Changeover from natural gas H to natural gas L
The changeover to a low calorie natural gas is simple.
Only a check or correction of the CO
2
(O
2
)
value at
max. and min. output must be carried out (see chap-
ter 4.3.7).
Changeover from natural gas H
to propane liquid gas
Compliance with the special local pro-
visions (VKF/DVGW/ÖVGW) for ope-
rat ing a boiler on liquid gas is impera-
tive in each case.
The propane liquid gas conversion kit comprises:
- 1 yellow sticker “Changed too the set gas type:
Liquid gas“ for the boiler rating plate
- 1 gas pressure deflector „Liquid gas“
A) With an already connected boiler:
- Close the gas shut-off valve
- Place the system deflector in the operating panel
to “0“
B) Take off the boiler hood.
C) Remove the gas pressure deflector „Natural gas“
and install the new gas pressure deflector „Liquid
gas“. Wire up the gas pressure deflector (AMP
connector at position 1 and 3).
D) Affix the yellow sticker „change to the set gas type:
Liquid gas“ to the boiler rating plate.
E) with boiler already connected:
- open the gas valve
- place the system deflector to „I“
F) Set the CO
2
(O
2
)-content according to. 4.3.7 at
rated and minimum output to CO
2
= 9,9 - 10,2 (O
2
= 5,9 - 5,5) Vol.-% (dry).
Handing over to the user
4.4
Instruction the user
4.4.1
Obtain from the user a written confirmation that
- he has received adequate instruction in the correct
operating and maintenance of the system,
- he has received and read the operating and main-
tenance instructions, plus additional documents
concerning the burner, heating controller etc.,
- and is consequently sufficiently familiar with the
system.
A pre-printed form (in duplicate) for this confirma-
tion is to be found on last page of these installation
instructions.
Also available on request for flow with the boiler are
copies of the official description for submission to the
supervisory authorities or for obtaining a permit from
the local technical inspectorate.
The operating instructions and technical in-
formation are always to be kept in the boiler
installation room.
Checking the water level
4.4.2
The customer should be informed of the values be-
tween which the movable pointer on the pressure
gauge may alternate. Refilling and bleeding the air
from the system are to be demonstrated.
Maintenance
4.4.3
On hand-over the customer is to be informed that
checking and cleaning of the gas firing is to be car-
ried out at regular intervals - normally at least once
per year - by the licensed installer or the responsible
after-sales organisation. The conclusion of a main-
tenance agreement is also important for economical
operation in the sense of the energy-saving laws
and by a permanently correct burner setting avoids
complaints with the statutory inspection of flue gas
loss and pollutant emissions.
Decommissioning
5.
The following steps are to be taken if the compact
heating controller is to be placed out of operation
for several weeks:
Clean the boiler heating surfaces and have your boiler
servicing agent apply a conservation agent. Your
chimney-sweep technician will eagerly consult you.
Where there is a frost hazard, drain your system
in accordance with the instructions of your heating
installer or add frost according to the instructions of
the heating installer.
