and biologically produced methane, VGBF..L for air.
Outlet pressure ranges:
The outlet pressure range is reached through
the use of different springs (see [Spring table –
p. 6]). The regulators are pre-set at the factory to
20 mbar (red spring).

Service life
The Pressure Equipment Directive (PED) and the
Energy Performance of Buildings Directive (EPBD)
demand regular checks on and maintenance of heat-
ing systems, in order to ensure a high level of use
in the long term, a clean method of operation and
safe function.
The service life on which the construction is based,
hereinafter referred to simply as the “service life”, is
compiled from the relevant standards. You can find
further explanations in the applicable rules and regu-
lations and on the afecor website (www.afecor.org).
This information on service life is based on using
the product in accordance with these operat-
ing instructions. The product must be serviced at
regular intervals. Once the specified service life has
been reached, the safety-related functions must be
checked in accordance with the section entitled
[Maintenance – p. 4].
If the product passes the aforementioned function
tests, you can continue to use it until the next sched-
uled maintenance operation. At this point, these tests
must be repeated.
If the product fails one of the aforementioned tests,
it must be replaced immediately.
This procedure applies to heating systems. For ther-
moprocessing equipment, observe national regula-
tions.
Service life (based on date of manufacture) in accord-
ance with EN 13611 and EN 88 for VGBF: 15 years.
Long-term use in the upper ambient temperature
range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact
manufacturer).
