The minimum boiler water temperature
for oil and gas operation is 75 °C.
Safeguard the boiler return temperature
(minimum temperature) of 65 °C.
Set the minimum heating output for the
base load stage according to the condi-
tions of the flue system. Note that the flue
system must be suitable for the low flue
gas temperatures that may occur.
If the boiler frequently cycles in standby
mode and for partial loads below 40 %
we recommend thermally insulating the
flue gas collector, installing a motorised
flue gas damper and setting the mini-
mum boiler runtime to 10 minutes.
This extends the service life and reduces
the running costs.
Instructing the system user
The installer should instruct the user in
the operation of the system.
Operating and service documents
1.
Complete and detach the customer
registration card:
■ Hand system users their section for
safekeeping.
■ Retain the heating contractor's
section.
2.
File all parts lists, operating and serv-
ice instructions in the folder and hand
this over to the system user.
The installation instructions are no
longer required after the installation is
complete and therefore do not need
to be retained.
