Инструкции По Установке для Utica Boilers UB95M-200

Continuous addition of make-up water will constantly add 

oxygen to system. Eliminate all system leaks. All system 

leaks must be repaired immediately. 

Verify expansion tank is operational and properly sized. 

Undersized expansion tanks cause relief valve weeping and 

substantial make-up water addition.

Operation of this boiler in system containing significant 

amounts of dissolved oxygen can cause severe heat 

exchanger corrosion damage.

This boiler is not designed for use in systems containing 

regular additions of make-up water. Regular additions of 

make-up water may cause severe heat exchanger damage.  

System leaks may not always be visible. Unseen system 

leak will become obvious if boiler pressure decreases when 

make-up valve is closed. 

This boiler is designed for closed loop hydronic heat system 

This boiler is not suitable for natural gravity type 

installations, or any other open type system.

Fill Water and Chemistry
Verify water used to fill system meets these requirements:
System fluid pH maintained between 7.0 and 8.0. 
Maintain water hardness below 7 grains hardness. 
Filling with chlorinated potable water is acceptable. DO 

NOT fill boiler with water containing chlorine in excess of 

100 ppm.
DO NOT use inhibitors or other additives that are not listed 

at end in this addendum.
Consult local water treatment specialist for 

recommendations if any of above requirements is outside 

stated ranges.

Clean System First
BEFORE connecting boiler to heating system, clean and 

flush system thoroughly. Verify system is free of sediment, 

flux and any residual boiler water additives.

Systems having not recommended antifreeze must be 

completely flushed to ensure no old antifreeze remains. In 

older systems obviously discolored, murky or dirty water; 

or pH reading outside acceptable range (between 7.0 and 

8.0) are indications system should be cleaned or treated. 

Thoroughly flush system with clean water to remove any 

sediment or contaminants. Sludge and iron oxide deposits 

can cause rapid breakdown of inhibitors.

Flushing with clean water. If chemical cleaners are used, 

use only those recommended for use with aluminum 

boilers. Follow chemical cleaner manufacturer’s instructions 

completely.

DO NOT mix different manufacturer’s products.
