CHAPTER 10 - START-UP PREPARATION
10.1. Boiler System Fluid Requirements
NOTICE
Requirements below must be met for warranty
coverage of INSTINCT heat exchangers. A thorough
cleaning of any existing system, using approved
heating system cleaning agents is required prior to
installation of the INSTINCT boiler. System should
be treated with an approved inhibitor after filling for
long term protection.
Do not use petroleum-based cleaning or sealing
compounds in the boiler system. Damage to seals
and gaskets in the system components can occur,
resulting in substantial property damage, serious
injury, or death.
NOTICE
System fluid including additives, must be practically
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 INSTINCT 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
g rains) consult a wat er tr eatment compan y .
10.1.3 Chlorinated Water
Do not use the INSTINCT to heat a swimming pool or
spa directly.
Maintain the chlorine level of the water at levels
consider ed saf e f or drink ing .
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 INSTINCT.
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
existing boiler in operation and run all zones.
• Follow manufacturer’s instructions for proper
cleaner 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
manufacturer’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
manufacturer’s specs; add inhibitor if necessary.
