Appendix
(cont.)
The installation of a condensing boiler may need to be notified to
and approved by your local gas supply utility.
In some regions, permits may be required for the flue system and
condensate drain into the public sewage system.
In some countries, the relevant flue gas inspector and water authori-
ties must be informed prior to commencing the installation.
We recommend that maintenance and cleaning procedures are per-
formed annually. As part of the maintenance procedure, check the
correct function of the entire system. Remedy any faults.
