Start-up   

Check/control fill water chemistry

Conduct water quality testing prior to 
installing the appliance.  Various solutions 
are available to adjust water quality.

Hardness between 5 and 12 grains per gallon

1.  Consult local water treatment companies for hard water 

areas (above 12 grains per gallon hardness).

2.  Hardness levels that are above 12 grains/gallon can lead 

to lime scale buildup throughout the boiler system.  If the 
fill water is below 5 grains/gallons, usually due to use of a 
water softener, it is recommended to mix in some potable 
water at the inlet to increase the hardness of the water to 
above 5 grains/gallons.

pH between 6.5 and 8.5

1.  pH levels below 6.5 can cause an increase in the rate of 

corrosion.  pH of 8.5 or higher can potentially cause lime 
scale buildup.

Total Dissolved Solids (TDS) less than 350 ppm

1.  Total dissolved solids are all minerals, salts, metals, and 

charged particles that are dissolved in water.

2.  The greater the amounts of TDS present, the higher the 

corrosion potential due to increased conductivity in the 
water.

Chloride concentration less than 150 ppm

1.  Do not fill boiler or operate with water containing 

chlorine in excess of 150 ppm.

2.  Filling with fresh drinking water should be acceptable.

3.  Do not use the boiler to directly heat swimming pool or 

spa water.

IMPORTANT

Fill water

The manufacturer recommends the following for properly 
filling your boiler with the appropriate water chemistry for 
closed loop boilers.  Good fill water quality will help extend 
the life of the appliance by reducing the effects of lime scale 
buildup and corrosion in closed loop systems.

Pre-Commissioning Cleaning

1.  Prior to fill and start-up, flush the entire heating system.

2.  Clean the entire heating system with an approved pre-

commissioning cleaner (comparable to Sentinel X300 or 
X400 and Fernox F3 or DS40) in accordance with the 
manufacturer’s recommendation to remove debris and 
prolong the life of the heat exchanger.

3.  Clean all water filtering devices in the system.

4.  Flush the cleaning solution out of the entire system and 

refill.

  •  Monitoring pH, chlorides, TDS, and hardness 

  

levels can prolong the life of the appliance by reducing 

  

lime scale buildup, corrosion, and erosion.  Check for 

  

leaks to ensure that fresh water is not entering the 

  

system.

 

• 

Continual fresh makeup water will reduce boiler life.

 

• 

Mineral buildup in the heat exchanger reduces heat 

  

transfer, overheats the stainless steel heat exchanger, 

  

and causes failure.

 

• 

The addition of oxygen carried in by makeup water 

  

can cause internal corrosion in system components.

 

• 

Leaks in the boiler or piping must be repaired at once 

  

to prevent excessive makeup water.  For this purpose, 

  

it is recommended to install a water meter to easily 

  

check the amount of makeup water entering the 

  

system.  Makeup water volume should not exceed 5% 

  

of the total system volume per year.  Note:  When 

  

makeup water is added, make sure the chemical 

  

additives are added to maintain the correct level.

  •  An approved multi-metal corrosion inhibitor 

 

 

(comparable to Sentinel X100 or Fernox F1) is 

  

recommended at the correct concentration and in the 

  

manner recommended by the manufacturer.

Do not use petroleum based cleaning or 
sealing compounds in the boiler system.  
Gaskets and seals in the system may be 
damaged.  This can result in substantial 
property damage.

DO NOT use "homemade cures" or "boiler 
patent medicines".  Serious damage to 
boiler, personnel, and/or property may 
result.
