DIELECTRIC ISOLATION & ANTIFREEZE PROTECTION 

ADDENDUM

APPENDIX A - WATER QUALITY, WATER TREATMENT AND FREEZE PROTECTION

WARNING

Follow these instructions to prevent damage to 

boiler’s heat exchanger caused by inadequate 

dielectric isolation, incorrect water treatment or 

antifreeze application. Failure to comply could result 

in death or serious injury.

!

  

• Install boiler so gas ignition system components are 

protected from water (dripping, spraying, rain, etc) 

during appliance operation and service (circulator re-

placement, etc).

• DIELECTRIC ISOLATION

 

Two (2) 1-1/4” X 1-1/4” Female to female dielectric 

isolation unions are shipped loose in boiler parts bag. 

Install Dielectric Isolation unions at boiler supply line 

and return line. Install isolation

 ttings nearest boiler 

prior to system piping connections.

• WATER TREATMENT and ANTIFREEZE 

PROTECTION

MUST be applied for ALL aluminum series high
