CHAPTER 10 - START-UP PREPARATION

10.1. Boiler System Fluid Requirements

NOTICE
Requirements below must be met for warranty
coverage of EXALT heat exchangers. A thor-
ough cleaning of any existing system, using
approved heating system cleaning agents is
required prior to installation of the EXALT boil-
er. System should be treated with an approved
inhibitor after filling for long term protection.
WARNING
Do not use petroleum-based cleaning or seal-
ing compounds in the boiler system. Dam-
age to seals and gaskets in the system com-
ponents can occur, resulting in substantial
property damage, serious injury, or death.
NOTICE
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.

10.1.1 Boiler Fluid pH Level 6.0 to 8.0

Maintain the boiler fluid pH between 6.0 and 8.0.
Check using litmus paper or contact a water treatment
company for a chemical analysis.
If the pH does not meet this requirement, do not operate
the EXALT or leave the unit filled until the condition is
corrected.

10.1.2 Boiler Fluid Hardness Less Than 7 Grains

For areas with unusually hard water (hardness above 7
grains) consult a water treatment company.

10.1.3 Chlorinated Water

Do not use the EXALT to heat a swimming pool or spa
directly.
Maintain the chlorine level of the water at levels consid-
ered safe for drinking.

10.1.4 Flush Boiler to Remove Sediment

The installer must flush the boiler system to remove any
sediment to allow proper operation of the EXALT.
Flush the system until the water runs clean and is free
of sediment.
For zoned systems, each zone should be flushed
through a purge valve. Purge valves and isolation
valves should be installed on each zone to allow proper
flushing of the system.

10.1.5 Cleaning of Old Boiler/System:

• Drain the existing system.
• Fill system with fresh water and cleaner, place exist-
ing boiler in operation and run all zones.
• Follow manufacturer's instructions for proper clean-
er concentration and proper cleaning time.
• Thoroughly drain and flush system with fresh water
after cleaning.
• Install new boiler and fill system with fresh water
and proper amount of inhibitor.
• Verify pH and inhibitor level per inhibitor manufac-
turer's specs; add inhibitor if necessary.

10.1.6 Cleaning of New Boiler/System:

• Install new boiler and flush system with clean water
to remove any debris.
• Fill system with fresh water and proper amount of
inhibitor.
• Verify pH and inhibitor level per inhibitor manufac-
turer's specs; add inhibitor if necessary.
