islature.
In a similar manner, the regulations of the local building
authorities, insurers and chimney inspectors must be tak
-
en into account. When gas is used as fuel, the regulations
of the responsible gasworks must be observed and an
official authorisation may also be required.
1.5
Guarantee
Trouble-free functionality is only guaranteed when both
these and the operating instructions are meticulously ob
-
served and the boiler is regularly serviced by a qualified
engineer (maintenance contract). Repair of faults and
damage caused by contaminated operating materials
(gas, water, combustion air), unsuitable chemical addi
-
tives in the heating water, careless treatment, faulty in
-
stallation, unauthorised modifications and damage as a
result of force are not subject to our guarantee liability;
this applies also to corrosion caused by halides, e.g. em
-
anating from spray canisters, paints and varnishes, adhe
-
sives, solvents and cleaning agents.
