Standards And Regulations - Wolf COB Installation Instructions And Technical Manual

COB / COB-TS oil condensing boiler
Two-stage oil condensing boiler with electronic ignition and
electronic flue gas monitoring, for low temperature heating
and DHW heating in heating systems with flow temperatures
of up to 85 °C and a permissible operating pressure of 3 bar.
The COB complies with the following regulations:
EC Directives:
- 92/42/EEC Efficiency Directive
- 2004/108/EC EMC Directive
- 2006/95/EC Low Voltage Directive
DIN / EN Standards:
EN 230, EN 303, EN 304, EN 15034, EN 15035, EN 12828,
EN 61000-3-2, EN 61000-3-3, EN 61000-4-3, EN 55014-1,
EN 60335-1, EN 60335-2-102, EN 60529
Stratification cylinder type TS made of steel S235JR with
connections to the on-site pipework.
Corrosion protection through enamel coating on the inside
of the cylinder as per DIN 4753 and additional corrosion
protection through a protective magnesium anode.
Open flue oil condensing boilers must only be
installed in a room which complies with the
appropriate ventilation requirements. Otherwise
there is a risk of asphyxiation or poisoning.
Read these installation and maintenance
instructions before installing the boiler. Also
take the technical guide into consideration.
Note: The DHW temperature should be limited to a
maximum of 55 °C if the hardness of the hot
water is more than 2.86 mmol/l. A reduced DHW
temperature prevents excessive scaling. This
cuts the level of maintenance and energy input.
Obtain the permission of your local flue gas inspector and
the lower water authority prior to the installation of Wolf
oil condensing boilers.
Wolf oil condensing boilers must only be installed by a
recognised heating contractor. This heating contractor
will also be responsible for the proper installation and the
commissioning of the heating system. The DVGW Code of
Practice G676, boiler room guidelines or Building Regulations
relating to the construction and installation of central boiler
rooms and fuel storage facilities apply.
The following regulations, rules and guidelines must be
observed during installation:
- Energy Savings Act (EnEG) and related directives
- EnEV Energy Savings Order
- Technical regulations for oil installations IWO-TRÖL 2006
in the currently applicable version

Any damage or loss resulting from technical
modifications to the control unit or to the control
components are excluded from our liability.
Please read these instructions carefully before
the installation and keep them in a safe place.
Please also note the technical information in
the appendix.
To save energy and protect against scaling
if the total hardness is greater than 15 °dH
(2.5 mol/m³), the DHW temperature may be set
to a maximum of 50 °C.
If the total hardness is greater than 20 °dH
(3.58 mol/m³), we recommend using a water
treatment facility in the cold water supply line
for DHW heating, to prolong the maintenance
interval (descaling DHW heat exchanger).
