COMMISSIOnInG
E)
For a boiler which is already connected:
- Open the gas cock
- Energise the heat generator (e.g. main switch, fuse)
and set blocking switch to “I”.
F)
Adjust fan speed in accordance with parameter list "Ad-
justments for liquid gas" (parameters 35-41).
!
DANGER
Danger of explosion due to leaking gas con-
nection.
• Following installation of the boiler, check
the gas connection for leaks.

Please comply with the following points when exchang-
ing or readjusting the valve VR 4615V:
The valve supplied as a spare part is open and must be
set in advance. To do this, turn the screw marked in red
one turn (360°) to the right. In this way, you are near the

Now install the valve correctly and make the fine setting
of the gas quantity according to chapter 4.6.3.1. The pre-
set information relates to natural gas

flue gas (flue gas measurement)
Important basic note:
If the minimum gas flow pressure falls below the minimum
li mit (chapter 4.5) (e.g. as a result of clogged gas filters,
under- dimen sioning of the gas supply line), the boiler will
not reach the nominal output defined by the manufactur -
er. If this happens, please inform your gas company.
NOTICE
If the gas flow pressure of natural gas is be -
low 18 or above 50 mbar, no setting and no
com missioning can take place.
The Honeywell multifunctional valve (Fig. 05) has two
measuring nipples for measuring the gas in let pressure

and gas outlet pressure

.
The gas/air mixture is prepared by a state-of-the-art, com-
plete unit consisting of mixing device (Venturi), multifunc-
tio nal valve and fan.
