INTRODUCTION

 

The Condensate Neutralization Tank is used for neutralizing condensate from condensing boilers 
that use natural gas or propane as fuel. Waste condensate, produced by the burning of these 
fuels, is potentially harmful to the environment and can corrode unprotected piping systems. The 
kit  is  used  to  neutralize  the  acidic  PH  of  the  condensate  to  ensure  the  harmful  effects  are 
minimized. 

Features and Benefits: 

 

Prevents acidic condensate from corroding pipes and sewer systems. 

 

Environmentally friendly. 

 

Fast and easy installation. 

 

Kit materials are made from corrosion resistant materials. 

 

For use on all types of Natural Gas and Propane appliances. 

 

Initial charge of neutralizer agent is included. 

 

Includes: baffles designed to channel flow thoroughly for complete neutralization, integral 
bypass to prevent condensate backflow into appliance, NPT connections with unions for fast 
and versatile installation. 

 

INSTALLATION INSTRUCTIONS

 

 

NOTE: 

Check  with  your  local  water  authority  for regulations  regarding  discharge of  treated 

condensate into a drain or sewer system.

RISK OF DAMAGE TO APPLIANCE!

 

Follow these instructions carefully to avoid damage to equipment and appliances. 

The Condensate Neutralization Tank can be installed using either of the following methods: 

  Neutralization  tank  is  installed  such  that  the  inlet  and discharge  of  the  tank are at  a  lower 

elevation than the AERCO condensate trap outlet.  This can be achieved by: 

a) Installing the Neutralization Tank in a pit (see Figure 2).  

b)  Elevating  the  AERCO  boiler/water  heater(s)  and  the  AERCO  condensate  trap(s)  (see 
Figure 3).   

  A  condensate  pump  is  used  to  lift the  condensate from the appliance  to the  Neutralization 

Tank (Figure 4).       

Do not

 allow exhaust flue gases to vent through the Neutralization Tank.  Flue gas leakage can 

cause injury or death from carbon monoxide.  Ensure the AERCO condensate trap is properly 
installed with the boiler/water heater, upstream of the  Neutralization Tank.  See the boiler/water 
heater installation manual for condensate trap installation instructions.  

Connection  to  the  appliance  and  Neutralization  Tank  must  be  installed  to  ensure  that  no 
condensate backflow into the appliance can occur
