1.8.1 HYDROSTATIC TEST OF
BOILERS AND SYSTEM
After completing the boiler and burner
installation, the boiler connections, fittings,
attachments and adjacent piping must be
inspected for leaks by filling the unit with water.
The pressure should be gradually increased to a
pressure just below the setting of boiler safety
relief valve(s).
Remove the boiler tube access panels (see
dimensional drawing in the boiler manual).
Inspect the tube to header joints to be certain
that all tube fittings are sealed. This is
necessary because, although the boiler is
hydrostatically tested at the factory, minor leaks
in fittings and at attachments can develop from
shipping vibration or from installation
procedures. It is often necessary to retighten
such fittings after installation and after the boiler
has been operated for some time. Replace tube
access panels before proceeding to start boiler.
