30 Installing the System Piping
3.5 Testing the Water System
WARNING
Ensure that the boiler is full of water before
firing the burner. Operating the unit without
completely filling it will damage the boiler. Such
damage is not covered by the warranty, and
may result in property damage, severe personal
injury, or death.
Perform a fill test after installing the boiler’s water
system to make sure that the system has been
installed properly. Follow the instructions below to
perform a fill test on the water system.
1. Fill the system only after ensuring that the water
chemistry meets the requirements.

Note
Proper maintenance of the boiler is
required when water quality does
not meet standards. Damage caused
by poor water quality is not covered
under warranty. The table above shows
the maximum contaminant levels
allowed. If you suspect that your water
is contaminated in any way, discontinue
the use of the boiler and contact an
authorized technician or licensed
professional.

External water fill connection may be installed
on the system piping if it is required for specific
applications. See the following figure for an example
