CHAPTER 10 - START-UP PREPARATION
10.1.7 Check and Test Antifreeze
For boiler systems containing antifreeze solutions, fol-
low the antifreeze manufacturer’s instructions in verify-
ing the inhibitor level and to ensure the fluid character-
istics are within specification requirements.
Due to the degradation of inhibitors over time, antifreeze
fluids must be periodically replaced. Refer to the manu-
facturer of the antifreeze for additional instructions.
10.1.8 Use of Antifreeze in the Boiler System
NEVER use automotive or ethylene glycol an-
tifreeze or undiluted antifreeze in the system
as freeze protection. This can result in sub-
stantial property damage, serious injury, or
death.
Determine the antifreeze fluid quantity using the sys-
tem water volume and following the antifreeze manu-
facturer instructions.
The water volume of the PRESTIGE Solo is approximate-
ly 3 gallons [12 L] for PRESTIGE Solo 80/110 or 5 gallons
[19 L] for PRESTIGE Solo 155/175/250 or 7 gallons [26 L]
for PRESTIGE Solo 299/399. Remember to include the
volume of the expansion tank.
Check with local code requirements for the installation
of backflow preventers or actual disconnection of the
boiler’s cold water fill or make up water supply line.
Massachusetts Code requires the installation of
a backflow preventer if antifreeze is used.
Ensure the concentration of antifreeze to water does
not exceed a 50/50 ratio.
System fluid including additives, must be prac-
tically non-toxic, having a toxicity rating or
Class of 1, as listed in Clinical Toxicology of
Commercial Products.

10.2. Filling the Boiler System
1. Close the boiler drain valve located on the bottom
of the unit and any manual or automatic air vents
in the system.
2. Open all system isolation valves.
3. Fill the boiler system to correct system pressure.
Correct pressure will vary with each application.
Typical residential system fill pressure is 12 psi.
System pressure will increase as system tem-
perature increases. Operating pressure of the
system should never exceed 25 psi.
4. Purge air and sediment in each zone of the boiler
system through the purge valve. Open air vents to
allow air to be purged from the zones.
5. Once the system is completely filled and purged of
all air and sediment, check the system pressure and
check/repair any leaks.
Unrepaired system leaks will cause continu-
al makeup water to be added to the boiler.
Continual makeup water will cause mineral
buildup within the heat exchanger, reducing
the heat transfer, causing heat buildup and
eventual heat exchanger failure. This can re-
sult in substantial property damage, serious
injury, or death.
10.3. Check Low Water Cut-Off Device
• The PRESTIGE Solo is provided with a factory in-
stalled LWCO device that monitors system pressure.
• Access the Boiler Information Menu by following
instructions in Section 9.12 on page 50. Scroll
down to see the current system pressure and verify
it is within the range given in
Section 10.2 above.
