CHAPTER 10 - START-UP PREPARATION

NOTICE
Requirements below must be met for warranty
coverage of Prestige Excellence heat exchang-
ers. A thorough cleaning of any existing sys-
tem, using approved heating system cleaning
agents is required prior to installation of the
Prestige Excellence boiler. System should be
treated with an approved inhibitor after filling
for long term protection.

10.1. Boiler System Fluid Requirements

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 6.6 to 8.5

Maintain the boiler fluid pH between 6.6 and 8.5. 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 PRESTIGE Excellence 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 Chloride Level Less Than 125 ppm (mg/L)

NOTICE
Do not fill appliance or operate with water con-
taining chlorides in excess of 125 ppm (mg/L).
Filling with fresh chlorinated water should be accept-
able since drinking water chloride levels are typically
less than 5 ppm (mg/L).
NOTICE
Do not use the PRESTIGE Excellence to heat a
swimming pool or spa directly.
10.1.4 Total Dissolved Solids (TDS) Less Than 200
ppm (mg/L)
Total Dissolved Solids are minerals, salts, metals, and charged
particles that are dissolved in water.
The greater the amounts of TDS present, the higher the cor-
rosion potential due to increased conductivity in the water.

10.1.5 Iron Level Less Than 0.5 ppm (mg/L)

The greater the amounts of iron present, the higher the cor-
rosion potential due to increased conductivity in the water.

10.1.6 Copper Level Less Than 0.1 ppm (mg/L)

The greater the amounts of copper present, the higher
the corrosion potential due to increased conductivity
in the water.
10.1.7 Conductivity Less Than 400µS/cm (at 77°F
[25°C])
A high conductivity level is an indication of high levels
of impurities which increases the potential for corrosion.

10.1.8 Flush Boiler to Remove Sediment

The installer must flush the boiler system to remove any
sediment to allow proper operation of the PRESTIGE Ex-
cellence .
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.
