Testing for gas leaks
See subsection 13.1 "Testing for gas leaks".
Carrying out a pressure test of the heating system
See chapter 10.2 "Filling the heating system".
Checking venting systems
Check the following points:
- Is the prescribed combustion air/fl ue system used?
- Have the instructions for confi guring the fl ue system as specifi ed in the relevant
Installation instruction for the fl ue gas system been observed?
- Check air intake and/or air fi lter and fl ue gas for obstruction, pollution or damage.
When an air fi lter is used the air fi lter must be replaced yearly on boilers

The conditions (eg. supply air quality) in which the boiler is installed should
be taken into account. This will show whether the frequency of replacement
should be reduced or increased. If in doubt, contact RINNAI.
