitored. In accordance with

the conformity assessment diagram no.5 of the EU Pressure Equipment

Directive, these boilers must be categorised as classIII. Prior to

commissioning, this system must be tested by an authorised body (e.g. TÜV).

System start−up

Observe the information

provided by the suppliers of

burner and accessories.

1. Check that turbulators are fully

pushed into hot gas flues

(against their end stop)

(open boiler door).

2. Check that the boiler room

ventilation is unobstructed.

3. Check the function of the water

treatment system.

4. Fill the steam boiler with water

higher than the NW indicator.

Note

Only operate steam boilers with

suitable water; see also water

quality requirements on page26.

5. Check all fitted components, such

as pipework, valves, regulators,

pumps etc. for function and

leaks.

6. Check the fuel oil level or the gas

supply pressure.

7. Open the flue gas damper (where

appropriate).

8. Check whether cleaning aperture

on the flue outlet is closed.

9. Open the shut−off valves in oil

supply pipes (at the oil tank and

filter) or open the gas shut−off

valve, whichever is applicable.

10. Switch ON the mains electrical

isolator, the switch for the feed

water pump and the burner

ON/OFF switch, in that order.

Burner manufacturer’s

operating instructions

11. Start the boiler with a low output

(burner stage1 or partial load)

and slowly ramp up to the

required operating pressure.

12. Slowly open the steam valve

after the required operating

pressure has been reached.

13. Only enable the full burner load

at that point.

14. While the system heats up, check

the correct function of all control

and safety equipment.

15. Observe the pressure and

temperature test equipment.

16. Check the fittings for leaks and

tighten, if necessary.

17. Check the boiler door and

clean−out cover after approx.

50hours and retighten all

screws.

Note

We would recommend that you

operate the boiler constantly at the

required operating pressure.

The boiler may still be operated at

pressure, even if no heat demand

occurs for a longer period of time.

In systems comprising several

boilers, of which one is constantly

used as standby boiler, only change

the operation over in longer

intervals, e.g. during the annual

inspection of the total system.

Initial start−up, inspection and maintenance

Further details regarding the individual steps (cont.)

System shutdown

¨Safety instruction

Only open the water and steam

connections and the inspection ports

after the boiler has been completely

depressurised.

1. Close the shut−off valves in the oil

supply pipes (at the oil tank and

filter) or the gas shut−off valve,

whichever is applicable.

2. Switch OFF the burner and the

feed water pump. Pull the

connecting plug from the burner.

3. Isolate the system from the mains

power supply.

4. Close all valves.

Information regarding system shutdowns

If you do not require to use your

boiler system temporarily, maintain

the boiler water temperature by

means of the thermostat (standby) at

95ºC, to prevent corrosion through

ingress of oxygen into the boiler

water.

If you want to shut down your

heating system for longer periods of

time (several months), shut it down

completely.

HBefore taking the system out of use

for longer periods, we recommend

you take certain measures, e.g.

protecting the system against frost

or preserving the heating surfaces.

HThoroughly clean the surfaces on

the flue gas side to preserve the

heating surfaces. Then conserve

these surfaces with a preserving oil

mixed with graphite.

HFor the protection of the water

side, we recommend you flood the

boiler with degassed, oxygen−free

and treated water with low salt

content and added oxygen binders

(e.g. sodium sulphite).

Then close the steam shut−off

valve.

Check the concentration of the

oxygen binder at least every month

and replenish, if necessary. When

doing this, ensure that the binder is

well−mixed with water inside the

boiler.

HAnother option is that of dry

preservation, which is

recommended for shutdown

periods longer than 4weeks.

HWhen there is a risk of frost, drain

the boiler and the heating system

via the drain plug.

Open the shut−off and regulating

valves as well as the air vents.
