building regulations. If the gas condensing boiler is to be
installed in a room designated for constant occupation, a
flue system that has been approved for such locations
must be allowed for.
Prior to the installation, the relevant flue gas inspector and
the waste water authority may need to be notified.
Regional approvals with regard to the flue system and the
introduction of condensate into the public sewer system

According to paragraph 10 of the Energy Savings Order
(EnEV) [Germany], the system must be correctly

annual inspection and any required maintenance. Regular
inspection and maintenance are pre-requisites for reliable
and economical operation.
These conditions are assured with a suitable hydraulic
circuit and boiler control (hydraulic connection
