Testing system pressure: adding make-up water and venting the system

3.4.1 When to test system pressure?

Newly added make-up water tends to reduce its volume
within the first few days due to elimination of entrained
air. This may lead to air build-up and possible system
noise.
Check newly started systems daily for system
pressure and bleed radiators if necessary.
Check system pressure on a monthly basis and add
make-up water automatically and possibly bleed the
radiators.

3.4.2 Testing system pressure

The system operating pressure must be at least 12 to
15 psi (1 bar). The specific recommended
The specific recommended test pressure can be
found on page 2. of this manual.
Read off the pressure (psi) and temperature (°F) at
the P & T guage located at the supply side of the
boiler.
When the system pressure drops below 12 to 15 psi,
add make-up water to the system.
