CHAPTER 10 - START-UP PREPARATION
10.1. Boiler System Fluid Requirements
Requirements below must be met for warranty
coverage of INSTINCT heat exchangers. A thor-
ough cleaning of any existing system, using
approved heating system cleaning agents is re-
quired prior to installation of the INSTINCT boil-
er. System should be treated with an approved
inhibitor after filling for long term protection.
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.
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 uid pH between 6.0 and 8.0. Check
using litmus paper or contact a water treatment com-
pany for a chemical analysis.
If the pH does not meet this requirement, do not oper-
ate the INSTINCT or leave the unit lled until the condi-
tion 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 INSTINCT 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 ush 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 ushed
through a purge valve. Purge valves and isolation
valves should be installed on each zone to allow proper
ushing 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 ush system with fresh water
after cleaning.
• Install new boiler and ll 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 ush 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.
