General information

Safety instructions

Please follow these safety instructions closely to prevent accidents and

material losses.

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 the equipment/

heating system, isolate the 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

the main gas shut-off valve and

safeguard against unauthorised

reopening.

Work on gas equipment

This must only be carried out by an

approved contractor.

Please observe all commissioning

work specified for gas installations to

TRGI or TRF and all local regulations.

Please observe all commissioning

work specified for gas systems.

Repair ork

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

The 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.

¨ĂSafety instruction

Denotes information which must be

observed to prevent accidents and

material losses.

Initial start-up, inspection and maintenance

Initial start-up

Operating instructions, service instructions ć control unit and burner

1. Check that the boiler room

ventilation aperture is open.

2. Check the inlet pressure of the

diaphragm expansion vessel.

If the inlet pressure of the

diaphragm expansion vessel is

lower than the static system

pressure, top up with enough

nitrogen to raise the inlet pressure

higher than the static system

pressure (0.1 to 0.2Ăbar).

3. Open the check valves.

4. Top up your heating system with

water and vent until the filling

pressure is higher (0.1 to 0.2Ăbar)

than the inlet pressure of the

diaphragm expansion vessel.

Permiss. operating pressureĂ Ă Ăbar

. . .

5. Mark this pressure on pressure

gaugeĂA.

6. Return the check valves to their

operating position.

7. Open the oil or gas shut-off valves.

Operating and service documents

1. Complete and detach the

customer registration card:

HHand the system user this part

for safe-keeping.

HRetain the heating engineer part.

2. File all parts lists, operating and

service instructions in the folder

and hand this over to the system

user.

9. Checking diaphragm expansion vessel and system pressure

Observe the diaphragm expansion vessel manufacturer s instructions.

Carry out this test on a cold system.

1. Drain the system or close the cap

valve on the diaphragm expansion

vessel and reduce the pressure

until the pressure gauge

indicatesĂ"0".

2. If the inlet pressure of the

diaphragm expansion vessel is

lower than the static system

pressure, top up with enough

nitrogen to raise the inlet pressure

higher than the static system

pressure (0.1 to 0.2Ăbar).

The static pressure corresponds to

the static height.

3. Top up the heating system with

water, until the filling pressure of a

cool system is higher (0.1 to

0.2Ăbar) than the inlet pressure of

the diaphragm expansion vessel.

Permiss. operating pressure: Ăbar.

10. Checking the tight fit of thermal insulation and cable

grommets

11. Checking mixer for easy operation and leaks

1. Remove the motorised lever from

the mixer handle, and check the

mixer for ease of movement.

2. Check the mixer for leaks.

Replace the OĆrings if the mixer

leaks.

3. Snap the motorised lever into

place.

12. Checking the draught stabiliser (if installed)

Release the latch on the control disc.

The control disc must swing freely

during burner operation.

13. Burner settings

Burners up to 63ĂkW Burner service instructions

Burners from 80ĂkW

Adjust the max. burner oil or gas

throughput so that the stated

maximum rated boiler output will

not be exceeded.

Note that, for multi-stage or

modulating burners, the flue gas

system must be suitable for the low

flue gas temperatures which may

arise during partial load operation.

Select the lowest partial load stage,

also taking the respective flue gas

system design into consideration.

Two stage

The following minimum output is

required for the base load stage to

protect the system against dew point

corrosion:

Modulating

For oil-fired operation, the minimum

boiler water temperature is 60ĂºC and

for gas-fired operation 65ĂºC.

Adjust the return temperature raising
