Visual inspection for general signs of corrosion

- Check all gas and water pipes for signs of corrosion.
- Replace any pipes that are corroded.

Measuring the ionization current

See subsection 12.5 "Measuring the ionization current".

Measuring the inlet gas pressure

See subsection 6.4.1 and .2 "Gas connection with natural gas" and "Gas connection
with propane".

Testing for gas leaks

See subsection 12.1 "Testing for gas leaks".

Carrying out a pressure test of the heating system

See chapter 9.2 "Filling the heating system".

Checking venting systems

Check the following points:
- Is the prescribed combustion air/flue system used?
- Have the instructions for configuring the flue system as specified in the relevant
Installation instruction for the flue gas system been observed?
- Check air intake and/or air filter and flue gas for obstruction, pollution or damage.
When an air filter is used the air filter must be replaced yearly on boilers
operating in normal circumstances.
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.
